The present invention relates to the use of polymers comprising a block copolymer containing at least one group A and at least one group B in which each group A is a polymeric block built up from an ethylenically unsaturated polymerisable monomer and each group B is a polymeric block built up from an alkylene oxide, alkylene glycol or cyclic ether monomer or a mixture thereof for promoting soil release during laundering of a textile fabric and processes for their preparation. Laundry cleaning compositions comprising such polymers, a method of promoting soil release during laundering of a textile fabric and the use of such polymers in the manufacture of a laundry cleaning composition for effecting soil release from a laundry item form other aspects of the invention.
本发明涉及包含至少一个基团A和至少一个基团B的嵌段共聚物的聚合物的用途,其中每个基团A是由
乙烯不饱和可聚合单体形成的聚合物嵌段,每个基团B是由环氧烷、亚烷基二醇或
环醚单体或其混合物形成的聚合物嵌段,用于促进纺织织物洗涤过程中的泥土释放及其制备工艺。包含这种聚合物的洗衣清洁组合物、在洗涤纺织织物过程中促进泥土释放的方法以及在制造洗衣清洁组合物过程中使用这种聚合物以实现从衣物中释放泥土的方法构成了本发明的其他方面。
