Abstract

The purpose of this study was to examine the relationship between the weight of seasonal garments worn by Korean women in their daily lives and thermal insulation. We selected a total of 121 garments(13 kinds of Under garments, 51 Upper garments, 32 Lower garments, 15 Headgear, 10 Gloves Footgear) based on our previous survey using questionnaire and interview. Thermal insulation of single garment was measured with a thermal manikin. Also we measured garment weight, covering area, thickness, air permeability on the each garment(chamber air temperature: $21.5{\pm}0.5^{\circ}C$, humidity: $50{\pm}5%R.H.$ air speed: 0.15m/s). The results are as follow: The very strong positive correlation(r=0.905, p<.01) was recognized between the weight of single garment and thermal insulation. The regression equation of thermal insulation can be represented as follows: Thermal Insulation(clo)=$0.03+0.0004{\times}Garment$ Weight(g)($r^2$=0.820, SEE =0.059). There are significant differences in the thermal insulation and garment weight by season and garment type(p<.05). The each garment category's thermal insulation and garment weight has as follows: Under garment(0.06clo, 89g), Blouse Shirt T-shirt(0.13clo, 200g), Cardigan Sweater Vest(0.14clo, 287g), Coat Jacket Jumper(0.41clo, 890g), Skirt(0.16clo, 276g), Trousers(0.20clo, 438g), Headgear(0.03clo, 102g), Gloves Footgear(0.03clo, 33g).
