ABSTRACT:
A continuous, high speed (greater than 800 meters per minute) process and apparatus enable the production of a multifilament carpet yarn having a degree of filament intermixture high enough so that a standard deviation of less than 6.0 results upon conducting a Standard Yarn Streak Potential Test, as described herein. The apparatus and process allow the production of a multicolored carpet yarn which exhibits a reduced tendency to streak and an increased retention of tip definition.
