使用に耐えることが充分できない。[0004] A sheet comprising a cushion body and two or more layers of constituent members including a side cover that covers the cushion body. In order to prevent the accumulation of moisture on the upper surface in contact with a person, the sheet is formed in the thickness direction of the side members. Japanese Unexamined Patent Publication (Kokai) No. 3-213546 discloses an apparatus in which a difference in density is provided so that moisture transfers to the back surface of the side ground. However, with this alone, the migrated water simply accumulates on the backside of the side ground and flows backward during use,
Not enough to withstand use.

Japanese Patent Application Laid-Open No. 5-5260 discloses a device using a special fiber having a water absorption of 100% or more. However, it is not a fundamental solution, but the time during which water is accumulated is long, and the possibility of backflow can be reduced, but a humid state cannot be maintained for a long time.

に至らない。Further, Japanese Patent Application Laid-Open No. Hei 3-23452 discloses a structure in which porous fibers are used on the side surface to absorb the water generated. However, when moisture is absorbed by the side ground surface, the moisture returns in reverse during use, so that a wet state occurs and comfort cannot be obtained.

云う問題まで新たに発生する。[0007] In addition, a water-absorbing material installed on the surface opposite to the upper surface by using a hydrophobic fiber material on the upper surface with the constituent member not limited to the side ground so that the feeling of wetting caused by stuffiness is reduced. Japanese Patent Application Laid-Open No. 9-31823 discloses a structure in which fibers are partially exposed on the upper surface. However, in these measures, a predetermined effect can be obtained in "feeling of stuffiness" for about 30 minutes to about 60 minutes, which is the stage when the sheet has begun to be used, but the effect decreases as time passes.
If it exceeds 60 minutes, the "feeling of stuffiness" increases remarkably,
Since the constituent members contain a large amount of water such as sweat, they become hotbeds on which various germs and the like can propagate, and a new problem that the sanitary aspect is remarkably deteriorated occurs.

A member in which air permeability is imparted to a member is disclosed in Japanese Patent Publication No. 3-70519. However, since there is no air movement, the effect is not obtained when the amount of sweating is large from the beginning such as after exercise.

Japanese Patent Application Laid-Open No. 3-29 discloses an air duct installed in a cushion body to suppress the generation of moisture such as perspiration.
No. 7,414, and Japanese Patent Application Laid-Open No. 5-111419. However, there is a problem in that a complicated air duct needs to be provided in the cushion body, and the basic mechanical characteristics are impaired.

Melting point (Tm) and endothermic peaks other than melting point The temperature of the melting peak (endothermic peak) was determined from the endothermic curve using a TA50, DSC50 type differential thermal analyzer manufactured by Shimadzu Corporation. The heating rate was 20 ° C./min. 2. Elongation recovery rate at 70 ° C. A film having a thickness of about 300 μm (Tm +

Using a Tensilon UTM5 model manufactured by Orientec, stretched to a strain of 10% at a strain rate of 100% in a heating oven in an atmosphere of 70 ° C., and then held for 24 hrs as it is. Then, return the strain to 0%,
The value obtained by subtracting the strain at which the stress appears when the film was stretched again from 10% was divided by the strain 10%. (N =
3) 3. Room temperature elongation recovery rate About 300 μm thick film (Tm +
After heating to 10 ° C and pressing for about 1 minute with a press machine, water cooling)
As a sample, using Tensilon UTM5 manufactured by Orientec, elongating to 300% strain at an elongating strain rate of 100%, returning to 0% strain, leaving it for 2 minutes, and then elongating the strain when the strain is elongated again. The strain was obtained by dividing the strain subtracted from 300% by the strain 300%.
(N = 3) 4. Thickness, basis weight, and bulk density The thickness at four corners of a sample cut to 15 cm was averaged to obtain a thickness. The weight was measured, and the weight was divided by the area to obtain the basis weight, and the weight was divided by the volume to obtain the bulk density.
(N = 5) 5. A sample punched to an air permeability of φ10 cm is sealed in a metal cylinder with an inner diameter of φ10 cm with a height sufficient to cover the thickness of the sample with a compressive strain of 5% applied, and a packing with a thickness corresponding to the strain. After sealing to prevent lateral leakage, the air flow rate was measured using an air flow rate measuring instrument manufactured by Techno World Co., Ltd. (Cosmo Instruments Design), and this was defined as the air permeability. The differential pressure was set at 124 Pa. 6. Heat resistance (70 ° C compression residual strain) □ Measure the thickness of the sample cut to 15 cm (average of the thickness of four corners), and apply 50% compression strain to the thickness. After being kept in a heating oven at 70 ° C. for 22 hours, the material was left standing at room temperature and cooled to remove strain, and the difference between the thickness after 24 hours and the thickness before treatment was divided by the thickness before treatment. (N = 3) 7. Water absorption (water absorption rate) Measured according to JIS L1018 A method (drop method). 8. Δq max Heat source plate set temperature 35 ° C, sample mount base set temperature 20 ° C
And humidity humidity a maximum heat transfer rate of the sample tone q max in the maximum heat transfer rate of the wet sample and wet q ma x,
The difference was defined as Δq max . Humidity control sample size 65
A sample of mm was conditioned at 20 ° C. and 65% RH and attached to a sample mounting table with the surface side of the side ground facing the heat source plate. In addition, 0.9 cm 3 of water was evenly applied to the wet sample using a syringe on the surface side of the side of the humidity control sample.
What was left still for 20 sec was used. 9. Moisture permeability Measured according to JIS L1099 A method (calcium chloride method). Ten. Comfort Set the prepared sheet sample on the sheet frame and
A subject is seated in a room at 8 ° C. and 75% RH (Subject 5).
