Tissue paper
To provide tissue paper with an excellent “moist texture” and high “smooth texture.” 2-ply tissue paper is characterized by the basis weight per ply being less than 13 g/m.sup.2, the 2-ply paper thickness being less than 135 μm, and containing above 1.4 g/m.sup.2 and less than 4.9 g/m.sup.2 of chemical agent which contains glycerin and 1,3-propanediol in a total amount of 83 mass % or more, wherein the mass ratio of glycerin and 1,3-propanediol is above 1:0.18 and less than 1:5.11.
TISSUE PAPER AND TISSUE PAPER PRODUCT
To provide a three-ply or four-ply tissue paper that reduces a sticky feeling of an outer surface while securing necessary softness, and a method for manufacturing the same.
A tissue paper including three stacked plies or four stacked plies, wherein each ply contains an aqueous moisturizer exhibiting hygroscopicity, and the content of the aqueous moisturizer between the plies is set such that the dry moisturizer content percentage of each ply is within a range of 92.0 to 108.0 when the dry moisturizer content percentage of a product is 100.
THROUGH-AIR APPARATUS TO REDUCE INFILTRATION OF AMBIENT AIR
A through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is provided. The apparatus includes a web-carrying structure configured to move and a first component having at least one sealing element adjacent the web-carrying structure, where the sealing element is configured to reduce the infiltration of ambient air into the through-air apparatus. The apparatus also includes at least one channel configured to direct air to the sealing element to reduce the infiltration of ambient air into the through-air apparatus. A method of operating a through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is also provided. The method includes directing air to a sealing element to reduce the infiltration of ambient air into the through-air apparatus.
PAPER TOWEL PRODUCTS AND METHODS OF MAKING THE SAME
A two-ply rolled Through Air Dried paper towel with high total absorption and absorption rate at a low basis weight. Further, the paper towel has a unique combination of properties including an Sdr value of greater than 30, and a Vvd value of greater than 4.
Pre-moistened fibrous structures exhibiting increased capacity
Pre-moistened fibrous structures containing filaments and solid additives, wherein the fibrous structures exhibit capacity values that are superior to known pre-moistened fibrous structures as measured according to the Capacity Test Method described herein and methods for making same are provided.
Water-dispersible composite structure and method of producing the same
A water-dispersible composite structure, which comprises one or more layers, and a method of producing the same. At least a part of the layers is formed by a fibrous web or sheet containing 50-90 parts by weight of wood fibers and 10-90 parts by weight of annual or perennial plant fibers and/or 10-50 parts by weight of synthetic short-cut fibers, and 0.1-20% by weight of a binder, calculated from the weight of the fibers, and at least a part of the binder being a water-soluble polymer and another part a water dispersible binder, and the fibrous sheet or web being produced by wet forming. By means of the invention, the fibers of the composite structure can be recovered and recycled by equipment conventionally used in the paper and paperboard industry.
TISSUE PAPER
Provided is 3-ply tissue paper suitable for performing “tissue off” and excellent in softness and smoothness.
In the 3-ply tissue paper containing an aqueous moisturizer, a paper thickness for three plies is 176 to 230 μm, an arithmetic mean roughness Sa is 0.007 to 0.020 mm, and a compression work is 1.70 to 2.40 gf.Math.cm/cm.sup.2 and a compression recovery rate is 46.0 to 54.5% for four sets of three plies, twelve plies in total.
Grafted crosslinked cellulose
Grafted, crosslinked cellulosic materials include cellulose fibers and polymer chains composed of at least one monoethylenically unsaturated acid group-containing monomer (such as acrylic acid) grafted thereto, in which one or more of said cellulose fibers and said polymer chains are crosslinked (such as by intra-fiber chain-to-chain crosslinks). Some of such materials are characterized by a wet bulk of about 10.0-17.0 cm3/g, an IPRP value of about 1000 to 7700 cm2/MPa.Math.sec, and/or a MAP value of about 7.0 to 38 cm H2O. Methods for producing such materials may include grafting polymer chains from a cellulosic substrate, followed by treating the grafted material with a crosslinking agent adapted to effect crosslinking of one or more of the cellulosic substrate or the polymer chains. Example crosslinking mechanisms include esterfication reactions, ionic reactions, and radical reactions, and example crosslinking agents include pentaerythritol, homopolymers of the graft species monomer, and hyperbranched polymers.
Paper tissue with high bulk and low lint
A tissue paper product is provided having at least one ultra-low density ply having a highly porous, open-celled structure and that comprises cellulosic fibers, a water insoluble binder and a foaming surfactant. The cellulosic fiber comprises greater than 50% by weight of the ply and are bonded to one another by hydrogen bonding. Further, the ply has a density less than about 0.04 g/cc and yet still provides low lint and high strength properties with the use of minimal binder. The ultra-low density ply may comprise or be included in sheets forming a stack of dispensable wipers or may be employed as or part of an absorbent core or liquid distribution layer of a personal care absorbent personal care product such as a diaper or feminine pad.
Fibrous structure-containing articles
Articles, such as sanitary tissue products, including fibrous structures, and more particularly articles including fibrous structures having a plurality of fibrous elements wherein the article exhibits differential cellulose content throughout the thickness of the article and methods for making same are provided.
