Abstract
Method and apparatus for making a variegated multicolor fabric by knitting or weaving from a yarn spun from decorative mass of fiber fluff made from staple fibers arranged in continuous form of discrete streams of different uniform colors. The streams are brushed or carded so as to only partially intermix fibers of at least two different colors. The accumulated fibers removed from the card clothing form a pillow batt or roving having a streaked appearance with only a partial intermixing and blending of the streaks of one color with those of another. These are slightly further worked into a final fluff product having randomly dispersed bands, streaks and/or islands of one color softly merging into another color to produce a decorative randomized and interrupted candy-cane like appearance in the cotton-candy like mass of final fiber fluff for spinning into yam for making the fabric.
