Abstract:
1. A process for forming a multilayer construction comprising: (a) forming a first spunbond layer; (b) meltblowing to form at least one elastic meltblown layer comprising wherein the propylene-α-olefin copolymer is meltblown at a melt pressure of from about 750 psi to about 2000 psi to form the elastic meltblown layer; (c) forming a second spunbond layer; and (d) adhering the elastic meltblown layer to the first and second spunbond layers, wherein the elastic meltblown layer is between the first and second spunbond layers; wherein the elastic meltblown layer is formed by meltblowing the one or more polyolefin polymer(s) directly upon at least one of the first or second spunbond layers; and wherein at least one of the first or second spunbond layers comprises spunlace.
