８７号、同６０−８３１２０号）。On the other hand, with the advent of polymer absorbent sheets, many applications have been developed, mainly for preventing dew condensation or drip-proofing (for example, Utility Model Application No. 60-119
No. 87, No. 60-83120).

マー目付かｌｏｇ／ｍ’より少ない時絶対吸湿量が少な
いため効果かない。In the present invention, when the polymer basis weight exceeds 500 g/m', the polymer becomes plate-like and does not absorb moisture in the center. On the other hand, when the polymer basis weight is less than log/m', the absolute amount of moisture absorption is small, so there is no effect.
また、シート厚みか３１を越えると施工及び美的に問題
かてる。逆に、シート厚みか０，５■未層になると板状
になり吸湿性に問題かてる。Moreover, if the sheet thickness exceeds 31 mm, problems arise in terms of construction and aesthetics. On the other hand, if the sheet thickness is less than 0.5 mm, it becomes plate-like and causes problems in hygroscopicity.
本発明に用いられる高分子吸収シートは、上記■の構成
のものか好ましく、具体的には、繊維状シート基材から
成る。The polymer absorbent sheet used in the present invention preferably has the structure (2) above, and specifically, is made of a fibrous sheet base material.

ワーク構造のものも含まれている。In the above, the fibrous sheet base material is a support for the superabsorbent polymer described later, and is a sheet base material with a three-dimensional network structure made of fibers or materials that can be substituted for fibers. Specific examples include sheet substrates made of natural fibers, synthetic fibers, or mixtures thereof, sheet substrates made of thin metal wires, open-cell foamed plastic sheet substrates, and the like. Particularly when using a sheet base material made of natural fibers or synthetic fibers, it is advantageous in terms of cost to select a fibrous web containing a nonwoven fabric as the base material. The fibrous sheet base material is made by mixing pulverized pulp and super absorbent polymer particles (described below) and shaping the mixture into a sheet, which has a three-dimensional network structure with relatively high density in terms of numbers. It also includes things.

いることがてきる。Regarding the above-mentioned super-absorbent polymer, powders, granules, etc. of various super-absorbent polymers having water absorption and hygroscopic properties are covered with the above-mentioned fibrous sheet base material, and if necessary, this is then pressurized. The polymer can be used in a more strongly fixed manner to the base material.

ることが好ましい。Alternatively, a method in which a monomer of a superabsorbent polymer is polymerized in the fibrous sheet base material and the polymer is intermittently fixed to the sheet base material is used, in which the polymer is further firmly fixed. It is advantageous to go up. Such technology is disclosed in Japanese Patent Application Laid-Open Nos. 59-135149 and 2015-2215.
No. 75, US Pat. No. 4,500,315, and the like. In the present invention, for example, an aqueous monomer solution is applied to the am web using roller coach ink, spray coach ink, etc., and then polymerized and cured by heating, electron beam irradiation, etc. By doing so, the superabsorbent polymer is firmly fixed to the fibers intermittently and so as to wrap around the fibers, and does not easily fall off from the fiber web. The superabsorbent polymer is preferably used in a proportion corresponding to 100 to 1500% of the weight of the fibrous web in a dry state.

湿度コントロール作用かほとんどみられない。Examples of the polymer absorbent sheet include a polymer absorbent sheet made by adhering a super absorbent resin to aggregate as described in JP-A-1-198346, and a graft copolymer M!! as described in JP-A-52-276 (185). There are known polymer absorbent sheets made of fiber sheets, polymer absorbent sheets made of flexible sheets described in No. 63-105044 and a super absorbent resin fixed to them; Compared to molecular absorption sheets,
There is almost no humidity control effect.
