PURPOSE: A silicon liquid cartridge for sewing is provided to prevent the down of duck filled in a down jumper from escaping by applying silicon liquid to the surface of an upper thread. CONSTITUTION: A sewing machine sews outshell(11) and lining(12) using an upper thread(1) and a lower thread. A silicon liquid cartridge is mounted to the main body of the sewing machine. The silicon liquid cartridge includes an injection hole(21), inlet/outlet holes(22, 23), and guide rollers(24, 25). The injection hole supplies a silicon liquid from the outside through a supplying hose(h). The upper thread is passed through the inlet/outlet holes. The guide rollers are pivotally installed in the cartridge and guide the upper thread.
