More particularly, fibrous structures comprising a user contacting surface comprising a first region comprising a surface treating composition and a second region comprising a lotion composition are provided.

Description

with the intention of maximizing the transfer of the lotion composition. The formulators have added anti-migratory material, such as a quaternary ammonium compound to the fiber supply so as to coat the fibers with the quaternary ammonium compound. The fibrous structure formed by the fibrous layer tends to mitigate the migration of a lotion composition subsequently applied to the fibrous structure. The function of the quaternary ammonium compound and the level at which it is used do not cause softening of the fibrous structure. Also known in the industry is the method of adding quaternary ammonium compounds and / or silicones and / or other types of agents to the fiber supply to unclog the fibers. None of the fibrous structures indicate or suggest to treat the surface of the fibrous structure with a composition for surface treatment and a lotion composition so that the contacting surface with the user comprising a first region of composition for the treatment of surface and a second region comprising a lotion composition is produced on the surface of the fibrous structure. Accordingly, there remains a need to provide a fibrous structure comprising a surface treatment composition such as a softening composition and a lotion composition so that the contacting surface with the user comprising a first region including the composition for the treatment of surfaces and a second region comprising the lotion composition, there is produced on a surface of the fibrous structure, a hygienic product of single-ply or multi-ply tissue paper made thereof and processes for its manufacture.

DETAILED DESCRIPTION OF THE INVENTION Definitions As used herein, the term "fiber" means an elongated particulate whose apparent length greatly exceeds its apparent diameter, i.e., a length-to-diameter ratio of at least about 10. Fibers that are not common are common. they have a circular cross section; the "diameter", in this case, can be considered to be the diameter of a circle that has an area in cross section equal to the cross-sectional area of the fiber. More specifically, as used herein, "fiber" refers to paper fibers. The present invention contemplates the use of a variety of papermaking fibers, such as, for example, natural fibers or synthetic fibers, or any other suitable fiber, and any combination thereof. The natural papermaking fibers that are used in the present invention include animal fibers, minerals, vegetables and mixtures of these. The animal fibers, for example, can be selected from the group comprising: wool, silk and mixtures thereof. Plant fibers, for example, can be derived from a plant selected from the group comprising: wood, cotton, cotton linters, flax, sisal, abacus, hemp, hesperaloe, jute, bamboo, bagasse, kudzu, corn, sorghum, gourd, agave, scourer and mixtures of these. Wood fibers; often called wood pulps include chemical pulps, such as Kraft (sulfate) and sulfite pulps, and also mechanical and semimechanical pulps including, for example, crushed wood, thermomechanical pulp, chemomechanical pulp (CMP, for its acronyms in English), pultru quimiotermomecánica (CTMP, for its acronym in English) and neutral sulfite pulp (NSCS, for its acronym in English). However, chemical pulps may be preferred since they impart a superior tactile feel of softness to the sheets of tissue paper made therefrom. Pulps derived from deciduous trees (hereinafter also called "hardwoods") and coniferous trees (hereinafter also called "softwoods") can be used. The hardwood and softwood fibers can be blended, or alternatively, layered to provide a layered and / or layered fibrous structure. U.S. Pat. num. 4,300,981 and U.S. Pat. no. 3,994,771 are incorporated herein by reference for purposes of describing the stratification of hardwood and softwood fibers. As well fibers derived from recycled paper that can contain one or all of the mentioned fiber categories and other non-fibrous materials such as fillers and adhesives that facilitate the original papermaking process are useful. The fibers of wood pulp may be short (characteristic of hardwood fibers) or long (characteristic of softwood fibers). Some non-limiting examples of short fibers include fibers derived from a source of fibers selected from the group comprising acacia, eucalyptus, maple, oak, poplar, birch, poplar, alder, ash, cherry, elm, American walnut, poplar, chewing gum, walnut, white acacia, sycomom, beech, catalpa, sassafras, melina, albizia, kadam, magnolia. Some non-restrictive examples of long fibers include those derived from pine, spruce, white spruce, Canadian larch, hemlock, cypress and cedar. Softwood fibers derived from Kraft processes, which originate in more Nordic climates, are preferred. These are known as softwood kraft pulps (NSK). The synthetic fibers can be selected from the group comprising wet spun fibers, dry spun fibers, melt spun fibers (including melt blown), synthetic pulp fibers and mixtures thereof. For example, synthetic fibers may be composed of cellulose (often referred to as "rayon"); cellulose derivatives, such as esters, ether or nitroso derivatives; polyolefins (including polyethylene and polypropylene); polyesters (including polyethylene terephthalate); polyamides (often referred to as "nylon"); acrylics; non-cellulosic polymeric carbohydrates (such as starch, chitin and chitin derivatives, eg, chitosan); and mixtures of these. As used herein, "fibrous structure" means a structure composed of one or more fibers. Some non-restrictive examples for fibrous structure manufacturing processes include the wet laying and laying processes in the air. In general, said processes include the steps of preparing a fiber composition, generally known as fiber pulp in wet, wet or dry laying processes, and then depositing a plurality of fibers on a forming or forming wire. band so as to form an embryonic fibrous structure, dry and / or join the fibers to form a fibrous structure, and / or process the fibrous structure to form a finished fibrous structure. For example, in common papermaking processes, the finished fibrous structure is the structure that is wound onto the reel at the end of the papermaking process, but before it becomes a tissue paper hygienic product. The "tissue paper hygiene product" comprises one or more fibrous structures, transformed or not, but which can nevertheless be used as cleaning implements after urinating and defecating (toilet paper), for otorhinolaryngological discharges (disposable handkerchief and / or handkerchiefs disposable), and multifunctional absorbent and cleaning uses (wipes and / or absorbent linens). In one example, a multi-sheet disposable tissue containing a lotion composition having a caliper of between about 0.1 and 0.4 mm is provided in accordance with the present invention. As used herein, "sheet" or "sheets" refers to a finished individual fibrous structure which, optionally, can be placed in a substantially contiguous, face-to-face relationship with other sheets to form a product of fibrous structure or a hygienic product of tissue paper finished with multiple sheets. It is also contemplated that a single fibrous structure can efficiently form two "sheets" or multiple "sheets", for example, by folding it over itself. As used herein, "surface of a fibrous structure" refers to the portion of the fibrous structure that is exposed to the environment. In other words, the surface of a fibrous structure is the portion of fibrous structure that is not completely surrounded by other portions of the fibrous structure. "Surface contacting the user" as used herein means the portion of the fibrous structure and / or composition for surface treatment and / or lotion composition directly and / or indirectly present on the surface of the fibrous and exposed structure to the external environment. In other words, it refers to the surface formed by the fibrous structure including any composition for surface treatment and / or lotion composition present directly and / or indirectly on the surface of the fibrous structure that is in contact with the opposite surface while it is used by a user. For example, it refers to that surface formed by the fibrous structure including any composition for surface treatment directly and / or indirectly present on the surface of the fibrous structure that makes contact with a user's skin when said user cleans his skin with the fibrous structure of the present invention. In one example, the surface contacting the user, especially in the case of a textured and / or structured fibrous structure, such as a fibrous structure dried with through air and / or a fibrous structure etched, may include raised areas and recessed areas of the fibrous structure. In the case of a fibrous structure dried with passant air and densified with pattern, the raised areas may be knuckles and the hollowed areas may be pads and vice versa. Accordingly, the knuckles can directly and / or indirectly comprise the lotion composition and the pads can comprise the composition for surface treatment and vice versa so that when a user places the fibrous structure that makes contact with their skin, both the composition of lotion as the composition for the treatment of surfaces make contact with the skin of the user. A similar case applies to fibrous structures engraved with engraved areas that may include lotion composition in direct and / or indirect manner while non-engraved areas may comprise composition for surface treatment and vice versa. In one example, the surface contacting the user comprises regions of a size such that two or more different regions (including different compositions) are exposed to an opposite surface during use. In other words, a surface of a fibrous structure substantially covered (on a microscopic scale) by a lotion composition but completely covered on a macroscopic scale, by said lotion composition so that the user's skin only comes in contact with the composition of lotion, does not contain two different regions on the surface that makes contact with the user. In one example, the surface contacting the user may include an outer layer of a multilayer fibrous structure in which the outer layer may comprise a composition for surface treatment and / or a lotion composition. The surface contacting the user may be present in the fibrous structure and / or tissue paper hygienic product before being used by the user and / or the surface contacting the user may be created / formed before and / or during the use of the fibrous structure and / or tissue paper hygienic product by a user, such as when the user applies pressure to the fibrous structure and / or to the tissue paper hygienic product when the user orients the fibrous structure and / or the product hygienic tissue paper towards your skin. All percentages and proportions are calculated by weight, unless otherwise indicated. All percentages and proportions are calculated based on the total composition, unless otherwise specified. Unless otherwise specified, all levels of the component or composition are expressed in reference to the active level of that component or composition, and are exclusive of impurities, for example, solvents. residuals or byproducts, which may be present in commercially available sources.

