A composite polyester hot-melt adhesive, a preparation method thereof and a preparation method of an anti-scouring geotextile are provided. The preparation method of the composite polyester hot-melt adhesive includes the following steps: performing an esterification reaction on a dibasic acid and a dihydric alcohol under a protection of nitrogen and an action of a titanium/cobalt composite catalyst, adding a stabilizer for a polycondensation reaction to obtain a polyester hot-melt adhesive, then adding polymethyl methacrylate (PMMA) microspheres for mixing and stirring to obtain the composite polyester hot-melt adhesive. The anti-scouring geotextile is obtained by bonding a polyethylene terephthalate woven fabric with a polypropylene geotextile by the composite polyester hot-melt adhesive. The composite polyester hot-melt adhesive has the advantages of high bonding strength and good anti-impact performance, and the prepared anti-scouring geotextile has the advantages of high anti-scouring strength, good soil conservation performance, strong protection capability and long service life.
