摘　　要：针对粘胶织物树脂免烫整理后甲醛含量偏高的实际问题,试验从改变纤维表面结构、织物预处理和添加助剂等方面探讨改进的措施,包括:1000 U/L纤维素酶抛光预处理、2%的NaOH预处理、湿态进布(轧余率50%~100%)、轧液前75 W超声处理5 min、整理浴添加6%的乙二醇、20~30 g/L甲醛捕捉剂或3~5 g/L渗透剂,以及使用30%~50%的聚氨酯代替2D树脂等,均可降低树脂整理后粘胶织物的甲醛含量且不影响免烫性能。Aiming at the practical problem of high formaldehyde emission after resin finishing of viscose fabric,the possible improvement measures are put forward from the aspects of changing the fiber surface structure,pretreatment and adding additives.The results show that the optimized process can reduce the formaldehyde content of viscose fabric after resin finishing without affecting DP grade,that is,1000 U/L cellulase polishing pretreatment,2% NaOH pretreatment,wet cloth feeding(pickup rate 50%-100%),75 W ultrasonic for 5 min before padding,and adding 6% ethylene glycol,20-30 g/L formaldehyde capture agent or 3-5 g/L penetrant,and 30%-50% polyurethane instead of 2D resin in finishing bath.