In one example, the second region 16 is in contact and / or covers an area less than all or practically all of the surface area of the surface of the fibrous structure 18. When both regions cover an area smaller than substantially the entire surface area of the fibrous structure 18, that region may take the form of a plurality of different areas. As illustrated in Figure 2, the first region 14 is in contact and / or covers substantially the entire surface area of the fibrous structure 18 and the second region 16 is in contact and / or covers an area less than substantially all the surface area of the fibrous structure 18. The first region 14 may have the form of a continuous or substantially continuous network and the second region 16 may be in the form of a plurality of discrete spaced areas through the continuous or substantially continuous network of the first region. 14. Any region may be in contact with the other. As illustrated in Figure 3, the second region 16 is in contact with the first region 14 so that the first region 14 is placed between the second region 16 and the surface of the fibrous structure 18. The second region 16 may be present. over an area less than the entire surface area of the first region 14. The second region 16 may be present over the first region 14 in the form of one or more distinct areas. As illustrated in Figures 1, 4 and 5, the portions of the second region 16 are in contact with the first region 14 so that the second region 16 and the first region 14 are directly in contact with the surface of the structure fibrous 18. Also as illustrated in the Figures. 4 and 5, a portion of the second region 16 is not in contact with the first region 14. Figures 4 and 5 also show that an area below substantially the entire surface area of the surface of the fibrous structure 18 are in contact or covered by the first region 14 and the second region 16. In these examples, the surface contacting the user 12 includes a third region, mainly the surface of the fibrous structure 18 as well as the first region 14 and the second region 16. Figure 6 is a schematic representation of another example of fibrous structure in accordance with the present invention.

