Problems solved by technology

Diacetate is suitable for low temperature conditions and has poor thermal stability
[0003] The disclosed disperse dye composition of patent application number CN 102964875A (a kind of red disperse dye composition) has high brilliance, a high lifting rate, and a wide application range. However, when this disperse dye composition is applied to triacetate fiber, the lifting rate is not good , poor compatibility and color synchronization between compositions, especially extremely sensitive to temperature, unstable dyeing process

Embodiment 1

[0037] The disperse dye composition that is used for triacetose of the present embodiment is prepared according to the following steps:

[0038] Weigh components A, B, C, and D according to the raw materials and proportions in Table 1, and mix them uniformly to obtain mixture 1, then weigh the additives according to the raw materials and proportions in Table 3, and add them to the mixture 1. Mix evenly to obtain mixture 2. Add water to the mixture 2 and grind and disperse it with a sand mill to obtain a disperse dye composition for triacetose; wherein, the mass ratio of the auxiliary agent to the dye part is 3:7.

Embodiment 2

[0040] The disperse dye composition for triacetose of the present embodiment is different from Example 1 in that: after grinding and dispersing, spray drying is carried out to obtain a powdery disperse dye composition; the process conditions of spray drying are: inlet temperature The temperature is 125°C, and the outlet temperature is 60°C. After drying, a disperse dye composition with a particle size of 1 μm is obtained.

Embodiment 3

[0042] The disperse dye composition for triacetose of this embodiment differs from that of Example 2 in that: the spray drying process conditions are: inlet temperature 130°C, outlet temperature 60°C, after drying, the particle size is 0.5 μm disperse dye composition.

Abstract

The invention discloses a disperse dye composition used for cellulose triacetate fibers, particularly relates to a disperse dye composition without a chemical reaction and belongs to the field of dye. The dye part of the disperse dye composition comprises, by mass, 1-45 parts of component A, 1-35 parts of component B, 25-75 parts of component C and 0.1-2 parts of component D. When the disperse dye composition used for cellulose triacetate fibers is adopted for dyeing, a navy dyed fabric which is beautiful in color, good in fastness to rubbing and excellent in light fastness and other fastness can be obtained; in this way, the disperse dye composition is economic and environmentally-friendly disperse red dye which has excellent dyeing performance.

Description

technical field [0001] The invention relates to an organic dye, in particular to a disperse dye composition without chemical reaction. Background technique [0002] Disperse dyes are a class of non-ionic dyes with low water solubility. They were first used in the dyeing of acetate fibers and are called acetate dyes. Acetate fiber is divided into diacetate and triacetate. Diacetate is suitable for low temperature conditions and has poor thermal stability. Triacetate fiber can be dyed under high temperature conditions, and has good thermal stability. Acetate dyes are very sensitive to temperature, when the dyeing temperature is uneven or high, it will cause poor appearance or color bloom. At present, acetate dyes are widely noted in the market. Generally, disperse dyes are used on acetate, and diacetate can only be dyed under low temperature conditions, while triacetate can be dyed under high temperature conditions, but currently There are almost no high-temperature disper...
