Abstract
Systems and methods for producing BCF yarns include providing at least one color enhancement method for enhancing the color and/or hue of at least one of the N bundles of filaments. The color enhancement methods include tacking one or more of the bundles of spun filaments prior to and/or during drawing, texturizing one or more bundles of spun filaments individually from the other bundles of spun filaments, providing intermediate tacking of at least one bundle of texturized filaments and feeding the tacked and texturized filaments to a mixing cam for positioning tacked and texturized bundles relative one to the other before reaching the final tacking device, or combinations thereof.
Claims25
A method to produce a BCF yarn comprising:
- A. providing N bundles of spun filaments, N being an integer of 2 or more;
- B. partially elongating the spun filaments of said N bundles of spun filaments;
- C. individually tacking at least a first of said N bundles of partially elongated spun filaments;
- D. drawing the spun filaments of said N bundles of tacked and partially elongated spun filaments to a final denier per filament;
- E. texturizing said N bundles;
- and
- F. performing a final tacking of said N bundles of spun filaments to provide a BCF yarn.
A BCF yarn spinning system comprising:
- A. a plurality of spin plates for spinning N bundles of spun filaments, N being an integer of 2 or more;
- B. at least one final drawing device to elongate said spun filaments of said N bundles of spun filaments to a final denier per filament;
- C. at least one texturizer to texturize said N bundles of elongated spun filaments;
- D. a final tacking device to tack said N bundles of texturized spun filaments to provide a BCF yarn,
- wherein said system is further configured to initially draw said spun filaments of at least one of said N bundles of spun filaments upstream of an initial tacking device upstream of said at least one final drawing device to tack said spun filaments of at least one of said N bundles of spun filaments after or during the partial elongation of the N bundles of spun filaments.
