Three soiled test cloths of cotton and 65/35% Dacron/cotton blends with and without durable press finish were subjected to twenty‐five repeated launderings in Launder‐Ometer to determine the effect of fabric type, wash temperature, and laundering interval on the soil removal and soil redeposition performance. The reflectance of the test fabrics as measured by a Hunter Lab D‐40 reflectometer and the amount of soil removed and redeposited was computed in reflectance unit (RU) expressing the difference in reflectance of the test samples before and after washing. Soil removal and redeposition performances were significantly influenced by fabric type, detergent type, and laundering interval. Duncan's multiple range test indicated that Dacron/cotton blends with and without durable press finish retained and redeposited significantly less soil than cotton. Powder detergents cleaned test fabrics better than liquid detergents. Highly significant correlations between soil removal and redeposition RU and whiteness measurements were found. Therefore, both computations serve as reliable methods to evaluate soil removal and redeposition performance.
