Abstract
Abstract A laminate comprising a non-woven or woven fabric backing layer having fibers upstanding therefrom and a film-like facing layer secured to the tips of the upstanding fibers. The facing layer and backing layer are spaced apart from one another and are movable in a plane with respect to each other. The ratio of the unit area of the facing layer to the unit area of the backing layer is greater than that same ratio prior to securement of the layers to one another, producing high and low portions in the facing layer which appear as ripples, puckers or wrinkles. A process for preparing the laminate by first securing the layers to one another and then either shrinking the backing layer or expanding the facing layer.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
A method for producing a leather-like texturized laminate comprising securing a facing layer of a flexible continuous film composed of a material selected from the group consisting of urethanes, vinyl, acrylic, polyamides, polyesters, polyethylene, polypropylene, and silicone, to a backing layer of a textile fabric having upstanding napped or looped fibers secured to one side thereof, the facing layer being secured to the napped or looped fibers of the backing layer such that the backing and facing layers aRe spaced apart from but movable within a plane with respect to each other and then shrinking the backing layer such that the ratio of the unit area of the facing layer to the unit area of the backing layer is greater than the same ratio prior to the securement of the layers te one another and to produce in the surface of the facing layer, high and low portions which appear as ripples, puckers, and wrinkles on the facing layer.
Claim 2
Independent Claim
159 words
A method for producing a leather-like texturized laminate comprising securing a facing layer of a flexible continuous film composed of a material selected from the group consisting of urethanes, vinyl, acrylic, polyamides, polyesters, polyethylene, polypropylene, and silicone, to a backing layer of a textile fabric having upstanding napped or looped fibers secured to one side thereof, the facing layer being secured to the napped or looped fibers of the backing layer such that the backing and facing layers aRe spaced apart from but movable within a plane with respect to each other and then shrinking the backing layer such that the ratio of the unit area of the facing layer to the unit area of the backing layer is greater than the same ratio prior to the securement of the layers te one another and to produce in the surface of the facing layer, high and low portions which appear as ripples, puckers, and wrinkles on the facing layer.
Claim 3
Dependent Claim
21 words
The process of claim 1 wherein localized areas of the backing layer are shrunken, said areas forming a preselected design pattern.
Claim 4
Dependent Claim
20 words
The process of claim 1 wherein the shrinkage is effected by applying a chemical shrinkage agent to the backing layer.
Claim 5
Dependent Claim
24 words
The process of claim 4 wherein the chemical shrinkage agent is applied to localized areas of the backing layer in a preselected design pattern.
Claim 6
Dependent Claim
24 words
The process of claim 1 which further comprises sanding the raised portions of the facing layer to produce a multiplicity of minute perforations therein.
Claim 7
Dependent Claim
21 words
The process of claim 2 wherein the expansion is carried out by applying a chemical expansion agent to the facing layer.
Claim 8
Dependent Claim
21 words
The process of claim 7 wherein the chemical expansion agent is applied to the facing layer in a predetermined design pattern.
Claim 9
Dependent Claim
24 words
The process of claim 2 which further comprises sanding the raised portions of the facing layer to produce a multiplicity of minute perforations therein.
