What is the purpose of acrylic yarn scouring?

The main purpose of acrylic yarn scouring is to remove impurities in the fiber and improve the water absorption and permeability of the fiber, which is conducive to the subsequent printing and dyeing processing. In cotton fiber, in addition to cellulose, there are a large number of cellulose co-organisms. Most of these co-organisms are water-repellent. They form a water-repellent film in the cell wall of cotton fiber, which seriously affects the water absorption and permeability of the fiber. Removing these co-organisms and other impurities through the scouring process can make the fiber have good water absorption and permeability, ensure that dyes and auxiliaries can penetrate smoothly into the fiber, and improve the printing and dyeing effect and product quality.
