Abstract
A yarn is provided which has zero twist and random lengths of tightly entangled fibers as nodes having substantially zero twist and comprising an average of about 20%-70% of a representative length of yarn, said nodes having a retentivity of at least 75% and alternating with random lengths of substantially unentangled asymmetrically splayed fibers in intervals having an average length of about 3-12 mm. A fraction of the fibers in the yarn can be broken to provide effect yarns.
