  • Patent number: 9920471
    Abstract: A rain-test resistant, high-vapor-permeable, water-repellent and water-resistant manufacturing process for making such fabrics is provided. It is used in the dyeing and finishing process of fabric in which the fabric is treated with the treatment roller, knife roller, and spray methods. These combined methods can coat water-repellent agent on the fabric and form a very thin film on the fabric. This protective film on the fabric enhances the wash resistance of the fabric while it will not adversely affect the water repellence and water resistance of the fabric. Moreover, this technique of forming a very thin water-repellent film on the fabric rules out the conventional method with which the water-repellent agent dipped within the fabric structure is easily washed out with regular laundry of the fabric due to the lesser amount of the agent being attached onto the fabric.
