Process for making multicolor multifilament non commingled yarn
First Claim
1. A process comprising the sequential steps of:
- (a) 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;
(b) 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;
(c) 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
(d) texturing the bundle without commingling to make a nontwisted, noncommingled singles yarn displaying two distinct unblended colors.

15. A process comprising the sequential steps of:
-
(a) supplying to a draw roll first multifilament feed yarn having a total denier of 300 to 1300 and a denier per filament of 10 to 30 and second multifilament feed yarn having a total denier of 300 to 1300 and a denier per filament of 10 to 30, which feed yarns are differently colored or colorable with respect to each other, in a separated side-by-side parallel relationship in independent paths through a series of guide pins; (b) drawing the first feed yarn and the second feed yarn at the draw rolls while keeping the first feed yarn and the second feed yarn in a relatively parallel relationship and separated from each other by passing each feed yarn over grooved separator rolls corresponding to the draw rolls and which have separate groove paths for each yarn; (c) making a bundle from the first drawn feed yarn and the second drawn feed yarn by simultaneously in a single fluid jet 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 (d) texturing the bundle in a thermo-pneumatic stuffer box without commingling filaments between the bundles to make a nontwisted, noncommingled singles yarn. - View Dependent Claims (16, 17, 18)
