Embodiment 1
[0017] A method for manufacturing a printing and dyeing wastewater filter material, comprising: using bast fiber yarn to make a fabric layer 1 with a spatial network structure, and performing low-temperature plasma treatment on it; Polyarylate fibers are used to make the filter material base layer 2, and the filter material base layer 2 is treated with low-temperature plasma, and the fabric layer 1 and the filter material base layer 2 are knitted together by a knitting process; the spinning solution is used for electrostatic spinning with a nanofiber electrospinning device. Spinning, so that the polymer solution forms a charged jet stream, and the charged polymer solution jet stream is stretched, thinned, bent, and split to be arranged on the surface of the filter material base layer 2 in a disordered manner to form a nanofiber membrane 3. Due to the high-speed impact of the polymer solution and its own adhesive properties, the nanofiber membrane 3 is bonded to the upper surfac...
