A review of postspinning processes that effect yarn hairiness focuses on preparation for weaving and spinning, including yarn storage; processes that impart hairiness deliberately; winding and rewinding; doubling, twisting, and retwisting; singeing and warping; and sizing (composition and application of size, control of the amount of size absorbed, and sizing efficacy). Storage can increase yarn hairiness by as much as 20 percent. Mechanical treatments increase the hairiness of yarns when specified. Winding and rewinding increase yarn hairiness, the extent to which depends on fiber type. Twisting can improve yarn hairiness, particularly in short fiber yarns, and this improvement depends on the twisting speed and the number of twists. Increases in hairiness can result in tension differences between yarns during warping. Sizing warp yarns reduces hairiness and improves strength for weaving and knitting. 129 refs.
