Do you know what the raw material of polyester staple fiber is? I don't know how much you know about it, but I will tell you about it today.

Polyester staple fibers are short fibers obtained by spinning, drawing and cutting polyester (PET) produced by polymerizing PTA and ethylene glycol in a molten state. Since entering my country in the 1970s, due to its wide range of uses and low prices, the market has grown rapidly and has become an important raw material for textile, clothing, home textiles and other industries.

According to different classification standards, polyester staple fibers can be divided into different categories. According to raw materials, it can be divided into virgin polyester staple fiber and recycled polyester staple fiber. The virgin polyester staple fiber is made of PTA and ethylene glycol after polymerization, spinning and cutting. , made after spinning and cutting, commonly known as "small chemical fiber".

Polyester staple fibers can be divided into three categories according to different uses: spinning, filling, and non-woven. Spinning yarn is the most important use of polyester staple fiber, including cotton spinning and wool spinning. Cotton spinning and wool spinning refer to spinning with cotton-type and wool-type fibers, respectively. The amount of cotton spinning is relatively large, mainly including polyester pure spinning, polyester-cotton blended, polyester-viscose blended and the production of polyester staple fiber sewing thread. Wool spinning mainly includes polyester nitrile, polyester wool blending and making blankets.
