Definitions

  • the present invention relates to paper tissue products, and in particular to facial tissue, and disposable handkerchiefs. More particularly, the invention relates to a lotioned paper tissue product comprising a paper tissue substrate of improved quality.
  • Paper webs or sheets sometimes called tissue or paper tissue webs or sheets, and products made therefrom, such as paper handkerchiefs, sometimes also called facial tissues, find extensive use in modern society.
  • Such items as facial and toilet tissues and kitchen towels are staple items of commerce, all of which are herein referred to as paper tissue products. It has long been recognised that important physical attributes of these products are their strength and thickness/calliper, their softness and smoothness, their absorbency, and their lint resistance. Research and development efforts have been directed to the improvement of each of these attributes without seriously affecting the others as well as to the improvement of two or three attributes simultaneously.
  • Softness and smoothness relate to the tactile sensation perceived by the consumer when holding a particular product, rubbing it across the skin, or crumpling it within the hands.
  • the tactile sensation is a combination of several physical properties.
  • the tactile sensation can be well captured by the objective parameter of the physiological surface smoothness (PSS) parameter as known e.g. from US 5,855,738 .
  • PSS physiological surface smoothness
  • As important for the tactile sensation of consumers is the thickness/calliper of a tissue product.
  • Strength is the ability of the product to maintain physical integrity and to resist tearing, bursting, and shredding under use conditions.
  • Absorbency is the measure of the ability of a product to absorb quantities of liquid, particularly aqueous solutions or dispersions. Overall absorbency as perceived by the consumer is generally considered to be a combination of the total quantity of a liquid a given mass of paper tissue will absorb at saturation as well as the rate at which the mass absorbs the liquid.
  • Lint resistance is the ability of the fibrous product, and its constituent webs, to bind together under use conditions, including when wet. In other words, the higher the lint resistance is, the lower the propensity of the web to lint will be.
  • Products with high wet burst strength and typically a relatively high calliper are those produced by through-air-drying.
  • -air-drying facilities are not available on conventional paper making machines and the provision of such equipment means a considerable financial investment.
  • -air-drying facilities have an increased energy consumption as compared to more conventional drying facilities. Therefore it is still of interest to provide superior paper qualities employing conventional paper machines.
  • WO 98/58124 published on 23 rd December 1998, discloses an embossing method wherein embossing elements of a height of at least 1 mm are employed.
  • EP 0 408 248, published 16th January 1991 discloses a converting method wherein an embossing step is combined with a simultaneous calendering step.
  • EP 0 668 152 published 23 rd December 1998, discloses an embossing method employed unmatched male and female embossing elements with at least 15 discrete embossing elements per square cm.
  • EP 0 696 334 published on 10 th March 1999, discloses an embossing step with avoids an increase in bulk.
  • US 702 571 discloses tissue sheets with fine scale embossing patterns that contain at least 15 embossing per square cm.
  • US 5,855,738 discloses a process for making smooth paper tissue comprising a calendering step.
  • US 5 525 345 discloses a lotion for imparting a soft, lubricious feel.
  • the patent includes a description of some of the detrimental effects of mineral oils, which are commonly used in the art to impart a soothing feel.
  • One important such detrimental effect is that mineral oil easily migrates and may transfer for example to the packaging or wrapper material of the tissue product and soil these materials, so that there is a need to use special wrapper or packaging materials, such as expensive barrier materials.
  • the patent discloses an lotion composition comprising up to 80% of immobilizing agents.
  • WO 96/19204 describes a medicated lotioned tissue paper.
  • EP 0 808 157 granted 9 th June 1999, discloses a medicated tissue paper product comprising a lotion having both solid and liquid components.
  • the patent is concerned with economic lotion delivery, achievable by an improved lotion composition.
  • the present invention attempts to alleviate the detrimental effects of highly transferable lotions by providing a paper quality and structure particularly suitable for lotioned tissue paper, which still can be produced in a very economic fashion.
