Due to this kind structure, bi-component filament has better elasticity besides the good properties of PTT. Compared to Spandex core-spun yarn or fascinated yarn, PTT/PET bi-component filament saves the procedure and have the better dyeing performance.
这种自身的特殊结构，使PTT／PET双组分长丝不仅拥有PTT的优良性能，还具有更加优良的弹性性能，可以与弹性纤维媲美，同时省去了目前弹性织物常采用的氨纶包芯纱、包缠纱所需要的包纱处理工艺，而且染色性能优于氨纶。
