The color was measured using a Minolta colorimeter CR200. Then add 20 to this
Turn on one W SE fluorescent lamp and one BLB fluorescent lamp and irradiate them with an ultraviolet intensity meter at an intensity of 2 mW/cm2 for 10 minutes, then measure the color tone with a Minolta CR200 and compare it with the color tone before the light irradiation. Color difference was calculated. Also, after irradiating with light, place it in a dark place.
The color was measured in the same manner when the sample was left to stand for a period of time, and the color difference from the color tone before light irradiation was measured.

うメリットがある。Further, the photochromic nylon fiber of this example has a skin color and becomes tan brown when irradiated with light. Therefore, the fabric made from the photochromic nylon fiber of the present invention is flesh-colored and becomes tan-colored when irradiated with light. If you make a doll using this, you can make a tanned doll. Furthermore, when used as a bandage, it has the advantage of being inconspicuous because it is close to the skin color.
