Problems solved by technology

[0002] Although environmentally friendly dyes have restrictions on the content of harmful substances to the human body, most of them only control the environmental protection of textile fabrics, that is, to measure the dyes on textile fabrics and control the content of harmful substances. The high content of harmful substances in the products has caused the sewage and sludge of the printing and dyeing factory to seriously exceed the environmental protection requirements and affect the ecological environment
At the same time, due to different textile printing and dyeing processes, or different amounts of dyes, the content of harmful substances in textiles is also different, so that printing and dyeing wastewater, sludge and some textile fabrics that do not meet environmental protection requirements have caused great harm to downstream printing and dyeing factories. Loss
For example, C.I. Disperse Red 153 is a red disperse dye with bright color and excellent sublimation fastness, light fastness and washing fastness, but the chlorophenylchlorotoluene is high, and chlorophenylchlorotoluene is carcinogenic and harmful to human body, soil and environment. Both are more dangerous

preparation example 1

[0049] (1) Distill 3,4-dichloroaniline in hydrogen chloride solution to obtain 3,4-dichloroaniline hydrochloride solution, then thiourea with ammonium thiocyanate, and close the ring under concentrated sulfuric acid to obtain 2- A sulfuric acid solution of amino-5,6(6,7)-dichlorobenzothiazole;

[0050] (2) Add nitrosylsulfuric acid to the sulfuric acid solution of 2-amino-5,6(6,7)-dichlorobenzothiazole, keep stirring at 35°C for 1 hour, drop into sulfuric acid acidity of 46%, and the temperature is Diazotization reaction in dilute acid at -5~-2°C, dropwise addition time is 5 hours, and keep warm for 2 hours after dropping to obtain diazo component;

[0051] (3) Add water, sulfuric acid, and Pingping to the coupling kettle, add the coupling component N-ethyl-N-cyanoethyl m-toluidine, stir for 30 minutes, add ice and isooctyl alcohol, and control the temperature at -5~ 0°C, add the diazo component dropwise, dropwise for 2.5 hours, control the temperature at 0-5°C and keep it wa...

preparation example 2-5

[0053] The method of Preparation Example 1 was adopted, except that the coupling component N-cyanoethyl-N-acetoxyethylaniline in Preparation Example 1 was replaced by the coupling components shown in Table 1.

[0055]

[0056] Components A contained in the products (I-2)-(I-5) obtained in sequence from Preparation Examples 2-5 are compounds of formulas (1-2)-(1-5) in sequence.

Embodiment 1

[0064] 100 grams of product (I-1), 100 grams of dispersant MF, 95 grams of lignin 85A, and 440 grams of water were added to fully stir, grind with a sand mill, and then spray dry to obtain a disperse dye composition.

Abstract

The invention discloses a disperse dye composition as well as a preparation method and application thereof. The disperse dye composition contains a component A, a prohibited aromatic amine compound, chloridized phenol, chlorobenzene and chlorotoluene, optional auxiliaries and other inevitable impurities, wherein the component A contains one or more compounds of formula (1) as shown in the specification. Various environment-friendly indexes meet the requirements of Bluesign, in addition, the single contents of the prohibited aromatic amine compound (AZO), the chloridized phenol (CPs) and the chlorobenzene and chlorotoluene (COCs) and the total content of the chlorobenzene and chlorotoluene in the chemical product of the disperse dye composition are low. In addition, after being dyed, a fabric can meet infant-grade requirements of Oeko-Tex Standard 100 (2016). Sewage generated after dyeing can also meet environment-friendly requirements, and meanwhile, the disperse dye composition can be relatively convenient, rapid and safe to use.

Description

technical field [0001] The invention relates to a disperse dye composition and its preparation method and application. The disperse dye composition is suitable for dyeing and printing of polyester and its blended fabrics. Background technique [0002] Although environmentally friendly dyes have restrictions on the content of harmful substances to the human body, most of them only control the environmental protection of textile fabrics, that is, to measure the dyes on textile fabrics and control the content of harmful substances. Therefore, there are still dyes used in dyeing. The high content of harmful substances in the products has caused the sewage and sludge of the printing and dyeing factory to seriously exceed the environmental protection requirements and affect the ecological environment. At the same time, due to different textile printing and dyeing processes, or different amounts of dyes, the content of harmful substances in textiles is also different. In this way,...
