Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
The method of making a dual wall fabric comprising the steps of providing a dual-component strand material having components of different free lengths, with the longer component being wound about a shorter core component, integrally weaving the fabric in opposed layers connected and closely spaced by integrally woven dual-component strands, and destructing the core components of shorter free length to release the wound strand components of greater free length to their fully extended lengths, whereby the original spacing between the fabric layers is free to increase.
Claim 2
Independent Claim
86 words
The method of making a dual wall fabric comprising the steps of providing a dual-component strand material having components of different free lengths, with the longer component being wound about a shorter core component, integrally weaving the fabric in opposed layers connected and closely spaced by integrally woven dual-component strands, and destructing the core components of shorter free length to release the wound strand components of greater free length to their fully extended lengths, whereby the original spacing between the fabric layers is free to increase.
Claim 3
Dependent Claim
29 words
The method of claim 1, wherein said destructing is effected by dissolving the core components of shorter free length in a bath of solvent subsequent to weaving the fabric.
Claim 4
Dependent Claim
19 words
The method of claim 1, wherein the weaving step includes weaving the dual-component connecting strand in the filling direction.
Claim 5
Dependent Claim
19 words
The method of claim 1, wherein the weaving step includes weaving the dual-component connecting strand in the warp direction.
Claim 6
Dependent Claim
17 words
The method of claim 2, wherein the solvent is water, including the step of heating the water.
Claim 7
Dependent Claim
44 words
The method of claim 1, wherein said destructing step comprises applying sufficient heat to the core components to render the core components susceptible of fracturing upon expansion of the spacing between the layers, with such heat being insufficient to destruct the wound strand components.
Claim 8
Dependent Claim
50 words
The method of claim 1, wherein said destructing step comprises dissolving the core components by applying a solvent thereto, with the material of the wound strand components having been predetermined to be substantially inert to the solvent, and with the material of the core components being soluble in the solvent.
Claim 9
Dependent Claim
10 words
The method of claim 7, wherein said solvent is water.
Claim 10
Dependent Claim
19 words
The method of claim 1, wherein the destructing operation is effected as part of a continuous fabric making operation.
Claim 11
Dependent Claim
10 words
The fabric made according to the method of claim 1.
Claim 12
Dependent Claim
10 words
The fabric made according to the method of claim 6.
Claim 13
Dependent Claim
10 words
The fabric made according to the method of claim 7.
