    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 stretchable laminate is formed by providing a hydroentangled nonwoven fabric exhibiting cross-direction extensibility and recovery, which fabric comprises a nonwoven web of staple length fibers of about 0.8 to 3.0 denier having a basis weight of about 1.0 to 4.0 ounces per square yard. A polymeric binder composition substantially uniformly applied to the nonwoven web imparts desired elasticity to the web, with the fabric exhibiting at least about 50% extensibility in a cross-direction thereof, and at least about 90% recovery in a cross-direction. The nonwoven web may comprise synthetic fibers, natural fibers, and blends thereof, as well as continuous filaments. An elastomeric composition comprising polyurethane or polyvinylchloride is applied to the extensible nonwoven fabric, which forms the stretchable laminate. The laminate provides a highly conformable and aesthetically pleasing leather-like product.
