(57) [Summary] [Purpose] To provide a water-repellent belt having high strength, high toughness, antifouling property and water absorption preventing property, hard to be wetted by water, excellent in workability, and durable. [Structure] Strength of 8.0 g / denier or more, elongation at break 1 It is woven and heat-treated by using a raw yarn having a content of 5% or more and a perfluoroalkyl group-containing compound added in an amount of 0.1 to 3.0% by weight together with a spinning oil agent in the raw yarn manufacturing stage. [Effect] The monofilament constituting the belt can be uniformly subjected to water repellent treatment, and can exhibit water repellent performance after weaving and dyeing. Dust-free belt with no adhesion or mold, no penetration of water into the belt due to capillary action, less workability due to weight increase, and less deterioration due to freezing or hydrolysis due to inclusion of water.
