Problems solved by technology

[0004] At present, water-repellent clothing with PFOA and PFOS content less than 0.05 μg / g is basically treated with fluorine-based water-repellent agent or non-fluorine-based water-repellent agent alone, although these two methods have a good water-repellent effect , but it still cannot meet some garments with high requirements for water release performance

Abstract

The invention discloses a textile subjected to water repellency treatment and a production method for the textile. The textile mainly comprises cationic dye-dyeable modified polyester fibers and / or nylon fibers; the single fiber surface of the textile is at least covered with a resin film formed by water-repellent C6 fluororesin and water-repellent non-fluororesin; the surfaces of the cationic dye-dyeable modified polyester fibers and / or nylon fibers have anionic groups. The textile has durable washability and high water repellency.

Description

technical field [0001] The invention relates to a water repellent treated textile 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 251mg / kg. PFOA is also difficult to degrade in the environment and has the characteristics of persiste...
