    摘要： Bicomponent fibers comprising a thermoplastic polymer and an elastomeric compound are made which can be continuously extruded from the melt at high production rates. The elastomeric compound comprises a selectively hydrogenated block copolymer having a controlled distribution elastomeric block which has a mono alkenyl arene blockiness index of less than 40 mol % and high flow. Elastomeric fibers are also provided which comprise a controlled distribution block copolymer and a slip agent. The fibers are useful for the manufacture of articles such as woven fabrics, spunbond non-woven fabrics or filters, staple fibers, yarns and bonded, carded webs. The bicomponent fibers can be made using a process comprising coextrusion of the thermoplastic polymer and elastomeric compound to produce fibers at spinning speeds of at least 1000 mpm and having a denier from 0.1 to 50 g/9000 m.

    摘要： A latently crimpable conjugate fiber is constructed using a first component containing an ethylene-α-olefin copolymer polymerized with a metallocene catalyst and a second component formed from a thermal plastic polymer having a melting point T2 higher than a melting point T1 of the first component, such that the first component is exposed with an exposed length of at least 20% relative to a peripheral length of the fiber, and which fiber has a single fiber dry heat shrinkage percentage of at least 50%, which is determined according to JIS-L-1015 (dry heat shrinkage percentage) at 100° C. under an initial tension of 0.018 mN/dtex (2 mg/d) for 15 minutes and a single fiber dry heat shrinkage percentage of at least 15%, which is determined under the same condition under an initial tension of 0.450 mN/dtex (50 mg/dtex) for 15 minutes. The latently crimpable conjugate fiber develops crimps and has thermal adhesiveness at a low temperature.
