A method of forming a flexible, fluid-permeable coated band comprising: a) mixing together two parts of oleic acid with 100 parts of dioctyl phthalate and then vigorously stirring the resulting mixture with about 80 parts of water contains about 0.25 parts of ammonium hydroxide to form a mild emulsion of oil in water, b) add to the emulsion of operation a) about 100 parts of poly (vinyl chloride) finely subdivided and, by stirring, incorporate it into the emulsion until a homogeneous mixture is obtained, c) spreading the resulting viscous aqueous emulsion over a flexible band to form a liquid layer on it, d) heating the resulting compound at a rate, gradual to a temperature of about 180º C until all the water , the dioctyl phthalate and the polyvinyl chloride have been evaporated and fused, and e) the flexible product comprising a backing made of woven fabric with a c It is a tightly bonded plastic that has a superficial suede appearance and is highly permeable to fluids.