Composition for the treatment of surfaces For the purposes of the present invention, a composition for the treatment of surfaces is one that improves the tactile sensation of a surface of a fibrous structure perceived by a user holding a fibrous structure and / or hygienic product of Tissue paper that comprises the fibrous structure and rubs it on your skin. Said perceptible tactile smoothness can be characterized in a limiting way by friction, flexibility and softness as well as by subjective properties, such as the feeling of lubricity, velvety, silky or softness similar to that of a flannel. The composition for surface treatment may or may not be transferable. In general, this is practically non-transferable. The composition for the surface treatment can increase or reduce the surface friction of the surface of the fibrous structure, especially of the surface of the fibrous structure in contact with the user. Generally, the surface treatment composition will reduce the surface friction of the surface of the fibrous structure as compared to the surface of the fibrous structure that does not comprise said composition for the surface treatment. The surface treatment composition may exhibit a wet tension less than or equal to the surface tension of the lotion composition so as to minimize the extent of the lotion composition that comes into contact with the surface treatment composition. The composition for surface treatment comprises an agent for surface treatment. The composition for surface treatment, while being applied to the fibrous structure, may comprise at least about 0.1% and / or at least 0.5% and / or at least about 1% and / or at least about 3% and / or at least about 5% to about 90% and / or about 80% and / or about 70% and / or about 50% and / or about 40% by weight of surface treatment agent. In one example, the composition for surface treatment comprises between about 5% to 40% by weight of the surface treatment agent. The composition for surface treatment present on the fibrous structure and / or the tissue paper hygienic product comprising the fibrous structure of the present invention, may comprise at least 0.01% and / or 0.05% and / or 0.1% of the basis weight total agent for surface treatment. In one example, the fibrous structure and / or tissue product of tissue paper may comprise from about 0.01% to about 20% and / or from about 0.05% and 5% and / or from about 0.1% to about 10% and / or from approximately 0. 01% to about 5% and / or from about 0.1% to about 2% of the total basis weight of the composition for surface treatment. In one example, the surface treatment composition of the present invention is a microemulsion of a surface treatment agent (e.g., an aminofunctional polydimethylsiloxane) in water. In said example, the concentration of agent for surface treatment can be present in percentages between 3% and 60% and / or between 4% and 50% and / or between 5% and 40%. Some non-limiting examples of such microemulsions are those marketed by Wacker Chemie, Dow Corning and / or General Electric Silicones. Some non-limiting examples of surface treatment agents are those selected from the group comprising: polymers such as polyethylene and derivatives thereof, hydrocarbons, waxes, oils, silicones (polysiloxanes), quaternary ammonium compounds, fluorocarbons, allies substituted with C 0 to C 22 chains, alkenes substituted with C 10 to C 22 chains, in particular derivatives of alcohols and fatty acids (such as fatty acid amides, fatty acid condensates and fatty alcohol condensates), polyols, polyol derivatives ( as esters and ethers), sugar derivatives (such as ethers and esters), polyglycols (such as polyethylene glycol) and mixtures thereof.

Some non-limiting examples of suitable silicones (polysiloxanes) are those selected from the group comprising: polydimethylsiloxanes, aminosilicones, cationic silicones, quaternary silicones, silicone betaines and mixtures thereof. Some non-limiting examples of polysiloxanes and / or suitable monomeric / oligomeric units are those selected from compounds containing monomeric siloxane units with the following structure: wherein R1 and R2, in each monomeric independent siloxane unit may also independently be hydrogen or alkyl, aryl, alkenyl, alkaryl, aralkyl, cycloalkyl, halogenated hydrocarbon or other radical. Any of these radicals can be substituted or unsubstituted. The radicals R1 and R2 of any particular monomer unit may be different from the functional groups of the adjacent monomer unit. On the other hand, the polysiloxane can be straight chain, branched chain or have a cyclic structure. The radicals R1 and R2 can also independently be other siliceous functional groups such as, but not limited to, siloxanes, polysiloxanes, silanes and polysilanes. The radicals R1 and R2 can have any of a variety of organic functional groups, including, for example, alcohol, carboxylic acid, phenyl and amines. The end groups can be reactive (alkoxy or hydroxyl) or non-reactive (trimethylsiloxy). The polymer can be branched or unbranched. As an example, the alkyl radicals are methyl, ethyl, propyl, butyl, pentyl, hexyl, octyl, decyl, octadecyl and the like. As an example, the alkenyl radicals are vinyl, alilo and the like. As an example, the aryl radicals are phenyl, diphenyl, naphthyl and the like. As an example, the alkaryl radicals are tolyl, xylyl, ethylphenyl and the like.

The lotion compositions may be heterogeneous. They may contain solids, gel structures, polymeric material, a multiplicity of phases (such as an oily phase and an aqueous phase) and / or emulsified components. It may be difficult to accurately determine the melting temperature of the lotion composition, i.e. it may be difficult to determine the transition temperature between the liquid form, the quasi-liquid form, the quasi-solid form and the solid form. The terms melting temperature, melting temperature, transition point and transition temperature are used interchangeably herein and have the same meaning. The lotion compositions can be semi-solid, high viscosity so that they practically do not flow without activation for the duration of the product or of the gel structures. The lotion compositions can be reduced with friction and / or They can change their viscosity around the temperature of the skin to facilitate its transfer and extension on a user's skin.

A transferable lotion composition comprises at least one component capable of transferring during use to an opposing surface such as the wearer's skin. In one example, at least 0.1% of the transferable lotion present on the surface in contact with the user is transferred to the user's skin during use. The amount of transferable composition that is transferred to the user's skin during use can be determined by known methods such as that of removing a strip from the wearer's skin three times, after he has used the fibrous structure and / or tissue paper hygienic product, using Tegaderm strips, available from 3M, and then analyzing the strips to determine their content of transferable composition or a component within the transferable composition assuming that all components of the transferable composition are transferred in equal proportions.

