Abstract
This paper outlines why cellulose triacetate, which has been known for 90 years, has only recently become a fiber-forming material of considerable commercial interest. After giving a brief historical background, it describes the structure of triacetate as developed by heat treatment and the utilization of heat treatment for the improvement of fiber and fabric properties. It further presents data on the durability of triacetate yarns and fabrics when exposed to various service conditions and outlines the possible use in so- called "ease-of-care" and "wash-and-wear" fabrics and garments.
