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 thence 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.
Claims11
A continuous filament spun-like yarn comprising a heat set stabilized multifilament synthetic yarn wherein individual filaments are longitudinally in a helical configuration with periodic reversals of extended helix direction along their length, said individual filaments additionally having torque induced kinks and twisted loops in random distribution along the length of said yarn, said yarn being held together as an integral bundle by the intermingling of the respective individual filaments.
