We studied the dyeing of meta-type aramid fabrics with pigment-state vat dyes and disperse dyes using semiconductor laser. After printing the paste which involved infrared rays absorber, semiconductor laser was irradiated for a short time. As a result, it was found that each dye penetrated into the inside of the fiber, and that dyeing was possible with the comparative good result of dyeability and fastness. And then, we made continuous laser thermosol dyeing equipment using semiconductor laser experimentally.
