Abstract: A disposable, cloth-like towel of superior wet strength and absorbency comprises a scrim coated with a superabsorbent material, with one or more nonwoven fibrous webs bonded to the coated scrim. The superabsorbent coating preferably is formed by wetting the scrim with water or an aqueous adhesive, applying a solid hydrophilic polymer to the scrim, then applying a nonwoven absorbent cellulosic web to the coated scrim and drying the resulting composite laminate. Bonding of the scrim to the nonwoven fibrous web can be achieved by applying an adhesive to the side of the cellulosic web which is brought into contact with the coated scrim.

Abstract: Absorbent paper products, such as towels, absorbent wipes, toilet tissue, facial tissue and the like fibrous webs of relatively high bulk, are produced by a method comprising the steps of treating hydrophilic cellulosie fibers to impart kinks, curls, bends, twists, to the fibers; dispersing the treated fibers in an aqueous forming medium, and wet-forming a stratified single-ply web constituted of at least one stratum of the treated fibers and at least one stratum of conventional paper-making fibers. The treating step may consist of wet or dry mechanical working, chemical treatment or a combination of mechanical and chemical treatments. The web forming step comprises preparing a first aqueous furnish of the treated fibers, preparing a second aqueous furnish of the conventional fibers, and concurrently depositing the two furnishes in contiguous layers on a moving foraminous support.

Abstract: A fibrous web having an enhanced capacity for water absorption is produced by impregnating an absorbent fabric with a polymer or copolymer capable of forming by cross-linking an absorbent polymer or copolymer and subsequently heating the treated fabric effecting cross-linking of the polymer to form an absorbent polymer. The product may comprise a non-woven fibrous web or mat having a water-insoluble binder on one surface and a cross-linked hydrophilic polymer or copolymer on its opposite surface.

Abstract: An apparatus is disclosed for the production of a multi-ply sheet product in which separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, the embossed webs separated from one another and longitudinally displaced realtive to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another. The resulting product exhibits enhanced softness and absorbence as compared with similar products comprising simultaneously embossed multi-ply webs.

Abstract: An absorbent pad structure particularly suited for use in a vacuum package for a food product and the like is disclosed as well as its method of manufacture. The composition of the pad is such as to minimize leakage of liquids into the absorbent material during storage and to permit the flow of liquids freely for absorption during cooking of the packaged product. The pad is particularly suitable for use in bacon packages and other food packages containing oils or grease.

Abstract: A method and apparatus is disclosed for the production of a multi-ply sheet product in which separate non-woven fibrous webs are combined into a multi-ply sheet before embossment, embossed as a multi-ply sheet, the embossed webs separated from one another and longitudinally displaced relative to one another, and then recombined into an embossed multi-ply sheet with the embossments out of register with one another. The resulting product exhibits enhanced softness and absorbence as compared with similar products comprising simultaneously embossed multi-ply webs.

Abstract: A method for forming a fabric web by wet-laying fibers on paper-making equipment, the web comprising staple length natural or synthetic fibers and optionally wood cellulose papermaking fibers and an adsorbed polymeric surface active agent. The method comprises making up an aqueous fiber furnish with a polymeric surfactant having a plurality of both hydrophilic and hydrophobic groupings per molecule. The polymeric surfactant is adsorbed by the fibers and may be added to the fibers or it may be included in the aqueous carrier medium. In either case, the finished web contains and is improved by the inclusion of the polymeric surfactant.

Abstract: A thermosetting resin composition particularly suitable for surface coatings, including metals, paper and paperboard, and especially those papers subsequently converted into shaped paperboard products, e.g. paper plates and folded cartons, with a high gloss, water and oil resistant surface coating. The composition is suitable also as both an adhesive and coating in metallizing substrates by the transfer of metallic particles from a transfer agent to the substrate. When formulated without solvents or dispersants it is suitable for use as a casting composition or as a molding material. The composition comprises a polymer or copolymer containing carboxylic acid groups; an epoxy compound containing an average of more than one epoxide group per molecule; an ammonium or phosphonium base or salt thereof; and a monomeric carboxylic acid or inorganic acid which extends the useful working life of the composition and imparts a superior glass to the surface of the finished product.

Abstract: Anfractuous cellulose fibers exhibiting exceptional high bulking properties are produced by treatment of dry hammermilled wood cellulose fibers with anhydrous liquid ammonia at substantially atmospheric pressure. Fibrous webs of enhanced bulk are produced by preparing an aqueous furnish comprising at least ten percent by weight ammonia treated anfractuous fibers in admixture with conventional papermaking fibers.

Abstract: A method for forming a fibrous web by wet-laying fibers on paper-making equipment, the web comprising staple length natural or synthetic fibers and wood cellulose paper-making fibers wherein a water furnish of the fibers is made up with an associative thickener in the absence of a conventional surfactant. A preferred associative thickener for use with hydrophobic fibers is a urethane block copolymer having a polyethylene glycol backbone, the associative thickener acting as both surfactant and thickener. With predominately cellulosic fibers, i.e. conventional wood cellulose fibers, or a mixture of conventional and contorted wood fibers, and synthetic cellulosic fibers, such as rayon, a hydroxyethyl cellulose having a long alkyl side chain is preferred. Excellent consistency of the water and fiber dispersion is obtained at relatively low viscosity with rapid drainage of water from the wire and uniform formation of the web.

Abstract: A method of embossing a sheet of non-woven fibrous web, e.g. toilet tissue, with a series of identical boss elements arranged in a uniform pattern in a manner to avoid nesting of the embossments and resulting non-uniform product rolls when the sheet is rolled onto a mandrel. The embossments are uniformly spaced in rows which in the longitudinal direction form an angle in the range of 15.degree. to 23.degree. relative to the edge of the sheet or roll and an angle in the range of 40.degree. to 57.degree. relative to the cross direction of the sheet or roll.

Abstract: A paper cup or similar disposable thin-walled fluid container with a removable or pop-out portion in its sidewall containing redemption information is disclosed wherein the pop-out portion is formed by a series of surrounding perforations in the sidewall, which perforations are sealed against fluid leakage by being filled with the protective material, such as wax, that is used to coat the sidewall to protect it against the fluid in the container. The perforations may outline an integral portion of the sidewall or when the redemption indicia is to be obscured, separate portions at the opposite edges of the sidewall blank may be outlined, which portions will cooperate to form the pop-out portion as part of the sidewall seam when the edges are overlapped and joined. In the latter instance, the perforations extend into the sidewall beyond the limits of the seam so that an opening will occur in the sidewall when the pop-out portion or a part thereof is removed to view the prize indicating indicia.