For example, the lotion composition should be exposed to a temperature greater than about 35 ° C before a significant amount of the lotion composition is melted (eg, more than 30%, 40% 50% and / or 60%). %). This percentage can be expressed as: (1) 2 2/1 1 is equal to or greater than about 1 and / or equal to or greater than about 4 and / or equal to or greater than about 9; and / or (2) 2 is equal to or greater than about 30 J / g, 40 J / g and / or equal to or greater than about 60 J / g (especially if 1 is 0) where: is the energy required to raise the temperature of the lotion composition from 15 ° C to 35 ° C; 2 is the energy required to raise the temperature of the lotion composition from 35 ° C to the temperature at which the lotion composition is completely liquid or in which no further melting occurs below 100 ° C in the if the lotion composition contains components that only fuse at temperatures greater than 100 ° C. ?? it is measured by means of the DSC technique using standard parameters known to the experts in the industry. The DSC data is obtained using an instrument for DSC Thwing Albert 2920, calibrated with a standard of Indian metal with a melting start temperature of 156.6 ° C and a heat of fusion of 6.80 calories per gram, as described in the literature. The sample is first heated up to 100 ° C with a speed of 10 ° C / min., Equilibrated for 5 minutes at 100 ° C, cooled down to -30 ° C at a speed of -2.5 ° C / min., Equilibrated to -30 ° C for 5 minutes and then heated from -30 ° C to +100 ° C at a speed of 2.5 ° C / min. to evaluate the fusion behavior. For the determination of ?? 1 and ?? 2 the final heating ramp is used. ?? 1 is the area between the differential scanning calorimetry curve and the initial values between 15Â ° C and 35Â ° C and ?? 2 is the area between the DSC curve and the initial values between 35Â ° C and the temperature at which the lotion composition is fully liquid or where no melting occurs below 100 ° C in the case where the lotion composition contains components that are fused to more than 100 ° C. As an example, a lotion composition of the present invention comprising about 40% stearyl alcohol, about 30% mineral oil and about 30% petrolatum has a value of ?? 2 / ?? 1 >; 9 and a value of ?? 2 > 60 J / g.

A vehicle may be present in the composition for the surface treatment and / or the lotion composition, especially during the application of the surface treatment composition and / or the fibrous structure. The vehicle can dissolve a component (true solution or micellar solution) or the component can be dispersed therein (dispersion or emulsion). The vehicle of a suspension or emulsion is generally its continuous phase. This means that other components of the dispersion or emulsion are dispersed in the vehicle at the molecular level or as separate particles.

Processes for the treatment of fibrous structures and / or tissue paper hygiene products to. Composition for surface treatment: Any suitable contact or contact-free application to apply the composition for the treatment of surfaces, such as spray printing, spoiling, stamping, printing, slot extrusion, rotogravure printing, flexographic printing, offset printing, stencil printing, masking or stencil application processes and mixtures of these, can used to apply the composition for the surface treatment to the fibrous structure and / or tissue paper hygienic product and / or the lotion composition present on a surface of the fibrous structure and / or tissue paper hygienic product. The surface treatment compositions can be applied to the fibrous structure and / or to the tissue paper hygienic product, before, at the same time or after applying the lotion composition to the fibrous structure and / or to the tissue paper hygienic product. The surface treatment composition can be applied during the papermaking and / or conversion process, especially if it is applied to the outer layer of a layered fibrous structure and / or tissue paper hygienic product comprising said fibrous structure at layers. In one example, the surface treatment composition is applied by an application process that provides a relatively high surface area coverage on the surface of the fibrous structure and / or the tissue paper hygienic product. Examples of such suitable application processes include, but are not limited to, printing, slot extrusion and / or fine particle spray printing (although spray printing has the disadvantage of producing aerosols if it is desired to cover a large area) . b. Lotion Composition: Any contact or contact-free application suitable for applying the lotion composition, such as spray-printing, scooping, stamping, printing, slot extrusion, rotogravure printing, flexographic printing, offset printing, Stencil printing, masking or stenciling processes and mixtures thereof, can be used to apply the lotion composition to the fibrous structure and / or tissue paper hygienic product and / or the lotion composition present on a surface of the structure fibrous and / or tissue paper hygienic product. The lotion composition can be applied to the fibrous structure and / or to the tissue paper hygienic product, before, at the same time or after applying the composition for surface treatment to the fibrous structure and / or to the tissue paper hygienic product. In one example, the lotion composition is applied to the surface treatment composition present on the surface of the fibrous structure and / or tissue paper hygienic product. In one example, the lotion composition is applied by an application process that provides a relatively low surface area coverage on the surface of the fibrous structure and / or tissue paper hygienic product and / or on the surface treatment composition. present on the surface of the fibrous structure and / or tissue paper hygienic product so that the regions of the composition for the surface treatment and the lotion composition regions produce the surface in contact with the user. Examples of suitable application processes include, in a non-exhaustive manner, spraying printing, especially spraying printing with rotating discs, printing, slot extrusion in strips and / or other patterns. In one example, the surface treatment composition can be added to a fiber supply that will form an outer layer of a multilayer fibrous structure. The lotion composition can be applied to the surface formed by the outer layer of the multilayer fibrous structure. In one example, the composition for surface treatment is applied to the surface of the fibrous structure during the process of making said structure, such as before and / or after drying. The lotion composition can then be applied to the composition for the treatment of surfaces on the surface of the fibrous structure during the conversion process. In one example, the composition for the surface treatment contains less than about 5% and / or less than about 3% and / or less than about 1% and / or less than about 0.5% moisture upon application of the lotion.

