Abstract
A method of false twist texturing a synthetic yarn as well the thus-produced crimped yarn. In the method, the yarn is irregularly drawn in a draw zone on a draw pin and subsequently textured in a false twist zone. As a result of the irregular drawing, an open and a closed combination of filaments is alternately produced in the crimped yarn, thus creating a crimped yarn, which exhibits a thin-thick effect.
