ABSTRACT:
A colored yarn is made in an inexpensive manner that allows a wide variety of different colors or hues within the product line, and also allows a wide variety of different effects to be produced including yarns with minimal leather effect, or yarns with a distinct and desired heather effect. A first coarse feeder yarn, e.g. a 1/1 semi worsted yarn, is ring or open end spun with about 2.5 turns per inch. The coarse feeder yarn is dyed, dried, and then cut and opened up into individual fibers about four inches long or less (preferably two inches long or less). The individual fibers are blended with differently colored or hued fibers produced in the same way, and/or with greige or colored staple fibers, to produce a blended composite of fibers. The blended composite is then spun, for example ring spun or open end spun, into a final colored yarn. Rayon fibers may especially effectively and uniquely be utilized, although almost any fiber or mix of fibers can be used.
