摘　　要：将丁烷四羧酸(BTCA)、柠檬酸(CA)及水解淀粉混合,对棉织物进行无甲醛防皱整理,研究淀粉用量、BTCA与CA摩尔分数比及其用量、次亚磷酸钠和三乙醇胺用量、焙烘温度及焙烘时间等对整理效果的影响。试验结果得到其优化工艺为:、淀粉2%,BTCA与CA的摩尔分数比为1∶3、多元羧酸8%、次亚磷酸钠6%、三乙醇胺2%、渗透剂JFC 2 mL/L,180℃焙烘90 s。整理后棉织物的湿缓弹折皱回复角从175.1°提高到266.5°,强力保留率有所下降,白度下降不大,且具有较好的耐水洗性能。整理对染色棉织物的K/S值有一定的影响,对染色牢度基本没有影响。Formaldehyde-free anti-crease finish is carried out on cotton fabric with 1,2,3,4-butanetetracarboxylic acid （BTCA）, citric acid （CA） and hydrolyzed starch. Factors exerting influence on finishing results are discussed, such as dosage of starch, polycarboxylic acid, sodium hypophosphite and triethanolamine, mole ratio of BTCA to CA, curing temperature and curing time. The results show that the optimum process of anti-crease finish is starch 2%, mole ratio of BTCA to CA 1 ：3, polycarboxylic acid 7%, sodium hypophosphite 6%, triethanolamine 2%, JFC 2 mL/L, curing at 180 ℃ for 90 s. Wet crease recovery angle of the finished fabric has increased to 266.5°from 175. 1°, breaking strength retention rate decreased, whiteness reduced lightly, washability is good. The finish has influence on K/S value of dyed cotton fabric, but has no effect on color fastness.
