Abstract
The present invention relates generally to nonwoven materials, and specifically, to a nonwoven fabric comprised of at least three continuous filament precursor webs, each precursor web being of a thermoplastic polymer dissimilar from the other precursor webs, wherein the resulting durable nonwoven laminate fabric exhibits improved tactile and ductile qualities, as well as improved tensile strength, the nonwoven fabric being eminently suitable for application in improving the comfort and use of hygiene, medical and industrial products.
