Abstract
This study aims to investigate the effect of employing industrial hemp fibers (Cannabis sativa L.) as an eco-friendly fiber in denim fabric, which is one of the most extensively used fabrics in today’s clothing industry and is popular with all socio-economic groups. In line with this aim, denim fabric samples were developed using conventional and organic cotton ring spun yarns in the warp, and conventional cotton, organic cotton/bamboo/linen, and organic cotton/bamboo/hemp ring, core, and dual-core spun yarns in the weft. The manufactured denim fabric samples’ weight, tensile and tearing strength, stiffness, dimensional change, seam slippage, abrasion, and pilling characteristics were analyzed comparatively using statistical analysis techniques. The findings of the statistical analysis indicated that the core component type was the most significant independent variable for almost all fabric characteristics studied. The usage of linen and hemp fibers in the sheath structure of the weft yarn did not cause nearly any change in fabric weight, abrasion, or seam slippage values, but led to a decrease in mechanical properties. In addition, while they increased fabric stiffness, they had a positive effect on pilling and caused it to decrease.
