S Z0701 absorbs a large amount of moisture at high humidity and is defined as having a large absorption capacity. The moisture absorption rate at a relative humidity of 20% is 3.0% or more and the relative humidity is 50%.
The silica gel has a moisture absorption rate of 10.0% or more and a moisture absorption rate of 50.0% or more at a relative humidity of 90%. In the present invention, the more preferable range of the moisture absorption rate at a relative humidity of 90% is 60 to 120%.

It is preferably from about 1000 μm. Particle size is 10μ
If it is less than m, it leaks from the nonwoven fabric and is not suitable. When the particle size exceeds 1000 μm, the mat wrapped with the non-woven fabric has irregularities on the surface, which is uncomfortable when contacted by a human body, which is not suitable. A more preferable range of the particle size of silica gel is 40 to 600 μm.
【０００８】シリカゲル粒子の外形が球形である場合
は、流動性がよくて包装しやすく、マットと人体が接触
した場合の感触がよいので好ましい。The silica gel particles having a spherical outer shape are preferable because they have good fluidity, are easy to package, and have a good feel when the mat and the human body are in contact with each other.

の厚さのより好ましい範囲は、２〜５ｍｍである。The thickness of the moisture absorption layer is preferably 1 to 6 mm. If the thickness is less than 1 mm, the amount of moisture absorption per unit area of the mat will be insufficient, which is not suitable. When the thickness exceeds 6 mm, it is difficult to dry the mat in the sun and dehumidify it within the sunshine duration of one day, which is not suitable. The moisture absorption layer may have some variation in thickness, and the thickness of the moisture absorption layer here means an average thickness. A more preferable range of the thickness of the moisture absorption layer is 2 to 5 mm.

るので好ましくない。Regarding the air permeability of the non-woven fabric, the Frazier air permeability is preferably 1.0 × 10 −4 to 2.0 m 3 / m 2 · s. Frazier air permeability is 1.0 × 1
If it is less than 0 −4 m 3 / m 2 · s, the ventilation resistance of humidity becomes large, and the moisture absorption rate and the desorption rate of moisture due to sun drying become slow, which is not preferable. When the Frazier air permeability exceeds 2.0 m 3 / m 2 · s, the nonwoven fabric becomes coarse and the silica gel particles may leak, which is not preferable.

The powder generated from the silica gel particles inside due to impact may leak to the outside. In order to prevent powder leakage more reliably, it is preferable to use a nonwoven fabric laminated with a porous film. In the case of a non-woven fabric laminated with a porous film, the Frazier air permeability is 1.0 × 10 -4 ~
It is preferably 1.0 × 10 -2 m 3 / m 2 · s.
To express this level of air permeability, JIS P8117
The air permeability of the Gurley method based on is preferred. The air permeability of the Gurley-type method of nonwoven fabric laminated with a porous film is
15 to 1500 s / 100 ml is preferable. More preferably, it is 25 to 500 s / 100 ml.
