羊毛生物酶联合防毡缩整理
|
摘要
针对传统的氯化法羊毛防毡缩技术对环境污染严重,单一蛋白酶防毡缩整理技术效果不理想,一浴两步酶处理法工艺流程长、强力损伤大等问题,采用蛋白酶与生物酶活化剂联合组成的混合溶液协同对羊毛进行一浴一步浸轧处理,实现羊毛的生态快速无氯防毡缩整理。选用三羧基乙基膦分别与蛋白酶8.0T、蛋白酶2.5L、蛋白酶16L组成的混合溶液对羊毛纤维进行处理,测试处理后羊毛的断裂强力、断裂伸长、毡缩球密度,借助扫描电子显微镜观察分析处理后羊毛鳞片层的形貌。结果表明,三羧基乙基膦分别与3种蛋白酶联合处理羊毛的防毡缩效果均显著,且蛋白酶16L的防毡缩效果为最佳。通过正交试验优化得出最佳工艺条件:蛋白酶16L质量浓度为1.8 g/L,三羧基乙基膦质量浓度为1.0g/L,处理温度为50℃,处理时间为2 min。
In view of serious environmental pollution of conventional chlorination wool anti-felting technology,unsatisfactory finishing effect of single protease antifelting, long-time treatment and strength damage of one-bath-two-step enzyme treatment process, a mixed solution composed of a protease and a bio-enzyme activator was used to anti-shrinkage finish the wool to achieve an ecological, fast, chlorine-free and felt-proof finishing.The wool fiber was treated with a mixed solution of tricarboxyl ethyl phosphine and protease 8.0 T, protease 2.5 L and protease 16 L respectively, according to the treated wool′s breaking strength, elongation at break, and felt shrinkage ball density test results,combined with scanning electron microscopy observation and analysis of the scaly layer of wool after treatment,it was concluded that the anti-felting effects of the tricarboxyl ethyl phosphine combined with the three proteases in treating wool are significant, and the anti-felting effect of the protease 16 L is the best.The optimum process conditions obtained by orthogonal test optimization are as follows: the amount of protease 16 L of 1.8 g/L, the amount of tricarboxyl ethyl phosphine of 1.0 g/L, the processing temperature of 50 ℃, and the processing time of 2 min.
