Description

Field of the Invention

The present invention relates to an absorbent paper tissue comprising an adhesive applied to at least a portion of a surface of the paper tissue. However, it should cover no more than 80% of said surface area that can be used to collect particles from a smooth surface, especially in, but not limited to, the domestic environment.

Prior art

The technical problem underlying the present invention is to provide an absorbent tissue with a better ability to collect particles from a smooth surface, but providing the advantages of known absorbent tissues, in particular in terms of liquid absorbency, said being tissue paper towels stored in roll form or stacked on top of each other.

Tissues of absorbent paper such as household towels commonly available today are very suitable for the removal of drops or small wet areas on smooth surfaces such as panels or tables. However, the collection of small solid particles such as sugar, bread crumbs or pieces of paper is almost impossible.

Unlike liquid substances, the absorption of solid particles in the absorbent tissue does not work. The only possibility of picking up the inside of the tissue is of mechanical type, in which the user tries to collect the particles using the tissue.

In the case of bread crumbs on the table, however, there is a considerable risk that the particles collected in the first instance will fall again. Sometimes, the desired effect is achieved using a damp tissue paper. However, there is no guarantee for this and the solution is not perfect in most cases. Some materials adhere to the tissue due to moisture, but the adhesive strength is often not enough.

Document DE-A 199 55 795 discloses an adhesive cleaning wipe comprising a water soluble sheet that develops an adhesive force when water is applied. However, this document does not disclose that an adhesive is applied on a surface of said cleaning wipe that covers no more than 80% of said surface area in order to allow the storage of said cleaning wipes in the form of a roll or stacking on each other. .

The US document A 3 981 741 refers to a fibrous cleaning material impregnated with a mixture of latex which, after the addition of water, develops an important capacity to absorb dirt on the surface. This document does not show that no more than 80% of the surface area of said cleaning material must be covered with an adhesive to allow storage of said cleaning material in the form of a roll or by stacking.

EP-B 829 222 discloses a network material comprising a binding agent, in which the network is made of a non-woven material and the binding agent is applied within the range of 100 to 200 g / m2.

However, in order to stack the cut net material, a separator material is required, which is placed between two studs to prevent adhesion between them.

Therefore, the consistency of the adhesive layer or bonding agent, respectively, is not suitable for use as absorbent tissue paper stacked on top of one another or, preferably, on rolls.

The US document A 5 198 292 also refers to a non-woven, knitted or knitted cleaning garment containing an adhesive and a bonding agent that are effective in removing dirt from a wide variety of surfaces. However, this document does not refer to absorbent paper tissues such as household wipes, which are stacked or preferably rolled up for storage, so that this document does not provide ideas on the amount or type of adhesive layer.

US-A-4 990 192 discloses absorbent paper towels on which discrete adherent globules are sprayed without forming a continuous coating on the surface. Alternatively, the garment may be used instead of a paper towel, while the facial or paper tissue is not desirable.

It is an object of the present invention to provide an absorbent tissue, especially absorbent household paper, capable of collecting small solid particles such as sugar, bread crumbs or pieces of paper.

It is another technical object of the present invention to allow said absorbent paper tissues capable of collecting small solid particles to be stored in roll form or stacked on top of each other.

Brief summary of the invention

The aforementioned technical objects are solved by an absorbent paper tissue comprising the features of claim 1. The embodiments are named in the dependent claims.

Detailed description of the invention

The term "absorbent paper tissue" refers to an absorbent paper tissue of one, two or three folds and also includes an absorbent paper tissue consisting of four, five, six or more folds folded together. Normally, said absorbent tissues are used as household, facial wipes, hand towels or toilet paper.

A tissue is defined as a soft absorbent paper that has a low base weight. Generally, a base weight of 8 to 40 g / m2, preferably 8 to 30 g / m2, especially 10 to 25 g / m2 per fold is chosen. The total base weight of the paper products is preferably equal to a maximum of 70 g / m2, more preferably to a maximum of 65 g / m2. Typically its density is below 0.6 g / m2, preferably below 0.30 g / cm3 and more preferably between 0.08 and 0.20 g / m3.

