Further, a cooling air discharge duct 120 is provided at the rear end of the heater 100, and the dyed fabric is completed by cooling the heated fabric to be dyed 10 with the discharged cooling air.

FIG. 2 is a partially cut perspective view showing an embodiment of the heater of the present invention.
In the heater, main frames 131 and 132 are provided so as to be separated from each other in the longitudinal direction, which is the moving direction of the fabric 10 to be dyed, and the main frames are placed below the main frames 131 and 132 at a certain height from the ground. A lower frame 133 is provided for supporting and providing the lower housing 140. Further, an upper frame for providing the upper housing 110 is provided above the main frames 131 and 132. Further, the lower housing 140 and the upper housing 110 are spaced at regular intervals so that the heat dissipated from the far-infrared heater 15 housed inside does not flow out and the apparatus housed inside can be repaired. There are provided doors 134 and 135 which are separated and opened and closed.

  Transfer rollers 11 and 12 driven by motors (not shown) are provided at the front and rear ends of the main frames 131 and 132, respectively, and a transfer belt 13 is provided with the transfer rollers 11 and 12 as support shafts. The dyed fabric 10 is placed on the upper surface of the transfer belt 13 and is transferred by the rotation of the transfer belt 13. Here, the transfer belt 13 is made of a net made of asbestos material. By minimizing the element that hinders the heat transfer of the transfer belt 13 to the fabric to be dyed 10, the upper and lower surfaces of the fabric to be dyed 10 are heated to the same extent by the far infrared rays irradiated to the fabric to be dyed 10. Inside the upper housing 110, a plurality of far-infrared heaters 15 are provided above the upper surface of the transfer belt along the transfer direction so as to heat the fabric to be dyed 10 transferred by the transfer belt 13. It is fixedly installed on an auxiliary frame 136 that is fixed to the frame. A plurality of circulation fans 14 are provided above the far-infrared heater 15, and the circulation fans 14 circulate the air inside the housing 110, and are generated when the fabric 10 is heated by the far-infrared heater 15.

FIG. 3 is a partially cut perspective view showing an example of a far infrared heater used in one embodiment of the present invention.
The far-infrared dissipating ceramic heater rod 152 of the far-infrared heater 15 is formed of a cylinder having a predetermined diameter, and a coil-like heater wire 153 that is an electric heating element is built in the ceramic heater rod 152, and the ceramic A reflector 151 is provided outside the heater bar 152.

Has been.

  Here, if the surface temperature of the ceramic heater rod 152 of the far-infrared heater 15 is 100 ° C. or less, the coloring time is extremely increased. On the other hand, when the surface temperature exceeds 500 ° C., the coloring energy consumption increases rapidly, and the fabric to be dyed may be deformed. Further, if the wavelength of the radiation emitted from the ceramic heater rod 152 is smaller than 5.6 μm, since the far infrared rays have a small transmission power through the fabric to be dyed, only the surface portion of the applied dye is heated. As a result, the coloring effect does not occur, and the phenomenon that the dye dries on the surface of the fabric to be dyed occurs. When radiation of 500 μm or more is emitted, the penetrating power becomes strong and the phenomenon that energy flows out to the outside occurs, so that the dye and the fabric to be dyed are not heated.

  As described above, specific embodiments have been described in the detailed description of the present invention, but it is needless to say that various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention is not limited to the above-described embodiments, but should be determined not only by the claims but also by the equivalents of the claims.

(1) In order to dye on the fabric to be dyed, the coloring process in which the color paste mixed with the dye is applied to the fabric to be dyed and heated with high-temperature and high-pressure steam as before is simply applied to the dye. The energy required for the dyeing can be saved by applying the far-infrared ray to the dyed textile applied to the dyed textile.
(2) Conventionally, the water washing step and the drying step should always be performed after the coloring step, but according to the present invention, since the dyeing process is completed in the coloring step of irradiating far infrared rays, various complicated steps are required. The manufacturing process is simplified.
(3) Conventionally, the contaminated water vapor was discharged in the coloring process and the contaminated waste water was generated in the water washing process, but the discharge source of such waste water and water vapor can be greatly reduced.
