PET/PTT composite elastic yarn is a kind of elastic fiber with self-crimping by using the parallel composite spinning technology of PET/PTT composite elastic yarn, which uses the shrinkage difference of PET and PTT components.
It does not need false twisting, and has excellent shrinkage performance, with a curl shrinkage rate of more than 30%;
It has excellent elasticity, which can replace spandex in the field of medium and low elasticity, which is more elastic than PBT and PTT, and more fatigue-resistant;
Good dyeing performance, overcoming the problem of spandex blank space;
Good anti-fatigue and anti-aging properties, and the elasticity will not disappear with time;
Good wrinkle resistance and easy care;
