Abstract
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.
