Abstract:
A present invention related to a method for manufacturing a dot bonding shoe insole using an adhesive resin containing hydrophobic nano-silica, including: melting adhesive resin made of any one selected from thermoplastic polyurethane (TPU) or ethylene vinyl acetate (EVA) containing hydrophobic nano-silica in the range of 0.2 to 5 phr and applying to the surface of the transfer roller in which the intaglio dot pattern is formed in a mesh shape in the shape of the shoe insole; removing the adhesive resin applied other area than the intaglio dot pattern of the surface of the transfer roller; transferring the adhesive resin applied to the intaglio dot pattern of the surface of the transfer roller to either one of the foam or the fabric; bonding the foam and the fabric by compressing; and cutting a shoe insole shape in a package in which the foam and the fabric are bonded.
