DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an elevational view schematically showing a state in which a curtain interlining according to the present invention is applied to an upper part and a lower part of a curtain. FIG. 2 is a partial sectional view of FIG. As shown in FIG. 1 and FIG.
0 is cut into a size corresponding to the size of the window of the house, and the folded portions 12A and 12A are provided at the upper end and the lower end, respectively.
B. The upper folded portion 12A is attached to a curtain rail runner by a curtain hook (not shown).

The upper folded portion 12A has a thick interlining 14
A, a thin interlining 14B in the lower folded portion 12B,
It is held in each of those bags. The reason why the thick interlining 14A is used for the upper folded portion 12A is to maintain the shape of the upper portion of the curtain correctly, while the thin interlining 14B is used for the lower folded portion 12B because the natural fold at the lower portion of the curtain is used. It is to get out. These interlinings 14A and 14B can be made of a sheet made of non-woven fabric or paper, and the sheet itself has a deodorizing and harmful substance removing effect in advance.

FIG. 3 is a diagram showing a manufacturing process of such a sheet, and is a process diagram showing a first embodiment of a method for manufacturing a sheet for deodorizing and removing harmful substances according to the present invention. FIG. 3 shows an apparatus and a process for producing a roll of a desired sheet by irradiating a sheet impregnated with a deodorizing agent and a harmful substance removing agent with gamma rays for graft polymerization. The sheet 20 unwound from the sheet (nonwoven fabric or paper) roll 20A before being impregnated with the deodorant and harmful substance remover is conveyed by rollers 22 to 28 as indicated by an arrow M1 in the drawing, and finally wound. The roll 20B is formed.

The roll 20B is rotated by a drive mechanism not shown, and a part of the rollers 22 to 28 is also rotated by a drive mechanism not shown. The container 46 holds a liquid deodorant and harmful substance remover, and when the valve 48 is opened, the deodorant and harmful substance remover 50 is poured into the lower sponge member 42. Below the sponge member 42, the sheet 20
Another sponge member 40 is disposed so as to sandwich the sponge member, and these two sponge members 40 and 42 are opposed to each other at a predetermined pressure by a mechanism not shown.

The deodorant and harmful substance removing agent 50 dropped from the container 46 is contained in these sponge members 40 and 42, and when the sheet 20 is conveyed between them, the deodorant and harmful substance removal agent is removed. The sheet 50 is impregnated with the agent 50. The sheet 20 is conveyed in a zigzag manner by the plurality of rollers 30 to 38 in order to dry the sheet 20 wet by the hot air 54 from the heater 52. Before or after this drying step, the sheet 20 is irradiated with a gamma ray 58 generated by a gamma ray irradiation device 56. The illustrated embodiment shows a case where gamma rays are irradiated after the drying step. By this gamma ray irradiation, the deodorant and harmful substance remover 50 impregnated earlier is graft-polymerized. In addition,
After the drying is completed, the transport speed and the winding speed are controlled so that the roll 20B is wound up.

As the deodorant and harmful substance remover 50, a deodorant and harmful substance remover for graft polymerization is used. The deodorant and harmful substance removing agent for graft polymerization is obtained by introducing a functional group into a graft chain, and a cation exchange group or a sulfonic acid group and a carboxyl group can be used as the functional group. Deodorant using cation exchange group
No.-79593, specifically, a molded article composed of a substrate made of pulp and / or polyolefin has a cation exchange group. In order to produce such a cationic deodorant, a reactive monomer is graft-polymerized to a molded article. A deodorant using a sulfonic acid group and a carboxyl group is described in "Environmental Technology", 1993
Evaluation of the performance of pulp ball-based deodorizing materials ”published in the May issue (Vol.22 No.5), pp22-25, using gamma-ray simultaneous irradiation graft polymerization It is one in which a sulfonic acid group and a carboxyl group are introduced into a cellulosic pulp ball.

These graft polymerization deodorants and harmful substance removing agents deodorize and detoxify odor-causing substances and harmful substances by chemical reaction with the odor-causing substances and harmful substances. The principle of deodorization is different from physically adsorbing the causative substance. Therefore, the graft deodorant and harmful substance remover does not react any more after the chemical reaction with the predetermined amount of malodorous substance, but when adsorbing a certain amount of the substance causing malodor such as the one using activated carbon However, it does not release the causative substance adsorbed by saturation. The amount of time required to cause a chemical reaction with a certain amount of the odor-causing substance is not constant because it depends on the quality and quantity of the odor-causing substance. For a regular house,
The chemical reaction effect lasts for about 3 to 6 months, but harmful formaldehyde, toluene, xylene, wood preservatives, plasticizers, termiticides, etc. can be almost completely removed in the first few days to weeks. is there.

