[Field of Industrial Application] The present invention relates to a deodorizing futon, particularly a deodorizing futon that is suitable as bedding for people who have difficulty in self-management of toilets, such as physically disabled people, bedridden patients, or bedwetting people. . [Prior Art] In many cases, hygroscopic fibers are used for the filling of mattresses or comforters that are generally used as bedding. Since the cotton wadding is shaped by the cohesion of the fibers, it cannot be easily washed, and odors accumulate during long-term use. For this reason, futons are sometimes dried and used repeatedly, but since it is difficult to dry futons frequently when used by hospital bed patients, it is inevitable that odors will accumulate over time. In order to prevent the accumulation of such odors, bedding lined with activated carbon has been proposed, as seen in, for example, Japanese Utility Model Application Publication No. 81667/1983. [Problems to be solved by the invention] However, especially for people who have difficulty in self-management of defecation, such as physically disabled people, bedridden patients, or bedwetting patients (hereinafter simply referred to as patients), there are cases where the defecation is not handled by a caregiver. In such environments, during long-term medical treatment, the odor of excrement permeates the futon, and the unpleasant odor emanates from the futon, creating a strange odor throughout the room. This phenomenon can be improved to some extent by incorporating the above-mentioned activated carbon into the futon, but the effect is initially temporary and no long-term deodorizing effect can be expected unless the activated carbon layer is replaced even at short intervals. As a result, the bedrooms of long-term care patients are not only full of odors, even more so than the patients are aware of, but the odor also permeates the patients themselves. This becomes a major factor in alienating patients by making visitors and nurses feel uncomfortable, and causes social harm in that patients gradually become closed-minded and their personalities become more sinister. The present invention provides a deodorizing futon that is suitable for the above-mentioned medical patients, has a function of eliminating odors caused by leakage of urine water, and can maintain deodorizing effect for a long period of time. be. [Means for Solving the Problems] The deodorizing futon of the present invention is such that at least a portion of the cotton stuffing wrapped in the futon side material exhibits an excellent deodorizing effect against excrement and urine odor, and A fiber with long-lasting action, that is, a metal complex with redox ability,
It is composed of A fibers which carry more than % by weight of metal ions and B fibers which carry metal ions. As the metal complex which is the deodorizing component of A fiber, metal porphyrin, metal porphyrazine and derivatives thereof having redox ability are used, and are carried in physical contact with the fiber component,
They are chemically bonded and supported to form a polymer metal complex. Metalporphyrin and its derivatives are represented by the structural formula shown in FIG. Metal porphyrazine is represented by the structural formula shown in FIG. In both formulas, M is Fe, Co, Mn,
Examples include metals such as Ti, V, Ni, Cu, Zn, Mo, and W. Among these metals, iron and cobalt are preferred from the viewpoint of deodorizing effect. In both formulas, X represents hydrogen or a substituent. Examples of substituents include alkyl groups, substituted alkyl groups (e.g. chloromethyl group),
Halogen group, nitro group, amino group, azo group, thiocyanate group, carboxyl group, carbonyl chloride group, carboxylamide group, nitrile group, hydroxyl group, alkoxyl group, phenoxyl group, sulfonic acid group, sulfonyl chloride group, sulfonamide group, thiol Examples include alkali salts of carboxyl groups and sulfonic acid groups, as well as alkyl silicon groups, vinyl groups, and the like. These can be used alone or in combination
More than one species is used. Among these, carboxyl groups, sulfonic acid groups, alkali salts thereof, amino groups, halogen groups, hydroxyl groups, and the like are preferably used. The most preferred specific examples of metal complexes having redox ability are cobalt phthalocyanine octacarboxylic acid, cobalt phthalocyanine tetracarboxylic acid,
Iron phthalocyanine octacarboxylic acid or iron phthalocyanine tetracarboxylic acid. The above metal complexes may be used alone or in combination of two or more. The required amount of metal complex supported varies depending on the type of metal complex, but is generally 1% by weight or more. The larger the supported amount, the more deodorizing activity will be obtained; if the supported amount is smaller, the desired level of deodorizing activity will not be obtained, and the sustainability of the deodorizing activity will also be poor. However, there is a limit to the amount that fibers can support metal complexes, and the preferred amount is 1 to 20% by weight.
