The present inventors conducted intensive studies for solving the problems. As a result, they found a heat-sealable polyester resin which can be used for food application and which exhibits excellent adhesiveness to various containers made of polystylene, polyvinyl chloride, A-PET (amorphous polyethylene terephthalate) , or polypropylene, each having different property.

The aim of the present invention is to provide a polyester resin which exhibits excellent adhesiveness to various substrates such as polystylene, polyvinyl chloride, or A-PET.

According to the present invention, there is provided a polyester resin containing a polycarboxylic acid component and a polyhydric alcohol component as constitution units, wherein, when the total amount of the polyhydric alcohol component is taken as 100 mol%, the content of diethylene glycol component is 60 mol% or more, and wherein the glass transition temperature of the polyester resin is 20° C. or lower.

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.
