Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A C-shaped hollow fiber consists of one C-shaped cross section comprising a sheath part and one hollow part, and the sheath part including an open slit, wherein the C-shaped hollow fiber satisfies all of the conditions (1) to (4) below. 30 ≤ hollowness ( % ) ≤ 65 ( 1 ) 20 ° ≤ slit angle ( θ ) ≤ 30 ° ( 2 ) 0.13 < hollowness ( % ) 100 × slit spacing ( d ) < 0.33 ( 3 ) 1 ≤ Eccentric distance ( s ) × R 2 R 1 < 2.4 ( 4 ) where, the slit angle (θ) is an angle between two straight lines each connecting a center of a cross section of the hollow part and two discontinuous points of a sheath part, the slit spacing (d) is a distance (μm) between two discontinuous points of the sheath part, the eccentric distance (s) is a distance (μm) between a center of an entire cross section of the C-shaped hollow fiber including the hollow part and the center of the cross section of the hollow part, R 1 is a diameter (μm) of the entire cross section of the C-shaped hollow fiber including the hollow part, and R 2 is a diameter (μm) of the cross section of the hollow part of the C-shaped hollow fiber. 2. The C-shaped hollow fiber of claim 1 , comprising at least any one component of polyester or polyamide. 3. The C-shaped hollow fiber of claim 1 , further satisfying the condition (5) below. 2.5 < EXP ( eccentric distance ( s ) × slit spacing ( d ) ) 4 cos ( slit angle ( θ
