Abstract

Provided are an environmental protection-type liquid bromo indigo dye composite addition auxiliary agent and a preparation method therefor. The addition auxiliary agent comprises the following ingredients, by weight, 10-40% of dispersants, 5-20% of polycarboxylate derivatives, 2-10% of chelating agents, 5-20% of anionic surfactants, 2-10% of nonionic surfactants, 0.05-0.2% of antifoaming agents, and 30-80% of deionized water. The environmental protection-type composite addition auxiliary agent of liquid bromo indigo dyes can improve storage dispersion stability of liquid bromo indigo dyes remarkably, and raises the dye-uptake rate and dye utilization rate of bromo indigo dyes during denim dyeing, and the amount of dyes can be decreased when the same dyeing degree is achieved.

Description

technical field [0001] The invention relates to an environment-friendly liquid bromoindigo dye composite additive and a preparation method thereof, belonging to the field of fine chemicals. Background technique [0002] Brominated indigo dye is an indigo vat dye obtained by brominating and modifying indigo dye. It is mainly used for the dyeing of denim clothing. Compared with indigo dye, it has higher dyeing rate, brighter and brighter color, light fastness and Good wear resistance and other advantages, with good development potential. [0003] At present, commercial brominated indigo dyes are mostly in the form of powder, which has problems such as serious dust pollution and high energy consumption in high-temperature spray drying during production, inconvenient chemical metering during dyeing, and poor batch dyeing stability. Making dyes in liquid form can solve these problems. With the improvement of production automation of printing and dyeing enterprises, the establis...
