Abstract

The present invention relates to a method for manufacturing a conductive fabric sheet comprising a hot-melt layer, in which the conductive fabric sheet is used in a gasket for shielding electromagnetic waves. The present invention provides a method for manufacturing an electromagnetic wave-shielding conductive fabric sheet comprising a hot-melt layer formed on a conductive fabric member, the method comprising the steps of : (a) applying liquid hot-melt resin on a release liner and drying the applied hot-melt resin to prepare a thin, flat hot-melt film; and (b) laminating and bonding the hot-melt film, prepared in step (a), onto a conductive fabric member. The manufacturing method of the present invention can significantly reduce the consumption of hot-melt resin compared to the prior process, can prevent the conductivity and flexibility of the fabric member from being reduced due to the infiltration of hot-melt resin between the textures of the conductive fabric member, can increase the bonding strength between the hot-melt layer and the conductive fabric member, and can reduce the occurrence of burrs when the fabric sheet is cut.
