摘要
根据苎麻纤维的结构特点及果胶酶的作用机理,通过单因素试验和正交试验优化苎麻织物果胶酶精练工艺:果胶酶12g/L,渗透剂JFC2g/L,pH值8,温度50℃,时间1. 5h;精练后用活性染料染色,讨论了酶处理对苎麻织物染色性能的影响,并与碱处理后再染色的苎麻织物的染色性能作比较。比较发现,酶处理织物得色比碱处理浅,固色百分率略低;两种前处理半制品染色后的摩擦牢度和耐洗牢度都较好,且相差不大。
The characteristics of ramie fiber and function mechanism of pectase were described. Based on trials, the optimal scouring process of ramie fabric with pectase was as follows: pectase 12 g/L, penetrating agent JFC 2 g/L, pH value 8, temperature 50℃, time 1.5h. The scoured ramie fabric was then dyed with reactive dye, and the influence of pectase treatment on dyeing property of ramie fabric was discussed. The dyeing properties of alkali treated fabric and pectase treated fabric were compared. It is found that the shade of pectase treated fabric was lighter than that of alkali, and the fixation yield of pectase treated fabric was also lower, while the rubbing fastness and washing fastness of both fabrics were better and almost the same.
