Mixture, with 200 turns/min stirring 3 minutes, sodium chloride and ammonium hydrogen carbonate sufficiently dissolved, and formed the satiety of sodium chloride-containing crystal
With salt lysate, then it is added into the supersaturated salt lysate of sodium chloride-containing crystal and accounts for the dye of dye liquor mass ratio 0.05~0.5%
Material, stirs evenly, and forms the dye liquor of sodium chloride-containing crystal and dyestuff micella group, is added accounts in the dye liquor of the group of micella containing dyestuff backward
The highly polar solvent n,N-dimethylacetamide of dye liquor gross mass mass ratio 10~50% was mixed with 200 turns/min stirring 3 minutes
It closes uniformly, n,N-dimethylacetamide acts on dyestuff micella group, and dyestuff micella group releases dyestuff unimolecule, is formed and has high pole
The stand-by dye liquor of property.
B) it dyes
High-performance textile to be contaminated and prepared highly polar stand-by dye liquor are put into the dyeing cup with sealing function, it is closed, it rises
Temperature keeps the temperature 60min to 70-90 DEG C, and under temperature action, ammonium bicarbonate breaks down generates atmospheric carbon dioxide and ammonia, titanium dioxide
Carbon increases pressure in dyeing cup confined space voluntarily, and ammonia, which is dissolved in water and is formed, has polar ammonium hydroxide, and ammonium hydroxide acts on high-performance
Fabric surface makes high-performance textile surface active, meanwhile, n,N-dimethylacetamide and sodium chloride crystal are complexed, and generate activity
Chlorine, Active Chlorine open the part hydrogen bond between the macromolecular that high-performance textile fiber surface has activated, and form channel and hole, dyestuff
Unimolecule is by contaminating high-performance textile on channel and hole.
