Polybutylene Terephthalate PBT

Swicofil, your expert partner for PBT textured yarns, monofilaments and POY.

Polybutylene terephthalate, abbrevated PBT, belongs to the Polyester family. In the textile applications, it is mainly used because of its elasticity. 

PBT has extension capacities that surpass those of comparable yarns by one third. This highly elastic, friction textured PBT yarn will convince you with its soft, pleasant touch that is ideal for comfort clothing, in particular for sports.

Thanks to its unique recovery properties, PBT fabrics will always return to their original shape even after extreme strain. This ensures comfortable, body-hugging clothing that is ideal to wear for sports activities.

PBT combines high resistance with extraordinary softness. Even after further manipulation, PBT won't lose its suppleness. 

The exceptional light-fastness of PBT is equivalent to that of a normal polyester. And its proven resistance to chlorine and UV rays makes PBT the perfect choice for all types of clothing. And PBT will develop its strengths even when used in combination with natural and other synthetic fibres, thanks, amongst other things, to its 100°C required dyeing temperature.
