Study on the Frictional Behavior of Cotton Spun Yarn (Unraveled from Fabrics) after Different Wet Processing Stages

Abstract

Tearing strength of the woven fabric is an important mechanical property which directly decides the fabric serviceability. Yarn-yarn friction, one of the most important factors of fabric tearing strength, is a characteristic inherited from the surface and bulk properties of the interlacing yarns that decides the yarn interaction behavior. In this work, an experimental set-up was fabricated to measure the yarn-yarn friction on an UTM. By using this set-up, a study was carried out with the unraveled yarns obtained from commercial cotton woven fabrics consist of two sets of plain shirting fabrics, with different combinations of warp and weft type, i.e., ring-combed yarn, ring-compact yarn, and one set of plain suiting fabrics made of OE yarn. All these fabrics were processed through standard commercial chemical processing stages and samples were collected after each wet processing stages. It is found that, yarn-yarn co-efficient of friction (μ) of the compact yarn after finishing has the lowest μ, i.e., 0.32 as compared to ring and OE yarn μ of 0.36 and 0.45, respectively. However, after dyeing the μ is highest for all the yarns, i.e., μ of compact, ring and OE yarns are 0.35, 0.40, and 0.52, respectively.
