Embodiment 1

[0074] According to the content ratio of each component whose dye number is 1 in Table 3, accurately weigh 55 grams of A1, 25 grams of B1, 15 grams of sodium sulfate, and 5 grams of MF, and mix well to obtain the red dye of the present invention.

[0075] The amount of each component in Table 3 is represented by the percentage immediately following it, and the percentage refers to the mass percentage of the quality of each component in the total mass of the dye; The compounds are described in Table 1, and the compounds indicated by the B1-B5 numbers of component B are described in Table 2.

[0076] Accurately weigh 10 grams of nylon / cotton knitted fabric (the mass ratio of cotton is 70%, and the mass ratio of nylon is 30%) according to the dye consumption of 2% o.w.f, and accurately weigh 0.2 grams of the dyestuff in the present embodiment. The dyeing bath ratio is 1:10, according to figure 1 Dyeing is carried out in the dyeing and finishing process, wherein the consumption ...

Embodiment 2-10

[0078] According to the preparation method of Example 1, with reference to the ratio of each component in Table 3, corresponding dyes with dye numbers 2-10 were prepared respectively. With reference to the dyeing and finishing process in Example 1, corresponding nylon-cotton dyed fabrics can be obtained respectively.

Abstract

The invention discloses a red dye, mainly composed of 20%-80% of A component and 5%-60% of B component, characterized in that the A component is shown in formula 1, the The B component is shown in formula 2. The invention also discloses a preparation method and application. The invention can realize one-bath one-step dyeing of nylon / cotton and nylon / rayon fabrics, obtain better uniformity of the same color, greatly improve the production efficiency of nylon / cotton and nylon / rayon fabrics, save dyeing time, and reduce energy consumption , Reduce sewage discharge.

Description

technical field [0001] The invention belongs to the field of dye preparation, and in particular relates to a red dye, a preparation method and an application thereof. Background technique [0002] In recent years, with the development of fashion and people's continuous demand for high-quality fabrics, nylon / cotton fabrics (woven or knitted) or nylon / rayon elastic fabrics are increasingly favored by consumers. However, due to the limitations of dyes and dyeing processes, the printing and dyeing of nylon / cotton fabrics is usually carried out using the two-bath method, which leads to long processing cycles, low production efficiency, large energy consumption, serious environmental pollution, and high production costs. [0003] In order to solve these problems, many institutions and factories in the industry are exploring the feasibility of one-bath and one-step dyeing of nylon / cotton fabrics. However, the existing commercial dyes on the market are difficult to meet this requir...
