Teijin has developed an advanced highly functional fiber with a lightweight feel and dry to the touch, as well as good washing resistance and sweat-absorbing and quick-drying capabilities. This is a never-seen-before textured yarn with a random cross-sectional shape and deep grooves has resulted in the success of a sweat-absorbent quick-dry fiber with excellent properties. Moreover, the new yarn is highly functional and has an extremely large inter-fiber space that gives it a lightweight feel and dry to the touch.
