Continuous protease method for shrink proofing finishing of wool fabrics
Aiming at the severe pollution caused by the existing shrink proofing treatment of wool fabric by chlorination method,the protease Savinase 16L and the substrate activator LKZ-630 were used to form a protease-catalyzed system to carry out the shrink proofing finishing of wool fabrics in the way of multiple padding.The results show that the total area shrinkage of wool fabrics was reduced from 14.6%to 1.0%after protease treatment,which met the requirement of machine-washable.The scales of the treated wool became thinner and smoother,and the warp-breaking strength was reduced by 14.63%.In addition,the treated fabrics had good wettability,deep dyeing,and a soft hand feel.
