Abstract |
This study was conducted to investigate the relationship between clothing microclimate and clothing thermal insulation (Icl). The subjects were 6 males and Icl was calculated by Winslow and Herrington's equation, and clothing microclimate and clothing weight were measured. Mean temperature inside clothing (Tcl) that was calculated as arithmetic mean of 5-points (abdomen, arm, thigh, leg, foot) had positive relationship with Icl (p<.01). The simple regression equation between Tcl and Icl is Y=0.160X-3.104 (Y: Icl, clo, X: Tcl, oC) (r=0.57, R2=0.325) and the multiple regression equation is Y=0.094X1+0.035X2-1.402 (Y: Icl, clo, X1: Tcl, oC, X2: Difference between the innermost surface temperature and the outer surface temperature of the clothing at the chest, oC) (r=0.66, R2=0.435) (p<.01). The abdomen area is suited to predict the temperature inside clothing for only one measurement because Tcl had highly positive relationship with abdomen area (r=0.883). Clothing weight had the highest relationship with difference between the innermost surface temperature and the outer surface temperature of the clothing at the chest (p<.01). In conclusion, through these results, mean temperature inside clothing could be regarded as an index of clothing thermal insulation (Icl). |
