QUICK DYEING AND DEEP DYEING METHOD WITH NATURAL INDIGO AND INDIGO DYE

摘要

PROBLEM TO BE SOLVED: To provide a quick dyeing and deep dyeing method with a natural indigo or an indigo dye, which is capable of improving deep dyeing effect on a textile structure for a short time by carrying out a heat-treatment process in an alkaline dye bath in the presence of a dihalogenotriazine compound having a hydrophilic substituent group and a natural indigo or an indigo dye, achieving the shortening of the dyeing process time by the natural indigo and the indigo dye compared with the conventional dyeing process with a natural indigo or an indigo dye, improving the efficiency of dyeing process, suppressing the thermal energy, and reducing the consumption of the dye and a reducing agent in the dyeing by the oxidation reduction function of the natural indigo and the indigo dye and the quantity of exhaust water (biochemical oxygen demand).;SOLUTION: The method for quick dyeing and deep dyeing of a textile structure includes a heat-treatment process at 20-80°C in an alkaline dye bath in the presence of a dihalogenotriazine-based compound having a hydrophilic substituent group and a natural indigo or an indigo dye.;COPYRIGHT: (C)2009,JPO&INPIT
