Composite elastic yarn, elastic fabric, and method for manufacturing composite elastic yarn

Disclosed are a composite elastic yarn, a fabric, and a method for manufacturing the composite elastic yarn, the composite elastic yarn comprising a core part consisting of an elastic core yarn and a sheath part consisting of short fibers wrapping the core part, where the elastic core yarn has a low adhesion property in which an adhesion force between filaments is in the range of 9 to 198 mg when measured according to the ASTM D3822 method, and the composite elastic yarn has a low adhesion property in which the adhesion force between filaments is in the range of 9 to 198 mg when measured according to the ASTM D3822 method. According to the present invention, the problem of wrinkling occurring on the surface of the fabric for denim can be solved, thereby improving the tactile sensation and improving the quality of the final product. 本发明揭示一种由复合弹力纱、织物及复合弹力纱的制造方法，该复合弹力纱包括由弹力芯纱构成的芯部与由包裹所述芯部并且以短纤维构成的护层部，在此，弹力芯纱具有依据ASTM D3822方法测量时长丝之间粘合力为9至198mg范围内的低粘合特性，依据本发明，能解决牛仔布用织物表面上发生的起皱(puckering)问题而得以改善触感并提高最终产品的质量。
