Definitions

  • the present invention relates to a process for making a multi-ply tissue, and in particular a facial tissue, and disposable handkerchiefs.
  • Paper webs or sheets sometimes called tissue or paper tissue webs or sheets, find extensive use in modem society. Such items as facial and toilet tissues are staple items of commerce. It has long been recognised that four important physical attributes of these products are their strength, their softness, their absorbency, including their absorbency for aqueous systems; 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 is the tactile sensation perceived by the consumer as he/she holds a particular product, rubs it across his/her skin, or crumples it within his/her hand. This tactile sensation is a combination of several physical properties.
  • One of the more important physical properties related to the softness is generally considered by those skilled in the art to be the stiffness of the paper tissue from which the product is made. Stiffness, in turn, is usually considered to be directly dependent on the dry tensile strength of the web.
  • 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 human consumer is generally considered to be a combination of the total quantity of a liquid a given mass of tissue paper 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.
  • Example 3 discloses a two-ply facial tissue having a basis weight of about 32 g/m 2 (20 lbs/3000 sq. ft.)
  • the tissue of this example comprises 0.475% of a wet strength resin.
  • Disposable paper products having high wet burst strength are known, for example BountyTM, sold by The Procter & Gamble Company, has a wet burst strength which is greater than 200 g.
  • BountyTM sold by The Procter & Gamble Company
  • kitchen towels are embossed over the whole surface which results in a surface texture which is rough and does not provide a suitably smooth wiping surface for blowing the nose.
  • Facial tissues are commercially available comprising at least two plies, the tissue having a surface area in one plane, and a thickness orthogonal to the plane, wherein the thickness is a caliper of at least 0.35mm, and wherein the tissue has an unembossed wiping surface over a major part of the surface area of the tissue.
  • the rather low wet burst strength of today's facial tissues often results in tearing or bursting which in turn results in contamination of the user's hand with mucus or other bodily fluids.
  • the object of the present invention is a process to provide a multi-ply facial tissue having at least the desired softness and absorbency of known facial tissues, but also providing enhanced protection against tearing or bursting when used, in particular when used for blowing the nose.
  • the object of the invention is achieved by a process for the manufacture of a multi-ply tissue, wherein the process comprises the steps of:
  • the present invention may contain, as a highly preferred component, up to about 3.0%, preferably at least 0.5%, and more preferably at least 0.8% by weight, on a dry fiber weight basis, of wet strength chemical agent, such as water-soluble permanent and temporary wet strength resin.
  • wet strength chemical agent such as water-soluble permanent and temporary wet strength resin.
  • 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 28 th , 1974 teaches that chemical debonding agents can be used to reduce the stiffness, and thus enhance the softness, of a tissue paper 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 tissue paper 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".
  • tissue paper of the present invention may use common methods well-known to the person skilled in the art, such as dewatering suitable pulp using, for example, one or more papermakers felts and/or belts.
  • At least one ply of the tissue paper obtained by the process of the present invention has two primary regions.
  • the first region comprises an imprinted region which is imprinted against the framework of the papermaking belt.
  • the imprinted region preferably comprises an essentially continuous network.
  • the continuous network of the first region of the paper is made on the essentially continuous framework of the belt and will generally correspond thereto in geometry and be disposed very closely thereto in position during papermaking.
  • the second region of the paper comprises a plurality of domes dispersed throughout the imprinted network region.
  • the domes generally correspond in geometry, and during papermaking in position, to the deflection conduits in the belt.
  • the domes protrude outwardly from the essentially continuous network region of the paper, by conforming to the deflection conduits during the papermaking process.
  • the fibers in the domes are deflected in the Z-direction between the paper facing surface of the framework and the paper facing surface of the reinforcing structure.
  • the domes are discrete.
  • the domes and essentially continuous network regions of the paper may have generally equivalent basis weights.
  • the density of the domes is decreased relative to the density of the essentially continuous network region.
  • the essentially continuous network region (or other pattern as may be selected) may later be imprinted as, for example, against a Yankee drying drum. Such imprinting increases the density of the essentially continuous network region relative to that of the domes.
  • the process for making a paper according to the present invention may be run according to any of commonly assigned U.S. Patents: 4,529,480, issued July 16, 1985 to Trokhan; 4,637,859, issued Jan. 20, 1987 to Trokhan; 5,364,504, issued Nov. 15, 1994 to Smurkoski et al.; and 5,529,664, issued June 25, 1996 to Trokhan et al. and 5,679,222 issued Oct. 21, 1997 to Rasch et al.
  • the paper may be dried and made on a through-air drying belt not having a patterned framework. Such paper will have discrete, high density regions and an essentially continuous low density network. During or after drying, the paper may be subjected to a differential vacuum to increase its caliper and dedensify selected regions.

  • Such a belt may be utilized as a forming wire, drying fabric, imprinting fabric, transfer clothing etc.
  • a jacquard weave is reported in the literature to be particularly useful where one does not wish to compress or imprint the paper in a nip, such as typically occurs upon transfer to a Yankee drying drum.
  • Illustrative belts having a jacquard weave are found in U.S. Pat. Nos. 5,429,686 issued July 4, 1995 to Chiu et al. and 5,672,248 issued Sept. 30, 1997 to Wendt et al.
  • the plies may, optionally, be attached together by means, for example, of gluing or embossing. Gluing is less preferred because it tends to result in a stiffer, less soft product. Indeed it is preferred that no glue is used to attach the plies. Embossing may be used to attach the plies together, for example, as disclosed in EP-A-0 755 212, published on 29 th January 1997.
