Fabric Bagging

Abstract

Aesthetic appearance is one of the most important criteria used by consumers in judging clothing wear performance. Bagging is a kind of three-dimensional residual deformation that deteriorates garment appearance during wear and causes dissatisfaction. To understand the psychophysical mechanisms of fabric bagging perception, a method of subjectively evaluating this behavior is developed by using a series of photographs taken from bagged fabric samples. Both ranking and rating scales are used as the psychological scales. The two scales are highly correlated with each other, but the rating scale provides more information than the ranking scales and can indicate perceived differences between fabrics. A linear relationship between subjective perceptions and measured residual bagging height shows that perception of fabric bagging follows Stevens' power law. Residual bagging height contributes up to 94% of the total variance in the perception of fabric bagging. The rest of the variation may be attributed to anistropic behavior during the bagging process.
