Anti-deposition ettects of detergent builders in washing process have been investigated. On the basis of the chemical and interfacial interactions of builders with oily soils (oleic acid and triolein) and, the amount of soils deposited onto polyester fabric, the effects of the builders on the anti-deposition of the oily soils are classified into three groups.
(1) Neutral builders have no effect because of their weak adsorption on oily soil.
(2) Alkaline builders have the effect of anti-deposition more or less because of their strong adsorption on oily soil.
(3) Poly (vinyl alcohol), a nonionic polymer, has a remarkable effect of anti-deposition because of its adsorption on both of the oily soils and the fabric.
