Single and multicomponent polymeric strands including a blend of a melt-extrudable polyolefin and a heterophasic polypropylene composition. The heterophasic polypropylene composition includes three polymers and is normally not melt-spinable into strands by itself. In the multicomponent strands, the blend is in one side or the sheath. Fabric made with such strands is also disclosed and has improved combinations of strength, abrasion resistance, and softness properties. Composite materials including the foregoing fabric bonded to both sides of an inner meltblown layer are also disclosed. In addition, garments made with the fabric are disclosed.
