Polyester staple fiber can be spun alone, or can be blended with cotton and other types of cotton type fiber or staple fiber into yarn. The products are mainly used in cotton spinning industry, spinning alone or mixed with cotton, viscose fiber, hemp, wool, vinylon, etc. The yarn obtained is mainly used for clothing weaving, and can also be used for home decoration fabrics, packaging fabrics, fillers and warm materials.

The primary fiber (winding filament) of polyester staple fiber has low strength, large elongation, high thermal shrinkage and poor hand feeling. Therefore, in order to enhance the practicality (applicability) of polyester staple fiber and eliminate static electricity as much as possible, it is necessary to carry out post-processing of polyester staple fiber.

The post-processing process of polyester staple fiber mainly includes bunching, drawing, oiling, crimping, heat setting, cutting and packing.

Cluster: Preparation;

Draft: improve the degree of orientation; Strength increases and elongation decreases; Thermal shrinkage rate decreased;

Oiling: spinning, textile processing requirements;

Crimp: increases adhesion; Improved hand feel;

Heat setting: improve crystallinity; The thermal shrinkage rate decreased and the hand feel improved; Strength increases and elongation decreases;

Cutting and packing: Product specifications.
