Preparation method of novel geotechnical cloth based on recycling of waste masks

The invention discloses a preparation method of novel geotechnical cloth based on recycling of waste masks, and relates to the technical field of geosynthetic materials. Comprising the following steps: mixing polypropylene, tetramethyl divinyl disiloxane and potassium persulfate, and performing melt extrusion to obtain organic silicon modified polypropylene; the organic silicon modified polypropylene, polyethylene glycol terephthalate fiber monofilaments, waste masks and triallyl isocyanurate are subjected to a mixed reaction and then filtered to obtain filter residues, the filter residues are subjected to freeze drying treatment, and modified polyethylene glycol terephthalate fibers are obtained; and uniformly mixing the modified polyethylene glycol terephthalate fiber, polyvinyl alcohol, an antioxidant and water, filtering to obtain a filter cake, drying the filter cake to obtain a dried substance, and needling and solidifying the dried substance to obtain the geotextile. According to the method, the perfor
