  • Process for making multicolor multifilament non commingled yarn
    Patent number: 5613285
    Abstract: The process includes the sequential steps of supplying in a separated side-by-side parallel relationship to a yarn drawing apparatus first multifilament feed yarn and second multifilament feed yarn which are differently colored or colorable with respect to each other; drawing the first feed yarn and the second feed yarn in the yarn drawing apparatus while keeping the first feed yarn and the second feed yarn in a relatively parallel relationship and separate from each other; making a bundle from the first drawn feed yarn and the second drawn feed yarn by simultaneously imparting false twist to the drawn first feed yarn and the drawn second feed yarn without commingling the first and second drawn feed yarns; and texturing the bundle without commingling to make a nontwisted, noncommingled singles yarn displaying two distinct unblended colors.
