The effects of some modifications of cotton and polyester fibers on the soiling and soil release properties were studied. Carbon tetrachloride dispersions of carbon black containing oily components were chiefly used as soiling liquor. Among several chemical modifications of cotton fiber, carboxy-methylation and acetylation gave especially low degree of soiling and high soil release. Polyester fabrics treated with hot aqueous solution of sodium hydroxide and those dyeable with cationic dyes showed high soil release. It was recognized that the degree of soiling and soil release were fairly affected by the construction of fabrics. Fabrics of low weave density and knitting generally showed high degree of soiling. Polyester fabrics and yarns composed of the filaments having complicated cross-sectional shape such as octalobal showed soil release lower than that of circular cross-sectional filament. Dry soiling methods were also examined. Transfer soiling method using soiled polyurethane cubes gave uniform soiling.
