Embodiment 1

[0262] Dyeing brocade / viscose (50 / 50) blended roman cloth with dye composition of the present invention

[0263] Dye composition A (black)

[0264]

[0265] Dyeing recipe:

[0266]

[0267] The dye composition A and brocade / viscose blended fabrics are dyed at room temperature (35°C), and sodium sulfate, leveling agent, sodium bicarbonate, accelerator, etc. are added in sequence, and then the temperature is raised to 70°C for dyeing (according to 1.5°C rate) and keep warm for 20 minutes, continue to heat up to 98°C for dyeing (heating at a rate of 1°C per minute) and keep warm for 40 minutes. After dyeing, cool down to 80°C, and use low-temperature soaping agent to soap for 15 minutes. See the dyeing process flow chart figure 2 :

[0268] After dyeing, the fabric was visually evaluated, and it was found that the dyeing was relatively uniform and the dyeing depth was good. At the same time, the dyed fabrics were tested for fastness, and the results are recorded in Ta...

Abstract

The invention provides a dye composition for one-bath and one-type based dyeing and a dye method of the dye composition. The dye composition is used for blending nylon / cotton, nylon / Nien linen and interlacing a fabric. The composite comprises active azo dyes of three or more types and / or transmit metal complex dye compound of three or more types under the ratio of 1:2. The dye composition used in match with the general assistant can successfully and effectively carry out the one-bath and one-type method of light colour, neutral colour, deep colour and even black colour. The dye composition comprises one or more specified active dyes provided by the invention, and one or more metal complex dye under the ratio of 1:2. By adopting the dye composition, the implemented dyeing technology has the following characteristics: the one-bath and one-type method is carried out, so that the operation is simple and convenient, and great reproducibility is realized; the dyeing effects of light colour, neutral colour and deep colour, especially the black colour are provided; great homochromatism of nylon / cotton, and nylon / Nien linen dyeing is provided; and the colour fastness is excellent; and compared with the conventional technology, the dyeing method provided by the invention has the advantages of water saving, energy conservation, time saving, and emission reducing.

Description

technical field [0001] The invention relates to a one-bath one-step dyeing dye composition and a dyeing method thereof, especially a one-bath one-step dyeing dye composition and a dyeing method for nylon / cotton, nylon / viscose blended or interwoven fabrics. Background technique [0002] Nylon / cotton, nylon / viscose blended and interwoven fabrics have the excellent performance of both nylon fiber and cellulose fiber. Nylon / cotton and nylon / viscose fabrics have both the good moisture absorption and breathability of cellulose fiber and the good elasticity of nylon , Excellent wear resistance. The fabric feels plump, smooth, comfortable to wear, elastic and glossy, and is currently a popular clothing fabric. [0003] Nylon fiber and cellulose fiber have different molecular structures, so their dyeing processes are also different. The traditional dyeing method of nylon cotton, nylon viscose blended and interwoven fabrics adopts two-bath dyeing method of acid / reactive and acid / dir...
