Factors which affect the Detergency of Sodium Oleate Solution

Abstract

In order to estimate the influence of ten factors which may contribute to the detergency of fabrics in Na oleate solution, a series of experiments was carried out with artificially soiled pieces of cotton and polyester cloth. Statistical analyses of 252 cases were conducted by the multiple correlation method by the use of TOSBAC-3400.
The results obtained are as follows :
1. The multiple correlation coefficient for the detergency and ten factors was 0.606 for cotton and 0.950 for polyester.
2. Comparing the standardized weight vectors of ten factors with one another, the values concerning the interfacial phenomena were high, but those concerning washing conditions were low, both with polyester and cotton.
3. The experimental values closely agreed with the values calculated from the multiple regression equations.
