摘　　要：将自制的金属蛋白催化剂MPC应用于分散染料染色涤纶和涤棉混纺织物的还原清洗工艺。优化的还原清洗工艺为:保险粉10 g/L、MPC催化剂2 g/L,氢氧化钠4 g/L,一浸一轧,85℃汽蒸90 s。与传统还原清洗效果比较,MPC可以催化保险粉分解,有效去除染色织物上的浮色,减少保险粉及氢氧化钠的用量,降低处理温度。The self-made metalloprotein catalyst MPC is applied to the reduction clearing process of polyester and polyester/cotton blended fabrics dyed with disperse dyes.The optimized reduction clearing process is as follows:10 g/L sodium hydroxide,2 g/L MPC catalyst,4 g/L sodium hydroxide,one-dip-one-nip,and steam⁃ing at 85℃for 90 s.Compared with traditional reduction clearing,MPC can catalyze the decomposition of sodi⁃um hydroxide,effectively remove loose colors on dyed fabrics,reduce the amounts of sodium hydroxide and sodium hydroxide,and lower the processing temperature.
