Energy-saving and emission-reducing assistant for printing and dyeing and production method thereof

Abstract

The invention relates to an energy-saving and emission-reducing assistant for printing and dyeing, which comprises an assistant 1 and an assistant 2, wherein the assistant 1 comprises the following components in parts by weight: methylpyrrolidone, diacetone alcohol, salethyl, isopropyl salicylate and lauryl azone; and the assistant 2 comprises the following components in parts by weight: rare earth oxide, oxalic acid, water and ammonium carbonate. The production process of the assistant 1 comprises the steps of: adding the methylpyrrolidone in a reaction vessel, raising the temperature and then adding the diacetone alcohol, the salethyl,the isopropyl salicylate and the lauryl azone, reacting under the condition of preserving the temperature until the pH value is 6-6.5, and finally obtaining the assistant 1. The production process of the assistant 2 comprises the steps of: adding the oxalic acid and the water into the rare earth oxide La2O3, and then stirring with a high-speed stirring machine, adding the ammonium carbonate and the water, then stirring for 3-6min at a high speed, standing, and storing in a dark place.

Description

technical field [0001] The invention belongs to the field of printing and dyeing, in particular to an energy-saving and emission-reducing auxiliary agent for printing and dyeing and a production process thereof. Background technique [0002] Some existing printing and dyeing auxiliaries, due to the low coupling rate of dye groups and fibers, the low adsorption rate of dye molecules on fibers, and poor stability, resulting in slow dyeing speed, uneven dyeing, swelling and level dyeing of fibers poor effect. The low adsorption rate of the dye molecules also resulted in significantly higher concentrations in the foot water. Contents of the invention [0003] The object of the present invention is to design an energy-saving and emission-reducing auxiliary agent for printing and dyeing and its production process. [0004] What the present invention is to solve is that some existing printing and dyeing auxiliaries, due to the low coupling rate of the dye group and the fiber, t...

[0004] What the present invention is to solve is that some existing printing and dyeing auxiliaries, due to the low coupling rate of the dye group and the fiber, the low adsorption rate of the dye molecule on the fiber, and poor stability, lead to slow dyeing speed, uneven dyeing, and watery feet. The problem of obviously high concentration, poor swelling and leveling effect on fibers
