Abstract (en)
The present invention is directed to a composite elastic yarn, including a core section including an elastic core filament, and a sheath section including staple fibers surrounding the core section, wherein the elastic core filament has a low cohesion property in which the inter-filament cohesion thereof is within the range of 9 to 198 mg when measured according to the ASTM D3822 method, and is also directed to a fabric, and a method for manufacturing a composite elastic yarn. According to the present invention, it is possible to solve a puckering problem occurring on the surface of a denim fabric, thereby improving a touch sensation and the quality of a final product.
