Problems solved by technology

[0004] At present, the water-repellent clothing on the market is basically treated with a water-repellent agent containing fluorine, so it must contain PFOA and PFOS substances. Although it can be less than or equal to 0.05μg / g, PFOA and PFOS substances remain It is harmful to the human body
At the same time, there are also some products using non-fluorine water repellent, but the water repellency and other properties cannot reach the performance of fluorine-containing products.

Abstract

The invention discloses a textile subjected to water repellency treatment and a production method thereof. The textile is a woven fabric or a knitted fabric formed from polyester fibers and / or cellulose fibers. Single fiber surfaces of the polyester fibers and / or cellulose fibers are covered with resin films. The resin film at least comprises a non-fluorinated compound containing -CH2- as a main chain with the carbon atom number greater than or equal to 8, and one or more of -Si-H, -NO2, -NO and -COOR (wherein R is shown the description and n is greater than or equal to 3) and a C-H bond as branched chains, or at least comprises a non-fluorinated compound containing a main chain -Si-O- and branched chains of -COOR (wherein R is shown the description and n is greater than or equal to 3) and / or a C-H bond. The textile has excellent washing endurance.

Description

technical field [0001] The invention relates to a water repellent treated textile and a production method thereof. Background technique [0002] Common water-repellent textiles currently on the market are mainly products processed with water-repellent agents containing perfluorooctanoic acid ammonium compound (hereinafter referred to as PFOA) and perfluorooctane sulfonate compound (hereinafter referred to as PFOS). PFOA and PFOS are harmful to the human body when the concentration is higher than a certain level. 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 persistent organic pollutants. Its degra...
