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 dosage of the three primary colors is according to the ratio of the color tower diagram shown in Figure 1. Adjust the pH of the dye solution with acetic acid to 6~7, enter the dyeing at 40°C, raise the temperature to 100°C, and dye for 40 minutes, 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 shown in Figure 2. The washing fastness of ...

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 made in Switzerland are shown in Figure 4. The washing fastness of ...

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 present invention discloses a method with dispersed paint micro-capsule dyeing textile for micro-capsule dispersion and color matching, including melamine resin pre-polymer or polyurethane as wall material to make the dispersed pain micro-capsule, which is used to carry out rope dyeing on polyester or nylon textiles, without leveling agent, dispersant, penetrating agent and etc. The method is characterized in that: the dispersed paint micro-capsule employs three primary colors dispersed paint capsule, namely, the red dispersed paint micro-capsule, yellow dispersed paint micro-capsule and blue dispersed paint micro-capsule, which can perform color matching on polyester or nylon textiles. Through the dosage control of the red, yellow and blue paint micro-capsules, varieties of colors can be painted on textiles, with firm color fixation; the technology is simple and meets the requirements of even dyeing, dispersion and dyeing transfer; the dyeing temperature is low, so energy consumption during dyeing is saved.

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...
