Example Embodiment

[0030] Example 1

[0031] Take 3g meta-aramid fabric, use CIDisperse Red 54 as the dye, and prepare the dye solution in a 400ml dye cup with a volume of 400ml with a capacity of 1:20 according to the liquor ratio. N,N-dimethylethyl in the dye solution The mass percentage of amide is 10%, the mass percentage of sodium chloride is 5%, the mass percentage of ammonium bicarbonate is 0.4%, the mass percentage of distilled water is 84.55%, and the mass percentage of dye is 0.05%. First, put sodium chloride and ammonium bicarbonate in distilled water. Stir at 200 rpm for 3 minutes in the medium, the sodium chloride and ammonium bicarbonate are fully dissolved, then add N,N-dimethylacetamide and dye, stir at 200 rpm for 3 minutes, the dye solution is evenly mixed, and finally The meta-aramid fabric is put into the dyeing cup, sealed, heated to 70°C, kept for 60 minutes, drained, washed, and dried to obtain a dyed meta-aramid fabric. The effect is shown in Table 1.

Abstract

The invention relates to a high-performance fabric self-pressurization carrier dyeing method and belongs to the technical field of textile printing and dyeing. According to the method, carbon dioxideand ammonia gas generated by thermal decomposition of ammonium bicarbonate are utilized in the dyeing process of a high-performance fabric, the carbon dioxide enables the pressure intensity in a closed space of a dyeing cup to be increased, the solubility of the ammonia gas to rise and the amount of formed ammonia water to be increased, the polarity of the ammonia water is strong, the surface activity of fiber can be changed, and it is facilitated that the active chlorine generated by the complexation effect of N,N-dimethylacetamide and sodium chloride acts on the high-performance fiber, the hydrogen bonding force among macromolecular chains of the fiber is weakened, and the porosity of the fiber is improved. The N,N-dimethylacetamide has strong polarity under the low temperature dyeing condition of 70-90 DEG C, the dissolving concentration of dye can be effectively improved, the micelle concentration of the dye is reduced, the dye molecules are easy to adsorb and dye the high-performance fabric, and the dyeing efficiency of the high-performance fabric is effectively improved. In addition, the method can achieve a better dyeing effect at a relatively low dyeing temperature, and theproduction cost and the energy consumption are reduced.
