フィルタのフィルタエレメントに用いられる濾紙、特に
クレープ加工される濾紙の製造方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a method for producing a filter paper mainly used for a filter element of an air filter for an internal combustion engine, especially a filter paper to be creped.

は、次のような工程が考えられる。A crepe paper such as a decorative paper is known as a paper having wrinkles formed on its surface, but it cannot be simply used as the filter paper. That is, as described above, it is necessary to impregnate a resin to strengthen the paper strength so that it can be used for a filter element. When a general method for producing a filter paper including a resin impregnation step is applied to obtain a creped filter paper, the following steps can be considered.

クレープ加工は、周知のように、ロールの上でドクター
を用いて、しわを濾紙に形成させるものである。First, a suspension-like filter paper raw material stock containing predetermined fibers is prepared. At this time, an acrylic amide resin or the like is internally added and fixed to the fiber. Then, paper is made and a filter paper is formed from the stock. Further, the filter paper is subjected to creping and wrinkles are formed on the surface of the filter paper.
Finally, a dried and creped filter paper is obtained.
As is well known, creping is a technique in which a wrinkle is formed on a filter paper by using a doctor on a roll.

ィルタエレメント用の濾紙として、使用に耐え得ない。
すなわち、繊維に内添樹脂を定着させる工程において、

なり、この程度では十分な濾紙の強度が得られないので
ある。The creped filter paper obtained by the above manufacturing method has insufficient paper strength and cannot be used as a filter paper for a filter element.
That is, in the step of fixing the internally added resin to the fiber,
There is a limit to the fixing amount, and it is difficult to provide sufficient paper strength. In addition, the higher the amount of resin added internally, the more the amount of adhesion will increase, but on the other hand, a large amount of resin will be contained in the recovered liquid (white water), resulting in waste of resin and waste liquid treatment. Cause the problem of. Therefore, the fixing amount (adhesion amount) of the resin component is limited to about 10%, and sufficient strength of the filter paper cannot be obtained with this amount.

The filter paper raw material (paper material) is in the form of a suspension composed mainly of natural fibers such as linter and pulp. Second,
This paper material is supplied to a well-known roller (not shown), a suction box, and a paper making net of a paper making net made of a paper making net,
Make paper. Then, creping is performed. In the crepe process, the filter paper is wrinkled on a roll using a doctor as in the conventional case. After drying, resin processing is performed. The resin processing is performed by transferring a phenol resin to a filter paper by a kiss coater method using a container solution containing a phenol resin solution dissolved in a solvent. Finally, the resin is dried and cured to form a creped filter paper.
