ABSTRACT:
A thread is passed through a dyeing apparatus before the thread is supplied to a sewing machine as an upper thread. The dyeing apparatus has a cylinder containing a plurality of coloring members, each coloring member containing a coloring liquid of a different color. The cylinder is rotated by a manually operated dial to select one of the coloring members in accordance with a stitch to be sewn with a sewing machine. A coloring section of the selected coloring member is exposed to the outside of the cylinder for establishing contact between the thread and the coloring section. A heat-set roller is adapted to come into contact with the thread for heat-setting the coloring liquid applied thereto. The contact between the thread and the coloring member and the heat-set roller is actuated in response to operation of the sewing machine.
