Abstract
A laminate comprising a fabric is provided wherein the fabric has comparable strength characteristics to conventional fabrics yet is softer. The fibers of the fabric are a blend of a high crystallinity polypropylene polymer and a random block copolymer of polypropylene and polyethylene. The laminate of this invention may include other spunbond layers, meltblown nonwoven fabrics or films. The laminate of this invention may be used in products such as, for example, garments, personal care products, medical products, protective covers and outdoor fabrics.
