Embodiment 1

[0025] A microcapsule disperse black, which is formed by mixing three microcapsule disperse dyes of blue, purple and orange in a mass ratio of 1:1:1; the blue, purple and orange microcapsule disperse dyes are made of etherified melamine resin. The microcapsule wall material monomer uses blue, purple, and orange disperse primary color dyes as core materials respectively, and adopts in-situ polymerization to prepare blue, purple, and orange microcapsule disperse dyes. The average particle size of the microcapsules is 15-40 μm.

[0026] The preparation method of above-mentioned microcapsule dispersion black is:

[0027] Cut 20Kg of disperse blue primary dye, 0.4Kg of emulsifier (0.1Kg of fatty alcohol polyoxyethylene ether T07, 0.1Kg of polypyrrolidone, 0.2Kg of sodium lignosulfonate), and 330Kg of water in a high-speed shearing machine for 20-30min , adjust the pH=3~4; pump it into the reaction kettle, add 10Kg of the etherified body of I monomer dropwise at 20°C, and then rais...

Embodiment 2

[0033] A microcapsule disperse black, which is formed by mixing three microcapsule disperse dyes of blue, purple and orange in a mass ratio of 0.75:0.75:1; the blue, violet and orange microcapsule disperse dyes are made of etherified melamine resin. The microcapsule wall material monomer uses blue, purple, and orange disperse primary color dyes as core materials respectively, and adopts in-situ polymerization to prepare blue, purple, and orange microcapsule disperse dyes. The average particle size of the microcapsules is 15-40 μm.

[0034] The preparation method of above-mentioned microcapsule dispersion black is:

[0035] Cut 20Kg of disperse blue primary dye, 0.6Kg of emulsifier (0.4Kg of disodium lauryl sulfosuccinate monoester, 0.2Kg of Pingpingjia), 180Kg of water in a high-speed shearing machine for 30min, and adjust the pH to 3-4; It was pumped into the reaction kettle, and 15Kg of the etherified body of monomer I was added dropwise at 30°C, and then the temperature wa...

Embodiment 3

[0040] A microcapsule disperse black, which is formed by mixing three microcapsule disperse dyes of blue, purple and orange in a mass ratio of 0.60:0.83:1; the blue, violet and orange microcapsule disperse dyes are made of etherified melamine resin. The microcapsule wall material monomer uses blue, purple, and orange disperse primary color dyes as core materials respectively, and adopts in-situ polymerization to prepare blue, purple, and orange microcapsule disperse dyes.

[0041] The preparation method of above-mentioned microcapsule dispersion black is:

[0042] Cut 20Kg of disperse blue dye, 0.5Kg of emulsifier (0.01Kg of sodium carboxymethyl cellulose, 0.29Kg of Pingpingjia, 0.2Kg of maleic acid copolymer), and 288Kg of water in a high-speed shearing machine for 30min, and adjust PH=3 ~4; pump into the reaction kettle, add 12.5Kg of the etherified body of I monomer dropwise at 30°C, and then raise the temperature to 58°C. After the dropwise addition, raise the temperature...

Abstract

The invention relates to a microcapsule disperse black and the manufacture method and the coloring method for superfine synthetic fiber and the fabric. It uses etherification melamine resin as microcapsule wall material monomer, blue, purple, orange three dispersing primary color as core material to make blue, purple, and orange three microcapsule dispersing dye, and mixing the dyes according to 1-0.5:1-0.5:1-0.5 to form microcapsule disperse black. The invention could dye to gain pure black, and the dyed waste water could be recycled after simple filtering.

Description

technical field [0001] The invention belongs to the technical field of light chemical industry, and in particular relates to a microcapsule disperse black, a preparation method thereof, and a method for dyeing ultrafine synthetic fibers and fabrics thereof. Background technique [0002] The printing and dyeing industry has a large amount of wastewater discharge, serious pollution, and difficult governance, which restricts the development of the industry. Previously, inventors such as Chen Shuilin had invented a method for preparing disperse dye microcapsules (CN 03116243.6), a method for dyeing disperse dye microcapsules (CN 03116244.4) and a method for dyeing disperse dyes without washing (CN 200410054220.9). These technologies clearly show that the use of microcapsule technology to prepare disperse dye microcapsules can achieve non-auxiliary, pollution-free and water-free dyeing, which provides an effective path for clean production in the printing and dyeing industry. ...
