[0002] At present, the development ideas of imitation cotton mainly focus on three aspects: 1. Elastic imitation cotton-visual: Through the compounding of LTY and matte, matte high elastic imitation cotton composite fiber is obtained. Product features, visual and hand feel close to natural cotton, in addition to elasticity, anti-aging and other characteristics. Let consumers touch and see. It is an excellent and intuitive imitation cotton product. 2. Elastic imitation cotton-feel: Through the compounding of LTY and semi-gloss, semi-gloss high elastic imitation cotton composite fiber is obtained. Product features, visually similar to imitation cotton, hand feel close to natural cotton, and elasticity. 3. Elastic imitation cotton-functionality: Through the color absorption difference characteristics of LTY interwoven elastic yarn and polyester, the positive washing effect is achieved by adjusting the temperature in the dyeing and finishing process. It can also be made into a single color by adjusting the temperature. In this way, the functions of elasticity, different colors, absorption and discharge can be integrated. In summary, the above three development directions, MTY cotton elastic yarn is widely used in knitting and woven sports and leisure fabrics.