Examples of fibrous structures Fibrous structure Example 1: A first fibrous structure is a conventional wet-pressed, homogeneous, dry-creped, fibrous structure with a basis weight of about 15.4 g / m2. The fibrous structure has a composition of approximately 40% Northern Softwood Kraft and 60% eucalyptus. Four folds of fibrous structure are combined in a structure in an off-line operation to produce a tissue paper hygienic product. The tissue paper hygienic product of 4 sheets has a basis weight of approximately 60 g / m2, a thickness of approximately 0.3 mm, a machine direction resistance of approximately 504 g / cm (1280 g / in), a resistance in the direction about 240 g / cm (610 g / in), and a wet burst of about 200 g. It contains a wet strength agent and a dry strength agent.

Fibrous structures - Example 2: A second fibrous structure is a conventional fibrous structure, stratified, creped dry with a basis weight of approximately 14.6 g / m2. The outer layer contains approximately 100% eucalyptus fibers while the inner layer is composed of a mixture of approximately 85% softwood Kraft coniferous, 10% CTMP and approximately 5% eucalyptus fibers. Both layers have the same base weight (symmetric stratification). Four folds of the fibrous structure are combined in an off-line combination operation to form a tissue paper hygienic product so that the eucalyptus layer is present on two of the outer surfaces of the four-ply tissue paper toilet product. The tissue paper hygienic product of 4 sheets has a basis weight of about 60 g / m2, a thickness of about 0.3 mm, a resistance in the machine direction of about 465 g / cm (1180 g / inch), a resistance in the direction about 220.5 g / cm (560 g / inch), and a wet burst of about 200 g. It contains a wet strength agent and a dry strength agent.

Fibrous structure Example 3: A third fibrous structure is formed from an aqueous Northern Softwood Kraft (NSK) pulp of a consistency of about 3% made using a conventional pulp mixer and passed through a raw material pipe to the box input of the Fourdrinier. A 1% dispersion of Kymene 557 LX from Hercules is prepared and added to the NSK raw material supply line at a rate sufficient to supply 0.8% Kymene 557 LX based on the dry weight of the final sanitary tissue. The absorption of the resin for the permanent resistance in the wet state is increased by passing the treated pulp through an in-line mixer. An aqueous solution of carboxymethylcellulose (CMC) dissolved in water and diluted to a Concentration of the solution at 1% is then added to the NSK raw material supply line after the in-line mixer at an index of approximately 0.1% CMC by weight based on the dry weight of the final sanitary tissue. The aqueous pulp of NSK fibers passes through a centrifugal pump of raw material to help distribute the CMC. An aqueous dispersion of dimethyl ammonium methyl sulfate (DTDMAMS) dispersion (76 ° C (170 ° F)) at a concentration of 1% by weight is added to the NSK raw material pipe at a rate of about 0.1% by weight of DTDMAMS based on the dry weight of the final sanitary tissue. An aqueous pulp of eucalyptus-bleached kraft fibrous pulp fibers (from Aracruz-Brazil) of approximately 1.5% by weight is formed using a conventional pulp mixer and is passed through a raw material pipe to the Fourdrinier inlet box. . This cargo of eucalyptus is coupled with the NSK pulp in the fan pump where both are diluted with fresh water to a consistency of approximately 0.2%. An aqueous pulp of bleached eucalyptus kraft fibrous pulp fibers (from Aracruz-Brazil) of about 3% by weight is formed using a conventional pulp mixer. The eucalyptus pulp passes to a second pump head machine where diluted with white water to achieve a consistency of approximately 0.2%. The NSK / eucalyptus and eucalyptus pulps are directed to a multi-channel input box suitably equipped with separation sheets to keep the streams as separate layers until they are discharged onto a mobile Fourdrinier wire. A three-chamber input box is used. The eucalyptus pulp containing 48% of the dry weight of the fibrous structure is directed to the chamber leading to the layer in contact with the wire, while the NSK / eucalyptus pulp comprising 52% (27-35% NSK and 17%). -25% eucalyptus) of the dry weight of the final paper is directed to the chamber leading to the central and inner layer. NSK / eucalyptus and eucalyptus pulps are combined at the point of unloading the input box into a composite pulp. The composite pulp is discharged onto the moving Fourdriner wire and drained with the help of a deflector and vacuum boxes. The wet embryonic fibrous structure is transferred from the Fourdrinier wire, to a fiber consistency of about 17% by weight at the transfer point, to a patterned drying cloth. The drying fabric is designed to produce a densified tissue paper with a pattern with discontinuous, low density deviated areas disposed within a continuous network of high density areas (knuckles). This drying fabric is formed by molding an impermeable resin surface onto a mesh of support fibers. The support fabric is a double layer mesh of 48 x 52 filaments. The difference in thickness of the resin mold is approximately 0.203 μ? (8 thousand) above the support fabric. The knuckle area is approximately 35-50% and the open cells remain at a frequency of approximately 438-3625 cm2 (68-562 per square inch). It is possible to obtain greater drainage by means of a vacuum drain until the fibrous structure reaches a consistency of approximately 23-27%. Still in contact with the pattern forming fabric, the patterned fibrous structure is pre-dried with through air until it reaches a fiber consistency of about 60% by weight. The semi-dry fibrous structure is then adhered to the surface of a Yankee dryer with a spray curling adhesive comprising a 0.250% aqueous solution of polyvinyl alcohol. The curling adhesive is supplied to the surface of the Yankee at a ratio of 0.1% adhesive solids based on the dry weight of the fibrous structure. Prior to dry curling of the fibrous structure with a blade from the Yankee dryer, the fiber consistency increased up to about 98%. After the curling blade, the fibrous structure is calendered across its entire width with a steel-to-rubber calender roller operating at a load of 2-3.5 MPa (300-500 psi). The tissue paper obtained has an approximate basis weight of about 20-25 g / m2, a total dry tension of a sheet between 98 and 146 g / cm (250 and 370 g / inch), a wet burst of a sheet between 14 and 25 g / cm (35 and 65) g / inch) and a two-leaf gauge of approximately 0.04 - 0.05 cm (0.015-0.020 inches). The resulting tissue paper is then combined with a similar sheet to form a two-leaf, curled, pattern-densified tissue paper such that the eucalyptus fibers are outwardly oriented and calendered between two smooth steel calender cylinders. . Then the leaves of the product are joined using a mechanical wheel to join the leaves to ensure that both sheets remain together. The resulting two-ply tissue paper has a) a total basis weight of about 39-50 g / m2; b) a total dry tension of two sheets between 177 and 275 g / cm (450 and 700 g / inch); c) a wet burst of two sheets between 39 and 51 g / cm (100 and 130 g / inch); d) a caliber of 4 sheets of approximately 0.51 and 0.89 mm. The fibrous structures described above can be used in combination with any of the treatment processes and lotion compositions described below.

