Abstract
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.
Claims23
A method for forming a laminate with elastic materials extruded thereon, the method comprising:
- receiving a first nonwoven web;
- and
- extruding an elastic material onto the first nonwoven web such that the elastic material is directly applied to the first nonwoven web continuously in a machine direction and discontinuously in a cross direction to form an elastic laminate with one or more elastic strips on the first nonwoven web.
An elastic laminate comprising:
- a first nonwoven web;
- and
- one or more elastic strips of an elastic material extruded directly onto a first surface of the first nonwoven web, wherein the one or more elastic strips extruded directly onto the first surface of the first nonwoven web are continuous in a machine direction and discontinuous in a cross direction.
