Abstract:

This paper introduced the degradation mechanism and research status of cellulose acetate biodegradation, hydrolysis, and photolysis. The factors that affect the degradation rate of cellulose acetate were explored. Based on the current studies, the molecular structure of cellulose acetate was the main factor that affects the degradation rate of cellulose acetate. The physical modification, chemical modification, and plasticizing modification affected the degradation performance of cellulose acetate through changing the molecular structure of cellulose acetate. Finally, the application fields of acetate fiber were summarized and its prospect was analyzed.

Key words: cellulose acetate, hydrolysis, photolysis, biodegradation, modification
