Abstract (en)
[origin: WO2009078479A1] A conjugate fiber is provided, in which a first component that contains at least 75% by weight of an ethylene-a-olef in copolymer having a melting point of 70 to 1000C and a second component that contains a crystalline polypropylene forma side-by-side cross section, wherein, in a fiber cross section perpendicular to a fiber axis, the first component accounts for 55 to 90% of an outer periphery of the fiber, a borderline between the first component and the second component forms a curve bulging toward the first component, and an area ratio between the first component and the second component (first component/second component) is in a range of 70/30 to 30/70. The conjugate fiber demonstrates low-temperature processability and excellent card passability when processed into a nonwoven fabric, and can produce a bulky nonwoven fabric having excellent uniformity.
