Pop Soy Fiber Textile Protein Fiber 1.5D 38MM For Spinning Or Filling Quilt

Soy Fiber: Soy protein fiber belongs to the category of regenerated vegetable protein fiber. It uses food-grade soybean protein powder as raw material, and uses bioengineering technology to extract globulin in protein powder. By adding functional additives, it is linked to polymers such as nitrile groups and hydroxyl groups. Branching, copolymerization, and blending are used to prepare a certain concentration of protein spinning solution, and the spatial structure of the protein is changed, and spinning is carried out by wet spinning. Soybean fiber has a soft feel like cashmere, a soft luster like silk, and has excellent properties such as better warmth retention and skin-friendly than cotton. Known as "healthy and comfortable fiber in the new century" and "good fabric for skin".