Chiffon paper production is distinguished from paper production by its low base weight value and its high tensile energy absorption rate (see DIN EN 12645-4 and DIN EN 12625-5). The paper and the paper handkerchief also differ in general with respect to the modulus of elasticity that characterizes the stress deformation properties of these flat products as a parameter of the material.

The high tensile energy absorption rate of the gauze paper comes from external or internal pleating. The first is produced by the compression of the paper net that adheres to the dry cylinder as a result of the action of the pleated shredder or in the latter case as a result of the speed difference ("pressure transfer") between the two belts endless ("fabrics"). This causes the network of plastically still wet deformable paper to break internally by compression and shear, thus resulting in a greater capacity for drawing under load than unfolded paper. Normally, most wet tissue paper nets are dried by the so-called Yankee drying, air-drying (TAD) or the impulse drying method.

Normally, the starting material for the production of the tissue is a fibrous cellulosic material, in particular paper pulp. However, if cotton or cotton eraser is used as a starting material for the production of tissue paper, normally no further steps of paper pulp reduction are required. Due to the morphological structure, cellulose already exists in the open state.

The paper pulps used may be related to major fibrous materials (raw paper pulp) or secondary fibrous materials, in which the secondary fibrous material is defined as a fibrous raw material coated from a recycling process. The main fibrous materials may be related to either a chemically digested paper pulp or a mechanical paper pulp such as the thermo-refiner mechanical paper pulp (TMP), the chemo-refiner mechanical paper pulp (CTMP) or the high temperature chemo-thermo-mechanical paper pulp (HTCTMP). Synthetic fibers containing cellulose can also be used. However, the use of paper pulp from plant material, in particular wood processing plants, is preferred. For example, fibers from softwood (usually originating from conifers), hardwood (usually originating from deciduous trees) or from cottonseed can be used. Also used as raw materials are esparto fibers (alpha), grass, bagasse (cereal straw, rice straw, bamboo, hemp), hemp fibers, flax and other sources of wood and cellulosic fibers. The corresponding fiber source is chosen according to the desired properties of the final products in a manner known in the art. For example, hardwood fibers, which are shorter than softwoods, give the final product greater stability according to the fiber diameter / length ratio. If it is intended to achieve softness in the product, which is important for example for paper tissues, eucalyptus wood is particularly suitable as a source of fiber.

With respect to the softness of the products, the use of paper pulps of chemical raw materials is also preferred, in which it is possible to use completely bleached, partially bleached or unbleached fibers. Paper pastes of suitable chemical raw materials according to the invention include, among others, sulphite paper pastes, kraft paper pastes (sulfate process).

It is also possible to use regenerated synthetic fibers or synthetic fibers such as polyolefin fibers, polyester fibers or polyamide fibers, as a starting material for the production of tissue paper, for example improving the strength, absorption, softness or lightness of the tissue. of paper. The tissue according to the

The invention may also comprise a small amount of nonwoven materials.

The fibers can be treated with additives - such as fillers, softeners, such as quaternary ammonium compounds and binders, such as conventional drying resistant agents or moisture resistant agents used to facilitate the manufacture of original paper or to adjust its properties.

The gauze paper manufacturing process basically comprise

a) forming that includes a header box and an endless belt part, b) the drying part (TAD (drying with air that passes through)) or conventional drying on a Yankee cylinder, which also includes the essential pleating process for gauze paper, c) typically the control and the winding area

The paper can be shaped by placing ("wet layering") the fibers, in an oriented or random manner, on one or between two continuous rotating endless belts of a papermaking machine while simultaneously remove the main amount of dilution water until a dry solids content is normally obtained between 12 and 35%.

Drying of the shaped main fibrous network takes place in one or more stages by mechanical and thermal means until the final solids content is normally about 93 to 97%. In the case of papermaking, this stage is followed by a pleating process that exerts a crucial influence on the properties of the finished tissue paper in conventional processes. Normally, the conventional dry pleating process involves pleating on a drying cylinder 4.5 to 6 m in diameter, the so-called Yankee cylinder, by means of a pleading shredder, with the final dry solids content mentioned above. tissue paper (wet pleated can be used if a lower quality demand is required for the gauze paper). Finally, the raw, dry and pleated tissue paper (raw gauze paper) is available for further processing to give rise to the paper product or the paper tissue product according to the invention.

