Abstract: Systems for producing M yarns, wherein M ≥ 1, include N extruders, M spin stations, and a processor, wherein N > 1. Each extruder includes a thermoplastic polymer having a color, hue, and/or dyability characteristic, which are different from each other. Each spin station produces one yarn comprising at least one bundle of filaments. Each spin station comprises at least one spinneret through which filaments are spun from at least two molten thermoplastic polymer streams received by the respective spin station and N spin pumps upstream of the spinneret for the respective spin station. Each spin pump is paired with one of the N extruders. The processor is in electrical communication with the N*M spin pumps and is configured to adjust the volumetric flow rate of the polymers pumped from each spin pump to achieve a ratio of the polymers to be included in each M yarn.

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.
