ぼす恐れが有る。EXAMPLE A material for a total heat exchange element according to a first example of the present invention will be described below. The raw material for the total heat exchange element is a slurry consisting of 25% by weight of cellulose fiber, 5% by weight of organic flameproof fiber and 70% by weight of mineral filler with an ordinary paper machine and a Gurley air permeability of 600 seconds or more. The paper is made to have a thickness of 110 μm or less. As cellulose fiber,
Wood pulp, bast fiber, etc. are used, and as the organic flameproof fiber, aramid fiber, flameproof vinylon fiber, etc. are used. Usually, glass fibers are often used as the flameproof fibers, but the fibers are rigid and it is difficult to take formation when forming a sheet, and the denseness is inferior. Further, when the obtained sheet is used as a material for a total heat exchange element, glass fibers may drop off, which may be harmful to the human body.

るいは複数混合使用する。On the other hand, the above-mentioned fried organic flameproof fiber has a relatively good formation during the formation of a sheet, does not impair the denseness of the sheet, and has a flameproof effect. The fiber diameter of the organic flameproof fiber is 1 to 8 μm.
m is preferable, and the cut length is preferably 3 to 5 mm. As a mineral filler, it is good if it has good moisture absorption and desorption characteristics,
As examples, there are magnesium silicate type, aluminum chloride type, aluminum hydroxide and the like, and these are used alone or in combination.

湿性能を向上させることができる。With the above-mentioned structure, the organic flameproof fiber has flame retardancy, has better compatibility with the cellulose fiber and the mineral filler than the glass fiber, and has improved dispersibility and uniformity among the respective materials. As a result, even if the thickness is reduced to 110 μm or less, it is possible to make paper with an air permeability of 600 seconds or more. By reducing the thickness, moisture permeability and thermal conductivity are further improved,
It is possible to improve the total heat exchange efficiency, that is, the moisture permeability while the ventilation efficiency is improved.

10 μm or less is desirable. The thickness of the material is a major factor in improving the total heat exchange efficiency, and it is desirable to consider the thickness of the material and the moisture permeability so that the same material is thinner.

必要な厚みとしては７０〜１１０μｍが望ましい。Therefore, it is desirable that the thickness is thin as long as the ventilation efficiency is not impaired. In this embodiment, the Gurley air permeability is intended to be 600 seconds or more for the purpose of improving the ventilation efficiency, and the thickness required for this purpose is preferably 70 to 110 μm.

が劣り好ましくない。The material for the total heat exchange element of this embodiment is composed of 18 to 48% by weight of cellulose fiber and 2 to 10 of organic flameproof fiber.
% By weight, 50-80% by weight of mineral filler.
This raw material composition was devised to improve the desired ventilation efficiency and total heat exchange efficiency.
Therefore, the target material cannot be obtained in a structure outside this range. For example, when the content of the mineral filler is 50% or less, it is difficult to obtain a highly moisture-permeable sheet, and the target total heat exchange efficiency is poor. If it is 80% or more, it is difficult to form a sheet as a raw material. Furthermore, regarding organic flameproof fiber,
If it is 2% or less, the flameproof effect is inferior, and if it is 10% or more, it is difficult to form a uniform sheet, and it is difficult to achieve the desired Gurley air permeability of 600 seconds due to lack of denseness. The blending of cellulose fibers is for the purpose of fixing the mineral filler, but if it is lower than this range, the fixing will be poor, and conversely, if it is too large, the flameproofing effect will be poor, which is not preferable.