Instead of the previous conventional process of manufacturing the gauze paper, the invention also relates to the use of a modified technique in which an improvement of the specific volume is achieved by means of a special type of drying with process section b) and of This mode achieves an improvement in the gross softness of the tissue paper manufactured in this way. This process, which exists in a variety of subtypes, is called the TAD technique (air dried through it). It is characterized by the fact that the “main” fiber network (such as non-woven material) leaving the sheet manufacturing stage is pre-dried until a dry solids content of approximately 80% is obtained, before Final drying by contact with the Yankee cylinder by blowing hot air through the fiber network. The fiber network is supported by an endless air-permeable belt or conveyor belt and, during transport, is guided on the surface of an air-permeable rotary cylindrical drum. The structuring of the endless conveyor belt or the conveyor belt makes it possible to produce any pattern of areas under compression broken by deformation in the wet state, resulting in higher values of specific mean volume and therefore resulting in gross smoothness without diminishing important resistance of the fiber network.

Another possible influence on the softness and strength of the raw gauze paper is based on the production of the formation of layers that make up the main fiber network, by a header box specially constructed for the purpose, in the form of different physical layers of fibrous material, these layers being supplied together in the form of a strand of paper pulp in the manufacturing stage of the sheet. When the processing of the raw fibrous web or the raw paper tissue to give rise to the final product ("conversion"), the following process steps are usually used individually or in combination: size cut (longitudinal cut and / or transverse), production of a plurality of folds, mechanical (embossed, striated) and / or chemical (adhesive) production of crease adhesion, volumetric and structural embossing, folding, printing, drilling, application of lotions, smoothing, stacking rolled up

To produce multi-fold paper tissue products, such as handkerchiefs, toilet paper, facial or household wipes, an intermediate stage called dubbing preferably takes place in which the desired number of folds is normally conferred to the gauze paper Gross of the finished product using a common multi-fold master roller.

The processing stage of the raw tissue paper that has already been optionally rolled in several folds to give rise to the finished product takes place in the processing machines that include operations such as repeated smoothing of the gauze paper, edge embossing, up to one end combined with the complete area and / or local application of adhesive to produce the adhesion of the fold of the individual folds (raw gauze paper) object of combination, as well as the longitudinal cutting, folding, transverse cutting, placement and assembly of the plurality of tissue papers and their packaging as well as their meeting to form large packages or packages. Individual networks of paper folds can also be pre-embossed and subsequently combined in a roller recess according to nested foot-foot methods.

The present invention can also be used for all types of tissue products known in the art, such as handkerchiefs, facial wipes, toilet paper, household wipes or napkins, although domestic wipes and napkins are preferably used.

In accordance with the present invention, the absorbent tissue paper contains an adhesive applied to at least a part of its surface. Said adhesive should be non-toxic.

There are several qualities available including KratonTM G-1726, KratonTM G-1650, KratonTM G-1651, KratonTM G-1652, KratonTM G-1657, all of them saturated diblock mixtures AB / ABA triblock with middle ethylene / butylene blocks; KratonTM D-1112 a high percentage of linear styrene-isoprene-styrene diblock polymer A-B; KratonTM D-1107 and KratonTM D-1111, mainly linear block copolymers of styrene-isoprene-styrene triblock A-B-A; KratonTM D4433X, a linear "SIS" styrene-isoprene-styrene block copolymer with an oil content of 30% by weight and KratonTM D1184, a high molecular weight "SBS" block copolymer of styrene-butadienestirene, both available in Shell Chemical Co .; StereonTM 840ª and StereonTM 841ª, multi-block SBS block copolymers A-B-A-B-A-B available at Firestone; EuropreneTM Sol T-193-B, a linear SIS block copolymer available from Enichem Elastomers; EuropreneTM Sol T-190, a linear styrene-isoprene-styrene block copolymer and EuropreneTM Sol T-163, a radial SBS block copolymer both available from Enichem Elastomers; VectorTM 4461-D, a linear SBS block copolymer available from Exxon Chemical Co .; VectorTM 4111, 4211 and 4411, fully coupled linear SIS block copolymers containing different percentages of styrene terminal block; and VectorTM 4113, a highly coupled SIS block copolymer also available from Exxon Chemical Co .; and the DPX-550, DPX-551 and DPX-552 radial SIS block copolymers available from Dexco Polymers. This listing is not exclusive and there are numerous qualities of block copolymers available from various sources of such adhesives, especially called hot melt adhesives. These polymers can be used alone, in any combination.

