Water circulation cooling and sweating thermal protection fabric and preparation method thereof

The invention relates to a water circulation cooling and sweating thermal protection fabric and a preparation method thereof. The fabric is composed of fabric layers on the two sides and a middle interlayer. A plurality of flexible porous fiber pipes which are arranged in parallel and are connected into an S shape through U-shaped connecting pipes are arranged in the middle interlayer; and an electromagnetic valve is arranged at the terminal end of the flexible porous fiber pipe. According to the invention, the electromagnetic valve is opened, water circulation cooling realizes fabric cooling, the electromagnetic valve is closed, water flows out from the side wall micropore structure, and clothes thermal protection and cooling effects are realized through water evaporation. The cooling mode is novel, the cooling efficiency is high, the overall structure is not complex, the burden of a wearer can be reduced, and the protection performance is excellent. 本发明涉及一种水循环冷却及发汗热防护织物及其制备方法，所述织物由两侧织物层和中间隔层组成；所述中间隔层内布置有若干平
