PRODUCTION OF MOISTURE-PERMEABLE AND WATERPROOF CLOTH

摘要

PURPOSE:To provide a process for producing a moisture-permeable and waterproof cloth having an excellent combination of moisture permeation and waterproofness as well as soft fabric hand through the coating operations. CONSTITUTION:A cloth is coated with water-soluble substances which remaining very fine uncoated spots uniformly distributed over the cloth surface so that the coated area reaches 10 to 70% of the whole area. Then, a synthetic polymer solution mainly containing a polyurethane resin including inorganic fine powder particles is applied to the coated surface of the cloth, then the cloth is dipped in water to effect wet coagulation of the resin layer and leach out the water-soluble substance.
