摘要： This invention is directed to an improvement in binders particularly suited for use in preparing nonwoven products and to the nonwoven products. The improved binders comprise a blend of emulsion polymerized ethylene-vinyl chloride (EVCl) polymer and an emulsion polymerized self crosslinkable vinyl acetate-ethylene-N-methylolacrylamide (VAE-NMA) polymer. The blends of the EVCl polymer emulsion and the VAE-NMA polymer emulsion can be applied to cellulose and cellulose/synthetic nonwoven substrates and cured in the absence of an acid catalyst to provide a self-sustaining web having excellent wet strength performance. The blends of EVCl and VAE-NMA polymers do not require an acid catalyst to facilitate cure.

摘要： A crepe process includes applying an adhesive composition to a nonwoven web, drying, and creping the nonwoven web on a creping drum. The improvement includes using an adhesive composition that includes an aqueous copolymer dispersion obtained by emulsion polymerization of a monomer mixture including 65 to 94.5% by weight of vinyl acetate, 5 to 30% by weight of ethylene, (meth)acrylamide, and 0.1 to 4% by weight of an N-methylol functional monomer. The N-methylol functional monomer constitutes from 25 to 85% by weight of the combined amounts of acrylamide and N-methylol functional monomer, which combined amounts constitute from 0.5 to 5% by weight of the monomer mixture. The emulsion polymerization is performed in the presence of 1 to 10% by weight of polyvinyl alcohol, based on the total weight of all monomers used for the polymerization. The adhesive composition does not include alkylphenol ethoxylates, phosphate ester surfactants, or sodium laureth sulfate.

摘要： This invention relates to an improvement in coatings particularly suited for the preparation of paper products having an ink jet coating applied thereto and to the resulting paper products. The improvement in ink jet coatings resides in the incorporation of a primary amine functional polyvinyl alcohol (PVOH/PVNH2) as a polymeric binder. One form of an amine functional polyvinyl alcohol is produced by the hydrolysis of a copolymer of vinyl acetate and N-vinylformamide or vinyl acetate and allyl amine. Another is the polyvinyl butyral derivative of polyvinyl alcohol which typically is formed by the reaction of a 4-amino alkyl aldehyde dialkyl acetal, such as 4-aminobutyraldehyde dimethyl acetal with polyvinyl alcohol.

摘要： Production of a paper coating composition having improved low shear viscosity at a high solids level of fine particle size calcium carbonate. The improvement in low shear viscosity is achieved by dissolving a fine particle size, partially hydrolyzed, low molecular weight poly(vinyl alcohol) powder in an aqueous slurry of pigment particles containing predominantly fine particle size calcium carbonate. Dissolution of the poly(vinyl alcohol) is achieved without external heating or adding water to the slurry. The slurry can then be formulated with other components to produce the ink jet paper coating composition which, when applied to a paper substrate, provides excellent ink jet printability.
