The removal behavior of ${\alpha}-Fe_2O_3$ and carbon black particles from surface-modified PET[poly(ethylene terephthalate)] films were investigated as functions of surfactant concentration and type. Moreover, the ${\zeta}$-potential, the potential energy between particles and film, and the adsorption of surfactants to the film were examined as detergent environments. The function of the two-step plasma treatments of $O_2$ and $O_2+CHF_3$ was to impart hydrophilicity and hydrophobicity to PET film respectively. The negative ${\zeta}$-potential of the film, the potential energy between the particles and film, and the adsorption of surfactants by the film increased with the two-step plasma treatment of $O_2$ and $O_2+CHF_3$. Generally, the removal of ${\alpha}-Fe_2O_3$ particles from the modified PET film was higher than that of carbon black particles. However, the removal behaviors of ${\alpha}-Fe_2O_3$ and carbon black particles were different depending on the surface property of the PET films. There was no difference in the removal behavior between ${\alpha}-Fe_2O_3$ and carbon black particles in the hydrophilic film; however, there was a significant difference between behaviors of the two particles in the hydrophobic film. With ${\alpha}-Fe_2O_3$ particles having a high surface charge, the removal of particles from the film increased with increasing film hydrophobicity. On the other hand, in the case of low surface charge carbon black particles, their removal from the film decreased with increasing film hydrophobicity.
