    摘要: Bicomponent fibers having a sheath-core morphology where the sheath is a thermoplastic polymer and the core is an elastomeric compound are made which can be continuously extruded from the melt at high production rates. The elastomeric compound comprises a coupled, selectively hydrogenated block copolymer having high flow. The block copolymer has at least one polystyrene block of molecular weight from 5,000 to 7,000 and at least one polydiene block of molecular weight from 20,000 to 70,000 and having a high vinyl content of 60 mol% or greater. The bicomponent fibers are useful for the manufacture of articlessuch as woven fabrics, spun bond 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 greater than 800 mpm and having a denier from 0.1 to 50 g/9000m.

    摘要: The present invention relates to compositions such as fibers, elastic yarns, wovens, nonwovens, knitted fabrics, fine nets, and articles produced at least in part from a styrenic block copolymer comprising at least two blocks produced from vinyl aromatic monomers and at least one block produced from alkyl-substituted, conjugated alkene monomers, where the block produced from the conjugated alkene may have sufficient substitution so as to prevent or significantly minimize thermal cross-linking of the residual unsaturation in the formed block during fiber formation. Additionally, the composition may be described as processable, without requiring any additives if, for example, the order-disorder-transition (ODT) temperature is less than about 280°C.

    摘要: Splittable multicomponent fibers, to split fibers made from such splittable fibers, to processes for making such splittable and split fibers, and to nonwovens and other substrates made from the split fibers. The splittable multicomponent fibers can comprise one component comprising thermoplastic starch and another component comprising a non-starch thermoplastic polymer. wherein: (i) said second component is capable of being split or removed from said first component to provide at least one split fiber consisting essentially of said first component; and (ii) wherein the split fiber of said first component can have good elongation properties. The splittable multicomponent fibers can also provide split fibers of the thermoplastic starch component. The split fibers corresponding to the thermoplastic polymer component will have a greater elongation than directly spun thermoplastic fibers which have an equivalent mass through put as the thermoplastic polymer component of the multicomponent fiber and which have the same diameter as the split fiber.
