Odor Retention on Apparel Fabrics: Development of Test Methods for Sensory Detection

Abstract

A method for collecting axillary odor on nine knit fabrics was developed and odor intensity determined using a panel of assessors. Two methods, one involving paired-comparisons in the quad analysis method and the other a line scale, were investigated to determine if differences in intensity of odor retained on the fabrics varying by fiber and fabric structure could be detected. Both methods allowed detection of differences. However, the line scale method was more time-efficient and enabled a greater number of assessors on the panel, an advantage for reducing the effect of individual differences in sensitivity to axillary odorants. Recommendations for a collection method, handling and assessment method are raised.
