In 1941, JR Winfield and JT Dickson of the United Kingdom 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 Denier Polyester Fiber with the trade name Dacron. Subsequently, polyester fiber has developed rapidly in countries all over 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.