  • the present invention relates to a paper tissue, and in particular to facial tissue, and disposable handkerchiefs. Claimed and described is a method for making a tissue paper product from a tissue paper web, the method comprising the steps of:
  • a cellulosic fibrous structure is wet-laid using principles and machinery well-known in the art of paper-making.
  • a suitable pulp furnish for the process of making the paper tissue substrate preferably contains papermaking fibres consisting essentially of cellulose fibres (commonly-known as wood pulp fibres) or cellulose-derived fibres (including, for example, rayon, viscose). Fibres derived from soft woods (gymnosperms or coniferous trees) and hard woods (angiosperms or deciduous trees) are contemplated for use in this invention. The particular species of tree from which the fibres are derived is immaterial.
  • the wood pulp fibers can be produced from the native wood by any convenient pulping process.
  • Chemical processes such as sulfite, sulphate (including the Kraft) and soda processes are suitable.
  • Mechanical processes such as thermochemical (or Asplund) processes are also suitable.
  • thermochemical (or Asplund) processes are also suitable.
  • the various semi-chemical and chemi-mechanical processes can be used. Bleached as well as unbleached fibres are contemplated for use. Preferably no non-cellusotic fibres, such as latex, fibres are used.
  • the paper tissue according to the present invention may contain, as a highly preferred component a wet strength chemical agent.
  • a wet strength chemical agent Preferably up to about 3.0%, preferably at least 0.5%, and more preferably at least 0.8% by weight, on a dry fibre weight basis, of wet strength chemical agent, such as water-soluble permanent and temporary wet strength resin, are contained.
  • Wet strength resins useful herein can be of several types. For example, Westfelt described a number of such materials and discussed their chemistry in Cellulose Chemistry and Technology, Volume 13, at pages 813-825 (1979 ).
  • the wet strength resins are water-soluble, cationic materials. That is to say, the resins are water-soluble at the time they are added to the papermaking furnish. It is quite possible, and even to be expected, that subsequent events such as cross-linking will render the resins insoluble in water. Further some resins are soluble only under specific conditions, such as over a limited pH range. Wet strength resins are generally believed to undergo a cross-linking or other curing reactions after they have been deposited on, within, or among the papermaking fibres. Cross-linking or curing does not normally occur so long as substantial amounts of water are present.
  • Base-activated polyamide-epichlorohydrin resins useful in the present invention are sold under the Santo Res trademark, such as Santo Re 31, by Monsanto Company of St. Louis, Missouri. These types of materials are generally described in US-A-3 855 158 issued to Petrovich on December 17 th 1974; US-A-3 899 388 issued to Petrovich on August 12 th 1975; US-A-4 129 528 issued to Petrovich on December 12 1978; US-A-4 147 586 issued to Petrovich on April 3 rd 1979; and US-A-4 222 921 issued to Van Eenam on September 16 th 1980.
  • water-soluble cationic resins useful hererin are the polyacrylamide resins such as those sold under the Parez trademark, such as Parez 631NC, by American Cyanamid Company of Sandford, Connecticut. These materials are generally described in US-A-3 556 932 issued to Coscia et al on January 19 th 1971; and US-A3 556 933 issued to Williams et al on January 19 th 1971.
  • water-soluble resins useful in the present invention include acrylic emulsions and anionic styrene-butadiene latexes. Numerous examples of these types of resins are provided in US-A3 844 880 . Meisel Jr et al, issued October 29 th 1974. Still other water-soluble cationic resins finding utility in this invention are the urea formaldehyde and melamine formaldehyde resins. These polyfunctional, reactive polymers have molecular weights on the order of a few thousand. The more common functional groups include nitrogen containing groups such as amino groups and methylol groups attached to the nitrogen. Although less preferred, polyethylenimine type resins find utility in the present invention.
  • Temporary wet strength agents such as modified starch may also, optionally, be used. Combinations of permanent and temporary wet strength agents may be used.
  • the present invention may contain dry strength chemical agents, preferably at levels up to 3% by weight, more preferably at least 0.1% by weight, on a dry fiber weight basis.
  • a highly preferred dry strength chemical agent is carboxymethyl cellulose.
