Working principle of cellulose acetate tow

The working principle of cellulose acetate tow mainly includes the following steps:

Raw material processing: The main raw material for cellulose acetate tow is cellulose. Natural cellulose mainly comes from plant fibers such as Mosier bamboo, wood bamboo, and hemp bamboo, while synthetic fibers come from synthetic cellulose, polyester fibers, etc. Firstly, the cellulose raw material is crushed, and then the crushed cellulose is mixed with starch acetate for gelatinization treatment.

Spinning: Inject the sol solution into the cellulose drawing machine, and through processes such as stretching and heating, form slender fiber bundles.

Curling: During the spinning process, curling can be introduced through a stuffing box curling machine, which has a pressure roller suitable for introducing curling into the fiber bundle. The curling is introduced into the fiber bundle through the axial groove surface of the pressure roller.

Drying and sorting: Dry and spin the curled fiber bundles, and finally pack them into storage.
