- 40% by weight of a fineness of 1.7 dtex A thermoplastic non-woven fabric obtained by dispersing PE and PP composite synthetic fiber with a fiber length of 7 mm in water in a papermaking tank and making two layers with a circular yankee drum was used.
- the weight per unit area of the non-woven fabric was 30gZm 2.
- non-moisture permeable heat insulating layer 33 a foamed polyethylene sheet having a foaming ratio of 30 times, a thickness of 1 mm, and having a through hole formed was used.
- the heating base of the heating element 31 includes iron powder, activated carbon, vermiculite, and wood powder, and is not subjected to pressure treatment for aggregating the iron powder.
- the total mass is 42 g, basis weight. 2800gZm 2 was used.
- the sheets are stacked with the heating element 31 sandwiched, and the sheets are heat-fused by embossing.
- the thin sheet portion 15 was formed by wearing, and the humidified body of the example was obtained.
- Example B a polyethylene resin film stretched with an inorganic filler, formed with water vapor permeation holes 41, with a temperature of 40 ° based on JIS-Z0208.
- the same water vapor permeable holes 41 as those of the skin side surface sheet of Example A were formed on the skin side surface sheet of C, with a moisture permeability of 000 gZm 2 '24h measured at a relative humidity of 90%.
- a structure having the same structure as that of Example A except that only the skin side surface sheet 4 was replaced was produced.
- a moisturizing body as a comparative example was obtained by using, as a skin-side surface sheet, a film having the same water-repellent film as in Example A but without forming water vapor permeation holes 41.
- a structure having the same structure as that of Example A except that only the skin side surface sheet 4 was replaced was produced.
- a moisturizing body as a comparative example was obtained by using, as a skin-side surface sheet, a film having the same water-repellent film as in Example B but having no water vapor permeation holes 41 formed therein.
- the humidifying body of the example or the comparative example is taken out with the sealing bag force, and the humidifying body of the example or the comparative example is placed on the foamed polystyrene plate immediately after oxygen is supplied to the heating element. At this time, the humidified body of the example or the comparative example has its skin side surface directed to the expanded polystyrene.
- the initial measured mass (P1) by the electronic balance is read.
- start time measurement with the stopwatch read the measured mass (P2) of the electronic balance after 5 minutes, and measure the measured mass (P3) after 10 minutes, and the measured mass (P3) after 15 minutes.
- the difference between P1 and P2 divided by the area of the skin-side surface sheet 4 covering the heating element 31 (the area of the humidifying part) is the amount of water vapor generated per unit area after 0 to 5 minutes ( gZcm 2 ).
- the difference between P2 and P3, 5 ⁇ the amount of water vapor generated per unit area when the LO minutes elapse (g / cm 2 )
- the amount of water vapor generated (g / cm 2 ) is obtained.
- the differential force between P1 and P5 the total amount of water vapor (g / cm 2 ) per unit area in 20 minutes is obtained.
- Example A the amount of water vapor generated per unit surface when 0 to 5 minutes elapses. Power 0.009 gZcm 2 or more, the amount of water vapor generated per unit area after 5 to 10 minutes elapses but, 0. 007gZcm 2 above, the steam generation amount force per unit area at the elapsed 10-15 minutes 0. 008 gZcm 2 or more, the steam generation amount per unit area at elapsed 15-20 minutes, 0. 003g / cm It was 2 or more. The total amount of water vapor generated per unit area over 20 minutes was 0.03 g / cm 2 or more.
- the amount of water vapor generated per unit area in 5 minutes is 0.003 gZcm 2 or more, and the amount of water vapor generated per unit area in 5 minutes is from 0 to 15 minutes. 0. 007gZcm 2 or more.
- Example A Prepare four humidifiers for each of Example A, Example B, Comparative Example A, and Comparative Example B, remove them from the sealed bag, and when 10 minutes have passed since oxygen began to be supplied to the heating element, respectively.
- the water vapor generation state of the skin side surface force of these samples was observed by touching the skin side surface. Those with sufficient water vapor were evaluated with “ ⁇ ”, and those with poor water vapor generation were evaluated with “ ⁇ ”.
- each humidifying body is observed, the heating element is accommodated, and the humidifying portion swells.
- the bulge was evaluated as “existing” and the non-bulged one was evaluated as “absent”. The results are shown in Table 2 below.
