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.
Claims20
A process for producing an effect yarn comprising:
- (a) providing an unmixed yarn bundle comprising a plurality of continuous filament singles yarns;
- (b) entangling said continuous filament singles yarns of said unmixed yarn bundle to thereby form an entangled yarn bundle;
- and
- (c) twisting said entangled yarn bundle in a twist jet assembly having a first twisting jet and a second twisting jet so as to twist said continuous filament singles yarns of said entangled yarn bundle about each other in alternate S-directions and Z-directions to thereby produce an effect yarn comprising a plurality of S-direction twist sections, a plurality of Z direction twist sections, and a plurality of non-twisted entangled sections interspersed between said S direction twist sections and said Z direction twist sections,
- wherein the average length of said non-twisted entangled sections is greater than the average lengths of said S-direction twist sections and said Z-direction twist sections.
An effect yarn comprising a plurality of S-direction twist sections, a plurality of Z-direction twist sections, and a plurality of non-twisted entangled sections interspersed between said S-direction twist sections and said Z-direction twist sections,
- wherein the average length of said non-twisted entangled sections is greater than the average lengths of said S-direction twist sections and said Z-direction twist sections.
