This study was designed to investigate the relationship between adsorption of surfactant to $\alpha-Fe_{2}O_{3}$ particles and removal of the particles from fabric in anionic/nonionic surfactant mixed solution. The adsorption of anionic surfactant to particle increased with increasing surfactants concentration but the influence of surfactant concentration was small in the case of nonionic surfactant. The adsorption of nonionic surfactant to particle increased with decreasing ionic strength, while the influence of ionic strength on the adsorption of anionic surfactant to particle was small. The removal of $\alpha-Fe_{2}O_{3}$ particle from PET fabric was relatively higher in anionic/nonionic surfactant mixed solution than in both single surfactant solutions, where it increased with decreasing ionic strength and surfactant concentration. Generally the removal of $\alpha-Fe_{2}O_{3}$ particle from PET fabric increased with increasing adsorption of nonionic surfactant to the particle. Although some deviations exist, the removal of $\alpha-Fe_{2}O_{3}$ particle from PET fabric in anionic/nonionic surfactant mixed solution was related not to the adsorption of anionic surfactant to the particle but to the adsorption of nonionic surfactant.
