たりして行っている。2. Description of the Related Art Conventionally, as a method for producing a filtering material for deodorization or the like using activated carbon, a bag is formed using a gas permeable sheet such as paper or nonwoven fabric, and activated carbon is charged into the bag. A method of sealing the mouth of a bag is used. However, this method has a drawback that a process for preparing a bag, a process for charging activated carbon into the bag, and a process for sealing the mouth of the bag exist, and the manufacturing process is complicated and the production efficiency is poor. For this reason, a method has been proposed in which activated carbon is evenly sprayed on the air-permeable first sheet, and the air-permeable second sheet is laminated thereon to produce a filter material. In addition, in order to join the first sheet and the second sheet, an adhesive is applied to one of the sheets, or the adhesive is sprayed together with the activated carbon.

というものである。However, since the activated carbon is uniformly present between the sheets in the filter material obtained by this method, the activated carbon sometimes spills from the cut edge when it is cut into a predetermined size. The filtering material is generally sandwiched between frames of a predetermined size and used as a framed filter. Therefore,
When creating a filter, the filter medium is cut to a predetermined size.In the case of the filter medium described above, activated carbon spills from the cut edge and becomes dust, and the working environment at the manufacturing site of the filter body is poor. Had the disadvantage of becoming Moreover, since the activated carbon and the adhesive coexist between the sheets in the above-mentioned filter material, there is a danger that the surface of the activated carbon is covered with the adhesive, and there is a disadvantage that the deodorizing performance of the activated carbon is impaired. Then, this invention aims at providing the manufacturing method of the filter medium which prevented activated carbon from spilling from a cutting edge even if it cuts.

出入する濾過体を得ることも考えられる。That is, the present invention is to form an activated carbon existing area having a predetermined area arranged at a predetermined interval in the longitudinal direction and at a predetermined interval in the width direction on the flat air-permeable first sheet, and then to form a flat air-permeable area thereon. Laminating the second sheet to form a laminate, and then bonding the heat-adhesive fibers contained in the first sheet and the second sheet in the activated carbon-free area formed between the activated carbon-present areas The present invention relates to a method for producing a filtering material, which comprises developing the properties and directly joining the first sheet and the second sheet to integrate the laminate. Hereinafter, a method for producing a filter medium according to the present invention will be described with reference to the drawings, particularly FIG. First, while transporting the flat air-permeable first sheet (1) along the guide roll (9) (to the right in the drawing), several activated carbon sprayers (2) installed at regular intervals. Activated carbon (5) is sprayed on the first sheet (1). The spray opening of the activated carbon sprayer (2) is intermittently opened and closed, and the activated carbon (5) is intermittently sprayed on the first sheet (1). Therefore, as shown in FIG. 1, the activated carbon existing areas (3) having a substantially long side are arranged at regular intervals in the longitudinal direction and at regular intervals in the width direction. An area other than the activated carbon existing area (3) becomes an activated carbon non-existent area (4). In addition, paper, a nonwoven fabric, a knitted fabric, or the like is used as the breathable first sheet (1). In addition, since the properties of the activated carbon are powdery or granular, a general powder non-sprayer may be used as the activated carbon sprayer (2). As a method for forming the activated carbon existing area (3) in the present invention, in addition to the above, it can be formed by the following method. That is, the activated carbon (5) is evenly sprayed on the entirety of the first sheet (1), and thereafter the activated carbon (5) is removed from an area corresponding to the activated carbon non-existent area (4) by an activated carbon suction device. As shown in the figure, an activated carbon existing area (3) may be formed. Thereafter, a flat breathable second sheet (6) is laminated thereon to create a laminate (7). Then, the laminate (7) is pressure-bonded by the pressure roll (8), and the first sheet (1) and the second sheet (6) are directly joined in the activated carbon absence area (4) to form the laminate (7). ). In addition, paper, a nonwoven fabric, a knitted fabric, or the like is used as the breathable second sheet (6). As a method of directly joining the first sheet (1) and the second sheet (6) in the activated carbon absence area (4), the following method can be used. That is, as the first sheet (1) and the second sheet (6), paper, knitted fabric or non-woven fabric containing a heat-adhesive fiber is used, and a heating roll is used as the pressure roll (8). 8) Heat is applied to the first sheet (1) and the second sheet (6) to cause the heat-adhesive fiber to exhibit adhesiveness, and the first sheet (1) and the second sheet (1) are activated in the activated carbon-free area (4). This is a method of directly joining the two sheets (6). When the heat-adhesive fiber is used as a component of the first sheet (1) or the second sheet (6), a composite fiber having polypropylene as a core component and polyethylene as a sheath component, nylon 66 as a core component and nylon 6 as a core component. A conventionally known thermoplastic fiber whose surface is softened and melted at a relatively low temperature, such as a conjugate fiber, an undrawn polyester fiber, or an undrawn polypropylene fiber as a sheath component, can be used. As the pressure roll (8), a smooth roll is generally used, but a portion corresponding to the activated carbon non-existing area (4) becomes a convex portion, and a portion corresponding to the activated carbon existing area (2) becomes a concave portion. Alternatively, an embossed roll may be used. When this embossing roll is used, the first sheet (1) and the second sheet (6) come into good contact with each other at the projections of the embossing roll even if the amount of powder in the activated carbon existing area (3) is increased. There is an advantage that direct joining between the first sheet (1) and the second sheet (6) is facilitated. The filter material obtained as described above has a sealing portion (1) in which the first sheet (1) and the second sheet (6) are directly joined.
The filter is cut at 0) and used as it is or as it is sandwiched between frames or the like to be used as a framed filter. The filter body may perform deodorization or decolorization by positively flowing gas or liquid into or out of the filter, or perform deodorization or decolorization without positively flowing gas or liquid into or out of the filter. You may. And this filter is air purifier, air conditioner, air conditioner,
It is used by being incorporated in refrigerator deodorizers, sanitary napkins, disposable diapers and the like. In the present invention, both the first sheet (1) and the second sheet (6) have air permeability. Although it is outside the scope of the present invention, a gas or liquid is used only from one side by using a gas-permeable sheet for one of the first sheet (1) or the second sheet (6) and a gas-impermeable sheet for the other. It is also conceivable to obtain a filter which flows in and out.

場の労働環境が良好になるという効果を奏する。As described above, the filter medium obtained by the method according to the present invention has a sealed structure in which the first sheet (1) and the second sheet (6) are directly joined, as shown in FIGS. A portion (10) and a sealing portion (11) in which the activated carbon (5) is sealed, and the sealing portions (11) are arranged at regular intervals in the longitudinal direction and at regular intervals in the width direction. Then, this filter medium is cut at the sealing portion (10) at the time of producing a filter body with a frame or the like. Therefore, the activated carbon does not spill from the cutting edge, and there is no generation of dust, so that the working environment at the manufacturing site of the filter body is improved.
