- the surface temperature on the skin side surface 2 was measured by a thermographic method. This measurement was performed with a thermoview (type TG-6300). The temperature of the skin side surface 2 was measured for 20 minutes when air was supplied to the heating element 31 and heat generation was started.
- the heating element of the example or the comparative example is taken out with the sealing bag force, and immediately after the oxygen is started to be supplied to the heating element, the example or the comparative example is placed on the styrofoam plate. At this time, the heating elements of the example and the comparative example are placed so that the skin side surface faces the polystyrene foam.
- the initial measured mass (P1) by an electronic balance is read.
- time measurement is started with a stopwatch.
- the measurement weight (P2) of the electronic balance is read.
- the difference between P1 and P2 is the amount of water vapor generated in 0-5 minutes (g)
- the difference between P2 and P3 is the amount of water vapor generated in 5-10 minutes
- the difference between P3 and P4 is The amount of water vapor generated in 10 to 15 minutes
- the difference between P4 and P5 is the amount of water vapor generated in 15 to 20 minutes.
- the difference between P1 and P5 is the total amount of water vapor generated for 20 minutes.
- FIG. 8 shows the results when eight warming bodies of the example were prepared and the temperature of the skin side surface 2 was measured.
- the horizontal axis represents the time (seconds) from the start of supplying air to the heating element 31, and the vertical axis represents the temperature (° C) on the skin side surface 2.
- FIG. 9 is a temperature characteristic diagram in which six warming bodies of comparative examples were prepared and the temperature on the skin side surface was measured in the same manner as in the example.
- Table 1 shows the measurement results of the amount of water vapor (water) released to the skin side surface 2 with respect to the four examples and the three comparative examples.
- the heating body of the example has a longer duration of heat release from the skin side surface 2 than the heating body of the comparative example.
- the maximum duration of heat generation from when the temperature rises above 50 ° C to below 50 ° C varies between the maximum of 520 seconds and the minimum of 70 seconds between the example and the comparative example.