  • suitable dry strength chemical agents include polyacrylamide (such as combinations of CyproTM 514 and AccostrengthTM 711 produced by American Cyanamid of Wayne, N.J.); starch (such as corn starch or potato starch); polyvinyl alcohol (such as AirvolTM 540 produced by Air Products Inc. of Allentown, PA); guar or locust bean gums; and polyacrylate latexes.
  • Suitable starch materials may also include modified cationic starches such as those modified to have nitrogen containing groups such as amino groups and methylol groups attached to nitrogen, available from National Starch and Chemical Company (Bridgewater, NJ).
  • Chemical softening compositions comprising chemical debonding agents are optional components of the present invention.
  • US-A-3 821 068, issued June 28th, 1974 teaches that chemical debonding agents can be used to reduce the stiffness, and thus enhance the softness, of a paper tissue web.
  • US-A-3 554 862 issued on January 12 th 1971 discloses suitable chemical debonding agents. These chemical debonding agents include quaternary ammonium salts.
  • Preferred chemical softening compositions comprise from about 0.01% to about 3.0% of a quaternary ammonium compound, preferably a biodegradable quaternary ammonium compound; and from about 0.01% to about 3.0% of a polyhydroxy compound; preferably selected from the group consisting of glycerol, sorbitols, polyglycerols having an average molecular weight of from about 150 to about 800 and polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to 4000.
  • the weight ratio of the quaternary ammonium compound to the polyhydroxy compound ranges from about 1.0:0.1 to 0.1:1.0.
  • the chemical softening composition is more effective when the polyhydroxy compound and the quaternary ammonium compound are first premixed together, preferably at a temperature of at least 40°C, before being added to the papermaking furnish.
  • chemical softening compositions may be applied to the substantially dry paper tissue web, for example by means of a printing process (N.B. all percentages herein are by weight of dry fibres, unless otherwise specified).
  • Examples of quaternary ammonium compounds suitable for use in the present invention include either unmodified, or mono- or di-ester variations of: well-known dialkyldimethylammonium salts and alkyltrimethyl ammonium salts. Examples include the di-ester variations of di(hydrogenated tallow)dimethyl ammonium methylsulphate and di-ester variations of di(hydrogenated tallow)dimethyl ammonium chloride. Without wishing to be bound by theory, it is believed that the ester moity(ies) lends biodegradability to these compounds. Commercially available materials are available from Witco Chemical Company Inc. of Dublin, Ohio, under the tradename "Rewoquat V3512". Details of analytical and testing procedures are given in WO95/11343 , published on 27 th April, 1995.
  • polyhydroxy compounds useful in the present invention include polyoxyethylene glycols having a weight average molecular weight of from about 200 to about 600, especially preferred is "PEG-400".
  • paper tissue webs useful for the present invention may be made by any common method well-known to the person skilled in the art.
  • Such papermaking processes comrprise the dewatering of suitable pulp using, for example, one or more papermakers felts and/or belts.
  • conventional papermaking processes are preferred. Any process referred to herein as conventional is a papermaking process that does not comprise a step of through-air-drying. Alternatively, papermaking processes comprising a through-air-drying step can be utilised.
  • the present invention is specifically concerned with steps known in the art as converting steps.
  • One important converting step to be carried out in accordance with the present invention is an embossing step in which a very fine pattern is embossed using a low pressure.
  • Embossing of a paper tissue web is generally achieved by passing the web through the nip formed between two embossing rolls, at least one embossing roll comprising embossing elements.
  • An embossing roll typically comprises a curved, but otherwise flat surface.
  • Embossing elements are protrusions raising above this surface and having a certain height as measured in a direction perpendicular to the axis of the embossing roll from the curved flat roll surface to the utmost point of the protrusion.
  • Embossing elements have a certain width, to be measured in the plane of the essentially flat roll surface.
  • the term width as used herein refers to the diameter of a round embossing element measured the plane specified above (ie. at the bottom of the embossing element) or to the largest width measured in said plane, when the embossing element is not round.
  • the embossing elements can have any shape, such as pyramidal or half spherical, and the cross section of the embossing elements can be circular, oval or square.
