Abstract
The effects of surfactants and concentration of NaOH in surfactant solution on the removal of free fatty acid soil from cotton fabrics were investigated. Cotton fabrics were soiled with palm itic acid which is the most common fatty acid found in natural oily soil and washed in Lauder-ometer with various types of surfactant with or without NaOH. The rate of soil removal was estimated by analyzing palmitic acid contents in fabric before ar d after washing. Analysis of palmitic contents was made by extracting palmitic acid with azeotropic mixture of alcohol-benzene and the extracts were titrated with standard NaOH solution. It was shown that the types of surfactant are important factor in free fatty acid removal and the efficiency increases in the following order: SLS
