Effect of Laccase-Catalyzed Ferulic Acid on Repairing Felting Shrinkage Damage of Wool
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 direc-tion and 19.88％in the weft direction.After cross-linking wool fabrics with laccase-catalyzed ferulic acid,the breaking strength is repaired by14.21％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.
