In this work we aimed our focus at the determination of the zeta potentials of a standard fabric of cotton Empa type (dyed, finished and softened), which was washed in the presence of surfactants and of a copolymer of action DTI - dye transfer inhibition agent -. The copolymer DTI the type VI/PVP, was used. The washing with ecological surfactants such as: a sodium dodecylbenzene sulfonate (LAS) mixed with an non-ionic alkylpolyglucoside (APG) was made. The cotton fabric was dyed with three different direct dyes (with different molecular weights), finished by the resin of DMDHEU (dimethylol dihydroxy ethylene urea) and softened with a microemulsionated compound of ammo-niumsilicone. The variation of zeta potential of cotton articles was obtained under the influence of the total concentration and the proportion of mixture of the surfactants anionic with non-ionic, and of these separately. The polymer DTI stayed to constant concentration, when mixing it with the surfactants. The variation of the zeta potentials of the cotton undyed and finished in function of the DTI were obtained.
