The structure of these surfactants were confirmed by FT-IR and the surface activities were evaluated surface tension, contact angle, foaming properties, pH buffer, emulsion. We have also studied the dispersing abilities of these surfactants toward commercial disperse dye from particle size, dispersibilites of the dye solutions and dying. We found A.B surface tension results exhibited that surfactants have lower surface tension, moreover, these compound have better wetting and lower foaming. The results showed that this surfactant can add dyes with smaller particle size. There are dyes that dye-surfactant complexes (complex) the existence of polyester fabric dyeing, add the surfactant will produce retarding phenomenon and when heating process can reduce dyed rate, avoiding the phenomenon of uneven dyeing. It is dye – surfactant has complexes so can promote the solubility of disperse dyes. However, the research also discusses how different parameters affect the dye – surfactant interaction. The study uses Taguchi method First, this method was adopted to carry out the parameter design, and the interaction parameters that would affect the absorbance of UV–visible spectrum could be predicted as the control factors.
