    摘要： The present invention relates generally to nonwoven materials, and specifically, to a nonwoven fabric comprised of at least two continuous filament precursor webs, each precursor web being of a polyolefin polymer dissimilar from that of the other precursor web, wherein the resulting lightweight nonwoven laminate fabric exhibits improved tactile and ductile qualities, the nonwoven fabric being imminently suitable for application in improving the comfort and use of hygiene, medical and industrial products. The lightweight nonwoven fabric is manufactured with a minimum level of processes complexity, and can be either used as a replacement for an existing facing layer, such as a topsheet of a hygiene product, or used in conjunction with an existing construct so as to improve long-term comfort.

    摘要： A thermoplastic film, and the articles thereof, consisting essentially of vinyl copolymer which exhibits sufficient structural durability and enhanced drapeability suitable for application as a breathable barrier layer in disposable end-use articles such as disposable hygiene and protective medical/industrial products. A preferred form of the vinyl copolymer are those selected from the ethylenic acrylates, with ethylene methyl acrylate being most preferred. Melt additives can be compounded with the ethylene methyl acrylate prior to extrusion include colorants, softening agents, UV stabilizers, and surface energy modifiers such as anti-static, hydrophobic and hydrophilic compounds.
