Hs. Yoo et al., Effects of heat and moisture transport in fabrics and garments determined with a vertical plate sweating skin model, TEXT RES J, 70(6), 2000, pp. 542-549
A vertical sweating skin model is developed and changes in vapor pressure w
ithin a clothing system are measured to investigate the effects of fiber ty
pe, air layer thickness, and garment openings on the microclimate. Cotton b
roadcloth, polyester broadcloth and cotton canvas are considered. Openings
of a garment, such as neck, armhole and waist, are simulated, and the total
openness is controlled at 0, 10, 20, 40, and 60%. To evaluate changes in t
he microclimate of the clothing system, a buffering index K-d and the effic
iency of openness are determined. Results show that the buffering index of
polyester is higher than that of cotton. As the thickness of the air layer
increases, the buffering index increases but an unnecessarily large air gap
does not increase the buffering capacity efficiently. As the openness incr
eases, the effect of fabrics on the microclimate decreases gradually, losin
g its effect at 60% and approached the value of nude skin.
