Abstract
An extendable laminate having cross-directional extendability includes a film layer laminated to at least one neckable facing layer. The laminate can be made by attaching the film layer to the neckable facing layer to form the laminate, longitudinally slitting the laminate into a plurality of laminate strips, and necking the plurality of laminate strips. The laminate may be incorporated into an absorbent garment as an outer cover material, for example.
Claims28
An extendable laminate comprising:
- a plurality of laminate strips, each laminate strip including a film layer laminated to at least one neckable facing layer, wherein the facing layer of each laminate strip is necked, and each laminate strip possesses cross-directional extendability.
A method of making a laminate having cross-directional extendibility, comprising:
- laminating a film layer to a neckable nonwoven web to form a laminate;
- longitudinally slitting the laminate into a plurality of laminate strips;
- and
- longitudinally stretching the plurality of laminate strips to cause necking of the laminate strips.
A method of making an absorbent garment, comprising:
- laminating a film layer to a neckable nonwoven web to form an outer cover laminate;
- longitudinally slitting the laminate into a plurality of laminate strips;
- longitudinally stretching the plurality of laminate strips to cause necking of the laminate strips;
- and
- applying at least one of the plurality of laminate strips to a garment assembly to form the absorbent garment.
A wound roll of multiple strips of a slit necked extendable laminate, each of the strips having substantially identical cross-directional properties.
