<p>PURPOSE:To obtain the subject apparatus, equipped with a dye bath having a temperature regulator, monitoring part for sensing and displaying pH of a dye liquor, dye concentration and quantity of the liquor and controlling part for pH, quantity of the liquor, etc., based on sensed signals and capable of improving productivity with hardly any dispersion of quality. CONSTITUTION:The pH of a dye liquor 2, dye concentration and quantity of the liquor in a dye bath 1 equipped with a temperature regulator 3 are displayed as a signal (S1) of a liquor quantity meter 4 in the dye bath, a signal (S2) of a dye concentration meter 8 and a signal (S3) of a pH meter 9 in a monitor 10 and the above-mentioned signals are then inputted to a controlling part 11 to operate feed pumps 12, 13 and 14 by the controlling part 11 based on the afore-mentioned signals. Prepared solutions are automatically fed from tanks 15, 16 and 17 respectively containing an aqueous solution of an acid, water and dye liquor into the dye bath 1 to control the dyeing process with a higher accuracy. Thereby, e.g., a high-quality color separation filter with hardly any dispersion of dyeing is efficiently produced at a low cost.</p> |
