Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
125 words
A method for producing a fabric item comprising the steps of: producing a perforated stretchable substrate in the shape of the desired fabric item and having a multiplicity of perforations extending therethrough; providing a pressurized flow of a liquid to said substrate producing a pressure gradient for inflating said substrate, thereby stretching it and expending the perforations thereof thereby to facilitate the entry of fibers thereinto; supplying fibers to said pressurized flow of said liquid thereby causing said fibers to engage the perforations in said substrate by driving said fibers itno said enlarged perforations through means of said pressurized liquid in which said fibers are suspended; terminating said pressurized flow of said liquid; and retaining said fibers in the perforations to define said fabric item.
Claim 2

Claim 3
Dependent Claim
17 words
A method according to claim 1 and wherein said fabric item comprises a shaped three dimensional garment.
Claim 4
Dependent Claim
30 words
A method for producing a fabric item according to claim 1 and wherein said producing step comprises the step of inserting a mold into a bath of fluidized plastic material.
Claim 5
Dependent Claim
19 words
A method according to claim 1 and wherein said producing step comprises the steps of producing a multilayered substrate.
Claim 6
Dependent Claim
17 words
A method according to claim 1 and wherein said producing step comprises extrusion of a web sleeve.
Claim 7
Dependent Claim
18 words
A method according to claim 1 and wherein said producing step comprises the step of perforating said substrate.
Claim 8
Dependent Claim
32 words
A method according to claim 1 or claim 3 and wherein said producing step comprises applying a substrate material to a mold having a plurality of protrusions defining perforations in said substrate.
Claim 9
Dependent Claim
19 words
A method according to claim 1 and wherein said producing step comprises applying a perforating roller over said substrate.
Claim 10
Dependent Claim
38 words
A method according to claim 1 and wherein said producing step comprises the steps of forming said substrate from a material including portions of a soluble substance interspersed therein and dissolving said soluble substance to define said perforations.
Claim 11
Dependent Claim
49 words
A method according to claim 1 and wherein said causing step comprises the step of producing a pressure gradient in the vicinity of said perforated substrate and providing individual fibers at the higher side of said pressure gradient such that the individual fibers engage the perforations in said substrate.
Claim 12
Dependent Claim
32 words
A method according to claim 1 and wherein said retaining step comprises the step of applying a binding agent to a surface of said substrate for binding said fibers in said substrate.
