ABSTRACT:
A method for producing a spun-like yarn simulating a staple yarn is described wherein continuous filament yarn is produced which has characteristics similar to a staple spun yarn. The unusual continuous filament yarn produced is made by a texturing process which involves the crimping of a continuous synthetic yarn followed by overfeeding to an air bulking means and then to heat setting means. The preferred method utilizes false twist texturing of synthetic filaments such as polyester, nylon, cellulose acetate or cellulose triacetate and mixtures thereof with an air bulking jet interposed to act on the false twist textured yarn while it has a high residual torque and subsequently decaying said torque.
