Problems solved by technology

The one-step method is to add water-repellent finishing agent and anti-ultraviolet finishing agent to the working solution at the same time, and finish it on the fabric through rolling→baking→baking process. This processing technology is difficult to make the fabric obtain good water-repellent and anti-ultraviolet properties at the same time
In the two-step processing technology, the water-repellent finishing first will reduce the liquid carrying rate during the anti-ultraviolet finishing, and the anti-ultraviolet finishing agent adsorbed on the fabric will be less, making it difficult for the fabric to further obtain better anti-ultraviolet performance, and the subsequent The anti-ultraviolet finishing has a greater impact on the original water-repellent effect; if the anti-ultraviolet finishing is done first and then the water-repellent finishing is done, the anti-ultraviolet effect will be poor

Description

technical field [0001] The invention relates to a water-repellent and anti-ultraviolet finishing agent for textiles and a preparation method thereof, in particular to waterproof and anti-ultraviolet finishing for fabrics such as polyester and nylon. Background technique [0002] At present, multi-functional textiles such as water repellency and UV resistance have been widely used in clothing fabrics (outdoor sports fabrics, sun protection clothing, etc.) and household fabrics (umbrella cloth, tent cloth, etc.). Usually, water-repellent finishing uses 8-carbon fluorine-containing water-repellent finishing agents, which contain harmful substances such as PFOA / PFOS, are not eco-friendly, and have been banned by EU REACH regulations. Most of the anti-ultraviolet finishing uses inorganic salt anti-ultraviolet finishing agents, which are difficult to firmly adsorb on the fabric and are not washable. In the process of processing, water repellency and anti-ultraviolet finishing hav...
