ABSTRACT:
A non-woven web is provided that has conformability and drapability approaching that of woven fabrics. The non-woven web comprises a number of substantially parallel continuous filaments that are stabilized by melt blown fibers to create a coherent web. The continuous filaments are molecularly oriented, as by drawing before, during, or after deposition of the melt blown fibers. The melt blown fibers may be deposited on one or both sides of the continuous filaments, and two or more webs may be cross laid and laminated together. In one embodiment, the continuous filaments of a cross laid laminate are not bonded to each other. The continuous filaments are above to slide and slip relative to each other when the laminate is deformed, thereby decreasing stiffness and increasing drapability.
