What are Polyester Staple Fibers?

Polyester Staple Fibers or PSF are short-length textile fibers produced from polymer polyester. The manufacturing of synthetic fibers PSF involves cutting continuous polyester filaments into short prepared lengths which can be spun into slivers or blended with cotton, wool and other natural spun yarns. Wrinkle and shrink resistant PSF is often preferred in garments, household upholstery and industrial products due to its ability to withstand a range of mechanical forces, long service life, and strength.
How is polyester staple fiber produced?
Producing polyester staple fiber (PSF) requires individual steps that are appropriate for the particular technology to achieve the required reproducibility, quality standards, and functional characteristics of the final product. It all starts with Polyethylene Terephthalate (PET) as the product of PTA and MEG’s chemical reaction. PTA and MEG can be obtained via polymerization. Once formed, molten PET undergoes spinneret extrusion to create long continuous filaments.
Uniformity is critical in cooling and solidifying the filaments, which must happen rapidly. The filaments are then drawn to improve their tensile strength as well as their molecular orientation. MD PET filaments are further crimped in order to increase their elasticity and enhance the fabrics ability to blend with other materials. The crimped fibers are then cut into specific lengths which range from 1.5 to 15 deniers depending on their use. Once collected, the fibers are baled and packaged for production in textiles and other industries. Technology and scaling efficiencies improve with time providing greater control over fiber properties such as denier, luster and dyeability which guarantee high performance in end-use applications.
