Evaluation of the impact of cotton sheath linear density of core spun yarn on the performance of denim fabrics

Abstract

In the textile sector, denim is one of the most iconic woven fabrics. The quality of denim fabric is influenced by several factors. For example, changes in the linear density of yarn might alter the projected fabric qualities, allowing it to fit current fashion market demands, which is the ultimate target of a textile product. The present investigation was designed to evaluate the impact of cotton sheath linear densities of core spun yarn (cotton/spandex) on performance properties like stretchability, tensile and tearing strength, weight, dimensional stability, pilling, and abrasion resistance of denim fabrics. Acquired results revealed that with the upsurge in the linear density of cotton sheath, several properties of the fabric, such as elongation and recovery percentage, tensile and tearing strength in the weft direction were improved because of the utilization of the variable linear density of sheath yarn in the same direction. Width-wise shrinkage and fabric weight were also decreased substantially. It was also found that increasing the sheath count enhances the denim fabric’s overall resistance to pilling.
