The production process of acetate fiber tow includes the following main steps:
Raw material processing: The main raw material is cellulose, including natural cellulose (such as mosir bamboo, wood bamboo, hemp bamboo and other plant fibers) and artificial fibers (such as artificial cellulose, polyester fibers, etc.). The cellulose raw material is crushed and mixed with acetate starch ester for sol treatment.
Wire drawing process: The sol liquid is injected into the cellulose drawing machine, and a slender fiber bundle is formed through processes such as stretching and heating.
