Patent ID: 8388594

Claim:
A stretchable laminate comprising: a. a first nonwoven web, said first nonwoven web comprising: i. a first layer of fibers comprising spunbond fibers, said first layer having a top and an bottom surface, said fibers of said first layer forming a plurality of interstices; ii. a second layer of fibers comprising meltblown fibers, said second layer having a top and an bottom surface wherein the top surface of second layer of meltblown fibers faces the bottom surface of said first layer of spunbond fibers, wherein said second layer of meltblown fibers has a basis weight of between 025 and 5 g/m 2 , wherein at least some of said meltblown fibers are located inside some of the interstices of said first layer; iii. at least a third layer of fibers comprising meltblown fibers, said third layer having a top and a bottom surface wherein the top surface of said third layer of meltblown fibers faces the bottom surface of said second layer of meltblown fibers, wherein said third layer of meltblown fibers has a basis weight of between 0.25 g/m 2 and 5 g/m 2 ; iv a fourth layer of fibers comprising spunbond fibers, wherein said spunbond fibers are multi-component fibers having a core comprising a first polymer having a first melt temperature and a sheath comprising a second polymer having a second melt temperature wherein said second melt temperature is lower than said first melt temperature, said fourth layer having a top and a bottom surface, wherein the top surface of said fourth layer of spunbond fibers faces the bottom surface of said third layer of meltblown fibers wherein said fourth layer has a basis weight of between 1 g/m 2 and 25 g/m 2 ; v. at least a fifth layer of fibers comprising spunbond fibers wherein said spunbond fibers are multi-component fibers having a core comprising a first polymer having a first melt temperature and a sheath comprising a second polymer having a second melt temperature wherein said second melt temperature is lower than said first melt temperature, said fifth layer having a top and a bottom surface, wherein the top surface of said fifth layer of spunbond fibers faces the bottom surface of said fourth layer of spunbond fibers such that said second, third and fourth layers are positioned between said first and fifth layers and wherein said fifth layer has a basis weight of between 1 g/m 2 and 25 g/m 2 ; and b. a web of an elastomeric material having top and bottom surfaces, wherein the bottom surface of said fifth layer comprising spunbond fibers of said first nonwoven web is bonded to said top surface of said elastomeric web to form a laminate.
