Embodiment 1

[0063] (1) 16.7 grams of dye A with general formula (Ia), 11.9 grams of dye B with general formula (IIg) and 15.3 grams of dye C with general formula (IIIa) were mixed with 500 milliliters of water and 50 grams of lignosulfonate The sodium bicarbonate was ground together in a sand mill for 3 hours, and then spray-dried (inlet temperature 130°C, outlet temperature 60°C) to obtain dye mixture 1. The resulting powder dye (about 100 g) was easily dispersed in water.

[0064] (2) 0.4 g of the above-prepared powder dye mixture 1 was dyed with 10 g of polyester textile material by conventional HT printing and dyeing method at pH = 4.5 and 130 ° C for about 45 minutes, washed, rinsed and dried to obtain a fairly good The fastness performance of the dyeing sample 1 of red brilliant navy blue.

Embodiment 2

[0066] 1) Condensation of 24 grams of dye A of general formula (Ib), 22 grams of dye B of general formula (IIe) and 7 grams of dye C of general formula (IIIa) with 300 grams of water and 47 grams of naphthalenesulfonic acid formaldehyde Grinding together, according to the preparation method of Example 1 and drying to obtain dye mixture 2.

[0067] (2) According to the dyeing method of Example 1, when 0.4 g of this dye mixture was used to dye polyester fiber fabric, dyeing sample 2 with reddish brilliant (bloomy) black was obtained.

Embodiment 3~10

[0069] (1) 8.5 grams of dyestuff A with general formula (Ia) and 40.1 grams of dyestuff with general formula (II) (wherein various substituents are defined in Table 1), with 300 milliliters of water and 51.4 grams of lignosulfonic acid Sodium is ground together, according to the preparation method of embodiment 1, makes dyestuff mixture 3~10.

[0070] (2) According to the dyeing method of Example 1, when 0.4 gram of this dye mixture is used for dyeing polyester fiber fabrics, jet black and bright dyed samples 3 to 10 are obtained.

Abstract

The invention relates to the technical field of dyes. As people pay more attention to the safety and health of textiles currently, the invention discloses a dispersed azo dye mixture and application of the azo dye mixture to solve the problem that organochlorine dyeing carriers are present in the textiles. The dispersed azo dye comprises the following components by weight parts: 1-40 weight partsof dye A, 1-49 weight parts of dye B, 0-60 weight parts of dye C, and 20-89 weight parts of dispersant. After dyeing with the dye mixture of the invention, no organochlorine dyeing carrier is detected in polyester fiber and the dyeing effect is not affected.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to a disperse azo dye mixture and its application. Background technique [0002] Affected by the trend of advocating healthy life in Europe, consumers have questioned the safety and health of textiles when purchasing textiles. In order to regulate the safety of textiles, the European Union, the United States, Japan and China have carried out relevant research and testing and certification of harmful substances. Among them, the more influential ones are the "Eco-label" of the European Union and the "Ecological Textile certification Oeko-Tex 100" two major standards. Ecological textile certification Oeko-Tex100 has become the most recognized standard because it better takes into account the requirements of the market and producers. [0003] The inspection of organo-chloride dyeing carrier is one of the routine test items of ecological textiles at present. Organo-chloride carrier is...
