ある保温性が不十分である。Another feature of the present invention is that the fabric made of the above-mentioned interlaced yarns must have a cloe value of 0.3 clo/cm or more and a specific volume of 1 cJ/g or more. The claw value here is an index of heat retention expressed by the level of thermal resistance of clothing.
m/s, if a white standard male resting in a chair feels comfortable and can maintain an average skin temperature of 33°C, then the thermal insulation power of the clothing worn by the white standard male is 1
Clo is determined as clo, but since there are variations such as individual differences, 1 reasonable physical clo value is 1 clo = 0.18
It is defined as °C-m'·hr-Kcal-', and the larger the value, the greater the heat retention. In the fabric of the present invention, the double claw value is 0.3.
It must be more than clo/cm. If the tl-value is less than 0.3 clo/cm, heat retention, which is an effect of the present invention, is insufficient.
