Efficiency of dilute emulsion washing for oily soil was examined. First, washing test with test fabric soiled with oily soils using Terg-O-Tometer was performed in dilute emulsion system of surfactant / higher alcohol / water. The results show that emulsion washing was more effective than the washing by simple surfactant aqueous solution in the case of non-polar and medium-polar oily soil. On the other hand, the washing efficiency of the emulsion system for high polarity oily soil was lower than that of surfactant solution. As for the carbon number of higher alcohol, detergency of oily soils was increased as the carbon number increased more than 7. Surface tension measurement showed that the surface tension of emulsion system is lower than that of surfactant solution. This fact indicates that the high detergency of the emulsion system for non-polar oily soil and medium polar oily soil was largely due to the increased interfacial activity relevant to emulsification or rolling up.

The local deformation of flared skirts made of 14 different kinds of fabrics under the clothing's own weight was measured by the circular stamp method and examined through analysis of a 3-way ANOVA test. Additionally, the influence of the mechanical properties of fabrics on the local deformation were investigated by the multiple regression analysis. The results were as follows: 1)The results of the 3-way ANOVA test indicated that the local deformation of the skirts changed significantly with each factor, that is fabric (the largest deformation being in silk satin and the least one in broadcloth), row (2nd>3rd≒1st>4th) and column (side> middle>center); 2) As a result of the multiple regression analysis with variables of each fabric and explanatory variables of the KES value, the deformation of the 1st row was explained by the tensile characteristic, that of the 2nd and 3rd rows of the left and right side was explained by the shearing characteristic, and the intermediate position was explained mainly by the bending characteristic, and that of the 4th row was explained by the weave density; 3) The local deformation of the left and right side line was different in the bias texture, and this was considered to be the cause of the twist of the flared skirt side line.