In order to remove the odor of tobacco and other unpleasant odors other than these harmful substances, the sheets 14A and 14A impregnated with the above-mentioned deodorant and harmful substance remover are used.
B (see FIGS. 1 and 2) may be used together with an adsorption type deodorant containing activated carbon as a main component.

In the sheet manufacturing process shown in FIG.
Although the sheet 20 is formed in advance and imparts a deodorizing effect to the sheet 20, a deodorizing and harmful substance removing effect can be added at the stage of manufacturing the sheet as paper. FIG. 4 is a flowchart showing a second embodiment of the method for producing a deodorizing and harmful substance removing sheet according to the present invention.

In step S1, raw material pulp is charged.
At this time, in addition to pulp as a raw material for ordinary paper, a deodorant and harmful substance remover prepared by a graft polymerization method using pulp as a base material is added as a solid raw material. These two types of raw materials are stirred in step S2. After that, beating (Step S)
3), water addition (step S4), further beating (step S4)
5), paper making (step S6), and drying (step S7) are performed to produce paper.

In the flow of FIG. 4, a deodorizer and a harmful substance remover made by a graft polymerization method in the first raw material input stage (step S1) and using pulp as a base material are used as original raw materials. Although it is mixed, if the deodorant and harmful substance remover made by the graft polymerization method and using pulp as the base material is a finely cut fiber in advance, step S3 in the flow of FIG. And step S4.

That is, FIG. 5 shows a modification of the flow of FIG. 4. In step S1A, pulp as a first raw material, which is an original paper raw material, is charged, and after crushing (step S3), grafting is performed as a second raw material. A deodorant and harmful substance remover made by polymerization and using pulp as a substrate is charged (step S1B). After that, stirring (Step S
2), water addition (step S4), further beating (step S4)
5), paper making (step S6), and drying (step S7) are performed to produce paper in the same manner as in the flow of FIG.

The deodorizer and harmful substance remover made by the graft polymerization method using pulp as the base material is mixed at a fixed ratio with respect to the original raw material. If tens of grams are mixed, a practical deodorizing and harmful substance removing effect is produced. In particular, deodorizers and harmful substance removers made by graft polymerization, which use pulp as the base material, do not change their chemical action, that is, their deodorizing and harmful substance removing effects, even if they are finely cut. Thus, even if mixed into the raw material pulp, the effect is exhibited. The method of FIGS. 4 and 5 differs from the method of FIG. 3 in that paper is manufactured from the beginning, but when compared on a finished product basis, FIGS. 4 and 5 are cheaper.

The above-mentioned sheet of the present invention produced by the method of FIGS. 3 to 5 is not only attached to a curtain as shown in FIG. Various products such as sanitary shorts and accessories for sanitary shorts can be provided. This will be described below. First, by applying to furniture, such as sofas, beds, and chairs, which frequently come into contact with the human body, it is possible to effectively remove odors and the like that easily permeate there. Specifically, before covering the surface of the furniture, the subbing fabric for furniture made of the sheet according to the present invention is stretched, and then the fabric is stretched.

The clothing is realized as a white robe for medical personnel, work clothes or an apron for workers who deal with strong odors such as seafood, garbage, industrial waste, and decay. In addition, it can be realized as the sanitary short itself, or as an accessory of the sanitary short, that is, as a partial cover part, an address cloth, or the like.

The sheet for deodorizing and removing harmful substances according to the present invention may be used as a deodorant in refrigerators and automobiles, as a deodorant for shoes, a cleaning plant (garbage incineration plant), It can be used as a deodorant in hospitals.

When the sheet is realized as paper by the method shown in FIG. 4 or FIG. 5, it can be realized as not only the above-mentioned various products but also various paper products. Examples include shoji, sliding doors, wallpaper, screens, folding screens, packaging materials (wrapping paper),
Paper curtains, paper blinds, furniture underlays, shoe underlays, etc.
