Effects of poly (vinyl alcohol) (PVA) on deposition of oily soils onto polyester fabrics have been investigated. The anti-deposition effects of PVA was remarkably influenced by its saponification degree rather than polymerization degree. A marked effect of anti-deposition was found for the partially saponified poly (vinyl acetate) (PVAc). The adsorption properties of PVA on polyester fiber and oily soils were strongly affected by the residual acetate groups in PVA. These results suggested that the anti-deposition effects of the fully saponified PVAc were due to its adsorption on polyester fiber, and those of the partially saponified PVAc was attributed to its adsorption on oily soils.
