    • 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.
    • 通过涉及结合来自细胞纸浆或纤维素纤维的两层或更多层织物织物的方法获得产品。 在该方法中,粘合剂组合物包含:(a)10至80重量份固体含量为30至70重量%的水性塑料分散体,并基于一种或多种包含乙酸乙烯酯/乙烯共聚物的共聚物,乙烯基 乙酸酯/乙烯/ N-羟甲基(甲基)丙烯酰胺三元共聚物,丙烯酸烷基酯/ N-羟甲基(甲基)丙烯酰胺共聚物和乙酸乙烯酯/乙烯/丙烯酸烷基酯共聚物,或乙酸乙烯酯/丙烯酸烷基酯共聚物,其任选具有N-羟甲基 甲基)丙烯酰胺含量,(b)50〜300重量份的平均粒径为0.5〜100μm的填料,(c)0〜4重量份的增稠剂和/或至少0.1份 的分散剂施加到单层组织的一部分,固定另外的单层组织并干燥以获得预层压。 (2)将另外的粘合剂组合物施加到该预层压板上,从而固定另外的单层组织并干燥。 可选地,步骤(2)可以重复一次或多次。
