Common Polyester Staple Fiber Polyester Wear Resistance
May 31, 2017

Polyester staple fiber is made of polyester (that is, polyethylene terephthalate, referred to as PET, from PTA and MEG polymerization) re-spinning into the fiber after cutting.

PET is a grain or grain-like, various varieties of different colors (usually we contact a lot of beverage bottles is the main ingredient of polyester, he sliced, usually after the former spinning and spinning two main processes can produce polyester short Fiber, according to different needs, in the spinning can be cut into different specifications of the polyester staple fiber, usually 4D-22D, according to its curly situation can be divided into two-dimensional and three-dimensional two). 75% for the chemical fiber with polyester, according to the textile industry requirements, the manufacture of polyester staple fiber and polyester filament.

Feature editing

Wear resistance: polyester wear resistance after the nylon, in the synthetic fiber ranked second.

Water absorption: polyester moisture regain low, good insulation properties, but because of low water absorption, friction generated by electrostatic, poor dyeing performance.

Use edits

Products are mainly used for cotton industry, separate spinning or cotton, viscose fiber, hemp, wool, vinylon and other blends, the yarn used for clothing weaving, can also be used for home improvement fabrics, packaging cloth, filling materials and Warming materials.

Polyester fibers Synthetic fibers obtained by spinning polyesters made from polycondensation of organic dibasic acids and glycols. Referred to as PET fiber, is the first synthetic fiber varieties. In addition to its biggest advantage is good wrinkle resistance and shape retention, with high strength and elastic recovery. Its fast and durable, anti-wrinkle-free, non-stick hair.

Polyester and natural fiber compared to the existence of low moisture content, poor air permeability, poor dyeing, easy pilling, easy to stain and other shortcomings. In order to improve these shortcomings, take chemical modification and physical deformation methods. Chemical modification methods are: ① added hydrophilic monomer or oligomer polyethylene glycol copolymerization, can improve the moisture absorption rate of fiber; ② add antistatic properties of the monomer copolymerization, can improve the fiber Anti-static and anti-staining performance; ③ adding phosphorus, halogen and antimony compounds to improve the fiber resistance to combustion; ④ lower polymerization degree of polyester spinning to improve the anti-pilling ability; ⑤ and dyes (Such as sulfonates, etc.) to improve the dyeing properties of the fibers. After physical deformation of a variety of profiled polyester, and other polymer composite spinning, coloring polyester, fine denier polyester and high shrink polyester and so on.
