Abstract
This invention relates to a new cable-twisting process for making yarns suitable for use in carpets. The process involves cable-twisting together two component yarns. At least one of the component yarns comprises two singles yarns co-twisted but not cabled together. The singles yarns may be differentially colored to provide the resulting multi-colored cable-twisted yarn with good color separation and vividness.
Claims13
A process for cable-twisting together two component yarns, including the steps of feeding at least one singles yarn from a creel to form a creel component yarn and feeding the creel component yarn onto a rotating disc, whereby the yarn emerges from the disc and forms a balloon, the improvement comprising:
- a) feeding at least two singles yarns from a bucket and co-twisting, but not cabling, the yarns together to form a co-twisted bucket component yarn;
- and
- b) feeding the co-twisted bucket component yarn to a yarn guide eyelet, where the creel component yarn emerges from the balloon and wraps around the co-twisted bucket component yarn to form a cable-twisted yarn comprising two component yarns.
