Embodiments of the present invention employ the perfluoroalkyl acrylic copolymerisate PD-1, produced by the Clariant Corporation, and certain other similar perfluoroalkyl acrylic copolymerisates, for waterproofing a wide variety of natural and synthetic fabrics and materials. In one embodiment of the present invention, fabrics and materials are passed through a bath of PD-1, or certain other perfluoroalkyl acrylic copolymerisates, and the material or fabric is then cured for a period of time within a range of periods of time specific to the type of material or fabric at a temperature within a range of temperatures specific to the type of material or fabric in order to create a remarkably waterproof, but breathable material or fabric with characteristics and properties identical or similar to those of the untreated fabric. Thus, embodiments of the present invention provide for remarkable degrees of waterproofing of natural and synthetic fabrics, while retaining the breathability characteristics of the natural and synthetic fabrics and materials as well as many other characteristics and properties, including texture, thickness, weight, and other characteristics and properties desirable to users of the materials and fabrics as well as products constructed from the materials and fabrics. |
