The effect of single-yarn twist and ply to single-yarn twist ratio on the evenness, hairiness and abrasion resistance of two-ply cotton yarn has been studied. The hairiness of two-ply yarn decreases as either the single-yarn or ply twist increases. The rate of reduction in hairiness with respect to twist is more for the single-yarn twist than for the ply twist, particularly for the finer two-ply yarn. Variation in hairiness decreases as the ply twist increases. Yarn-to-yarn abrasion shows a different trend as compared to yarn-to-emery abrasion at a low ply twist level. Two-ply yarn with 3/4 of the single-yarn twist shows the highest abrasion resistance in both yarn-to-yarn abrasion and yarn-to-emery abrasion. The abrasion resistance of the two-ply yarn depends on both single-yarn twist and ply twist. Single-yarn twist and ply twist have a more influential effect on the yarn-to-yarn and yarn-to-emery abrasion resistances respectively of cotton two-ply yarns.
