摘　　要：对非离子聚氨酯干法面层的吸湿透气行为进行了研究。讨论了非离子共聚组分的引入对聚氨酯合成革吸湿透气行为的影响。结果表明亲水基团PEG的引入可以提高合成革吸湿透气性能。并且微相分离大的吸湿透气性能差。At present the urgently problem in synthetic leather tield is the distinctness difference of moisture absorption＇s ability between synthetic leather and savageness leather. The non- ion polyurethane dry coating＇s moisture absorption＇ s ability was studied. And the influence of the non - ion copolymer composition＇ s introduce in polyurethane synthetic leather were discussed. The result showed that the PEG could enhance the moisture absorption＇ s ability of synthetic leather. And if the degree of Microsphase Seperation was enhanced, the leather＇ s moisture absorption＇ s ability would go down.
