Modified polyester resin and hot-melt-adhesive conjugate fibers using the same
 Hot-melt-adhesive conjugate fibers consisting of a fiber-forming component and an adhesive component are provided, with at least one of the fiber-forming component and the adhesive component being a low-melting, modified polyester resin obtained by subjecting to polycondensation, a diol component consisting of 3 to 40 molar % of a 2,2-dialkyl-substituted-1,3-propanediol and 60 to 97 molar % of ethylene glycol and/or 1,4-butanediol, and an aromatic dicarboxylic acid, said low-melting, modified polyester resin having a melting point range between the melting point of polyethylene and a temperature at least 20.degree. C. lower than the melting point of highly crystalline polyethylene terephthalate.