Other adhesive polymers include a considerably linear copolymer having the general AB-A configuration, in which block A can be polystyrene and block B can be ethylene-butylene, ethylene-propylene, isoprene, butadiene or mixtures thereof, and preferably Block B is ethylene-butylene or ethylene-propylene. Adhesive polymers of this type, such as KratonTM G-from Shell Chemical Co., of Elf Atochem North America under the trade name LotryTM including 35 BA 900 and 35 BA 1000; from Exxon Chemical Co., under the trade name of EscoreneTM that includes XW-23.AH and XW-22.

Other suitable adhesive polymers are based on polymers having units derived from vinylamine compounds.

Other compounds that can be used as adhesives are conventional water soluble and dispersible adhesive components such as glutin, casein, starch (also in modified form), dextrin or mixtures thereof. Appropriate adhesives can also be formulated with so-called synthetic resins. Such resins include, among other materials, (a) natural and modified resins, (b) polyterpene resins, (c) phenolic modified hydrocarbon resins, (d) coumarone-indene resins, (e) aliphatic and aromatic hydrocarbon resins petroleum, (f) phthalate esters and (g) hydrogenated hydrocarbons, hydrogenated rosins and hydrogenated rosin esters.

In the case where the adhesive is applied on the surface by initiating the penetration of said adhesive from an inner layer through an external fold towards the surface of said external fold, under the influence of a mechanical force, it is preferable to use a pressure sensitive adhesive.

In a preferred embodiment, the pressure sensitive adhesive comprises an adhesive polymer that is an acrylic adhesive polymer that is chosen from a wide variety of polymer and copolymers from acrylic and / or methacrylic acid or its ester, amide and nitrile derivatives. . Mixtures of different polymers and copolymers can be used.

Preferably, these polymers and copolymers have a glass transition temperature (Tg) of less than about 0, so that the polymer mass is sticky at room temperature.

Examples of useful acrylate-based adhesive polymers include hompolymers and copolymers comprising isooctyl acrylate, 2-ethylhexyl acrylate, isoamyl acrylate, nonyl acrylate and butyl acrylate and their copolymers and terpolymers with acrylic acid, methacrylic acid, acrylamide, methacrylamide, acrylonitrile and methacrylonitrile. It is also possible to incorporate non-polar acrylic monomers whose homopolymers have relatively high Tg values such as, for example, isobornyl acrylate (see, for example, WO 95 / 13,331 and WO 95 / 13,328).

Appropriate pressure sensitive adhesives may optionally be formulated with synthetic resins in order to improve adhesion and introduce tackiness in the pressure sensitive adhesive, to achieve the desired adhesive characteristics herein.

In accordance with the present invention, the adhesive is applied on at least a portion of a surface of the absorbent tissue paper. However, the adhesive covers not more than 80%, especially not more than 70%, preferably not more than 60%, more preferably not more than 50% of said surface to allow storage of said roll-shaped absorbent tissue or by stacking.

Such adhesives can be applied to the absorbent tissue paper for example as the so-called "hot melt", in which the adhesive is heated to its melting temperature or as an aqueous dispersion. Appropriate aqueous dispersions comprise among other adhesives, surfactants, emulsifiers, humectants, stabilizers and other chemical agents.

The adhesive to be applied on the surface of the absorbent paper tissue is used in an amount of up to 150 g / m2, especially in an amount of up to 120 g / m2, preferably in an amount of up to 100 g / m2 and more preferably in a amount of up to 80 g / m2.

