Abstract
A breathable and waterproof composite fabric includes a fabric sheet and a waterproof plastic film. The fabric sheet has a first surface, a second surface and a plurality of micropores extending through the first and second surfaces. The waterproof plastic film is made of a non-porous material and has an outer surface, an inner surface bonded to the first surface, and a plurality of hollow protrusions protruding from the outer surface. Each of the hollow protrusions defines a channel having an inner open end at the inner surface and an outer open end distal from the inner and outer surfaces. A method of making the breathable and waterproof composite fabric is also provided.
Claims9
A breathable and waterproof composite fabric, comprising:
- a fabric sheet having a first surface and a second surface that is opposite to said first surface, and a plurality of micropores extending through said first and second surfaces;
- and
- a first waterproof plastic film made of a nonporous material and having an outer surface, an inner surface that is opposite to said outer surface and that is bonded to said first surface of said fabric sheet, and a plurality of first hollow protrusions protruding from said outer surface in a direction opposite to said fabric sheet, each of said first hollow protrusions defining a first channel that extends through said inner and outer surfaces and that has an inner open end at said inner surface, and an outer open end distal from said inner and outer surfaces, said first channel extending curvedly from said inner open end to said outer open end wherein said inner open end and said outer open end face in different directions that are traverse to each other,
- wherein each of said first hollow protrusions includes an extending tab that extends from said outer open end and that is movable to cover or uncover said outer open end.
