ABSTRACT:
A composite filament yarn made by plying untexturized cellulose acetate yarn with polyamide or polyester yarn is made more coherent by false-twist texturizing it. The increased coherence prevents bunching of the acetate yarn during knitting and so the associated shade variation is avoided. The acetate yarn is spun-dyed and the polyamide or polyester yarn is package-dyed after pre-texturizing. The acetate and synthetic yarns may be dyed to matching shades.
