Since the 1990s, China has developed rubbing fastness enhancers. After decades of development, progress has been made. Although all major domestic auxiliary auxiliaries’ manufacturers sell their products on the market, they still lack a full range of rubbing fastness enhancers. The wet rubbing fastness of cashmere fabrics is significantly improved, and there is no selectivity for dyes, which affects the feel of the fabric. Very small, no need to adjust the pH value of the working fluid in use.
Certain rubbing fastness enhancers on the market are only suitable for fabrics dyed with reactive dyes.
