Abstract: A process is provided for the manufacture of an effect yarn, such as heathered helix yarns, for use in carpets, floorcoverings, and textile articles. The effect yarns contain patterned alternating sections of twisted multiple singles yarns and sections of entangled multiple singles yarns. More particularly, these effect yarns may comprise a plurality of S-direction twist sections, a plurality of Z-direction twist sections, and a plurality of non-twisted entangled sections interspersed between the S-direction twist sections and the Z-direction twist sections.

Abstract: Processes are provided for the manufacture of color effect face yarns for use in tufted goods. These color effect yarns may exhibit unique color effects and contain a lower overall denier, thereby allowing the production of tufted goods with a greater than normal tuft density per unit area. Consequently, this can result in finer color effects and/or sharper definition of color effects in the tufted goods and expands the design possibilities for such products.

Abstract: Wool-like, synthetic multifilament yarns may be produced with a plurality of primary yarns and at least one secondary yarn. Generally, the primary yarn and secondary yarn may be produced from polyamides. The wool-like multifilament yarns may be produced by: (1) melt-spinning the primary yarns and the secondary yarn; (2) drawing and texturizing the primary yarns and the secondary yarns; (3) entangling the texturized primary yarns and the texturized secondary yarn to form the inventive yarn; (4) optionally subjecting the inventive yarn to heat-setting or heat annealing; and (5) winding the yarn onto a package for distribution. The multifilament yarns may be used to produce floorcoverings.
