Embodiment 1
[0050] a. Weigh 19.5 grams of A4 dye, 68 grams of B1 dye, and 12.5 grams of the following formula (3), and then weigh 110 grams of auxiliary agent 85A.
[0051] Formula (3)
[0052] b. Add 300 grams of water, grind together in a sand mill for about 3 hours, and then spray dry. The resulting powder must be easily dispersible and soluble in water.
[0053] c. Weigh 0.2 grams of the above obtained powder and 200 milliliters of water to form a solution in a steel cup, adjust the pH value to between 4.5 and 5 with glacial acetic acid, put 10 grams of polyesterfiber material into the prepared solution, and use conventional The high-temperature and high-pressure dyeing process was carried out at 130°C for 50 minutes, and then the orange sample was obtained after cooling, washing, rinsing, and drying.
[0054] d. The above-mentioned dye powder sample and the dyed polyester fiber material sample were tested together for pentachlorophenol and tetrachlorophenol, and the results ...
Embodiment 2
[0056] a. Weigh 31.5 grams of A3 dye, 68.4 grams of B1 dye, 0.1 gram of B6 dye, and then weigh 100 grams of auxiliary agent 85A.
[0057] Repeat the above b, c, d operations, the dye powder sample and the dyed orange polyester fiber material sample are tested together for pentachlorophenol and tetrachlorophenol, and the obtained results are all "ND".
Embodiment 3
[0059] a. Weigh 45.73 grams of A4 dye, 54.27 grams of B1 dye, and then weigh 100 grams of auxiliary agent 85A.
[0060] Repeat the above b, c, d operations, the dye powder sample and the dyed orange polyester fiber material sample are tested together for pentachlorophenol and tetrachlorophenol, and the obtained results are all "ND".

Abstract
The invention discloses a disperse dye mixture. The disperse dye mixture comprises, by mass, 10-99% of one or more ingredients A which are compounds shown in the formula (I) and 1-90% of one or more ingredients B which are compounds shown in the formula (II). The disperse dye mixture is especially suitable for polyesterfiber and ultrafine polyesterfiberdyeing, has the characteristics of high dye uptake and good deep-dyeing property, does not contain pentachlorophenol and tetrachlorophenol and satisfies environmental protection requirements.
Description
technical field [0001] The invention relates to the field of textiles, in particular to a disperse dye mixture and a preparation method and application thereof. Background technique [0002] In recent years, with the implementation of new environmental protection standards, the environmental protection requirements of textiles have been continuously improved, and the requirements for pentachlorophenol and tetrachlorophenol have also been continuously improved. [0003] Hazards of pentachlorophenol (PCP) and tetrachlorophenol (TeCP): This product can cause abnormal hyperactivity of the body's basal metabolism and high fever. Generally, it is caused by a large amount of skin absorption or accidental ingestion, and it mostly occurs in summer. Often preceded by fatigue, sweating, polydipsia, dizziness, headache, palpitations, fever of about 38 ℃, may be accompanied by nausea, vomiting, abdominal pain and so on. The condition suddenly intensifies within a few hours, with high f...
