摘　　要：针对制革过程中聚乙烯醇(PVA)退浆废水降解性差、严重污染环境等问题,采用PVA、水溶性聚酯(WSPET)、羧甲基纤维素钠(CMC)、海藻酸钠(SA)、白糖(WS)5种聚合物对海岛型超细纤维非织造布进行上浆处理,经水性聚氨酯(WPU)含浸制成超纤革,研究了不同浆料对超纤革性能的影响。结果表明:上浆处理有助于提高超纤革透气透湿性、柔软性能及力学性能,透湿率、透气性、柔软度分别提高了123.5、184.7、37.7%;经PVA、WSPET以及CMC上浆处理的超纤革,透湿透气性及柔软度性能相近;而经SA、WS上浆处理的超纤革透湿透气性及柔软度性能较差;通过综合性能的对比分析,WSPET、CMC可作为一种经济环保、可持续发展的上浆原料应用于超纤革制备过程。In view of the poor degradability of polyvinyl alcohol(PVA)desizing wastewater during the preparation of microfiber synthetic leather,and serious environmental pollution,PVA,water-soluble polyester(WSPET),sodium carboxymethyl cellulose(CMC),sodium alginate(SA),and white sugar(WS)were used for sizing the island-in-sea microfiber nonwoven fabric,and impregnated with water-based polyurethane(WPU)to make microfiber synthetic leather.The effects of different size mixtures on the properties of microfiber leather were investigated.The results indicated that the sizing treatment can improve the air permeability,moisture permeability,softness and mechanical properties of the microfiber synthetic leather,and the water vapor permeability,air permeability and softness were increased by 123.5,184.7 and 37.7%,respectively.The microfiber synthetic leathers treated by PVA,WSPET and CMC sizing exhibited similar water vapor permeability,air permeability and softness.While,the microfiber synthetic leathers treated by SA and WS sizing had poor water vapor permeability,air permeability and softness.Through comprehensive analysis of performance,WSPET,CMC can be used as an economical,environmentally friendly and sustainable size mixture for the preparation of microfiber synthetic leather.
