Abstract
The antiredeposition of oily soil by Zeolite has been studied under various aqueous conditions, sodium dodecyl sulfate, sodium silicate, sodium carbonate, sodium carboxymethyl cellulose, sodium sulfate and a synthetic detergent. Oleic acid and oleyl alcohol were used as model substances of oily soil. The reflectivity of cotton cloth to which the oily soil adhered was identical with the original, in spite of the addition of Zeolite. In the case of nylon cloth, reflectivity increased with the amount of Zeolite added. That is, the amount of oily soil adhering to the nylon cloth surface decreased with the amount of Zeolite. Thus, in the case of nylon, the antiredeposition of oily soil was concluded due to the Zeolite.