Conversion of the fibrous structures of Examples 1-3: The original coil is then converted into a tissue paper hygienic product. The original multi-leaf coil is unrolled and calendered between two smooth steel calender rollers followed by high-pressure embossing to achieve the joining of the sheets. The fibrous structure in almost its entirety is practically not affected by the high pressure stamping. The composition for the surface treatment and the lotion composition are applied to the fibrous structure as described below. Finally, the fabric was cut in the direction of the machine, followed by cuts in the cross direction on canvases of approximately 21 cm x 21 cm, folded, stacked in stacks of 9 canvases and packaged in individual pocket packages.

Application of a composition for the treatment of surfaces to fibrous structures 1-3: Immediately after the operation of bonding sheets, the composition for surface treatment is printed on the surface of the fibrous structure of 4 sheets and / or product hygienic tissue paper using a rotogravure printing process. Approximately 1.5 g / m2 of the surface treatment composition is transferred to each side of the 4-leaf product. The printing station consists of two engraved anilox rolls facing in a horizontal distribution and forming a space therebetween, through which the fibrous structure and / or tissue paper hygienic product is passed. The geometry is distributed so that the rollers touch the fibrous structure and / or the tissue paper hygienic product and transfer the lotion composition macroscopically uniformly on both surfaces of the fibrous 4-leaf structure and / or the tissue product. but that the fibrous structure and / or tissue paper hygienic product does not wrap any of the two anilox rolls. The anilox rolls are recorded at a volume of cells of about 3 ml per square meter and about 100 cells per square centimeter, and are supplied with the lotion composition from a closed supply chamber designed to fill the volume etched with lotion. The space between the two rollers is adjusted to achieve the projected added level. The surface coverage of the composition for surface treatment was practically 100% and homogeneous. The surface coverage can be tested using a composition for surface treatment with 0.01% Tinopal CBS-X, a fluorescent dye, commercially available from Ciba Specialty Chemicals, Basel, Switzerland. Samples were also made using an identical application system for the application of the lotion composition as described below. The equipment was operated at room temperature at a disk speed of approximately 419 rad / s (4000 rpm). The surface coverage of this application is less than using a printing process as described above. Still within the scope of the invention, this method is not so preferred.

Application of the lotion composition to the fibrous structures of Examples 1-3: After the composition for surface treatment, the lotion composition is applied to the fibrous structure and / or to the tissue paper hygienic product. The stretch of fibrous structure and / or the tissue paper hygienic product between two operations was approximately 5 meters. For the present invention, a rotary spray application system RFT-Compact-III was modified with applicator heads for the textile and textile industry (available from Weitmann &Konrad GmbH &Co KG, Leinfelden Echterdingen, Germany). The application head is equipped with 5 sets of rotating discs (type 1/1) and has an effective application width of 448 mm. The upright or housing of the applicator head was replaced by water heated walls in the upper, lower and back sections of the applicator head. Then the whole unit was isolated to the outside. Two of these modified application heads were used, installed facing each other so as to be able to treat both sides of the fibrous structure and / or tissue paper hygienic product simultaneously. Heating units with an integrated pump (type W60 / 10-12 / 40, marketed by Kelviplast GmbH, Germany) are used to supply water to the application units at the desired temperature. In particular, the heating elements were designed in such a way that the internal temperature of the applicator head was + 1-2 ° C with respect to the desired temperature. The feed of the lotion composition of the applicator heads is connected through a heat transfer line to a heated pump which is connected through this heat transfer line to a heated tank of 100 liters which retains the lotion composition melted The return lines of the applicator are fed back into the heated tank. A heated flow meter was installed in the supply line of the lotion composition between the pump and the applicator heads. The flow meter (Promass 63M, available from Endress &Hauser, Switzerland) was connected to the control unit of the RFT-Compact-III system which was then used to control the lotion composition pump (gear pump of the type Labu Brox) to dispatch the desired lotion composition flow to the application heads. No changes were made to the configuration, shape and dimensions of the rotating surfaces of the commercially available applicator head. Each set of rotating surfaces was formed by 2 rotating discs stacked one on top of the other. The amount of lotion composition supplied to the two rotating surfaces of each stack was the same. The discs have a diameter of approximately 98 mm. The five individual stacks of rotating surfaces are spaced about 112 mm apart. The first, third and fifth set of rotating surfaces is installed vertically offset as opposed to the second and fourth stack of rotating surfaces, to avoid interference between horizontally superposed droplet streams. The rotating surface sets are marketed by Weitmann & Konrad GmbH & Co, Germany (of the type 1/1, Art No. 618996 Top grant) and 618997 [inferior suit]). The applicator is operated horizontally and with a distance of 154 mm between the fibrous structure and / or tissue paper hygienic product and the center of the discs. The fibrous structure and / or the tissue paper hygienic product is passed vertically from top to bottom between the two application heads. Controlled by the windows of the housing between the rotating surfaces and the fibrous structure and / or tissue paper hygienic product, each stack of rotating surfaces covers a width in the transverse direction of about 224 mm on the fibrous structure and / or sanitary tissue product a exception of the two outer stacks of the rotating surfaces of the applicator that only cover 112 mm each. The currents of two stacks of rotating surfaces overlap in each position. The even distribution of the individual piles of the discs was achieved with flow regulators of 1 mm in diameter, installed between the feeds of the rotating discs and the central feeding pipe of the applicator. The temperature of the lotion composition is controlled to a certain value by heating the tank, the line and bringing the temperature of the applicator heads to the desired value. The flow rate is adjusted to achieve the desired level of fibrous structure addition. During application, the fibrous structure and / or tissue paper hygienic product are generally maintained at room temperature. Some samples were taken where the fibrous structure was cooled or heated before applying it to the lotion composition. The lotion composition solidifies almost instantaneously after impacting the fibrous structure and / or tissue paper hygienic product. Samples are then taken with added levels of 1.5 g / m2, 2.3 g / m2, 3 g / m2 and 4.5 g / m2 per fibrous structure and / or tissue paper hygienic product. The coverage of the surface area of the lotion composition is approximately 15% for the sample made with 3 g / m2 of application of lotion per side of fibrous structure and / or tissue paper hygienic product, a disc speed of approximately 262 rad / s (2500 rpm), and a lotion composition temperature in the applicator of approximately 56 ° C.

