摘要:
Systems and methods for forming an elastic laminate may be disclosed. For example, an elastic material may be extruded onto a first nonwoven web. In the extrusion, the elastic material may be directly applied to the first nonwoven web continuously in a machine direction and discontinuously in a cross direction to form the elastic laminate with one or more elastic strips on the first nonwoven web. The elastic material may also be applied unevenly or non-uniformly in the cross direction strips on the first nonwoven web. A second nonwoven web may be bonded to the first nonwoven web with the one or more elastic strips. The first or second nonwoven may also be pre-activated to further improve stretch and/or softness.
