Embodiment 1
[0049] a. Weigh 19.5 grams of A4 dye, 68 grams of B1 dye, and 12.5 grams of the dye of the following formula (3), and then weigh 110 grams of auxiliary agent 85A.
[0050]
[0051] 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 dispersed and dissolved in water.
[0052] c. Weigh 0.2 g of the above-obtained powder, 200 ml of water, convert it into a solution in a steel cup, adjust the pH value to between 4.5-5 with glacial acetic acid, take 10 g of polyester fiber material and put it into the prepared solution, use conventional The high temperature and high pressure dyeing process was kept at 130 °C for 50 minutes, and then the orange samples were obtained after cooling, washing, rinsing and drying.
[0053] d. The above dye powder samples and the dyed polyester fiber material samples were tested for pentachlorophenol and tetrachlorophenol, and the obtained results were all "ND".
Embodiment 2
[0055] a. Weigh 31.5 g of A3 dye, 68.4 g of B1 dye, 0.1 g of B6 dye, and 100 g of auxiliary agent 85A.
[0056] Repeating the above b, c, d operations, the dye powder samples and the dyed orange polyester fiber material samples were tested for pentachlorophenol and tetrachlorophenol, and the obtained results were all "ND".
Embodiment 3
[0058] a. Weigh 45.73 grams of A4 dye, 54.27 grams of B1 dye, and 100 grams of auxiliary agent 85A.
[0059] Repeating the above b, c, d operations, the dye powder samples and the dyed orange polyester fiber material samples were tested for pentachlorophenol and tetrachlorophenol, and the obtained results were all "ND".

Abstract
The invention discloses a preparation method of an orange disperse dye. The preparation method comprises the following steps of 1, mixing ingredients according to a certain ratio, carrying out crushing granulation treatment and carrying out spraying drying, or 2, respectively carrying out crushing granulation treatment on all the ingredients, mixing the treated ingredient granules according to a certain ratio and carrying out spraying drying. The orange disperse dye comprises, by mass, 10-99% of an ingredient A and an ingredient B. The ingredient A comprises one or more compounds shown in the formula (I) and the ingredient B comprises one or more compounds shown in the formula (II). The dye mixture obtained by the preparation method is especially suitable for polyester fiber and ultrafine polyester fiber dyeing, has the characteristics of high dye-uptake and good deep-dyeing properties, 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 preparation method of an orange disperse dye. Background technique [0002] In recent years, with the implementation of new environmental protection standards, the environmental protection requirements of textiles have been continuously improved, among which the requirements for pentachlorophenol and tetrachlorophenol are also increasing. [0003] Hazards of Pentachlorophenol (PCP) and Tetrachlorophenol (TeCP): This product can cause abnormal hyperactivity of the body's basal metabolism and high fever. Generally due to a large amount of skin absorption or accidental ingestion, it mostly occurs in summer. Fatigue, sweating, polydipsia, dizziness, headache, palpitations, and fever of around 38°C are often preceded by nausea, vomiting, and abdominal pain. Within a few hours, the condition suddenly intensifies, with high fever (above 40°C), profuse sweating, extreme fatigue, irritability,...
