PROBLEM TO BE SOLVED: To provide a moisture-permeable waterproof fabric having excellent flexure resistance and wear resistance.SOLUTION: There is provided a moisture-permeable waterproof fabric having a polyurethane resin layer containing 5 to 50 mass% of polytetrafluoroethylene fine particles on at least one surface of a fiber cloth. The resin layer is preferably obtained by laminating a perforated layer, an unperforated layer or a perforated layer and an unperforated layer in this order. The use of a predetermined amount of polytetrafluoroethylene fine particles can impart flexure resistance and wear resistance to a fabric and in addition to this, the whole resin layer has high hydrophobicity because polytetrafluoroethylene fine particles are hydrophobic, and thus, an effect of imparting washing durability to waterproof performance (waterproof performance) can be obtained. |
