Strength of cotton dual-core elastane yarn splice

Cotton/elastane yarns are composite yarns composed of a blend of elastane core covered with cotton fibres. An increase in the demand for sports and leisure garments with high comfort and elasticity has led to more significant usage of elastane filaments. New yarn using two elastane filaments with a high ratio of elastane are introduced. An experimental study was established to define the most appropriate parameters for spliced cotton dual-core elastane yarn strength. The splice strength was enhanced when binding air pressure, joining air duration, and preparation duration were raised. Increased preparation air pressure does not affect the strength of the splice.
