Abstract


Three combinations of cloths were evaluated for the protective effects of different kinds of clothings in cold environments. Table 1 shows the components of the three models of clothings. A prototype was made by putting a sheet of vinyl at the middle layer of raw cotton in a fabric-quilt cloths.

A glove mannequin was covered by each of these cloths. The globes contained 1,000 cc of hot water about 40°C. Tele-thermisters were fixed in order to check the temperature of-´cloths space and water temperature for evaluation of calorie-loss and climate of clothings.

Results are summarized as follows:

1) Without wind, there is no significant difference of air temperatures between ski-parka and quiltwear clothing.

2) The prototype with vinyl sheet best protects against wind, the next is the ski-parka. Quilt-wear protects the least.

3) It is well-known that a working-clothing needs not have any separate liners nor outers.

4) For innermost layer of a clothing preventing cold, a cotton-fabrics is recommended and a water proof cloths for outer layer.

5) Heat-loss was calculated from the cooling degrees of water. Calorie-loss was 910ca1/m2/hr. when bared, but with the prototype of vinyl sheets the calorie-loss was 350ca1/m2/hr. (38.5% of bared). Quilt-wear and ski-parka were 380(41.8%) and 440 cal/m2/hr.(48.4%) respectively.
