As disclosed in Japanese Patent No. 110, a homogeneous mixture of bulb fibers, fibrillated short polyethylene fibers, and powdered activated carbon is formed into a sheet, and the sheet is heated to a temperature above the melting point of the fibrillated polyethylene fibers to form fibrillations. Activated carbon and valve fibers are fixed together by melting a portion of the fibers.

低下する。In this case, it is desirable to use activated carbon with as small a particle size as possible in order to improve the dispersibility of the activated carbon in the base sheet and increase its ability to adsorb vapor phase components in tobacco smoke. Because it needs to be affixed to the base sheet with a binder such as an adhesive or fused fibrillated polyethylene fibers, many pores on the activated carbon surface are covered and blocked by the binder, reducing its ability to adsorb vapor phase components. .

いる。On the other hand, in Japanese Patent Application Laid-open No. 46-6946, fibers as a filtration material are flock-coated by electrostatic processing on a non-porous band-shaped sheet, and the fibers are planted on the sheet coated with an adhesive. A cigarette filter body is shown in which a cylindrical cylindrical shape is formed by joining the belt-like sheets together as shown in FIG.

在使用されているものより低下することとなる。In this case, physical adsorption ability for particle phase components can be expected, but adsorption of vapor phase components is impossible, and since the strip sheet has no air permeability, physical adsorption ability is currently used depending on the fiber selection. This will result in a lower level than normal.

電強制帯電加工をするうえで望ましい。Activated carbon fiber is made by carbonizing organic fibers such as acrylic, phenol, rayon, and cellulose to give it vapor phase adsorption ability, and its fiber strength is extremely weak.
It is 2 denier and 0.5 to 2 fins long. It is desirable that the particle size of the granular vapor phase adsorbent such as activated carbon or zeolite be 60 mesh or less, preferably 80 mesh or less, for uniform electrostatic forced charging.

These adhesives are selected and used appropriately depending on the material of the porous sheet material and the type of adsorbent to be fixed. Among these, emulsion type adhesives are the most effective because they can be diluted freely with water, have low initial viscosity and stickiness, are easy to work with, and use a ground electrode for forced electrostatic charging. It's advantageous.

The screen printing method is preferable because the size, area, and shape of the part to which the fixing liquid is attached can be freely changed.
