AATCC Test Method 61-75 "Colorfastness to Washing, Domestic and Laundering, Commercial Accelerated," and International Standard Method C06 were modified to establish the laundry procedure to simulate one home laundering cycle. An Atlas Launder-Ometer equipped with stainless steel canisters was used. Teflon liners were used In the lids to prevent retention of pesticides by the rubber gaskets. Abrasive action was provided by the placement of 25 steel balls In each canister.
