Abstract: Based on the composition and property of T400/polyurethane twin-core yarn, this paper introduces its application in warp elastic denim and weft elastic denim and the related production processes. According to the performance comparison between twin-core yarn denim and conventional stretch denim, the twin-core yarn denim has better elasticity and dimensional stability. Its weft shrinkage rate is under 10% and elastic recovery rate can reach 96%. The wide use of twin-core yarn in denim fabrics makes the fabrics more comfortable and body-fit, which can also meet market demand.
