Patent ID: 7309522

Claim:
A fiber produced from a composition comprising 50 to 100 weight % of one or more non-hydrogenated block copolymers, wherein the one or more, non-hydrogenated block copolymers each have at least two blocks produced from vinyl aromatic monomers and at least one block produced from conjugated alkene monomers, wherein the composition has an order/disorder transition (ODT) onset of less than 280° C., and neither the shear modulus, G′, nor loss modulus, G″, monotonically increase with temperature in the range from the ODT, or 150° C. in the absence of an ODT, to 280° C., wherein the fiber is in the form of a conjugate fiber which has a sheath/core or tipped multilobal cross section, wherein the fiber has a diameter less than 400 microns, and wherein the fiber is a conjugate fiber, said conjugate fiber comprising the block copolymer and at least one polyolefin component, wherein said polyolefin component at least partially envelops the block copolymer.
