Problems solved by technology

At present, more dyes can not meet the requirements in terms of performance, especially in the category of superfine fiber fabrics. At present, there are no dyes of special items, and in order to achieve the effect, the prior art can only be achieved through several processes. Practice dyeing, and the rate of excellent products is not high

[0026]

[0027] Described component C, its structural formula (III) is as follows:

[0028]

[0029] Described component D, its structural formula (IV) is as follows:

[0030]

[0031] According to the above-mentioned component distribution ratio, each component is weighed for proportioning, crushed and granulated. In this step, glass balls are used as the grinding medium for grinding, and the glass balls are ground and filtered; the...

Embodiment 2

[0033] Superfine fiber high light fastness dye, mix the following components respectively, component A: 34%, component A is disperse orange 29#, component B: 10%, component B is disperse red 167#, component C: 14%, component C is disperse blue 60#, component D: 38%, component D is disperse blue 56#. The dispersant has a lignin content of 4% to form a black color dye composition, the molecular formula of which is shown in Example 1. According to the above component distribution ratio, each component is weighed for proportioning, crushed and granulated. In this step, glass balls are used as the grinding medium for grinding, and the glass balls are ground and filtered; the diameter of the glass balls is 1-2 μm. Spray drying or drying in an oven, the inlet temperature of spray drying is 110°C, and the outlet temperature is 60°C. Then add dispersant and stir in the blending equipment for 1 hour until the diffusion level reaches level 4. Dry blending is carried out at a temperature...

Embodiment 3

[0035] Superfine fiber dye with high light fastness, mix the following ingredients separately, component A: 30%, component A is disperse orange 29#, component B: 15%, component B is disperse red 167#, component C: 14%, component C is disperse blue 60#, component D: 38%, component D is disperse blue 56#. The dispersant MF content is 5%, and the black color dye composition is formed, and the molecular formula is as shown in Example 1. According to the above component distribution ratio, each component is weighed for proportioning, crushed and granulated.

Abstract

The invention belongs to the technical field of dyes and relates to disperse dye composition, in particular to a superfine fiber dye with high light fastness and a preparation method thereof. The superfine fiber dye with the high light fastness comprises components in percentage by mass as follows: 30%-34% of disperse orange 29# serving as a component A, 10%-15% of disperse red 167# serving as a component B, 14%-18% of disperse blue 60# serving as a component C, 38%-42% of disperse blue 56# serving as a component D and the balance of a dispersing agent. Compared with the prior art, the superfine fiber dye with the high light fastness has the advantages as follows: the dye composition is prepared in the specific mixing ratio, each component has higher fastness, so that the performance of the components after combination is not changed, the comprehensive performance is improved, data such as sublimation fastness, washing fastness and the like are correspondingly improved, besides, an idiomatic mode of the industry is adopted for dyeing, dyed fabric with full hue can be obtained, further, the consumed time is shorter, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of dyes, and relates to a disperse dye composition, in particular to a superfine fiber dye with high light fastness. Background technique [0002] Disperse dyes are a class of non-ionic dyes with low water solubility. It was first used for the dyeing of acetate fiber, known as acetate dye. With the development of synthetic fibers, nylon and polyester have appeared one after another, especially polyester, because of its high alignment, less fiber voids, and strong hydrophobicity, it is necessary to expand the fiber with a carrier or under high temperature and thermal melting, so that the dye can enter Fiber and dyed. With the rapid development of polyester new fibers in recent years and the increase in people's demand for textiles, correspondingly, the dyeing performance and environmental protection performance of the dye itself have also put forward historically high requirements, requiring dyes to have hi...
