Several sources of information seam to confirm the notion that staple processing machinery doss not mix single fibers in a random fashion. There is, rather, a tendency for fibers to remain together in dusters of site ranging from about 15-30 fibers (or more) in single-carded sliver down to 2-6 in yarns. Three-cylinder carding appears to reduce the cluster size directly to about 2-4.nDrafting apparently reduces the clustering as evidenced by blend distribution along the strand length. The actions of doubling and condensing alone cannot accom¬plish this, but seem to randomize single fibers within cross-sections.
