  • Patent number: 11975296
    Abstract: A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.

  • Patent number: 7820945
    Abstract: Disclosed is a heating fabric comprising a heating fabric element made by weaving woof fibers and warp fibers, a pair of conductive parts being a plain fabric made by a weaving method to extend from one side edge of the heating fabric element, for supplying electric power to the heating fabric element, wherein electrode fibers are woven in rows as warp threads in the conductive parts and a heating fiber is intermittently woven as woof threads at predetermined intervals so as to be conductive with the conductive parts, and wherein the heating fiber is woven in a zigzag pattern on the other side of the plain fabric of the conductive parts, in which one end of the heating fiber is woven into the conductive part, and a portion of the other end of the heating fiber is not woven into the conductive part, thereby forming a jumping portion having a length longer than a width of the conductive part, the jumping portion jumping over the conductive part so as not to be conductive with the conductive part.
