Abstract
Abstract A three-dimensional knit or woven fabric that is permeable to water vapor but impermeable to liquid water is provided. The fabric includes a first fabric layer, a second fabric layer and a yarn interconnecting the two layers. The two layers and the yarn are preferably made from a synthetic, such as a polyester or nylon. Both the first and second fabric layers have a barrier layer adhered to the outside surfaces thereof which is both impermeable to liquid water and permeable to water vapor. The fabric is imperviously sealed to prevent the infiltration of water.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
90 words
A three-dimensional knit or woven fabric comprising: a first fabric layer having an outer surface, a second fabric layer having an outer surface, and a yarn interconnecting the two layers, wherein the outer surfaces of each of the first and second layers has a barrier layer applied thereto without the addition of an intermediate adhesive that is both impermeable to liquid water and permeable to water vapor, wherein the fabric has edges therealong that are imperviously sealed to promote air entrapment, to prevent infiltration of water and to retain buoyancy.
Claim 2
Dependent Claim
90 words
A three-dimensional knit or woven fabric comprising: a first fabric layer having an outer surface, a second fabric layer having an outer surface, and a yarn interconnecting the two layers, wherein the outer surfaces of each of the first and second layers has a barrier layer applied thereto without the addition of an intermediate adhesive that is both impermeable to liquid water and permeable to water vapor, wherein the fabric has edges therealong that are imperviously sealed to promote air entrapment, to prevent infiltration of water and to retain buoyancy.
