How Is Acetate Fiber Bundle Produced

Raw material preparation: The main raw materials include wood pulp, acetic acid, acetic anhydride, sulfuric acid, acetone, etc.
Acetylation treatment: Wood pulp is acetylated to form cellulose acetate flakes.
Dissolution and spinning: Dissolve cellulose acetate flakes in acetone and spin them into fiber strands using a spinning machine.
Bundle and Curl: The fiber strands are stretched by bundle rollers and then curled and deformed by a curling machine.
Drying and recycling: The curled fiber bundles are dried in a dryer while recovering acetone.
Packaging: Finally, pack the dried fiber bundles into finished products.
