Abstract

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.

Description

technical field [0001] The invention relates to a textile for swimwear and a production method thereof. Background technique [0002] The common textiles with water-repellent function on the market are mainly products processed by water-repellent agents containing perfluorooctanoic acid ammonium compound (hereinafter referred to as PFOA) and perfluorooctane sulfonate compound (hereinafter referred to as PFOS). However, if the residual PFOA and PFOS in the body are higher than a certain concentration, it is harmful to the human body. PFOS is one of the most difficult to degrade organic pollutants found in the world, with high bioaccumulation and multiple toxicity. Among them, many kinds of toxicity are liver toxicity, male reproductive toxicity, variable genotoxicity, nerve damage toxicity, developmental delay toxicity and endocrine interference toxicity. It is 251 mg / kg. PFOA is also difficult to degrade in the environment and has the characteristics of persistent organic...
