PBT fiber is the abbreviation of polybutylene terephthalate fiber. It is a kind of polyester fiber made by melt spinning, which is a linear polymer condensed by high purity terephthalate (PTA) or dimethyl terephthalate (DMT) and 1, 4-butanediol esterification.
Produced by melting spinning-PBT fiber:
1, especially suitable for production of swimming suits, pantyhose, training clothes, gymnastics clothes, bodybuilding clothes, tennis clothes, dance tights, elastic jeans, ski pants, stockings, bandages for medical applications and other high elastic textiles.
2. PBT and PET composite fibers have fine and dense three-dimensional crimp, superior resilience, soft feel and excellent dyeing properties, which are ideal raw materials for wool and down imitation and comfortable to wear.
3. The filament of PBT fiber can be used after deformation processing, while the staple fiber can be blended with other fibers, and can also be used for making elastic denim with core yarn.It can also be used for making and weaving wool-like fabrics.
4. If PBT fiber is used to make porous insulation flocs, it has washable, soft, breathable, light and thin tufted carpet produced by PBT fiber, which feels like wool carpet.Bristle wire can be used as toothbrush wire and so on.
