Embodiment 1

[0020] Weigh 5g of nylon 66, put disperse dye microcapsules (core-wall ratio CW=1:1) into the dyeing bath by 2% of the fabric weight, disperse dye microcapsules C.I. disperse red 60, C.I. disperse yellow 54, C.I. disperse blue 56 The amount of three primary colors according to figure 1 The ratio shown in the color column diagram, adjust the pH of the dye solution with acetic acid to 6~7, enter the dyeing at 40°C, heat up to 100°C, dyeing time is 40min, and then quickly cool down to 60°C. Take out the fabric, filter the dye solution and then pour it into the dyeing cup, put the taken out fabric into the solution, raise the temperature to 80°C, keep it warm for 10 minutes, cool down, take out the fabric, wash it in cold water, and dry it in the air. The K / S values ​​of the dyed fabric at different wavelengths measured by the Datacolor SF600 Plus CT color measuring and matching instrument produced in Switzerland are as follows: figure 2 shown. The washing fastness of the dyed ...

Embodiment 2

[0023] Weigh 5g of polyester fabric, put disperse dye microcapsules (CW=1:3) into the dyeing bath by 6% (omf) of fabric weight, disperse dye microcapsules C.I. Disperse Red 60, C.I. Disperse Yellow 54, C.I. Disperse Blue 56 The amount of the three primary colors is matched according to the color tower diagram, the pH of the dyeing solution is adjusted to 4~5 with acetic acid, the dyeing is carried out at 10°C, the temperature is raised to 130°C, the dyeing time is 30min, and then the temperature is quickly cooled to 60°C. Take out the fabric, filter the dye solution and then pour it into the dyeing cup, put the taken out fabric into the solution, raise the temperature to 70°C, keep it warm for 15 minutes, cool down, take out the fabric, wash it with tap water, and dry it. The K / S values ​​of the dyed fabric at different wavelengths measured by the Datacolor SF600 Plus CT color measuring and matching instrument produced in Switzerland are as follows: Figure 4 shown. The washi...

Embodiment 3

[0026] Weigh 5g of polyester fabric, put disperse dye microcapsules (CW=1:2) into the dyeing bath by 10% (omf) of fabric weight, disperse dye microcapsules C.I. Disperse Red 73, C.I. Disperse Yellow 211, C.I. Disperse Blue 183 The dosage ratio of the three primary colors is 4:5:1, the pH of the dye solution is adjusted to 4-5 with hydrochloric acid, the dyeing is carried out at 20°C, the temperature is raised to 85°C, the dyeing time is 50min, and then the temperature is rapidly lowered to 60°C. Take out the fabric, pour the dyeing solution into the dyeing cup after filtering, put the taken out fabric into the solution, raise the temperature to 85°C, keep it warm for 20 minutes, cool down, take out the fabric, wash it fully with tap water, and dry it in the air. The K / S value measured at λ=450nm by Datacolor SF600 PlusCT color measuring and matching instrument is 16.004. The washing fastness of the fabric is grade 5, the light fastness is grade 6-7, and the wet and dry frictio...

Abstract

The invention discloses a method for color matching of microencapsulated disperse dyes for dyeing fabrics with disperse dye microcapsules, which comprises disperse dye microcapsules prepared by using melamine resin prepolymer or polyurethane as wall materials, using the disperse dye Dye microcapsules are used for rope-like dyeing of polyester or nylon fabric without leveling agent, dispersant, penetrating agent and other auxiliary agents. , Yellow microcapsules of disperse dyes, blue microcapsules of disperse dyes, can color-block polyester or nylon fabrics, by controlling the amount of disperse dye microcapsules of red, yellow, and blue primary colors, various colors can be dyed on fabrics, coloring It is firm; the process is simple, fully meeting the requirements of leveling, dispersing and dyeing; and the dyeing temperature is low, which saves energy consumption in the dyeing process.

Description

technical field [0001] The invention belongs to the technical field of light chemical industry, relates to a method for dyeing fabrics with disperse dyes, in particular to a method for dyeing fabrics with disperse dye microcapsules. Background technique [0002] The printing and dyeing industry plays an important role in my country's economic and social development, but the industry has not yet got rid of the situation of high pollution, high water consumption, and high energy consumption. The transformation of the social and economic development model requires printing and dyeing enterprises to change the current Due to the current situation, dyeing and finishing workers in various countries are trying to find new dyeing methods to reduce water consumption and reduce sewage discharge. At present, it is well known in the technical field that microencapsulated disperse dyes have excellent slow-release function, can effectively control the dyeing speed, and can achieve the proc...
