摘要：
A moisture-permeable waterproof coating is formed by coating a fabric with a water-based coating composition containing a film forming polymer and a water-soluble polymer in a proportion of 5 to 70% based on total solids, drying or heating the fabric to form a film thereon; and then treating the resulting film with an aqueous solution of an enzyme which selectively degrades the water-soluble polymer, thereby enzymatically degrading the water-soluble polymer and extracting the degraded water soluble polymer from the film, whereby the film on the fabric is rendered microporous.
