The adsorption of cationic surfactant is influenced by many factors, such as temperature, concentration, pH and the mechanical action in stirring. The influences of these factors on the repeated adsorption of cationic surfactant to cotton cloth were investigated. The adsorption quantity increased with the increase of ζ-potential and the concentration of cationic surfactant.Up to 40℃ the adsorption quantity increased and decreased above this temperature. Desorption quantity of cationic surfactant increases with the increase of temperature. In the repeated adsorption using only cationic surfactant the adsorption amount decreased with the increase of treatment times. It also decreased in the run which washing treatment by water was inserted between the adsorption and the next adsorption of cationic surfactant. But it increased in the run which the treatment by anionic surfactant and the washing treatment by water were inserted between the adsorption and the next adsorption. The contribution of anionic surfactant to the increase of adsorption quantity of cationic surfactant may be conceivable.
