This raincoat has been made from a plain weave cotton fabric that has been blended with rubber to make it waterproof.
In 1823, Macintosh patented his process for making waterproof fabric. This process involved sandwiching a layer of molded rubber between two layers of fabric treated with the rubber-naphtha liquid. It took some time to develop the industrial process for spreading the rubber-naphtha mixture on the cloth. The patented waterproof fabric was produced in factories beginning in 1824. The first customer was the British military.
