This research concerned survival and redeposition of the fungus, Trichophyton mentagrophytes, on military footwear fabrics (50% wool, 30% nylon, and 20% cotton) subjected to various laundry procedures with water temperatures of 100°, 120°, and 140°F. and detergent concentrations of 0.0 percent and 0.2 percent; and the effect of the two solutions on fiber and fabric. A sequential experimental design was used to analyze data on the duration of survival of Trichophyton mentagrophytes on knit footwear during laundering. Standard test procedures were employed in the inoculation, soiling, and recovery of the microorganism. Fiber and fabric damage was determined through microanalysis and by testing for fabric strength and elongation. Only wash water of 140°F. significantly decreased the survival and redeposition of the organism. The effect of soiling on the inoculated fabric was significant in the number of pits and corrosion in cotton and in the bursting strength of the fabric. Detergent concentration was not significant for all types of damage in the textile fibers or for loss of strength and elongation in fabric. The number of launderings before inoculation was significant in damage for fibers and in loss of bursting strength and elongation.
