Non-woven fabric-based adsorption material with high adsorption capacity and preparation method of non-woven fabric-based adsorption material

The invention discloses a non-woven fabric-based adsorption material with high adsorption capacity, which comprises a base material and an adsorption film layer coated on the surface of the base material, the base material is a non-woven fabric, and the adsorption film layer is a polymeric film layer loaded with an adsorbent or is formed by rapidly forming a film from a high-molecular polymer with adsorption performance. The adsorption film layer provided by the invention adopts a rapid film forming mode, the adsorption film layer penetrates into the non-woven fabric, and fibers on the surface layer of the non-woven fabric are embedded in the adsorption film layer, so that the adsorption material with high specific surface area, high porosity and strong binding force is formed. The product has large adsorption capacity and can be used in the field of dye wastewater treatment. And on the other hand, the method has quite high preparation efficiency, reduces pollution and cost, and is suitable for industrial pro
