ELASTOMERIC FIBERS COMPRISING CONTROLLED DISTRIBUTION BLOCK COPOLYMERS |
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/9000m. |
