Abstract

Abstract A waterproof insert for lining the interior of contoured articles of clothing is described, which comprises two superimposed layers, each of which is a laminate composed of a sheet of porous polymeric membrane (1, 1') and a sheet of textile material (3, 3'), the said sheet of polymeric membrane being breathable but waterproof and coated with a breathable, hydrophilic polymer. The sheets are laminated by means of a discontinuous adhesive (2, 2') and the layers are joined to form a uniformly welded seam. The inserts slide easily over the inner protective lining of the article of clothing.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 149 words
A waterproof insert for lining the interior of contoured articles of clothing, which comprises: two superimposed layers, each of which is a laminate composed of a a) a sheet of porous polymeric membrane and, b) a sheet of a textile material, said porous polymeric membrane being breathable but waterproof and being coated with a breathable hydrophilic polymer, said sheets being laminated by a discontinuous adhesive of thermoplastic polymer, said laminates being superimposed so that the sheets of textile material are in adjacent, abutting relationship, said laminates being joined along that portion of the laminates that lie in a path that follows the contour of the article of clothing, said joining being achieved by the presence of said adhesive throughout the area of the textile materials of each laminate adjacent the contour path and by interconnection of the adhesive from each laminate at the abutting surface of the textile material.
Claim 2
Dependent Claim 149 words
A waterproof insert for lining the interior of contoured articles of clothing, which comprises: two superimposed layers, each of which is a laminate composed of a a) a sheet of porous polymeric membrane and, b) a sheet of a textile material, said porous polymeric membrane being breathable but waterproof and being coated with a breathable hydrophilic polymer, said sheets being laminated by a discontinuous adhesive of thermoplastic polymer, said laminates being superimposed so that the sheets of textile material are in adjacent, abutting relationship, said laminates being joined along that portion of the laminates that lie in a path that follows the contour of the article of clothing, said joining being achieved by the presence of said adhesive throughout the area of the textile materials of each laminate adjacent the contour path and by interconnection of the adhesive from each laminate at the abutting surface of the textile material.
Claim 3
Dependent Claim 12 words
The insert of Claim 1 wherein the porous membrane is expanded polytetrafluoroethylene.
Claim 4
Dependent Claim 14 words
The insert of claim 1 or 2 wherein the textile ma­terial is a non-woven.
Claim 5
Dependent Claim 14 words
The insert of claim 1, 2 or 3 wherein the adhesive is a polyurethane.
Claim 6
Dependent Claim 101 words
Process for manufacturing a waterproof insert according to claim 1 comprising the following steps: 1) laminating a sheet of porous polymeric membrane that is breathable but waterproof and is coated with a breathable hydrophilic polymer to a sheet of textile material by using a discontlnuous adhesive of a thermoplastic polymer, 2) placing two of said laminates together to form a layered structure with the sheets of textile material adjacent one another in abutting relationship, 3) bonding said laminates together along a contour path by causing the breathable thermoplastic adhesive polymer to flow together through the textile material layers of each laminate.
Claim 7
Dependent Claim 11 words
Process of Claim 5 wherein the porous membrane is expanded polytetrafluoroethylene.
Claim 8
Dependent Claim 13 words
Process of claim 5 or 6 wherein the textile ma­terial is a non-woven.
Claim 9
Dependent Claim 13 words
Process of claim 5, 6 or 7 wherein the adhesive is a polyurethane.
Claim 10
Dependent Claim 18 words
Process of claim 8 wherein the adhesive is caused to flow by applying heat to the layered laminates.
