られない欠点を有する。(Problems to be Solved by the Invention) In the former air filter paper described above, since the blending amount of cellulose is as high as 80%, it is weak against ultraviolet rays and γ rays and causes deterioration in strength. In the case of the latter air filter paper, since the fiber diameter of the synthetic fiber monofilament is large,
In order to collect more than 99.99% of DOP particles of 0.3μ, it is necessary to use paper with a high basis weight, but on the other hand, the pressure loss becomes extremely high, and after all it has the drawback that good air filter performance cannot be obtained. .

これにより構成することが特徴である。これによつて、
従来のセルロースの配合量が80％の紙に比して著しく
耐酸化性、耐γ線性、耐熱性を増大することができる。Examining the relationship between the polyester monofilament, which is one of the compounding materials for the air filter paper of the present invention, and the paper collection efficiency and pressure loss, the fiber cross-sectional shape is close to a perfect circle and is 0.1 denier (3 μ). However, it was found that the pressure loss was kept extremely low when it was necessary to collect 99.99% or more of DOP particles having a collection efficiency of 0.3μ with a higher basis weight of paper. In this case, the compounding amount is 80
Must be in the range of ~ 60%. That is, the feature is that most of the paper is made of this. By this,
Oxidation resistance, γ-ray resistance, and heat resistance can be remarkably increased as compared with the conventional paper having 80% cellulose content.

却可能紙として不適である。According to the present invention, it is important to add 30 to 10% of natural cellulose as a compounding material. If the amount added exceeds 30%, the UV resistance and γ-ray resistance will deteriorate and the service life will tend to be shortened. If it is less than 10%, the collection efficiency will be 99.97.
% Or less. That is, in order to improve the collection efficiency in the air filter paper of the present invention mainly composed of the polyester monofilament, a blending ratio of 10% or more is required. In the case of blending these two materials, high collection efficiency cannot be obtained, and it is necessary to blend glass fiber in the range of 10 to 30%. The average fiber diameter of glass fiber is generally 0.1-0.2μ
Is. The reason for adding at least 10% of glass fiber is that if it is less than that, the collection efficiency can be increased without significantly increasing the density of the paper. Additions of more than 30% are not suitable for incineration paper.

Paper obtained by blending 0%, natural cellulose 30 to 10% and glass fiber 10 to 30%, adding acrylic resin to this, mixing by papermaking method, papermaking, for example, capture of 0.3μ DOP particles A product with a collection efficiency of 99.99% and an excellent air filter performance with a significantly low pressure loss of 15 mm Aq is obtained, and it is also obtained as an air filter paper with UV and γ ray resistance, which is easy to incinerate and has a low ash content. It was recognized that it could be incinerated as a thing.
