Abstract

The soil removal versus washing time curves were analyzed by the method of approximating to the kinetic equation in which a computer enabled an automatic change of the order. Polyester films and polyester mesh screens were used as flat substrate and clothes like substrate respectively, and palmitic acid was used as an oily soil model. Used parameters were the initial removal rate (DINIT) which correlates with the removal force of the system, and the recurrent order (Nc) which correlates with the decrease of the removal rate with the time elapsed.
1) In both cases of using soiled films and soiled mesh screens, Nc of the foam washing (parallel fixed type) was close to Nc of the immersion washing, and DINIT of the former was 3 to 5 times of the latter.
2) The foam washing (vertically fixed type) of the soiled mesh screen gave greater DINIT than that of the parallel fixed type and gave less Nc than that of the other types of washing. These results suggest that the action of bubbling sorption affects the function of carrying out of the soil from the inner portion of the substrate to the phase of wash liquid.
