The nature of hairs of the two types of yarn has been studied in terms of protruding ends and loops. Silk-nylon core-spun yarns show less number of ends and loops than equivalent silk ring-spun yarns. In both types of yarn, the distribution of loops with respect to different intersecting lengths has been found to be exponential in nature.</span
