摘　　要：超细纤维合成革(简称超纤革)是替代天然皮革的理想材料,但超纤革的透水汽性能与天然皮革相比仍存在差距,有待提升。文章概述了超纤革的制备过程,分析了超纤革的性能及其在透水汽性能方面的不足,并从超纤革的主要组分,即超纤革基布和聚氨酯树脂入手,探讨了超纤革透水汽性能研究的最新进展;总结了对超纤革基布的水解、增加活性基团和亲水剂等改性方法,阐述了对聚氨酯树脂的填料、接枝聚合和共混等改性措施,探讨了对超纤革的后整理改性选项,最后提出了超纤革透水汽性能研究的未来发展方向。Microfiber synthetic leather is an ideal material to replace natural leather,but its water vapor permeability performance is still far from that of natural leather.The process of preparing microfiber leather was discussed in this paper,and the properties of microfiber leather and its deficiencies in water vapor permeability were analyzed.Specifically,the progress of research on the water vapor permeability of microfiber leather was discussed from the two main components of microfiber leather,namely microfiber leather base fabric and polyurethane resin.The modification of microfiber leather base fabric by hydrolysis,the addition of reactive groups and hydrophilic agents was summarized.The modification of polyurethane resin by filler,graft polymerization and co-blending was also discussed.Moreover,the modification of microfiber leather by finishing was discussed.Finally,the research direction for the water vapor permeability of microfiber leather was proposed.
