Abstract | PURPOSE:To obtain the subject meta-type aramid fiber deeply dyed and excellent in color fastness by adding a benzenecarboxylic acid ester to a cationic dye- containing dye liquor and dyeing the fiber with the resultant dye bath. CONSTITUTION:A dye bath is prepared by adding a benzenecarboxylic acid ester to a cationic dye-containing dye liquor and a meta-type aramid fiber (polymetaphenylene isophthalamide-based fiber) is dyed (130 to 170 deg.C) by using the dye bath. Thereby, a deep dyed fiber especially excellent in colorfastness to light is obtained. As the benzenecarboxylic acid ester, dimethyl terephthalate, dimethyl phthalate, etc., are preferably used. |
