Patent ID: 7794819

Claim:
An elastic composite comprising: a first nonwoven, said first nonwoven being extensible, but inelastic, said first nonwoven having a CD extension at peak load of at least 200%, said first nonwoven being further characterized by a CD/MD elongation ratio of at least 3:1, said first nonwoven being a point-bonded carded nonwoven made of staple fibers or a spunlaced nonwoven, said first nonwoven having a basis weight in the range of 10-40 g/m 2 , a second nonwoven, said second nonwoven being extensible, but inelastic, said second nonwoven having a CD extension at peak load of at least 200%, said second nonwoven being further characterized by a CD/MD elongation ratio of at least 3:1, said second nonwoven being a point-bonded carded nonwoven made of staple fibers or a spunlaced nonwoven, said second nonwoven having a basis weight in the range of 10-40 g/m 2 , a first elastic film and a second elastic film, said first elastic film and said second elastic film being laterally spaced apart from one another and sandwiched between said first nonwoven and said second nonwoven, said first elastic film and said second elastic film being bonded to said first nonwoven and said second nonwoven, respectively, by a plurality of continuous lines of a hot melt adhesive extending in the MD direction when said first elastic film and said second elastic film being non-tensioned, a non-extensible material between said first elastic film and said second elastic film and being sandwiched between and bonded to said first nonwoven and said second nonwoven, whereby when the elastic composite is stretched in the CD direction, said nonwovens extend with said elastic films and when the elastic composite is relaxed, said nonwovens bulk.
