Popis:	A variety of cotton articles—such as tea towels, hand towels, and sheets—and test cloths, both cambric and sheeting, have been washed in a ‘Hotpoint’ Empress washing machine in a heavy-duty detergent product containing radioactive sodium carboxy-methyl cellulose (SCMC). There was good agreement between the results of laboratory tests using small discs of fabric and results of the practical test. Even when the cotton fabrics had been pre-washed up to 25 times in a product containing SCMC, some SCMC was still adsorbed (up to 40 μg/g of fabric) in each wash. It is suggested that in each wash some SCMC desorbs from the fabric and is replaced by SCMC adsorbed from solution.
