Polyester staple fiber is a kind of chemical fiber. Fiber length about 38mm, fineness 1.5D. chemical fiber according to chemical composition is divided into polyester, acrylic, chlorylon, spandex, Vinylon, polypropylene, arylon and other classes. Morphology is divided into filament, medium and long fiber (general length 64mm mostly), short fiber (38mm mostly). 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.

In general, polyester short fibers can be divided into three categories: large/medium/small chemical fibers;
Large chemical fiber: This is a kind of polyester short fiber spun by melt direct spinning or PET slice spinning, it is characterized by bright color and strong stability of the fabric, fabric defects are relatively few.

Chemical fiber: The difference between it and large chemical fiber is that it does not use the melt direct spinning process but all through PET slicing or PET back spinning, and the price and quality of chemical fiber are between large chemical fiber and small chemical fiber. Some factories produce such fibers in large quantities in order to ensure fabric quality and save costs.

Small fiber: It will only use the PET re-spinning process, and the price and quality are relatively low, and it is often used to produce fabrics that have low quality requirements for fabrics or accessories (fillers).

Hubei Botao Synthetic Fiber Co., Ltd. was established in October 2000, specializing in the production and sales of polypropylene staple fiber, polyester staple fiber, composite fiber, polylactic acid staple fiber, the products are mainly used in non-woven fabrics, automotive interior, geotextiles, carpets, filtration and other industries.