Conditions the process for the treatment of fibrous structures of Examples 1-3: The rotating surfaces were operated at 262 rad / s (2500 rpm) for the samples described below, but samples were also made at speeds between 21 rad. / s (200 rpm) and 524 rad / s (5000 rpm). In general, the composition is maintained at a temperature of about 5-10 ° C above the melting temperature, for the lotion compositions described below, all temperature settings are maintained at 56 ° C. The products are processed at temperatures below 2 ° C below the melting point and more than 10 ° C above the melting point. The speed of the fibrous structure and / or tissue paper hygienic product for the following examples is 200 m / min, but it is possible to make samples at fibrous structure speeds and / or hygienic product of between 10 m / min and 400 m / min.

Test methods A. Coating test method of the surface area The local composition for surface treatment and / or the basis weight of the lotion composition on the surface of the fibrous structure can be determined by means of IR / NIR scanning spectroscopy (infrared or near infrared) in transmission mode (absorption spectroscopy) using a Perkin Elmer Spectrum Spotlight 300 instrument together with Spotlight software version 1.1.0 B38. The following procedure can be applied to the composition for surface treatment and / or to lotion compositions comprising a linear hydrocarbon component of repeating units of - (CH2). Maybe it's It requires an adaptation process if most or all of the composition is made up of other materials. Such adaptations will depend on the composition and will generally be apparent to experts in the industry. The measurements are made with representative samples for the tissue. A sample of 5 x 5 mm (or larger) is placed in the sample holder, which is mounted on an XY table and the spectral area used for the analysis is scanned at a spatial resolution of 25 μ? in both dimensions in x and y. For the analysis of materials containing linear chains of -CH2- groups, the region is scanned between 4000 cm-1 and 4500 cm-1 and the range between 4296 cm-1 (W1) and 4368 cm-1 (W2) is used. ) for the analysis. At least 16 scans are taken at a resolution of 1 cm-1. If 16 scans are used, it is necessary to ensure that the sample does not change its structure as a result of heating. Then a map of the local base weight of the sample is generated. The integrated absorption between W2 and W1 is determined above an ascending linear initial value for each pixel of 25 μ? T? x 25 pm using the ChemiMap menu of the program. The initial value is defined by the absorbance in W1 and W2. The option of two base points is selected in the ChemiMap menu of the software and is configured in W1 and W2. The start and end point of the integration are also configured in W1 and W2. The pulse reduction factor is set to a value V1 defined as: V1 = F * DW where F is the factor described below and DW = W2-W1 is the delta value in wave numbers between the upper wave number ( W2) and the lower one (W1) in cm. "The pulse reduction factor with the DW factor transforms the average absorbance above the initial value within a wave number range from W1 to W2 into an integrated absorption with a value greater than the initial value Factor F translates the integrated absorption in local basis weight in g / m2.

