Semiconductor Laser Dyeing of Meta-type Aramid Fabrics

Kiyoshi Miura; Kunihiko Imada; Katsuhide Odagi

In the previous paper, we reported the new dyeing method of using laser dyeing equipment for dyeing aramid fabrics with disperse dyes and vat dyes using an infrared rays absorber. The new findings reported in this paper are as follows ; 1) We found the existence of many kinds of vat dyes that have absorption in the infrared region, and using these type of vat dyes it is possible to dye aramid fiber without using infrared absorber material. 2) It was found that the temperature on the surface of the fiber caused by the laser irradiation reached 350-400deg. 3) It was found that the aramid fiber can be dyed by using vat dyes at the temperature of about 350deg using an electric furnace.
