ABSTRACT:
A product is obtained by a process involving binding two or more layers of tissue fabrics derived from cellular pulp or cellulose fiber. In this process, a binder composition comprised of: (a) 10 to 80 parts by weight of an aqueous plastics dispersion of a solids content of 30 to 70% by weight and based on one or more copolymers comprising vinyl acetate/ethylene copolymers, vinyl acetate/ethylene/N-methylol(meth)acrylamide terpolymers, alkyl acrylate/N-methylol(meth)acrylamide copolymers and vinyl acetate/ethylene/alkyl acrylate copolymers, or vinyl acetate/alkyl acrylate copolymers, which optionally have a N-methylol (meth)acrylamide content, (b) 50 to 300 parts by weight of a filler which has an average particle size of 0.5 to 100 .mu.m, and (c) 0 to 4 parts by weight of a thickener and/or at least 0.1 parts by weight of a dispersing agent to a portion of a single layer of tissue, affixing a further single layer of tissue and drying to obtain a prelaminate. (2) An additional binder composition is applied to this prelaminate thereby affixing a further single layer of tissue, and drying. Optionally, step (2) can be repeated one or more times.
