Abstract:
Provided are a C-shaped composite fiber, a C-shaped hollow fiber using the same, a fabric including the C-shaped composite fiber and/or the C-shaped hollow fiber, and a manufacturing method of the C-shaped composite fiber, the C-shaped hollow fiber, and/or the fabric, and more particularly, to a C-shaped composite fiber which has excellent strength and elongation together with improved hollowness, so that there is little deformation of the composite fiber and/or the hollow fiber in the manufacturing process thereof, quality degradation of the hollow fiber is minimized in the elution process thereof, a weight reduction process in a fabric state is not required when manufacturing the fabric, and the manufactured fabric has excellent warmth and lightness, a C-shaped hollow fiber using the same, a fabric including the C-shaped composite fiber and/or the C-shaped hollow fiber, and a manufacturing method of the C-shaped composite fiber, the C-shaped hollow fiber, and/or the fabric.
