PBT is the abbreviation for polybutylene terephthalate. PBT high elastic yarn has excellent elastic recovery performance and elastic stability.

PBT is the abbreviation for polybutylene terephthalate. PBT high elastic yarn has superior elastic recovery performance and elastic stability, its elasticity is better than nylon, its chemical resistance is better than spandex, it can be dyed under normal temperature and pressure without a carrier, and it has high color fastness and good dimensional stability. , Anti-pilling, anti-static. And the price is much lower than spandex. The fiber can be widely used in knitted and woven fabrics, and can replace spandex to produce covered yarns. It is used as the fabric for sportswear, swimwear, and casual wear. PBT high-elastic yarn has a wide range of application prospects in the fields of sanitary materials, clothing, etc., and is a new and competitive product in the elastic fiber market in the future.

1. PBT has good durability, dimensional stability and good elasticity, and the elasticity is not affected by temperature.

2. PBT fiber and its products have soft hand feeling, good moisture absorption, abrasion resistance and fiber crimping, tensile elasticity and compression elasticity, elastic recovery rate is better than polyester, and it has special stretchability under dry and wet conditions. Moreover, the elasticity is not affected by changes in the ambient temperature, and the price is much lower than that of spandex fiber.

3. PBT has good dyeing performance, and ordinary disperse dyes can be used for normal pressure boiling dyeing without a carrier. The dyed fiber has bright color, excellent color fastness and chlorine resistance.

4. Has excellent chemical resistance, light resistance and heat resistance.

5. PBT and PET composite fiber has fine and dense three-dimensional crimp, superior resilience, soft hand feeling and excellent dyeing performance. It is an ideal wool-like and down-like raw material, and it is comfortable to wear.

6. Main specifications: 50D, 75D, 100D, 150D, etc.
