In other words, the transparent plate 155 prevents the energy of the lamp 153 from being blocked by the chemical liquid 11 adhering to the lamp 153 or the lamp electrode 153a, thereby preventing energy loss, or adhering to the electrode 153a and causing electric leakage. To prevent that.
- a black light was used for the lamp 153 of the light source unit 15.
- a black light is a lamp in which a phosphor that emits long-wavelength ultraviolet light is applied to the inner wall of a glass tube. It emits long-wavelength ultraviolet light (300 to 450 nm) with a peak wavelength in the vicinity of 353 to 370 nm. It can be used effectively.

- the frame 150 may be configured as one space without using the hollow duct 151. Even in this case, temperature adjusting air is introduced from one side of the frame 150 and exhausted from the other side. However, by using the hollow duct 151, the flow of the cooling air can be made uniform in the frame 150.

- the yarn and fabric 10 are repeatedly irradiated with ultraviolet light by the plurality of light source units 15 on both the front and back sides to bleach and modify. It is done.
- the temperature of the light source unit 15 rises.
- the increase in temperature raises the temperature of the entire fiber and fiber structure bleaching / modifying device, promotes the evaporation of the chemical solution 11 impregnated in the yarn, fabric, etc.10, and the yarn, fabric, etc.10 easily dries.
- the temperature adjusting fan is rotated, and the temperature adjusting air is sent from the air blowing port 156 to the lower hollow duct 151.
- the air sent into the hollow duct 151 enters the lamp housing space 154 through the vent hole 151 a and is warmed by the lamp 153.
- the warmed air rises along the lamp 153, enters the upper hollow duct 151 from the vent 151a, and enters the exhaust 157 Power is discharged to the outside.
- the lamp 153 is protected by the frame 150 and the transparent plate 155. Therefore, since the lamp 153 is not soiled, the force that does not need to be cleaned is deposited on the transparent plate 155 of the light source unit 15, and the droplet of the chemical solution 11 adheres, and the light transmittance decreases with time. In such a case, the transmittance can be restored by removing the light source unit 15 from the support member 16 and cleaning the transparent plate 155.
- the number of transparent plates 155 is smaller than that of lamps 153, and the surface is more flat, making cleaning easier. Therefore, the downtime due to maintenance can be shortened.
- the lamp 153 has a reduced illuminance due to long-term use, and needs to be replaced. Even in such a case, the present invention is simple if the light source unit 15 is removed from the support member 16 and replaced with the spare light source unit 15. The removed light source unit 15 can be used as a new spare part by replacing the lamp 153 in a wide area outside the apparatus.
- the light source unit 15 can be easily replaced with a completely different lamp such as a high pressure mercury lamp from a black light, for example.
- the material was 100% cotton, the thickness of the warp and weft was 10th cotton, and the fabric was 144 warp Z-inch and 78 weft Y-inch.
- This equipment had an irradiation intensity of 2.2 WZcm 2 , an irradiation time of about 25 minutes, and a running (processing) speed of the cloth of 1.3 m / min.
