The invention belongs to the technical field of textile auxiliary and fine chemistry and specifically relates to an antistatic printing and dyeing auxiliary. The auxiliary is prepared from the following components in percentage by weight: 35% of water-based thickening agent, 35% of water-soluble growth substance, 25% of emulsion mixture and 5% of sterilizing mould-proof auxiliary, wherein the thickening agent comprises 25% of reactive dye and 75% of mixture of natural, semi-synthetic and synthetic water-soluble polymers; the mixture is prepared from 25% of water, 25% of natural water-soluble polymer, 30% of semi-synthetic water-soluble polymer and 20% of synthetic water-soluble polymer; the water-soluble growth substance is prepared from 25% of reducing agent, 35% of wetting agent, 25% ofemulsifier, 15% of dispersing agent and a mixture thereof. By adopting the reactive dye, the antistatic printing and dyeing auxiliary has the advantages of wide color spectrum, bright color, excellentperformance and strong applicability; by mixing three different kinds of thickening agents and properly adjusting the proportion, the antistatic printing and dyeing auxiliary can be adapted to the printing and dyeing states in different conditions.
