Abstract

The invention discloses a waterless cotton fabric dyeing process. The process comprises the following procedures: a. soaking a cotton fabric into a NaOH water solution; b. drying the cotton fabric by adopting hot air; c. spraying a diacetyl ethanol solution onto the cotton fabric; d. atomizing a coloring agent and spraying the coloring agent onto the cotton fabric; e. enabling the cotton fabric to stand for three hours in an environment with relative air humidity above 50%; f. aeration-drying the cotton fabric, wherein the coloring agent is a decamethylcyclopentasiloxane suspension system comprising one or a mixture of more than two of the type X of dichloro-s-triazinyl, the type K of chloro-s-triazinyl, the type KN of vinyl sulfuryl and the type M of multi-active groups. The process has the beneficial effects that the coloring agent is atomized and then sprayed onto the cotton fabric, thus avoiding the problem of low coloring agent utilization rate caused by traditional soaking, bleaching and dyeing; the process has the advantages of good dye adsorption effect, high dye uptake and dyeing uniformity.

Description

technical field [0001] The invention relates to a fabric dyeing process, in particular to a waterless cotton fabric dyeing process and a waterless dyeing device. Background technique [0002] At present, the dyeing of cotton fiber is mainly carried out in water medium with reactive dyes. The specific dyeing process is as follows: firstly, the dye particles (0.02g) are dissolved in non-ionized water (the bath ratio is 1:20) at room temperature to prepare the dye solution, slowly warming up to 90°C. After the temperature reached 90°C, the timing was started and untreated fabric (1 g) was added to the dye liquor. After 10 minutes, add half of sodium sulfate (0.6g) and keep stirring the fabric to make it fully and evenly contact with the fabric. After another 10 minutes, add the remaining half of sodium carbonate (0.6g) and continue stirring. After another 10 minutes, add sodium carbonate (0.4 g). Finally, it was incubated for another 30 minutes to complete the dyeing. Post-...
