The difference between polyester yarn and milk yarn, how to distinguish milk yarn polyester yarn? Polyester fiber is the trade name of polyester fiber in China. Polyester is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and diol. The industrially mass-produced polyester fiber is made of polyethylene terephthalate. There are two types of polyester, one is polyester filament, and the other is polyester staple fiber. After opening, blending, carding, drawing, roving, and spun yarn, polyester staple fiber is spun into polyester yarn.

 

Milk protein fiber uses cow's milk as the basic raw material. After dehydration, deoiling, degreasing, separation and purification, it becomes a kind of cheese protein with linear macromolecular structure; then it is blended with polyacrylonitrile by high-tech means. Cross-linking and grafting to prepare spinning dope; finally, it is formed by wet spinning into fiber, curing, drawing, drying, crimping, setting, short fiber cutting (filament winding). It has excellent safety in use; it has natural antibacterial function, is more resistant to mold and moth than wool and cashmere, has higher strength, is durable and washable, and is easy to store; it is easy to dry after washing, and it can maintain the permanent performance of the product after washing.
