Enhancing the Mechanical Properties of Warp-Knitted Elastic Tapes
Abstract
Elastic tape is considered one of the most important clothing accessories because it affects both the functional and aesthetic performance of the apparel. These tapes are manufactured on warp knitting machines with the required width. The problem that many users face; is that the used elastic tapes in garment manufacturing are greatly affected by repeated use due to the stress they are subjected to during use and also during washing. Many factors and different constructions influence the mechanical and aesthetic performance of elastic tapes. In this study, various variables were divided into three groups to determine which would achieve the best conditions for tape production. The samples were tested with selected properties such as width shrinkage after washing, tensile strength and elongation percentage, length shrinkage between both sides after washing the elastic tapes, and tension decay (%, %). The weight and the thickness of the produced elastic tapes were also identified. The results of the mechanical properties were statistically analyzed, indicating that both the tape width and the percentage of rubber threads significantly affect the tested properties. Furthermore, most of the functional properties of elastic tapes improve within a range of 1.5–3.1 cm in width and a rubber thread percentage of 83.1 %. and a rubber thread percentage of 83.1% and which subsequently affects the performance and durability of garments during with repeated use and washing cycles.
