PROBLEM TO BE SOLVED: To provide an elastic coated fabric having excellent moisture-permeable waterproof properties and windproof properties without giving any influence on the environment, and a manufacturing method thereof.SOLUTION: Water-repellent finishing is applied to an elastic coated fabric, by using a fluorine-based water repellent (C6 fluorine-based water repellent) consisting of a copolymer containing a perfluoroalkyl group with a carbon number of 6 or less. This has no influence on the environment because any C8 fluorine-based water repellent comprising a perfluorooctanoic acid, a perfluorooctane sulfonic acid or the like is not used. In addition, the toluene volatility of the fluorine-based water repellent is 100 seconds or more, the thixotropy index of a synthetic resin solution coated on at least single-side of the elastic fiber fabric is in the range of 1.4 to 2.0 at 23°C, and the 100% modulus of the synthetic resin is 5 kgf/cmor more. Therefore, a coating resin film excellent in film forming properties without any back leakage of the synthetic resin is formed. |
