Description of the Related Art In order to impart water repellency to a fiber cloth, a method in which a fluorine-based water repellent or a silicone water repellent and a cross-linking agent for improving durability are applied and heat treatment is generally performed. ing. According to this method, the bond between the fiber and the water repellent is strong due to the action of the cross-linking agent, but the strong bond and the water repellency often do not match. This is considered to be a phenomenon that occurs because the water-repellent resin film is not sufficiently formed on the surface of the fabric that is in direct contact with water. Therefore, in order to sufficiently form the water-repellent resin film, it is necessary to use more water-repellent resin by that amount, but in this case, it is not a good idea because the cost is increased accordingly.