  • the embossing elements may form a continuous pattern, but preferably are distinct form each other.
  • the embossing elements are disposed over at least one embossing roll in a very fine pattern, comprising at least 30 embossing elements, preferably at least 50, more preferably at least 60, yet more preferably at least 70, most preferably at least 80 embossing elements per square centimetre surface area of the embossing roll.
  • the embossing elements are not high, preferably they have a height of less than 1 mm, more preferably less than 0.8 mm, yet more preferably less than 0.6 mm, yet even more preferably less than 0.5 mm or less than 0.4 mm, and most preferably less than 0.3 mm.
  • the stretch embossing provides a ratio of embossed areas to unembossed areas from 5% - 95%, more preferably 20% to 80% and most preferably 40% - 60%, i.e. for the most preferred case 40% - 60% of the total surface area of the tissue paper web are embossed.
  • embossing roll Any known type of embossing roll and mode of operation of such roll is within the scope of the present invention.
  • two hard metal, eg. steel, embossing rolls are used, wherein a first roll comprises protruding embossing elements, referred to as the male roll, and a second roll comprises matching recesses, referred to a the female roll.
  • the recesses may be mirror images of the protruding embossing elements or may be adapted to be slightly smaller than exact mirror images, eg. due to a slight difference in size or shape (eg. slope) of those recesses in the female roll.
  • a first embossing roll comprises a web contacting surface provided from a hard metal comprising protruding embossing elements and a second roll comprises a web contacting surface comprising a softer material, eg. rubber, preferably a material of Shore A hardness 40-70, in which recesses are formed upon sufficiently close contact with the protruding embossing elements.
  • the size of the nip formed between the two embossing rolls is to be adapted depending eg. on the tissue paper web to be processed and depending on the embossing pattern used. Also depending on those considerations no pressure or some pressure may be applied to urge the first embossing roll and the second embossing roll together.
  • the rolls When two hard metal rolls are employed in the process, a male and a female role, the rolls should be operated so as to leave a space corresponding to 60% to 140%, preferably 80% - 120% of the calliper of the unembossed tissue paper between the protruding embossing elements of the male role and the bottom of the recesses of the female role.
  • the rolls When a hard metal roll is used in combination with a rubber roll, the rolls should be pressed against each other with a pressure of 10 N/square centimetre to 1000 N/square centimetre, preferably 20 N/square centimetre to 200 N/square centimetre and most preferably 50 N/square centimetre to 100 N/square centimetre.
  • embossing rolls are not heated and run at the same speed, but in alternative modes of operation at least one roll may be heated and the rolls may run at unequal speed.
  • embossing with a fine pattern serves to increase the calliper, or in other words the bulk of the paper tissue web. Therefore, in a highly preferred mode of the present invention a single web or a single ply of paper tissue is passed through the embossing nip. In alternative modes of operation a multitude of plies of paper may be passed through the nib at the same time.
  • the applicant believes that the deformation embossing described herein achieved a stretching of the tissue paper, leading to deformation, but not to any substantial densification of the tissue paper and hence the applicant does not consider the above described embossing method highly suitable for the joining of juxtaposed plies. It is rather contemplated to employ a separate and distinct joining step as to provide a multiply tissue paper product, the joining step preferably comprising an embossing step, such as "attachment embossing" described hereinafter.
  • a lotion is applied to the tissue paper.
  • the lotion may be applied by any suitable means, such as printing or spraying.
  • the lotion can either be applied to the paper web or a paper tissue product, either to the whole surface of the web or product or only to a portion thereof.
  • the lotion may be applied to all plies or only selected plies and to only one or to both surfaces of the plies. In one preferred embodiment lotion is applied to both outer surfaces of the paper tissue product.
  • a lotion has been found to contribute to the smoothness of the paper tissue, and hence decrease its PSS parameter. Moreover, the lotion has skin care benefits.
  • the lotion may comprise softening/debonding agents, emollients, immobilizing agents and mixtures thereof.
  • Suitable softening/debonding agents include quaternary ammonium compounds, polysiloxanes, and mixtures thereof.
