Problems solved by technology

[0002] Conventional industrial printing and dyeing wastewater is directly discharged, then precipitated, added chemical reagents for precipitation, and then treated in other sedimentation tanks until the treatment is completed, which takes a long time, poor effect and high cost
There are other methods of using filter membranes (PTFE film), most of which use chemical materials, which cannot be degraded naturally or take a long time to degrade, and chemical fibers have problems such as low moisture regain, resulting in poor hydrophilicity and poor adsorption of particulate matter
Moreover, there is no base tissue protection, it is easy to deform, and it is impossible to realize the graded filtration of only large particles, medium particles, and small particles, resulting in low filtration effect

Abstract

The invention discloses a manufacturing method for a printing and dyeing wastewater filter material with good filter effects. The method includes: making a bast fiber yarn into a fabric layer with a space network structure, and conducting low temperature plasma treatment on the fabric layer; making liquid crystal polyarylate fiber into a filter material base layer through acupuncture, spunlace, hot rolling or other non-woven processes, and knitting the fabric layer and the filter material base layer together through a knitting technology; and employing a spinning solution to perform electrostatic spinning through a nanofiber electrostatic spinning device so as to form a nanofiber membrane, which bonds with the upper surface of the filter material base layer automatically due to the high speed impact and the bonding performance of the polymer solution itself so as to form the filter material.
