Dyes are compounds that can impart bright and durable colors to other substances in a molecular or dispersed state. In the printing and dyeing process, besides using raw dye powder, dye auxiliaries are also added to enhance dyeing efficiency and effectiveness. Among these auxiliaries, dye dispersants play a vital role. Dye dispersants are non-ionic surfactants that aid in achieving a leveling effect, maintaining dye dispersion, preventing aggregation and precipitation, and improving dye solubility. By incorporating dispersants and protective colloids, uniform dyeing is ensured, and stains are prevented.
