Polyester: it is a kind of fiber-forming polymer pet, which is prepared by esterification, transesterification and polycondensation of polyethylene terephthalate (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) as raw materials. It is a fiber made by spinning and post-treatment.

Polyester: high strength and toughness. The short fiber strength is 2.6 ~ 5.7cn/dtex, and the high strength fiber strength is 5.6 ~ 8.0cn/dtex. Because of its low hygroscopicity, its wet strength is basically the same as that of dry strength. Its strength is 4 times higher than that of nylon fiber and 20 times higher than that of viscose fiber.

There is no warp and weft in non-woven fabric, so it is easy to cut and sew, and it is light and easy to shape, so it is very popular with handicraft lovers. It has the characteristics of short technological process, fast production rate, high output, low cost, wide application and many sources of raw materials
