The development history of polyester fiber

In 1941, British J.R. Winfield and J.T. Dixon first successfully developed polyester fiber in the laboratory using terephthalic acid and ethylene glycol as raw materials, and named it Terylene. In 1953, the United States produced polyester fiber with the trade name Dacron. Subsequently, polyester fiber developed rapidly in various countries around the world. In 1960, the world output of polyester fiber surpassed polyacrylonitrile fiber, and in 1972 it surpassed polyamide fiber, becoming the largest variety of synthetic fiber.

It refers to the general name for fibers made from polyester produced by polycondensation of various diols and aromatic dicarboxylic acids or their esters.

Since polyethylene terephthalate fiber is its main variety, it is commonly called polyester fiber to refer to this fiber. This type of fiber has a crisp appearance and good thermal stability, but has slightly poor hygroscopicity. They are mainly used to make various clothing items, bedding, interior decoration items, etc.; individual varieties such as polyethylene 2,6-naphthalate fiber are mainly used in industry.

Polyester fiber refers to the general name for fibers made from polyester produced by polycondensation of various diols and aromatic dicarboxylic acids or their esters. Specific varieties are: polyethylene terephthalate fiber (PET), polybutylene terephthalate fiber (PBT), polytrimethylene terephthalate fiber (PTT), polyterephthalate-1 , 4-cyclohexanedimethyl fiber (PCT), poly-2,6-ethylene naphthalate fiber (PEN), and a variety of modified polyester-based fibers.