  • Suitable emollients include propylene glycol, glycerine, triethylene glycol, spermaceti or other waxes, petrolatum, fatty acids, fatty alcohols and fatty alcohol ethers having from 12 to 28 carbon atoms in their fatty acid chain, mineral oil, namely silicone oil e.g. dimethicone and isopropyl palmitate, and mixtures thereof.
  • Suitable immobilizing agents include ceresin, stearyl alcohol and paraffins, polyhydroxy fatty acid esters, polyhydroxy fatty acid amides, and mixtures thereof.
  • lotion components include perfumes, antibacterial actives, antiviral actives, disinfectants, pharmaceutical actives, film formers, deodorants, opacifiers, astringents, solvents and the like.
  • lotion components include camphor, thymol, menthol, camomile extract, aloe vera, calendula officinalis.
  • transferable lotions are to be applied, most preferably comprising the components listed above, as transferability ensures superior skin care and pharmaceutical benefits.
  • the skilled person is aware how the listed components influence the transferability of the lotion, the amount of mineral oil comprised of course being a critical parameter.
  • transferable lotion refers to any lotion, which achieves a transfer rate of more than 0.25 % according to the stationary lotion transfer test on unembossed paper described herein.
  • Preferred transferable lotions achieve a transfer rate of more than 0.5%, more preferably more than 1%, 2% or 5% according to the stationary lotion transfer test on unembossed paper described herein.
  • the level of transferability can be relatively high to optimally achieve the benefits associated with the lotion, as most of the disadvantages hitherto associated with the use of high amounts of a highly transferable lotion are overcome by the present invention.
  • the data obtained by the lotion transfer test described hereinafter confirm some of the beneficial effects of products made in accordance with the present invention.
  • the product, which was stretch embossed in accordance with the present invention delivers a very low amount of lotion when is stationary contact with a surface, but delivers a much higher amount of lotion when rubbed over a surface.
  • Stationary contact with a surface is representative of the contact of a tissue paper product with the packaging material when the product is packaged.
  • a low lotion transfer rate avoids the need for expensive packaging material.
  • Stationary contact with a surface is further representative of the contact of a tissue paper product with the fingertips of a user when taking such a tissue paper product out of the package and preparing to use it eg. in the nasal area. While the beneficial effects of a lotion will typically be desired in the nasal area, transfer of the lotion to the fingertips of a user is typically undesired and experienced as an unwanted feeling of greasiness, which may even trigger a need to wash one's hands.
  • Rubbing over a surface is representative of the usage of a lotioned tissue paper product in the target area, which most often is the nasal area. A slight rubbing movement in the nasal area is a frequently encountered usage habit, which of course can be enhanced by providing users with appropriate usage instructions.
  • the product that was stretch embossed in accordance with the present invention delivers considerably less lotion when in stationary contact with a surface than the stretch embossed product.
  • the lotion delivery upon a rubbing action is no worse than for an unembossed tissue paper product.
  • Preferred tissue paper products according the present invention will achieve a lotion transfer upon rubbing which is at least 1.1 times, preferably 1.5 times, more preferably 2 times, 5 times or 7 times and most preferably at least 8 times as high as the stationary lotion transfer measured in accordance with the test procedures described hereinafter.
  • the method for making a tissue paper product according to the present invention may comprise a number of further optional steps:
  • any known method of calendering can be employed in the converting process, however, in accordance with the present invention unusually high calendering pressures are used.
  • the calendering step is carried out after the stretch embossing and before the lotion application.
  • a calendering step in accordance with the present invention comprises passing one or several tissue paper webs through a calendering nip formed between a first and a second calendering roll.
  • both calendering rolls contact the web over a certain length, herein referred to a contact length, measured parallel to the direction of the axis of said first calendering roll.
  • the calendering rolls exert a pressure onto the web of at least 30 N per centimetre of said contact length and in order to do so will be pressed against each other with such a pressure. More preferably the pressure per centimetre of said contact length is from 50 N to 300 N, more preferably 60 N to 250 N, yet more preferably 70 N to 200 N and most preferably 120 N to 150 N.
