Problems solved by technology

[0012] At present, many existing chelating and dispersing agents have poor chelating and dispersing effects. For example, many chelating and dispersing agents chelate color-developing metal ions such as Fe3+, Cu2+, and Zn2+ temporarily. Metal ions are also released, so that sensitive colors such as emerald blue, brilliant blue, sapphire blue, and brilliant green are aggregated under the induction of metal ions, resulting in color blooming.
In addition, many existing chelating dispersants are not biodegradable, will pollute the environment, and are toxic to the human body.

Abstract

The invention discloses an efficient chelating dispersant and an application method thereof. The efficient chelating dispersant is prepared from, by mass, 50-80 parts of modified polyacrylic acid substances, 10-30 parts of organic phosphate and 10-20 parts of alcohol amine substances. The application method of the chelating dispersant includes: (1) in a polyester cotton blend dyeing process, consumption of the chelating dispersant is 0.5-1.5g / L, and the chelating dispersant is added in an initial dyeing stage; (2) in a vat-dye cotton dyeing process, consumption of the chelating dispersant is 0.5-2g / L, and the chelating dispersant is added before adding of an alkaline agent; (3) in a reactive-dye or direct-dye cotton dyeing process, consumption of the chelating dispersant is 0.5-2g / L, and the chelating dispersant is added in an initial dyeing stage; (4) in a reactive-dye dyeing and printing after-soaping or continuous pad dyeing process, consumption of the chelating dispersant is 0.5-1g / L. The efficient chelating dispersant is high in chelating force and dispersion force and great in chelating and dispersion effect.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, and relates to a high-efficiency chelating dispersant and an application method thereof. Background technique [0002] Chelating dispersant, also known as: complexing agent, chelating agent, metal ion blocking agent, water softener, etc. The compound formed by the combination of chelating dispersant and metal ion with only coordination bond but no covalent bond is called a complex, and the compound formed by both coordination bond and covalent bond is a chelate. [0003] Chelating dispersants are widely used in the textile printing and dyeing industry, and can be used as auxiliary agents in pre-dyeing, refining, bleaching, dyeing, soaping and other processes. [0004] The dyeing and finishing industry has the following requirements for chelating dispersants: [0005] 1. Efficient chelation, dispersion and suspension. [0006] 2. It has good complexation effect u...
