product description
It is a graft modifier for silk after degumming and before dyeing and finishing. Since raw silk removes impurities such as pigment, fat, wax, etc. during degumming, there is a weight loss of 20-30% of the degumming amount. The weight gain treatment before dyeing and finishing can not only make up for the weight loss of white silk due to degumming, but also And it can obviously improve the appearance of Baichang silk, and improve the use effect of the corresponding silk fabric.
