Bi-component polyester
filament Yarn is made from two polyester fibers with different properties. mainly
includes the following products:
1)ITY (BSY) composed of

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
Features:
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.
Note:
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
