Composite printing and dyeing auxiliary as well as preparation method and application of auxiliary

The invention relates to a composite printing and dyeing auxiliary as well as a preparation method and an application of the auxiliary. The composite printing and dyeing auxiliary is prepared by compounding polyethylene glycol diamine, N-methylol acrylamide, sodium dodecyl benzene sulfonate, ammonium persulfate, di-rhamnolipid, a plant extract, tannic acid, sodium taurate, 1-carboxyl-N,N,N-trimethyl polycrylactone, tetradecyl dimethyl ammonium chilride, 1-phenoxy-2-propyl alcohol, 2-p-toluene sulfonic acid phenylamino-4-chloro-6-beta-naphthoxy triazine, silicon dioxide, europium chloride, ethanol and polyethylene glycol 600. As specific polymer components, the plant extract, quaternary ammonium salt, natural amino acid and natural esters are introduced, a rare earth complex is formed and other suitable components are added under compounding and synergistic effects, the composite printing and dyeing auxiliary has excellent technical effects of burnishing, protecting the color and improving the color fastness, and has the certain antibacterial and antistatic functions, and therefore, the composite printing and dyeing auxiliary has a wide industrial application prospect in the textile printing and dyeing industry.
