摘要：
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.
