Must be removed mechanically (use hand) not need to be washed. Held on textile by electrostatic forces: lint, dust. Soak in water with or without some agitation. Detergent- helps process of moving oil from textile to water. Surfactant( surface active agent) type of detergent- reduce water surface tension. Serve as a bridge between oil and water: ex:soap is made by basic hydrolysis (by naoh) of animal fats. Alkali part creates hydrophilic: ex: o in hard water containing more calcium and magnesium. Coo react with ca or mg, and generate insoluble . Cooca and coomg a detergent builder is needed when laundering in hard water.
