    • The present invention is concerned with a method for improving the water storage capacity of textile substrates, particularly fleece based artificial leathers by treatment with a hydrophilizing agent. This agent, once applied to the substrate is insoluble in but swellable in water. The agent in an uncross-linked state is water soluble and has a turbidity point of between about 25.degree. and 95.degree. C. in a 25% aqueous solution. The agent may be applied to the substrate from aqueous solution and then cross-linked or it may be applied to an inert carrier such as kaolin, cross-linked and applied to the substrate from an aqueous suspension. A particularly suitable agent is a polyether with a molecular weight of between 500 and 8500, an ethylene oxide content of about 35 to 80 wt. % and cross-linkable end groups. The end groups may be self cross-linking such as vinyl groups or they may be cross-linkable via a cross-linking promoter such as hexamethylol melamine. These end groups include the hydroxyl groups normally present in polyethers produced from polyalkylene oxides.
    • 本发明涉及通过用亲水剂处理改善纺织品基材,特别是羊毛基人造革的储水能力的方法。 一旦施加到基底上,该试剂不溶于水,但在水中溶胀。 未交联状态的药剂是水溶性的,并且在25%水溶液中的浊点为约25至95℃。 该试剂可以从水溶液施加到基材上,然后交联,或者可以将其施加到惰性载体如高岭土上,交联并从水悬浮液中施加到基材上。 特别合适的试剂是分子量为500至8500的聚醚,环氧乙烷含量为约35至80重量%。 %和可交联的端组。 端基可以是自交联,例如乙烯基,或者它们可以通过交联促进剂如六羟甲基三聚氰胺交联。 这些端基包括通常存在于由聚环氧烷生成的聚醚中的羟基。
