A comparative study between the dynamic friction characteristics of compact and siro yarns

This study was conducted to compare the dynamic frictional properties of less-hairy yarns (compact, compact-siro and sirospun yarns) to conventional ring-spun yarns. Due to different surface characteristics affecting the frictional behavior, yarns spun by various spinning technologies differ from each other. Identical yarns of varying parameters including yarn type, yarn count, and strand spacing (for sirospun yarns) were produced from the same cotton roving to eliminate variability in raw material. Yarn-to-yarn friction (µYY), yarn-to-metal friction (µYM) and yarn abrasion characteristics of these yarns were determined by CTT instrument. The results have revealed that spinning method and yarn linear density have significant effects on the frictional and lint shedding features of the yarns whereas strand spacing has a limited influence on the yarn frictional properties
