Abstract (en)
The present invention is intended to provide an organic resin non-crimped staple fiber that has notably few defects and that uniformly disperses in a dispersion medium, and that is preferred for use in wet-laid nonwoven fabrics or resin reinforcement in applications such as in industrial materials and daily commodities. The organic resin non-crimped staple fiber of the present invention has a fineness of 0.0001 to 0.6 decitex, a fiber length of 0.01 to 5.0 millimeters, a moisture content of 10 to 200 weight%, a cut-end coefficient of 1.00 to 1.40, and a coefficient of variation relative to fiber length (CV%) of 0.0 to 15.0%, the cut-end coefficient and the coefficient of variation relative to fiber length being defined as follows: (1) Cut-End Coefficient = b/a, wherein a is the fiber diameter of a single yarn of the non-crimped staple fiber, and b is the maximum diameter at the cut end; (2) Coefficient of Variation Relative to Fiber Length (CV%) = (standard deviation of fiber length)/(mean value of fiber length) x 100 (%), wherein the number of measured single yarns is 50 in (1) and (2). The foregoing object can be achieved with this configuration.
