2106461 9216366 PCTABS00016 A process for producing an elasticized fabric, including forming an array of elastomeric filaments (12) and generally an array of non-elastic filaments (16). The two arrays are combined with one or more layers of simultaneously formed webs of melt blown fibers (32, 44), and optionally prefabricated webs (36, 48). At certain points in the process the web is subjected to tension so as to elongate it and molecularly orient certain elements of the web. The web is then pin-bonded (50) or otherwise adhered together, and then relaxed so as to permit the formation of corrugations, wrinkles or gathers in the melt blown fibrous webs, and kinks, curls and undulations in the non-elastic continuous filaments.
