Polyethylene terephthalate (PET) is often called polyester. At present, PET fiber is mainly prepared by direct esterification of terephthalic acid (PTA) and ethylene glycol (EG) or by transesterification of dimethyl terephthalate (DMT) and ethylene glycol (EG).
The benzene ring exists in the PET molecule, so it needs to be stretched after the traditional melt spinning, so as to make it rapid crystallization, which can make the fiber orientation and crystallinity is high, and the PET fiber produced from this, has high strength, good elasticity, excellent heat setting performance, good heat resistance, acid and alkali resistance. The disadvantages of PET are mainly due to the tight molecular arrangement and the lack of hydrophilic group, so the dyeing, hygroscopic, antistatic property is poor, and the product is easy to burn.
