Claims
- 1. A continuous, integrated, high speed process for making a multifilament carpet yarn having a very high degree of filament intermixture, the process comprising the steps of:
- (a) forwarding an undrawn multifilament carpet yarn; and
- (b) drawing the yarn until the elongation of the filaments has been reduced to an acceptable level for end use in carpeting applications, the drawn yarn having a denier between 2000 and 4000, the drawn filaments each having a denier between 18 and 35; and
- (c) crimping the drawn filaments with a jet crimping means; and
- (d) over-feeding the yarn to an intermixing jet, the degree of over-feeding being between 1% and 10%,; an
- (e) intermixing the drawn, textured yarn in the intermixing jet, the intermixing jet creating a degree intermixing of the filaments whereby a standard deviation of less than 6.0 results upon conducting a Standard Yarn Streak Potential Test; and
- (f) taking up the textured, interlaced yarn at a speed of at least 800 meters per minute.
