Abstract: Hot-melt adhesive polyester is known as “green adhesive” because of its fast bonding, wide application, relatively non-toxic and less pollution, which is an important direction for the development of adhesives in the world today. The paper introduces the synthesis technology of polyester for hot-melt adhesive, as well as application. The appearance of hot-adhesive polyester products mainly includes particles, rods, powders, fibers and films, which always apply as hot-melt adhesives and low melting point fiber. In these two major application areas, the focus of technology development is to use eco-friendlier, and lower cost modified monomers, as well as direct melt spinning and direct coating to improve product competitiveness and meet different market demands. Through the different formulations of the third and fourth monomers, develop suitable products for different application fields, and expand application markets, including emerging industries like 3D printing, electronics, construction, etc.
