ABSTRACT:
A process for preparing an insulation wire wherein the wire is dipped into a water dispersion synthetic resin and a resin layer is formed thereon by electrodeposition, and then the wire is immediately treated in a hot water or steam bath to co-melt colloidal particles of the resin in the resin layer, whereby the water in this resin layer is forced to move to the surface so that the water content may be kept at a minimum. The water on the resin layer is removed by blowing air thereacross and a vapor of a film-forming agent is then applied to the wire at high wire running speeds before the resin layer is cured in a heating furnace.
