Evaluation of clo values for infant's clothing using an infant-sized sweating thermal manikin

In this study, clo values for 34 infant's garments and 10 infant's ensembles were measured using an infant-sized sweating thermal manikin. Clo values of 34 types of garments ranged from 0.017 to 0.341. Correlation coefficients and linear regression equations between clo values and garment weight (g) and between clo values and body surface area covered by garment (BSAC, %) were 0.69, y = 0.0007x - 0.0013, and 0.75, y = 0.0034x + 0.0335, respectively. It was found that clo values of infant's garments could be estimated precisely from the garment weight or body surface area covered. Clo values of outdoor ensembles and indoor ensembles were distributed from 0.03 to 0.78 and from 0.07 to 0.32, respectively. The regression equation obtained between clo value and ensemble weight was y = 0.0008x - 0.0291, r = 0.96, and between the clo value of ensembles and the summation of each garments' clo value was y = 1.1097x - 0.0183, r = 0.96. This means that the prediction of the clo values of an infant's ensemble can be estimated precisely from ensemble weight and also from summation of the garments insulation.
