The invention discloses a textile used for a swimming suit and a production method thereof. The textile is mainly formed by elastic fiber, and polyester fiber surface of which is provided with anionic groups. The surface of single fiber in the textile is coated with a water-repellent resin film, wherein a fluorine element content of the water-repellent resin film is not less than 0 [mu]g/g and less than 6000 [mu]g/g; a residual amount of ammonium perfluorocaprylate is not more than 0.05 [mu]g/g, and a residual amount of perfluorooctane sulfonate is not more than 0.05 [mu]g/g. The textile is suitable for manufacturing functional swimming suit textile fabrics, and has excellent water repellency functions of low wettability, low water volume and durable rinsibility.
