Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a plan view schematically showing a bedsore prevention sheet 10 as the bedsore prevention article of the present invention. C The bedsore prevention sheet 10 is made of nonwoven fabric or paper, and will be described later. It is composed of a special liquid impregnated and then dried. In other words, the sheet made of this nonwoven fabric or paper has its own deodorizing and harmful substance removing effects. Therefore, the above-mentioned special liquid is impregnated. The bedsore prevention sheet 10 is placed between the bed or the futon and the sheets above it., Fig. 2 shows the bedsore prevention sheet 10 of Fig. 1 laid under the sheets 12 It is a top view which shows a state typically. For ordinary single size futons and beds, the width is about 80-90 cm and the length is about 90-150 era. The bedsore prevention sheet only needs to be laid between the futon or bed and the seat, but in order to prevent the beds from slipping, it is fixed to the sheet, futon, bed, etc. with Velcro. You may do so.

FIG. 3 is a diagram showing a manufacturing process of the bedsore prevention sheet shown in FIG. The bedsore prevention sheet of the present invention has found a new use of the deodorizing and harmful substance removing sheet that the present inventor has already developed in order to remove odorous substances from indoor odors and new building materials. The sheet itself is the same as the sheet for deodorization and removal of harmful substances that has already been developed and for which a patent application has been filed (Japanese Patent Application No. 11-213733). FIG. 3 is a process chart showing a first embodiment of a method for producing a sheet for deodorizing and removing harmful substances. That is, Fig. 3 shows an apparatus and a process for manufacturing 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 roll 20A of the sheet (nonwoven fabric or paper) before impregnating with the deodorant and harmful substance remover is indicated by an arrow Ml in the figure by rollers 22 to 28. It is conveyed as shown, and is finally wound up to form a socket 20B.

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. Container 46 holds liquid deodorant and harmful substance remover, and valve 48 opens This deodorant and harmful substance remover 50 is poured into the lower sponge member 42. _c Below the sponge member 42, there is another sponge member 4 sandwiching the sheet 20. 0, and these two sponge members 40, 42 are opposed to each other at a predetermined pressure by a mechanism not shown.

The deodorant and harmful substance removing agent 50 poured down from the container 46 is contained in these sponge members 40 and 42, and when the sheet 20 is transported between them, the liquid is in a liquid state. The sheet 20 is impregnated with 50 of the deodorant and harmful substance removing agent. The sheet 20 is conveyed in a zigzag manner by a plurality of rollers 30 to 38 because the sheet 20 that is wet by the hot air 54 from the heater 52 is dried. It is. Before or after this drying step, the sheet 20 is irradiated with the gamma ray 58 generated by the gamma ray irradiation device 56. The illustrated embodiment shows a case where gamma rays are irradiated after the drying step. By the irradiation of the gamma rays, the previously impregnated deodorant and harmful substance remover 5 ° is graft-polymerized. After the drying is completed, the conveying speed and the winding speed are controlled so that the roll 20 is wound up.

As the liquid deodorant and harmful substance remover 50, a deodorant and harmful substance remover for Daraf polymerization is used. The deodorizing agent and harmful substance removing agent for the graft polymerization is obtained by introducing a functional group into the graft chain, and a cation exchange group or a sulfonic acid group and a carboxyl group can be used as the functional group. . A deodorant using a cation exchange group is disclosed in Japanese Patent Publication No. 7-79593. Specifically, a molded article composed of a base material composed of pulp and Ζ or polyolefin is a cation-exchange agent. It has an exchange group. In order to produce such a cationic deodorant, a reactive monomer is graft-polymerized on a molded article. Also, sulfonic acid The deodorizer using Kimoto and Rubixil Grave is a pulp ball-based deodorizing material described in the May 1993 issue of Environmental Technology (Vol. 22 No. 5) pp. 22-25. The performance evaluation ffi j shows that sulfonic acid groups and carboxy groups were introduced into cellulosic pulp balls by gamma-ray simultaneous irradiation polymerization.

These graft polymerization deodorants and harmful substance removers deodorize and detoxify the odor-causing substances and harmful substances by chemical reaction with the odorous substances. The principle of deodorization is different from physically adsorbing the causative substance. Therefore, after the chemical reaction with the specified amount of malodorous substance, the graft deodorant and harmful substance remover does not react any more, but adsorbs a certain amount of the substance causing the malodor, as with activated carbon. Then, the saturated substance is not released. The amount of time required to cause a chemical reaction with a certain amount of the odor-causing substance varies depending on the quality and quantity of the odor-causing substance, and is not constant. In a typical house, the chemical reaction effect lasts for about three to six months, but harmful formaldehyde, toluene, xylene, wood preservatives, plasticizers, termiticides, etc. are used for the first few days. It can be almost completely removed in a few weeks.

