What is polyester staple fiber made of

What is polyester staple fiber? Polyester staple fiber is a fiber obtained by spinning polyester (ie, polyethylene terephthalate, referred to as PET, polymerized by PTA and MEG) into tow and cutting it. PET is in the form of rice grains or flakes, with various varieties and colors (usually, the main component of beverage bottles we contact a lot is polyester, and it is sliced, generally through the two main processes of pre-spinning and post-spinning, to produce polyester shorts. According to different needs, polyester staple fibers of different specifications can be cut into different specifications in the post-spinning process, generally 4D-22D, and can be divided into two-dimensional and three-dimensional according to their curling conditions). 75% of the polyester is used for chemical fiber, and polyester staple fiber and polyester filament are manufactured according to the requirements of the textile industry.

Characteristics of polyester staple fiber

1. Wear resistance

The abrasion resistance of polyester is second only to nylon and ranks second among synthetic fibers.

2. Water absorption

​​Polyester has low water absorption and moisture regain and good insulation performance, but due to low water absorption, large static electricity generated by friction, and poor dyeing performance.

The use of polyester staple fiber

The products are mainly used in the cotton spinning industry, spun alone or blended with cotton, viscose, hemp, wool, nylon, etc. The resulting yarns are mainly used for clothing weaving, and can also be used for home improvement fabrics, packaging fabrics, filling materials, and Thermal material.
