시판 세제를 사용하여 세척 조건에 따른 인공오염포의 세척성

Abstract

Formulations of compact and supercompact heavy-duty detergents, which are being used widely around thecompact detergents and the conventional detergents. The compact detergents have a higher content of surfactants, oxy-gen bleach and enzymes than the conventional detergents. We have studied to find the most effective washing conditionsof artificially soiled cloths with a commercial, supercompact, heavy-duty detergent and a drum type washing machinewhich is becoming the preferred type in Korea. Moreover, we have studied the washing performance with an impellertype washing machine, which has heretofore been the most popular type in East Asia. With the drum-type washingmachine, washing performances improved as the washing temperatures went up and the washing times were lengthened.Though the rate of soil removal with a double recommended dosage was higher than with the recommended amount at20oC, the effects of the higher dosage decreased as the washing temperatures increased. Finally, the washing per-oC. The washing performances at 40oC with the rec-ommended dosage for 90 minutes were the same as with the double recommended dosage for 45 minutes. The soilremoval efficiencies with the impeller-type washing machine were much lower than those of the drum-type washingmachine. The reasons for this were the higher bath ratio that led to the lower concentration of wash liquor, the shorterwashing time, and the lower washing temperature.
