The interaction between fabric and soil in detersive systems was elucidated by applying principal component analysis to data obtained in laundering cotton, nylon, polyester, and wool fabrics soiled with liquid paraffin, squalene, olive oil, lanolin, and palmitic acid, respectively, with thirteen different detergents under various bath conditions.
This analysis gives a meaningful summary of the original data, and concludes that only four components are required to represent the detergency by the twenty soiled fabrics; and that fabric type is a dominant factor and the geometric relationship between fabric and soil is one of the most important factors governing detersive systems. The geometric factor is ascribed to “micro-occlusion” due to the entrapment of particles in the irregularities of the fiber surfaces.
The soiled fabrics are plotted in a two dimensional space as a fabric-soil field mapping
