Polyester staple Fibers are a chemical fiber. The fiber length is about 38mm, and the fineness is 1.5d. Chemical fiber is divided into polyester, acrylic, germline, spandex, vivine, polyester, aramid, etc. according to chemical components.Divided into filaments from the shape, medium and long fibers (usually 64mm in length), short fibers (38mm). Polyester staple Fibers can be spinned separately, or a cotton-type fiber or staple bristles such as cotton. The products are mainly used in cotton textile industries, separate spinning or cotton, viscose fibers, hemp, hair, and vivinal, the resulting yarn is used for clothing weaving, and can be used for home improvement fabrics, packaging fabrics, fillers and Warm material.

Because the germline of the  polyester staple fiber (winding wire) is low, the strength is large, the heat shrinkage is high, the hand is poor; therefore, in order to enhance the practicality (applicability) of polyester short fibers, it is necessary to remove static electricity as much as possible. The fibers are processed. So what is the process of post-processing of  polyester staple fibers?

The post-machining step of polyester staple fibers is mainly a combination, drafting, oil, curling, heat setting, cutting and packaging.

Bunch: Preparation;

Tropion: Improve the degree of orientation; the strength is increased, the elongation is lowered; the heat shrinkage decreases;

Oil: spinning, textile machining requirements;

Curly: increasing the bustling force; improve the feel;

Heat type: increase the crystallinity; the heat shrinkage rate is lowered, the hand is improved; the strength is increased, and the elongation decreases;

Cut off and packaged: product specifications.

The rear processing step of  polyester staple fiber is indispensable, otherwise it will bring a certain negative impact on the polyester finished product. Therefore, for the quality and corresponding performance of the finished product, the polyester short fiber processing step should be completed one by step.