The file generated with the ChemiMap command, contains the local basis weight for each pixel of 25 pm x 25 pm in the area. This file is saved as a text file (txt format) and also as a bitmap (bmp format) in an 8-bit gray scale format. The text file is imported into EXCEL and the first row and the first column are deleted (they contain no image data but position data). The resulting data represent the distribution of the pixels of the local basis weight in g / m2. The maximum (MaxLBW) and minimum (MinLBW) and average (AvgLBW) values of all data sets are calculated in EXCEL. The bitmap file (bmp file) is imported into Analysis software for further analysis (Analysis Pro version 3.1 (construction 508), available from Soft Imaging GmbH, Germany). The file imported in gray scales continues in RGB format with the three channels configured in the same way (in 8-bit resolution). In the AnalySIS software the file is separated by colors to extract one of the three channels of identical colors (red). The resulting file is scaled from G = 0 to G = 255, G = 0 representing the minimum value (MinLBW) of the original concentrated light data and 255 representing the maximum value (MaxLBW) of the original concentrated light data. The image is calibrated in x-y and by configuring the size of the pixel in dimension x and y to adapt it to the original sample. The image is scaled in the z direction to show the local base weight values in g / m2 but all the calculations within AnalySIS should be done in the scale G = 0 to G = 255. The G values can easily be transformed into local basis weight numbers by means of the following relationship: LLBW = A * (G + COMPENSATED), where A = (MaxLBW-MinLBW) / 255 and COMPENSATED = (255 * MinLBW) / (MaxLBW-MinLBW) The G values can be easily transformed into base lot numbers of the local lotion (LLBW) by means of the following relationship: G = (LLBW / A) -COMPENSED The LLBW can be the basis weight of the local lotion composition or the weight base of the composition for the treatment of surfaces depending on what is being measured. The average value of all data points of the local basis weight above 10 g / m2 can be calculated from the EXCEL data file. The area of fibrous structure and / or tissue paper hygienic product affected by the composition is calculated in Analysis, establishing a lower threshold level at the G-value equivalent to 3 g / m2 and calculating the area above said threshold. The "unfilled holes" configuration is used. The areas of the composition are determined in a similar manner by configuring the threshold a G-value equivalent to 10 g / m2 (10 g / m2 equal to G = 10 / A -COMPENSED). If it is defined that the areas of the composition have a certain minimum or maximum, the area is established as a filter. The percentage of the area of the composition greater than a certain area is calculated by dividing the area of the composition calculated without the area filter by the area of the composition calculated with the filter. The factor F for converting the integrated absorption values into local absorption basis weight values is determined by the following procedure: A representative set of average basis weight calibration samples of the composition is scanned in the spectral range used for the analysis as described above and analyzed for peak areas integrated between W1 and W2 (4296 cm-1 and 4368 cm-1 mostly for hydrocarbon type materials). The integrated peak area is obtained from the previous procedure if the F factor is set equal to 1. Then, the data set is imported into EXCEL and the average pixel value of this data set is calculated. Since the factor F was set equal to 1, this value is equal to the average integrated peak area (AIPA) of the sample in the wave number range from W1 to W2. The factor F is then calculated as F = / slope of a less square linear assembly through the origin of the graphic representation of AIPA vs. the average basis weight of the composition of the sample. Calibration samples for determining factor F can be prepared or a sample containing an existing composition can be used. If an existing sample is used, the basis weight of the composition can be determined by extraction. An example for this procedure is given below. Below are some examples of how factor F is determined by analyzing an existing sample (market product) and preparing calibration samples. It is important that the absorbance in the interval of the wavelength used for analysis is never greater than 1 to ensure a linear correlation between the infrared signal and the basis weight of the local composition. i. Determination of factor F by preparing calibration samples Preparation of calibration samples: A suitable piece of substrate of known area, weight and basis weight is treated uniformly with the composition. A suitable equipment is a hot wax cartridge atomizer type MK-DUO Art. No. 140101, available from MK Heiftwachstechnik GmbH, Aichach, Germany. After application, the composition is balanced on the canvas by placing the sample in an oven at a temperature of about 10 ° C above mp (or at a suitable temperature to allow the composition to stabilize on or on the canvas). For relatively low viscosity samples it is sufficient to let them stabilize for one hour.

The sample is then cooled to room temperature and equilibrated to achieve a moisture content at 23 ° C) and 50% (+ -2%) relative humidity and reweighed. The basis weight of the composition of that sample [in g / m2] is calculated as (weight of the sample after the treatment of the composition [in grams] - weight of the sample before the treatment of the composition [in grams]) divided for the sample area [in m2]. The samples are then analyzed by the procedure described above to determine the factor F. Preferably, the calibration samples are prepared in a range of base weights of the composition that include the range to be measured. Determination of the F factor for a market product: The base weight of the sample is determined by means of a standard procedure. Then the sample is analyzed by means of the procedure described above for the integrated average peak area between 4296 cm-1 and 4368 cm-1. The sample is then extracted by the procedure described below to determine the additive level of the composition. Then the F factor is calculated as factor F = basis weight of the composition [g / m2] / average integrated peak area In case the composition does not contain a sufficient amount of linear hydrocarbon, or if the substrate contains material that does not allow to quantify the composition between 4296 cm-1 and 4368 cm-1, it is necessary to identify a range of different wave number in the range infrared or near infrared that is suitable for quantifying the composition by IR spectroscopy. It is possible to use any wave number range with a linear correlation between the integrated absorption coefficient above the initial values and the weight of the composition. In case of identifying more than one range of wave number, the range with the best signal-to-noise ratio will be used. When the composition is based on materials of the linear hydrocarbon type with CH2 groups, the absorption band should be used between 4296 cm-1 and 4368 cm-1.

B. Relative concentration of the composition in the surface test method The relative concentration of a composition on the surface of a fibrous structure and / or tissue paper hygienic product can be determined using IR spectroscopy, especially if the sample contains a composition containing hydrocarbon content. The IR spectroscopy method can use a filter photometer or other near infrared instrument, but must be configured to detect backscattering. Appropriate wavelengths are used. The fibrous structure and / or tissue paper hygienic product is placed under the near infrared instrument and the reading is obtained. Then the sample is turned to obtain a reading on the other side of it. In addition to near-infrared spectroscopy, medium infrared spectroscopy with suitable equipment and wavelengths can also be used to determine the relative concentration of a composition on a surface of a fibrous structure and / or tissue paper hygienic product.
