Abstract :In parallel to the development of new fiber and yarn technologies, different fibers and yarns have been used in denim fabric production and breaking the market dominance of 100% cotton yarn in the denim market. In recent years, the use of elastane fibers for denim fabric production has rapidly increased thanks to their movement comfort. This study examines the strength and elasticity properties of denim fabrics containing core yarns. For this purpose, different weft yarns were used in the production of denim fabrics. While 100% cotton ring yarn was used as warp for all fabrics, cotton ring, cotton OE-rotor, cotton / PBT-elastane dual-core, cotton / elastane core and cotton-PET / elastane core yarns were used as weft. Within the scope of the study, tensile strength, tearing strength and bursting strength tests were carried out on denim fabrics. In addition, denim fabrics contain core spun yarns were tested for elasticity in the weft direction, which is the direction of core yarns used. When the results were examined, it was seen that tensile strength and breaking elongation are higher for the fabrics containing core yarn in general. Fabrics produced with dual-core yarns have the highest tearing strength values. In addition, the bursting strength values of fabrics containing core yarn are higher than fabrics without core yarn. It was seen that the elasticity values of denim fabrics produced using core yarn are generally above 50%. However, the highest growth values were seen in the fabrics with the highest elasticity.
