SHOE INSOLE USING EXPANDED GRAPHITE SHEET
Document Type and Number:
WIPO Patent Application WO/2018/101555
Kind Code:
A1
Abstract:
A shoe insole of the present invention is characterized in that a heat conductive sheet (20) is inserted between an EVA sponge (10), and a PE fiber and restoration sponge (30), and is adhered, and in that the heat conductive sheet (20) allows a fluorine film (22) to be bonded to both surfaces of an expanded graphite sheet (also called "graphite") (21). The heat conductive sheet (20) allows a seam part (221) to be backstitched to a sewing line (222) along an edge. The seam part (21) is finished in a "right-side-open rectangular" shape, and then, is sewn with a polytetrafluoro ethylene (PTFE) thread in the middle part thereof so as to form the sewing line (222). Another specific example of the heat conductive sheet (20) can be used in the present invention, wherein a carbon fiber sheet (23) is inserted between two sheets of the expanded graphite sheet to which the fluorine film (22) is bonded so as to be produced as a multilayer structure.
