In the previous reports, one of the authors has reported that poly(vinyl alcohol) (PVA) shows an excellent anti-soil-deposition action for various fabrics as studied in a model soiling bath containing fabric, surfactant and carbon black particles. In this report the mechanism of anti-soil-deposition of PVA is investigated. The amounts of adsorbed PVA onto carbon black particle and fabrics (cotton or polyester), and the anti-soil-deposition efficiency for the fabrics, were measured in the above soiling bath devoid of surfactant. It is concluded that the action is not ascribed to PVA adsorbed on the fabrics but to that adsorbed on carbon black particle, of which more than 10 percent of the surface area is covered with PVA.
