ABSTRACT:
A method for producing ingrain spun-like yarn simulating a blended staple yarn is described wherein continuous filament yarn is produced which has characteristics similar to blended staple spun yarns. Fabrics made from the yarns described herein provide a fine grained heather appearance without the normal moire or plaiting effect seen in previous ingrain continuous filament yarn fabrics. The unusual continuous filament yarn described herein is made by a texturing process which involves the combination of two or more differently dyeable continuous synthetic yarns which are false twist textured followed by overfeeding to an air bulking means. The preferred method utilizes false twist texturing of synthetic filaments such as polyester, nylon, cellulose acetate or cellulose triacetate and mixtures thereof wherein two differently dyeable yarns are combined 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.
