PBT fiber is made by melting PBT chips and spinning them. PBT chips used to make PBT fibers are usually called fiber-grade PBT or spinning-grade PBT, and the quality indexes of fiber-grade PBT are somewhat different from ordinary PBT.

Applications of PBT fiber

1、Specially suitable for the production of swimwear, hosiery pants, training clothes, gymnastics clothing, bodybuilding clothing, tennis clothing, dance leotard, elastic jeans, ski pants, stockings, medical applications such as bandages and other highly elastic textiles.

2, PBT and PET composite fiber with fine and dense three-dimensional curl, superior resilience, soft hand and excellent dyeing properties, is the ideal imitation of wool, imitation down raw materials, comfortable to wear.

3, PBT fiber filament can be used after the deformation process, and short fibers can be blended with other fibers, can also be used for core yarn to make elastic labor cloth. Can also be used for weaving imitation wool fabrics

4, if the PBT fiber made of porous insulation flocculent, it has a washable, soft, breathable, thin and light, tufted carpet produced with PBT fiber, feel like wool carpet. Sideburns can be used as toothbrush wire, etc., with good anti-falling hair performance.

Uses: It is used to replace the high-priced polyurethane elastic fiber to make some fabrics and clothing items that require goodelasticity, such as pantyhose, women's underwear, swimming suits, tennis suits and diving suits.
