Abstract:
An elastic non-woven laminate fabric, comprising:a) a first and second non-woven fabric web comprised of thermoplastic polymers, said web having a CD elongation of at least 120% and a basis weight of between about 10-100 gm/m2; b) an elastic film comprised of a vinylidene isoprene polymer; said film having a thickness of between about 0.5 to 3.5 mils; said elastic film attached to said first and second non-woven webs with said film and said web in substantially relaxed, un-elongated states; and the elastic non-woven laminate fabric having a CD elongation of at least 120% with an elastic recovery of at least 85% after three cycles of 100% elongation; c) said elastic film being juxtaposed between said first and second nonwoven web in a laminate construction; and d) said laminate construction having a discontinuous bond pattern of no greater than 15% land area.
