Using biobased source sorona PTT, it endows fibers and fabrics with a soft hand feel, comfortable stretching and recovery, easy dyeing at room temperature and pressure.

This biobased PTT+PET two-component elastic yarn with a uniform spring-like structure, it has the best elasticity and dyeability among non-spandex elastic fibers, with long-lasting elasticity and good recovery.As well as natural stiffness and wrinkle resistance characteristics. It can be widely used in various clothing fabrics.

PTT+PET two component yarn is among the best in the market for two-component composite elastic fibers, belonging to the high-tech new synthetic fiber series. Its working principle is that the thermal shrinkage performance of different components in the fiber is different, and it has a permanent main spiral structure. To put it simply, it is coiled like a telephone wire, has permanent elasticity like a spring, and can be easily processed, providing many advantages for the fabric.
