In Vivo Cutaneous and Perceived Comfort Response to Fabric

Abstract

We studied stratum corneum water content, water evaporation from the skin surface, capillary blood flow, and skin temperature under three different garments worn by ten female subjects exercising and resting in a hot, humid environment (29.4°C, 75% RH). Single jersey knit fabrics made from 100% 1.5 denier polyester, 100% 3.5 denier polyester, or 100% cotton were made into long sleeve T-shirts and pants. Measures of stratum corneum water content using a microwave probe, evaporative water loss using an Evaporimeter, capillary blood flow using a laser Doppler velocimetry instrument, as well as skin temperature, were assessed on the upper back at four times during the wear protocol. An analysis of variance showed that there were no statistically significant differences in the noninvasive skin measurements under the three fabrics. Statistically significant differences in the skin measurements did occur as the kind of activity differed during the wear protocol. Results are discussed in terms of the fabric thermal and mechanical data presented in Parts I and II of this series.

Review of methods used for quantifying excess water in over-hydrated skin using evaporimetry

“…1). In another study of the impact of initially dry fabrics on skin worn under hot humid conditions, Hatch (1990) (22) addressed this issue by blotting sweat from the skin surface before logging WVFD.…”

Evaluation of Scalp Hydration and pH Values in Hijab-Wearing and Non-Hijab-Wearing Women

“…Hatch et al 38 reported that the upper back skin hydration values among hijab coated with cotton, polyester 1.5 denier, and polyester 3.5 denier fibers were not significantly different in the dry state. In the wet state, the skin hydration values were significantly different, with cotton group having the lowest value and polyester 3.5 denier fibers having the highest.…”

“…In the wet state, the skin hydration values were significantly different, with cotton group having the lowest value and polyester 3.5 denier fibers having the highest. 38 The effects of hijab material, the number of garment layers, and the use of inner hijab toward the results of this study were adjusted by ensuring that the subjects’ scalp were in dry state for three hours prior to the biophysical examination.…”

Performance Evaluation of Newly Designed Disposable Surgical Gowns

“…Thermophysiological clothing comfort depends on the heat and moisture transport properties of the garment that provide the body's heat balance [8][9]. In the literature, parameters affecting thermophysiological comfort are given as personal features, environmental features and clothing features [10][11][12][13][14][15][16][17]. Major clothing properties affecting thermal comfort include thermal conductivity, water vapor permeability, air permeability and water impermeability [2].…”
