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 5% reactive dye solution by mass percentage, 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%; the sample of 1 g of cotton fabric was immersed in a ratio of 1:15 In the reactive dye liquid encapsulated by reverse micell...

[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; a certain amount of Levafix Red CA reactive dye is dissolved in a small amount of water to make 0.5ml of a 7% reactive dye solution by mass percentage, and the reactive dye solution is slowly injected into the reverse micelles solution. 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; the sample of 1 g of cotton fabric was immersed in the reverse glue with a bath ratio of 1:10. In the reactive dye solution encapsulated by bundles, the containe...

Abstract

The invention relates to a fabric non-water dyeing method. The method comprises the following steps: pre-mixing a nonionic surfactant and a co-surfactant, dissolving the mixture into an organic solvent to prepare a reversed micelle solution; slowly adding an active dye solution into the reversed micelle solution, at the same time, stirring the solution until the turbid reversed micelle solution becomes clear to obtain a reversed micelle encapsulated active dye solution; soaking fabrics in the reversed micelle encapsulated active dye solution, vibrating the dye solution continuously to carry out adsorption dyeing at a constant temperature until a balance of adsorption dyeing is reached; adding a color fastening agent solution to obtain reversed micelle encapsulated fastening agent solution; and vibrating the solution continuously so as to fix the color of fabrics at a constant temperature. The fabrics are dyed by a one bath method based on a nonionic surfactant. The cost is reduced, and the dyeing effect is guaranteed. At the same time, an organic solvent is taken as the medium; the using amount of water is reduced, moreover, the organic solvent can be recovered effectively, and the environmental pollution is reduced.

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 the existing dyeing techniques, reversemicelle 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 ...
