摘　　要：棉织物的抗皱整理已不能满足当代人对"易护理"纺织材料的需求。传统可改善棉织物抗皱性的耐久定型整理大多基于N-羟甲基甲醛化合物,如二-羟甲基二羟基乙烯脲(DMDHEU)或其衍生物与棉纤维在高温下缩合反应而获得。然而,此定型整理过程中释放的甲醛已被认为是潜在的人类致癌物。过去20年来,人们致力于开发无甲醛交联剂,最具发展潜力的无甲醛试剂当属1,2,3,4 BTCA的多羧酸及马来酸的聚合物。由于1,2,3,4 BTCA的成本高于聚马来酸,因此商业应用较复杂。与纤维素底物进行酯交联的反应由次磷酸钠进行催化。讨论了聚马来酸的应用,研究了它对棉织物各种性能(如抗皱回复角、拉伸强度、撕裂强度及耐磨性等)的影响,并比较了经聚马来酸和DMDHEU处理的织物的性能。The crease resistance of cotton fabrics is not satisfactory to meet the contemporary requirements for ＂easycare＂textile materials. The conventional durable press finishes which improve the crease-resistance of cotton fabrics are mostly achieved on the basis of a condensation reaction at high temperature between formaldehyde based N-methylol compounds,such as Di-Methylol Dihydroxy Ethylene Urea（ DMDHEU） or its derivatives and cotton. However,the formaldehyde,which is released during the fixation procedure,has been identified as a potential human carcinogen. In the last 2 decades many efforts have been made to develop formaldehyde- free cross-linking agents. The most promising formaldehyde-free reagents,nevertheless are the polycarboxylic acids are 1,2,3,4 BTCA and polymers of maleic acid. Predominantly 1,2,3,4 BTCA is higher cost than polymaleic acid,so commercial application is an intricate. The reaction with the cellulose substrate proceeds ester cross-linking,catalyzed by sodium hypophosphite. This work deals with the application of polymaleic acid,and its impact on various properties of cotton such as crease resistance angle（ CRA）, tensile strength,tearing strength and abrasion resistance were investigated. Finally PMA treated fabric was compare with DMDHEU treated fabrics.
