Samples of brown 50% polyester/50% cotton momie cloth with a fluorocarbon finish were commercially laundered using a carbonate‐built detergent in soft (0 ppm) water. The appearance of the laundered samples was assessed by subjective pilling ratings and instrumental colour determinations; the performance properties examined were tear and tensile strength, abrasion resistance and ability to release oil. The results showed that pilling was at its maximum after 20 launderings. The depth of colour decreased with increased number of cycles and, in most cases, was not accompanied by change of hue Tear and tensile strength were not affected by the laundering process. The fluorocarbon finish on the unlaundered control increased the weight loss due to Accelerator abrasion, thus that due to repeated launderings was significantly less. The finish protected the fibres from flex abrasion, increasing the number of cycles required to rupture the fabric and only the sample laundered 60 times had significantly greater resistance. The ability to release oil decreased with increased number of launderings. Oil remaining in the fabric was located in the interstices between yarns.
