Introduction to the basic situation of polyester staple fiber

Polyester staple fiber (abbreviated as "staple fiber") is a fiber obtained by spinning polyester (ie polyethylene terephthalate, abbreviated as PET, polymerized by PTA and MEG) into tow and cutting. polyester staple fiber (English name Polyester staple fiber, PSF for short) is mainly used in the textile industry, spinning alone or blended with cotton, viscose fiber, linen, wool, etc. The resulting yarn is mainly used for garment weaving, and can also Home improvement materials, non-woven fabric industry, filling materials and thermal insulation materials.

Polyester is generally milky white with mercerizing. Conventional polyester has a smooth surface, high crystallinity, and a density close to wool. The abrasion resistance of polyester is second only to nylon, ranking second among synthetic fibers, and its moisture regain is low. Good insulation performance, but due to low water absorption, high static electricity generated by friction, poor dyeing performance.

The main specifications of polyester staple fiber are: semi-dull natural white 1.56dtex*38mm (standard specification); semi-gloss 1.33*38mm; bright 1.33*38mm; 1.56*38mm spunlace special specifications; 2.22/2.78*51mm medium and long fibers.

The polyester staple fiber units are:

1. Denier (D): It is a method of expressing the fineness of chemical fibers, which refers to the weight of a 9000-meter-long fiber in grams, 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.;

2. Dtex (dtex): Dtex is the international unit of fiber denier. The weight of a 10,000-meter fiber is in grams. The larger the grams, the thicker the yarn or fiber. Such as 1.56dtex, 1.33dtex, 2.22dtex, etc. Conversion method of the two: dtex (dtex)=1.11*denier (D), such as: 1.56dtex=1.4D, 1.33dtex=1.2D, 2.22dtex=2D.

China is a major producer and exporter of polyester staple fiber, with a production capacity of 64% of the world, mainly distributed in coastal areas such as Jiangsu, Fujian and Zhejiang. The downstream is mainly used in the textile field. The largest consumption field is spinning, which accounts for 65% of consumption; other consumption includes non-woven fabrics, fillers, sewing threads, etc.
