摘要
为解决羊毛织物防毡缩处理后力学性能受损的问题,使用L-半胱氨酸改善羊毛的防毡缩性能,并采用漆酶催化阿魏酸交联羊毛织物,探讨L-半胱氨酸预处理及酶法交联改性处理对织物强力的修复机理。结果表明:采用L-半胱氨酸处理后羊毛织物的毡缩率由原先的18.67%降低至6.84%,但断裂强力经向损失34.77%,纬向损失32.81%,断裂伸长率经向提升13.18%,纬向提升19.88%;使用漆酶催化阿魏酸交联羊毛织物后,断裂强力经向修复14.21%,纬向修复13.54%,织物毡缩率下降至6.49%,满足面料的防毡缩要求,且断裂强力得到有效修复,实现了羊毛的酶法低损伤防毡缩整理。
In order to solve the problem of mechanical property damage of wool fabrics after anti-felting shrinkage treatment,L-cysteine was used to improve the anti-felting shrinkage performance of wool,and laccase-catalyzed cross-linking of ferulic acid was used to cross-link wool fabrics,to investigate the restoration mechanism of the strength of the fabrics by L-cysteine pre-treatment and enzymatic cross-linking modification treatment.The results show that the felting shrinkage rate of wool fabric treated with L-cysteine decreased from 18.67%to 6.84%,but the loss of breaking strength is 34.77%in the warp direction and 32.81%in the weft direction,and the increase of breaking elongation is 13.18%in the warp direction and 19.88%in the weft direction.After cross-linking wool fabrics with laccase-catalyzed ferulic acid,the breaking strength is repaired by 14.21%in the warp direction and 13.54%in the weft direction,and the felting shrinkage rate is 6.49%,which meet fabrics’anti-felting shrinkage requirements,and the breaking strength is repaired effectively,realizing the enzymatic low-damage anti-felting shrinkage treatment of wool.
