水性无纺物粘合剂和由其制备的经过处理的无纺物
摘要：
本发明揭示一种水性无纺物粘合剂，其包含乳液聚合物，所述乳液聚合物包含作为共聚单元的：以所述乳液聚合物的重量为基准计，0.1-5重量％的单烯键式不饱和二羧酸单体；以所述乳液聚合物的重量为基准计，12-22重量％的单烯健式不饱和单酸单体；其中所述乳液聚合物的计算Tg为-20℃到30℃，所述粘合剂使经过处理的无纺物基材具有有利的湿强度和分散性之间的平衡。
摘要（英）：

An aqueous nonwoven binder including an emulsion polymer including, as copolymerized units: from 0.1% to 5% monoethylenically-unsaturated dicarboxylic acid monomer by weight, based on the weight of the emulsion polymer; and from 12% to 22% monoethylenically-unsaturated monoacid monomer by weight, based on the weight of the emulsion polymer wherein the calculated Tg of the emulsion polymer is from -20 DEG C to 30 DEG C that is capable of providing a useful balance of wet strength and dispersibility to a treated nonwoven substrate is provided.
