摘　　要：在不同预聚反应条件(预聚物摩尔比、反应温度、反应时间)下合成的水性聚氨酯产品,研究其作为免烫整理添加剂,对棉织物免烫整理效果的影响.结果表明:预聚反应中,聚乙二醇分子量为400～800,能够提高整理织物的回复角;PE与TDI的摩尔比对提高织物回复角也有一定影响.The water-soluble polyurethane is prepared under various prepolymerized conditions, such as prepolymer mole ratio,reaction temperature and time. Effects of polyurethane as an additive on DP results of cotton fabric are discussed. It is shown that in the polymerization, polyethylene with molecular weight 400 - 800 can impart the cotton fabric enhanced recovery angle,mole ratio Of PE to TDI will also exert influence on the cottons recovery angle.
