Abstract
An elastic laminate is provided including outer facing layers of a fabric and, located between the outer facing layers, a series of individual, spaced apart strips of elastic film extending continuously along the direction of elasticity. The film strips are formed by a controlled tearing of a continuous film while the film is biaxially stretched and bonded to the fabric facings. The fabric facings have gathers formed therein that allow the elastic laminate to stretch at least to the extent that the gathers can be pulled flat.
Claims24
An elastic article comprising:
- a multi-layer laminate extending in a first direction and a second direction perpendicular to the first direction and wherein said laminate is elastic in said first direction;
- said laminate having a first fabric layer and wherein said first fabric is extensible in the first direction;
- said laminate having an elastic layer adjacent said first fabric layer and wherein the elastic layer includes a series of spaced apart, elastic film strips extending continuously in the first direction, wherein the elastic film strips are formed by tearing a continuous elastic film of the elastic layer, adjacent said first fabric, into the elastic film strips during lamination of the elastic article, said elastic film strips having jagged and irregular side edges that extend along said first direction;
- and
- wherein the laminate has an air permeability of between about 150-1000 CFM.
