Abstract

The effect of surface morphology of poly(ethylene terephthalate) (PET) film on the detergency of particulate soil was investigated as functions of surfactant concentration, ionic strength, electrolytes type, washing time and particle size. The PET surface film was modified with NaOH and dimethylformamide (DMF) for different times. Generally, the removal of particles from the PET film treated with NaOH and DMF was relatively higher than that of nontreated film in both nonyl-phenol polyoxyethylene ether and sodium dodecyl-benzene sulfonate solution. The removal of particles from the film increased with increasing concentration of surfactant and ionic strength regardless of treated condition, but the effects of electrolytes type, washing time and particle size on the removal of particle from the PET film varied with treated condition such as chemical type (NaOH or DMF) and treatment time. The removal of ${\alpha}-Fe_2O_3$ particles from the PET film treated with NaOH and DMF were better related with surface energies than surface roughness and surface area. The correlation coefficient between the removal of particle from the film and adsorption of surfactants to film was 0.9.
