Embodiment 1

[0040] In this embodiment, the nonionic surfactant is polyethylene glycol-12-tridecyl ether, that is, R in the molecular formula 1 for H, R 2 for linear C 13 Alkyl, n is 12. At room temperature, pre-mix 0.0175mol of n-octanol and 0.0025mol of non-ionic surfactant in a beaker by stirring, the ratio is 7:1, and dissolve them in 15ml of n-octane after mixing to make reverse Micellar solution; a certain amount of Levafix Red CA reactive dye is dissolved in a very small amount of water to make 0.5ml of a reactive dye solution with a mass percentage of 5%, and the reactive dye solution is slowly injected into the reverse micellar solution. After vigorously stirring for 2 minutes at a rotating speed, the solution was clarified to obtain a reactive dye solution encapsulated in reverse micelles, wherein the mass ratio of the reactive dye to 1 gram of fabric was 2.5%; a sample of 1 g of cotton fabric was immersed in a ratio of 1:15 In the reactive dye liquid encapsulated by reverse m...

Embodiment 2

[0042] In this embodiment, the nonionic surfactant is polyethylene glycol-12-tridecyl ether, that is, R in the molecular formula 1 for H, R 2 for linear C 13 Alkyl, n is 12. At room temperature, pre-mix 0.0156mol of n-octanol and 0.0024mol of non-ionic surfactant in a beaker by stirring, the ratio is 6.5:1, and dissolve in 10ml of n-octane after mixing to make a reverse glue Beam solution; Dissolve a certain amount of Levafix Red CA reactive dye in a small amount of water to make 0.5ml of a reactive dye solution with a mass percentage of 7%. Slowly inject the reactive dye solution into the reverse micellar solution, and force it under 800rpm after injection. After stirring for 5 minutes, the solution was clarified to obtain a reactive dye solution encapsulated by reverse micelles, wherein the reactive dye was 3.5% by mass compared to 1 gram of fabric; In the reactive dye solution encapsulated by bundles, the container of the reactive dye solution encapsulated by the reverse...

Embodiment 3

[0044] In this embodiment, the nonionic surfactant is polyethylene glycol-12-tridecyl ether, that is, R in the molecular formula 1 for H, R 2 for linear C 13 Alkyl, n is 12. At room temperature, pre-mix 0.018mol of n-octanol and 0.0024mol of non-ionic surfactant in a beaker by stirring, the ratio is 7.5:1, mix and dissolve in 13ml of n-octane to make a reverse glue Beam solution; a certain amount of Levafix Red CA reactive dye is dissolved in a very small amount of water to make 0.5ml of a reactive dye solution with a mass percentage of 3%, and the reactive dye solution is slowly injected into the reverse micellar solution. After vigorously stirring for 5 minutes, the solution was clarified to obtain a reactive dye solution encapsulated by reverse micelles, wherein the reactive dye was 1.5% by mass compared to 1 gram of fabric; Immerse in the reactive dye solution encapsulated in reverse micelles, and vibrate the container filled with the reactive dye solution encapsulated ...

Abstract

The invention relates to a fabric non-aqueous dyeing process, which comprises: premixing a nonionic surfactant and an auxiliary surfactant, and dissolving them in an organic solvent to prepare a reverse micellar solution; mixing the reactive dye solution Slowly inject in the reverse micelle solution and keep stirring until the reverse micelle solution changes from turbidity to clarification to obtain the reactive dye liquid encapsulated by reverse micelles; the fabric is immersed in the reactive dye liquid encapsulated by reverse micelles and Continuously vibrate at a constant temperature for adsorption dyeing until the adsorption dyeing reaches equilibrium; add a fixative solution to obtain a fixative solution encapsulated in reverse micelles, and continuously vibrate at a constant temperature to achieve color fixation on the fabric. The invention adopts the one-bath method based on nonionic surfactant to dye the fabric, which can guarantee the dyeing effect while reducing the cost; at the same time, the organic solvent is used as the medium, which can reduce the water consumption, and the organic solvent can be effectively recycled, reducing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a fabric non-aqueous dyeing process. Background technique [0002] The dyeing process of textiles is usually carried out in aqueous medium, but the water-based dyeing method and the subsequent washing process will cause adverse impacts on the environment, such as the discharge of chemical pollutants and a large amount of colored wastewater. So people try to introduce a new concept of avoiding excessive water in dyeing technology, and in recent years are also researching dyeing technology that does not use water as a solvent. [0003] Among existing dyeing techniques, reverse micelle-encapsulated dyes in organic solvents have attracted attention as an alternative dyeing process, which can be used to reduce water consumption while also contributing to uniform dyeing. Most of the reverse micelles used in the fabric dyeing process are composed of anionic surfactants, especially dio...
