Detergency and soil redeposition of wool fabric in 8 nonionic surfactants (Span 20, 40, 60, 80/Tween 20, 40, 60, 80) and 4 solvents (water, petroleum, perchloroethylene(PCE), decamethylcyclopentasiloxane(D?)) were studied. Detergency of wool fabric in water was very low with and without surfactants due to the low wetting and difficulty in penetration of water into the fabric. Lipophilic surfactants improved the detergency of wool fabric in petroleum solvent and PCE. The detergency of wool fabric in D? was similar to that in petroleum solvent without surfactants. When water was solubilized, Span 20 addition to petroleum solvent and PCE increased the detergency of wool fabric. The detergency for D? was improved with solubilized water, however, it was lowered when the surfactants were added to the system. Therefore, it is important to formulate appropriate detergents which have good solubility and affinity to silicone for D? charge system. Hydrophilic surfactants were effective for water and lipophilic surfactants were effective for petroleum solvent and PCE in soil redeposition prevention of wool fabric. The soil redeposition prevention effects are not found in D? with both Span 20 and Tween 20. The same tendency of results in soil redeposition of wool fabric is observed when water is solubilized.
