ABSTRACT:
A nonwoven fabric made with multicomponent polymeric strands includes a blend of a polyolefin and elastomeric thermoplastic material in one side or the sheath of the multicomponent polymeric strands. The fabric has improved abrasion resistance and comparable strength and softness properties. The thermoplastic elastomeric copolymer is preferably A-B-A' block copolymer wherein A and A' are each a thermoplastic endblock which includes a styrenic moiety and wherein B is an elastomeric poly(ethylene-butylene) mid block. Composite materials including such multicomponent material bonded to both sides of an inner meltblown layer are also disclosed.
