Product Details

PBT (Polybutylene Terephthalate) fiber is a new polyester fiber came out in 1970s, it initially attacked people as a engineering plastics with excellent property. PBT fiber not only has PES' durability, dimentional stability and wet state tenacity, and nylon' s soft hand feel and abrasion resistance, but also has better dyeability than polyester and nylon, it can be dyed in normal pressure.

The characteristics of PBT yarn is it has super elasticity, its elastic recovery is much better than polyester yarn and slightly better than nylon yarn; It is dyeable in boiled water temperature, under normal pressure, and the colour fastness is high.

Advantages of PBT Yarn.

Compared with PET yarn (or ordinary polyester yarn), the advantage of PBT filament yarn is better elasticity. It is called "high elastic yarn" or "high elastic yarn". In addition, it has better dyeability than ordinary polyester yarn, which requires lower temperature and pressure during the dyeing process.

PBT yarns are a unique category of yarns that take advantage of the advantages of the polymer polybutylene terephthalate. This yarn helps create high-comfort garments, carpets and automotive fabrics. The fabric provides extra comfort and seamless movement. This innovative yarn ensures a comfortable microclimate around the body. The finished product made of yarn has good air permeability, high elasticity and good color absorption. Due to low water absorption (approximately 0.4% of H2O), PBT yarns are sweat-resistant and their elasticity is not affected when exposed to moisture.

It is also available as elastic and non-elastic yarns with high stretch and superior elastic recovery. These properties are the result of a multi-dimensional bulking process that is not only linear, unlike ordinary elastic yarns.

Fabrics made from this fiber can be ideal for breathable and comfortable intimate clothing, even with PBT content up to 30 to 35 percent. This has helped the fashion industry create versatile designs and countless clothing styles for the finished product.
