Abstract
Abstract A method and apparatus for producing a breathable coated fabric is disclosed. The method involves coating a fabric substrate with a resin then opening pores in the resin by directing a flow of air through the fabric substrate and resin coating. The pores provide breathability of the coated fabric and allow for a vapor or moisture transmission rate about ten times that of a resin coated fabric without pores.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
62 words
A process for producing a breathable coated fabric, said process comprised of the steps of: applying a coat of resin to a fabric substrate, forcing a flow of air through said resin coated fabric thereby opening a plurality of pores in said resin coat, processing to a final form said resin coated fabric with a plurality of pores in said resin coat.
Claim 2
Dependent Claim
62 words
A process for producing a breathable coated fabric, said process comprised of the steps of: applying a coat of resin to a fabric substrate, forcing a flow of air through said resin coated fabric thereby opening a plurality of pores in said resin coat, processing to a final form said resin coated fabric with a plurality of pores in said resin coat.
Claim 3
Dependent Claim
25 words
The process of claim 1 wherein said flow of air is hot and sets, at least temporarily, said plurality of pores in said resin coat.
Claim 4
Dependent Claim
16 words
The process of claim 1 wherein said pores in said resin coat are microscopic in size.
Claim 5
Dependent Claim
12 words

Claim 14
Dependent Claim
23 words
The process of claim 1 including the step of adding a gelling or heat sensitive agent to said resin before said applying step.
Claim 15
Dependent Claim
56 words
A breathable coated fabric produced by the steps of: applying a coat of resin to a fabric substrate, forcing a flow of air through said resin coated fabric thereby opening a plurality of pores in said resin coat, processing to a final form said resin coated fabric with a plurality of pores in said resin coat.
Claim 16
Dependent Claim
56 words
A breathable coated fabric produced by the steps of: applying a coat of resin to a fabric substrate, forcing a flow of air through said resin coated fabric thereby opening a plurality of pores in said resin coat, processing to a final form said resin coated fabric with a plurality of pores in said resin coat.