  • the paper tissue webs are calendered as the paper tissue product will comprise plies, for example two, three or four webs can be juxtaposed and calendered in one step.
  • calendering rolls are not heated and run at the same speed, but in alternative modes of operation at least one roll may be heated and the rolls may run at unequal speed.
  • Calendering is well known in the art to reduce the calliper of a tissue paper web, and typically employed to ensure the calliper of the paper tissue product meets the required specifications.
  • Calendering is known to reduce the perceived softness of a paper tissue product. Calendering is therefore, at least in the area of hygiene papers, such a paper handkerchiefs, carried out at not too high pressures, typically for an embossed paper web 10 N/cm to 20 N/cm are selected.
  • the paper tissue web after undergoing a stretch embossing step and a calendering step is of increased calliper as compared to the untreated web.
  • the comparison is to be made between three layers of untreated web versus three layers of embossed and calendered web.
  • a calendering with a high pressure is known to reduce the calliper of a paper web considerably, as for example stated in German patent application DE O 44 14 238.2 .
  • the method claimed in the present invention has been found to increase the calliper of a paper tissue web by 10%, sometimes even 30% and even up to 40%, 60%, 80% or 100% when comparing the calliper of the untreated web with the calliper of the treated web.
  • the stretch embossing step alone achieves calliper increases of typically 50% to 200%.
  • a paper tissue according to the present invention has a first and a second surface, the surfaces being mutually opposed to each other, and a thickness orthogonal to the first and second surface.
  • the thickness is also referred to a calliper of the tissue.
  • the calliper of a 3-ply paper tissue product according to the present invention is preferably from 0.1 mm to1 mm, more preferably from 0.2 mm to 0.5 mm.

  • Juxtaposed plies of the paper tissue web may be joined as to provide a multi ply paper tissue product, preferably by attachment embossing.
  • attachment embosssing refers to an embossing by which all plies of a multiply tissue according to the present invention are embossed in one process step.
  • the attachment embossing does not or at least not to a large extent affect the smoothness of any calendered ply. Therefore, preferably the tissue has an unembossed surface over a major part of the surface area of the tissue, preferably on the first and the second surface.
  • the tissue has one or more regions not comprising an attachment embossing and, optionally, one or more regions comprising an attachment embossing, and that the region not comprising an attachment embossing is at least 50%, preferably at least 80% and in some preferred embodiments as much as 99%, of the surface area of the tissue.
  • the regions comprising an attachment embossing lie close to the edge of the tissue (for example along two or four edges); and a regions comprising an attachment embossing may also be used for decorative purposes (for example to create a pattern or to spell out a logo or brand name).
  • the region not comprising an attachment embossing is the continuous region between and/or around the region comprising an attachment embossing.
  • Attachment embossing is preferably done by steel-to-steel pin-to-pin embossing and with 10 to 40 embossing elements per square centimetre having a height from 0.01 mm to 1 mm, preferably 0.05 mm to 0.2 mm.
  • the percentage of attachment embossed areas to unembossed or fine embossed areas of the total surface area of a paper tissue product is preferably 0.01% to 5%.
  • Attachment embossing involves as substantive densification of the paper tissue products as to achieve the attachment. Therefore the space between and embossing element and its counterpart, eg.
  • two pins where pin-to-pin embossing is employed is less that the calliper of the paper tissue to be embossed, typically 5% to 50%, preferably 10% to 20% of the calliper of the paper tissue to be embossed, which leads to embossing pressures of 10 000 to 50 000 N/square centimetre.

  • the indicia may be applied to either or both of the surfaces of the paper tissue products.
  • the indicia may cover all or part of the paper tissue products and be applied in a continuous or discontinuous pattern.
  • the indicia may be applied to the paper tissue products by any means well known in the art, such as spraying, extruding, and preferably printing. Either gravure or flexographic printing may be utilized. If printing is selected as the means for applying the indicia, the printing apparatus may be constructed according to the teachings of commonly assigned U.S. patent 5,213,037 issued May 25, 1993 to Leopardi, II.