In general, it is possible to apply the adhesive to the surface of the tissue at any time and at any point during or after the manufacture of said tissue.

However, it is clearly preferred to apply the adhesive after drying (and pleating) on the Yankee cylinder of the paper machine. In this way, the application can take place during the folding process of the single nets of the tissue in multiple networks, as a process stage in the conversion machine, or as an extra stage between dubbing and conversion.

The adhesive can be applied on the surface of the paper tissue either by spraying or by coating, in which the term coating also includes applying one or a few tapes that are coated with adhesives.

However, it is also possible to use printing techniques such as a rotogravure printing technique or a flexographic printing technique to apply the adhesive to the tissue.

In the case of using the spray technique, the adhesive is either heated to the melting point so that it is transferred into the so-called "hot melt" or applied as an aqueous solution. Although it is possible to apply the adhesive during the manufacture of the paper tissue, it is preferable that the paper tissue just be treated with the adhesive. The supply of adhesive to the product by means of a spraying device must be adjusted to the flow rate of the product to ensure that the selected amount of adhesive is applied to the chosen part of the tissue. This can be achieved, for example, by using a photo-ocular detection of a specific area of the paper tissue in which a signal is transferred, in a certain line, to the spraying device thereby initiating the supply of a certain amount of adhesive. The application of the adhesive on the paper tissue can also be achieved by coating during or after the manufacture of said paper tissue using an offset roller system. It is clearly preferred that the application of the adhesive by means of an offset roller system should be carried out after the manufacture of the tissue. In order to ensure that the chosen amount of adhesive is placed in the desired area of the tissue, a photo-ocular detection system that controls the drive of the offset rollers should be used.

In accordance with the present invention, it is possible for the adhesive to be applied over a limited surface area of the tissue, in which one part of said surface would be free of any adhesive, the other part would be covered by the adhesive and both parts they would be separated from each other by a line. In order to ensure that the user can easily remove said tissue from the soft area, the surface covered with the adhesive must comprise not more than 80%, especially not more than 70%, preferably not more than 60% and more preferably no more than 50% of the total surface area.

Instead of applying the adhesive to the limited surface area of the paper tissue, the adhesive can also be applied in the form of discrete dots covering a surface of said paper tissue. The term "discrete" means that each adhesive point should be clearly distinguishable from the other points, even though overlap with other adhesive points may occur.

Preferably, all adhesive points, if taken together, should cover no more than 80%, especially no more than 60% and more preferably no more than 50% of the entire surface area of an external fold. Such adhesive points may be present on the surface in the form of a trellis or may form an irregular pattern. Preferably, the individual adhesive has an area of 0.01 to 30 mm2, more preferably 0.02 to 15 mm2, even more preferably 0.02 to 10 mm2, in particular 0.02 to 6 mm2.

A process for manufacturing said paper tissue comprises the step of applying an adhesive on at least a part of a surface of the absorbent paper tissue. Said process is characterized by the fact that no more than 80% of said surface area is covered with the adhesive and that the adhesive is applied to the surface either by spraying or by coating or by means of printing, during or after the manufacture of said absorbent tissue paper.

It is important that the adhesive used is sufficiently tacky to allow the collection of large crumbs when the tissue is passed over the smooth surface. However, the strength of the adhesive should not be too great for the user to easily remove the tissue from the smooth surface and that the tissue can be stored in a roll or stacked form, one on top of the other, and then separated for use

The absorbent tissue according to the present invention is especially useful for collecting solid particles such as sugar, bread crumbs, pieces of paper or other solid waste.

The collection of solid particles is now possible without adversely affecting the ability of the tissue to absorb liquid substances. Furthermore, due to the fact that only one surface of the tissue is covered with the adhesives, the other non-sticky surface can still be used for subsequent cleaning once the solid particles have been collected. The present invention is a very interesting alternative to vacuum cleaners for tables and brushes, making the shaking of the tablecloth unnecessary and thus helps to facilitate domestic work.

The improved tissue paper developed in accordance with the present invention can be used, among others, as handkerchiefs, napkins, facial or hygienic tissue. However, there is a clear preference that these tissues are especially useful as household wipes.
