Bi-component polyester filament Yarn is made from two polyester fibers with different properties. mainly includes the following products:

1)ITY (BSY) composed of polyester FDY and POY composite spinning

2)SPH is a low viscosity PET and high shrinkage PET composite spinning.

3)M400 by high viscosity of PTT and low viscosity PET composite spinning   

4)T8 is made up of low viscosity PBT and high viscosity PET composite spinning


two components of different types of thermal shrinkage performance, make it produce a permanent curl in the finishing process, thus elastic, also has certain moisture absorption perspiration function.


1. The dyeing temperature and finalize the design temperature is unfavorable and exorbitant, too high will affect the elastic fabric;

2. Try to use in the process of finishing the hydrophilic agent, in order to avoid jam fiber groove, destroying its moisture absorption perspiration function
