Disclosed herein are elastic laminate materials. The elastic laminate materials are laminates of extensible nonwoven fibrous webs and thermoplastic elastic materials. The laminate may be a two-layer composite material having a single nonwoven fibrous web bonded to one side of the thermoplastic elastic material, or it may be a three-layer composite having a nonwoven fibrous web bonded to each side of the thermoplastic elastic material. The extensible nonwoven fibrous webs may be staple fiber webs. The thermoplastic elastic material may be single-layer or multi-layer elastic films, or elastic fibrous layers. Where single- or multi-layer elastic films are used, the films may be breathable films. The elastic material, or some of the staple fibers, or both, may be selected such that the staple fiber webs are thermally compatible with the thermoplastic elastic material to facilitate laminate bonding. Processes for forming the elastic laminate material are also disclosed.
An elastic laminate material comprising a thermoplastic elastic material and a first non-bonded staple fiber web layer, said non-bonded staple fiber web layer bonded to said thermoplastic elastic material, wherein said thermoplastic elastic material comprises elastic polyolefin or a blend of elastic polyolefin and styrenic block copolymer, and further wherein said thermoplastic elastic material comprises a multi-layer film comprising first and external skin layers, each in an amount of from about 3 weight percent to about 20 weight percent of said multi-layer film, said first and second external skin layers comprising a bonding agent, and an interior layer of an elastic polymer in an amount of from about 60 weight percent to about 94 weight percent of the multi-layer film.
