摘要: 为了减少羊毛蛋白酶防毡缩造成的损伤,应用TG酶对羊毛织物进行整理,研究TG酶对羊毛损伤的修复作用。结果表明:TG 酶可以修复化学预处理和蛋白酶防毡缩处理对羊毛造成的损伤,使羊毛织物强力增加,碱溶度下降。TG酶可以催化羊毛纤维蛋白质分子内的交联。羊毛的蛋白酶/TG酶联合防毡缩的最佳工艺为: 蛋白酶Sav用量1%(o.w.f.), 蛋白酶Sav作用时间30min,pH值8~9;TG酶用量2%(o.w.f.),TG酶作用时间50min,pH值6~7;浴比均为20:1,温度均为50℃,该工艺处理后羊毛织物的毡缩率为2.93%, 强力380.4N,强力损伤控制在7.4%。

Abstract: Wool fabrics` were finished with TG enzyme in order to decrease the damage of wool resulting from anti-felting treatment with protease. The remedy effect of TG enzyme to the damage of wool was studied. It was shown that TG enzyme can remedy the damage of wool caused by chemical pre-treatment and protease anti-felting finishing, increasing wool fabric strength and decreasing the alkali solubility. TG was capable of catalyzing covalent crosslinking of wool proteins. The optimum protease/TG anti-felting finishing conditions: dosage of protease, 1%(o.w.f.); time, 30min; pH=8~9; dosage of TG, 2%(o.w.f); time, 50min; pH=6~7; bath radio 20:1; and temperature, 50℃. The percentage area shrinkage of the wool fabric treated by this optimal process was 2.93%, the strength was 380.4N and the loss in strength was controled within 7.4%.
