Polyester staple fiber, referred to as PSF, is a fiber obtained by spinning polyester (that is, polyethylene terephthalate, PTA for short, polymerized from PTA and MEG) and then cutting it into tow. The products are mainly used in the cotton spinning industry, spinning alone or blended with cotton, viscose fiber, linen, wool, vinylon, etc. The obtained yarn is mainly used for textile and clothing, and can also be used for non-woven fabrics, filling materials and thermal insulation materials. .

Main Specifications of Polyester Staple Fiber

The main specifications of polyester staple fiber include semi-dull natural white 1.56dtex*38mm (the benchmark specification, which is the delivery target of listed futures varieties), accounting for 49% of the virgin staple fiber; semi-dull 1.33 dtex *38mm; glossy 1.33 dtex *38mm; 1.56 dtex *38mm special specification for spunlace; 2.22/2.78 dtex *51mm long fiber, etc.

International unit of polyester staple fiber

In the above, dtex (decitex) is an international unit of fiber denier, which indicates the weight of fiber in grams of 10,000 meters long. The larger the number of grams, the thicker the yarn or fiber.

At the same time, D (denier) is also a fineness expression method of a chemical fiber, which refers to the weight in grams of a 9000-meter-long fiber, also known as denier. Usually expressed by D, the larger the D, the thicker the fiber. Such as 1.4D, 1.2D, 2D, 6D, etc. The conversion method of the two is decitex (dtex)=1.11*denier (D), such as 1.56dtex=1.4D, 1.33dtex=1.2D, 2.22dtex=2D.

Application field of polyester staple fiber

Polyester staple fiber is mainly used in three major fields: textile yarn, accounting for 77%, end products are clothing, home textiles, decorative fabrics, etc.; nonwovens, accounting for 17%, end products are wet wipes, masks, etc.; filling used, accounting for 6%, and the end products are winter clothes, quilt pillows, toys, etc.
