Abstract: A process for manufacturing spaced dyed yarn for use with tufted or pile carpet including applying one or more colors of dye to one or more yarns in a predetermined spaced relation to form a colorized yarn having a predetermined color pattern.

Abstract: The present invention is an apparatus and method of making yarn for carpet that exhibits a high degree of color pop. More specifically, in one aspect, the present invention comprises an apparatus and method that comprises supplying a plurality of yarns, false-twist the plurality of yarns, and passing the consolidated yarn through a downstream entangling assembly to tack at least a portion of the consolidated yarn. Another aspect of the present invention passes at least one of the plurality of yarns through one of a plurality of second entangling assemblies positioned upstream of the false-twist apparatus.

Abstract: In conjunction with a heat-set apparatus for carpet yarns which incorporates a plenum chamber having a porous upper surface in combination with a forced draft system for recirculating the heating medium throughout the length of the heat-set chamber, an improved design of the plenum chamber and the distribution of the medium to compensate for a temperature gradient which has heretofore existed in the heat-set chamber resulting from the introduction of cooled yarn into the chamber. Such temperature gradient has been the cause of dye streaking which occurs when the yarn is subjected to relatively cooler temperature adjacent to the entrance to the heat-set chamber when the machine is stopped.
