In comparison with polyester yarn, polyester staple fiber generally have two major differences in terms of their processing manufacturing process and the final form they take:

First, polyester staple fiber is mainly used for cotton textile processing, while polyester yarn is mainly processed by weaving or knitting;

Second, polyester staple fiber is mainly spunbonded, and polyester yarns are spun at high speed.

Although there are two major differences between polyester staple fiber and polyester yarn, the forming mechanism of PET fiber has been studied and evaluated. The basic principles of spinning, stretching and setting are the same. There are alternative polyesters. The potential for yarns.
