Problems solved by technology

[0004] The above-mentioned patent also has the following disadvantages: during the long-term use of the composite reactive brown dye, one component of the dye composition, disperse blue 79, is more sensitive to alkali and temperature, and its composition has poor reproducibility. The phenomenon of shifting is obvious, resulting in low practicability of complex reactive brown dyes

Abstract

The invention belongs to the technical field of dyes, particularly relates to reactive brilliant yellow dye and composite reactive brown dye, and provides the following scheme aiming at the problem that the migration phenomenon is obvious due to the fact that the dye is too sensitive to temperature: the reactive brilliant yellow dye comprises a component A shown in a formula (I) and a component Bshown in a formula (II), and M in the formula (I) and the formula (II) is independently H, Na, K or Li; the formula (I) accounts for 6-12% of the mass of the reactive brilliant yellow dye; and the formula (II) accounts for 80-90% of the mass of the reactive brilliant yellow dye. The reactive brown dye composition improves the color development and dyeing performance of commercial reactive dyes, improves the dye uptake and fixation rate of the dyes and improves the product quality through a compounding synergistic technology and by utilizing the compounding deepening effect of the three dyes, and has the advantages of stable performance, high solubility, good dyeing synchronism and good tone reproducibility.

Description

technical field [0001] The invention relates to the technical field of dyes, in particular to a reactive brilliant yellow dye and a composite reactive brown dye. Background technique [0002] With the improvement of living standards, consumers have further requirements for the comfort and functionality of clothing fabrics. Among them, pure cotton fabrics have been favored by consumers for their strong hygroscopicity, good heat preservation, excellent heat resistance, and high comfort. However, pure cotton fabrics still have shortcomings such as easy to wrinkle, easy to shrink, easy to change, and not acid-resistant, which limits their application. At present, the development of nylon-cotton interwoven fabrics is very popular in the market. Its advantages are: luster Bright, full-feeling, comfortable to wear, cool and breathable, good elasticity, anti-wrinkle and wear-resistant, and good drape, it is the first choice for high-end clothing fabrics. Based on this, specific dyes...