In the sheet manufacturing process shown in FIG. 3, a sheet 20 is prepared in advance, and a deodorizing effect is imparted to the sheet 20. However, deodorization is performed at the stage of manufacturing the sheet as paper. It can also add the effect of removing harmful substances. 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 pulp is charged. At this time, in addition to the usual pulp of paper raw material, a deodorant and harmful substance remover made by the graft polymerization method using pulp as the base material was used as a solid raw material. Add. These two types of raw materials are stirred in step S2. Then, as in the normal paper manufacturing process, beating (step S3), adding water (step S4), further beating (step S5), making paper (step S6), drying (step S6) Paper is manufactured through each step of S7).

In the flow shown in Fig. 4, the deodorizer and harmful substance remover made by the graft polymerization method in the initial raw material input stage (step S1), which uses pulp as the base material, was originally used. Although it is mixed with the raw material, the deodorizer and harmful substance remover made by the graft polymerization method using pulp as the base material is a fiber that has been finely cut in advance. It may be mixed between step S3 and step S4 of this flow.

That is, FIG. 5 is a modified example of the flow of FIG. 4, in which pulp as the first raw material, which is the original raw material of paper, is charged in step S1A, and the second raw material after beaten (step S3). Then, a deodorizer and harmful substance remover made by the graft polymerization method using pulp as the base material is injected (Step S1B). After that, stirring (Step S2), water addition (Step S4), further beating (Step S5), papermaking (Step S6), and drying (Step S7) are performed, and the flow shown in FIG. Similarly, paper is produced.

Deodorizers and harmful substances removers made by the graft polymerization method using pulp as the base material are mixed at a fixed ratio to the original raw material, but the finished paper is 1 square meter. If it is mixed in several tens of grams per unit, it will have a practical deodorizing and harmful substance removing effect. In particular, deodorizers and harmful substance removers made by the graft polymerization method, which use pulp as the base material, have the chemical action, that is, the deodorizing and harmful substance removing effect, even if they are cut finely. Because it does not change, As shown in Fig. 10, even when mixed into the raw pulp, the effect is exhibited. The methods in Figs. 4 and 5 differ from the method in Fig. 3 in that paper is manufactured from the beginning, but when compared on the finished product basis, Figs. 4 and 5 are less expensive. _c

The sheet of the present invention manufactured by the method shown in FIGS. 3 to 5 has a structure in which the sheet itself is laid under sheets as a bedsore prevention sheet as shown in FIG. It can be processed into sheets, and various products such as futons, beds, or the fabrics that make up the bed pad, and their underlying fabrics.

In the above embodiment, a sheet-like bedsore prevention article made of non-woven fabric or paper has been described. However, such a sheet may be a cloth instead of a non-woven fabric. Rather than impregnating with a deodorant and harmful substance removing agent after weaving, it is better to impregnate the deodorant and harmful substance removing agent in the state of the yarn before weaving and perform the graft polymerization. The same method as that shown in Fig. 3 can be applied to impregnate the yarn with a deodorizer and a harmful substance remover, and to carry out the polymerization. Industrial applicability

As described above, according to the present invention, a sheet made of non-woven fabric or paper is impregnated with a liquid deodorant and harmful substance remover and irradiated with gamma rays for graft polymerization.ぴ The duration of the harmful substance removal effect is extremely long, and by applying it to bedding, etc., it is possible to remove odorous substances and harmful substances around the body of a bedridden patient for a long period of time. This can effectively prevent bedsores caused by the bed. In addition, when making paper, the pulp used as a raw material is graft polymerized. By mixing pulp into the substrate, a deodorant and harmful substance remover made by the product, the duration of the deodorant effect and harmful substance removal effect is extremely long, and it can be applied to bedding etc. Thus, the same result can be obtained at low cost. Further, the yarn for weaving the fabric is impregnated with a deodorant and a harmful substance remover, and is irradiated with gamma rays for graft polymerization, and the same effect is obtained by using the fabric composed of such a yarn in the same manner. be able to.
