A procedure for measuring the redeposition of natural soils onto clean fabrics was developed. Laundry bundles of paired articles from typical households were divided and washed under controlled conditions in a home style washing machine. Large swatches of unsoiled fabrics were included in the laundry load. After each laundering small swatches were cut out for reflectance measurements. The large swatches were rated by panelists after every 5 cycles. Twenty cycles were run. Results demonstrated that the test discriminates between similar products. The effect seen was quite similar to the soil build‐up which occurs in the Laundry Bundle Test ASTM‐D‐2960. However, the bundle test requires much time to complete while the test described here can be run at the rate of several cycles per day. Also, it is not necessary to purchase new clothing for each test.
