Introduction：
Polyester fiber, commonly known as "polyester". It is a synthetic fiber obtained by spinning a polyester obtained by polycondensation of an organic dibasic acid and a diol, and is referred to as a PET fiber. It is a polymer compound and is the first large-sized synthetic fiber. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery ability. It is durable, wrinkle-free, non-sticky and non-sticky.
Spinning.
The polyester chips are dried, melted, and can be used for spinning, preparing polyester films, polyester bottles, and the like. During the melting process, the moisture contained in the slice can cause the polyester to hydrolyze and affect the spinning performance and fiber quality. Therefore, it must be dried before spinning to reduce the water content of the slice to less than 0.01%. The cooled strands are classified into polyester filaments and polyester staple fibers according to different processing techniques.
2.polyester short wire.
When spinning short fibers, a plurality of lines are brought together, and after being wet, the oil falls into a silk drum. The finished product is obtained by a process such as bundling, stretching, crimping, heat setting, and cutting.
3. Polyester filaments.
The decomposition resistance is strong, and the strength and elongation of the fiber are slightly lower. Suitable for blending with cotton, wool, etc., the fabric has better elasticity, hand feeling, wrinkle resistance and pilling resistance, but the strength and wear resistance are poor.
