There have been two supposition that the decrement of fatty soil removal at high temperature was caused by surfactants and by the structure of fibers and Fabrics. To study the effect of temperature on the removal of fatty soil, the following variables were selected: Sodium n-alkylsulfates having various chain lengths of alkyl groups as surfactants, cotton and cuprammonium rayon as cellulose fibers having different fiber structure, and two types of soil having different melting points. Experiment was carried out with radiotagged soil and detergency was estimated by liquid scintillation counting. The results were as following: the detergency of tripalmitin on cotton was increased with elevating temperature up to $60\~70^{\circ}C$ and decreased above $70^{\circ}C$ regardless of alkyl chain length of sodium n-alkylsulfates. In distilled water without surfactant, the detergency of tripalmitin on cotton was also decreased above $70^{\circ}C$, but the detergency of tripalmitin on cuprammonium rayon was not decreased above $70^{\circ}C$. effects seemed to be caused by fiber structure. Though the melting point of mixture of tripalmitin and dodecane was lower than that of tripalmitin, the optimum and decrement temperature of detergency were not altered. Finally the results of this study were shown that the surfactant and characteristics of soil did not affect on the mode of detergency vs temperature, but the fiber structure.