is within the range of The metal ions supported on the B fibers are preferably transition metal ions, such as copper, iron, cobalt, and nickel, while metal ions other than transition metals are preferably calcium, barium, and magnesium. The metal ions to be supported may be used alone or in combination of two or more. Although it is desirable that the amount of metal ions supported be as large as possible, from the viewpoint of economy and the strength and shape retention of the supported fibers, about 0.1 to 20% by weight is appropriate. The above-mentioned metal ions may be supported by directly physically contacting the fibers, or may be supported by being chemically bonded to the polymers of the fibers. In the latter example, a polymer metal complex is formed by an intramolecular chelate complex of polyvinyl alcohol and copper ions, a complex of polyvinylamine and iron ions, etc. Further, the compound containing the metal ion may be carried by physically contacting the fiber, or may be carried by being chemically bonded to the polymer of the fiber. Examples of the metal complex-supported fibers and metal ion-supported fibers include regenerated cellulose fibers, hygroscopic synthetic fibers, porous fibers, and porous hollow fibers, but especially fibers with a primary swelling degree of 150
~500% regenerated cellulose fiber is preferred. [Function] The A fibers constituting at least a part of the batting of the futon of the present invention oxidizes and decomposes malodorous substances such as hydrogen sulfide and mercaptan by the action of a metal complex having redox ability. Becomes odorless. That is, the metal coordinated with the porphyrin and porphyrazine rings serves as an active center, and the oxidation reaction proceeds. For example, taking the oxidation of mercaptan as an example, the oxidation is shown by the following chemical reaction formula. 2R−SH＋2OH − →2R−S − +2H 2 O …(1) 2R−S − +2H 2 O＋O 2 →R−S−S−R+H 2 O 2 +2OH − …(2) Produced by the reaction of formula (1) The thiolate anion coordinates with oxygen to porphyrin and porphyrazine to form an active species that is a ternary complex. The thiolate anion coordinated to this active species is dimerized into a disulfide shown in formula (2) via a thiyl radical, and is incorporated into the fiber, making it odorless. This reaction is very similar to in vivo enzymatic oxidation reactions. All oxidation reactions by enzymes are aerobic reactions. That is, most of them perform oxygen oxidation reactions. Examples of oxidation reactions of odor-like substances by oxidizing enzymes include those shown in the following table.

Example 1 A rayon staple with a primary swelling degree of approximately 240% and a length of 31 mm is immersed in an aqueous solution of iron phthalocyanine/polycarboxylic acid (aqueous solution concentration 3 g/, PH 12), then dehydrated and dried to form iron phthalocyanine/polycarboxylic acid of approx. A fiber carrying 2% by weight was obtained.
The above rayon staple was immersed in an aqueous copper acetate solution (aqueous solution concentration: 5 g) and then dehydrated and dried to obtain B fibers carrying about 2% by weight of copper acetate. 35% A fibers, 35% B fibers, and commercially available polyester. 30 cotton
% cotton mixture was used as cotton wadding, and 5 kg of the wadding was covered with highly breathable geodetic material to make mattresses and comforters. Several sets of futons were then used as bedding for several patients who were isolated in separate rooms. As a result, even though the product has been used continuously for about 6 months, no strange odor was observed, confirming the deodorizing effect and its sustainability. Example 2 A mattress with an apparent thickness of about 3 cm was made by layering 65% A fiber and 35% B fiber obtained in the above example and wrapping it with a highly breathable side material, and making a mattress for children with bedwetting. used. After drying the futon each time it became wet with urine and using it repeatedly for six months, the futon had almost no odor. Example 3 A rayon staple is immersed in cobalt chloride (aqueous solution concentration 10 g/) and then dehydrated and dried to obtain B fibers carrying approximately 3% by weight of cobalt chloride. A mattress with an apparent thickness of about 3 cm was made by layering 65% of the A fiber obtained in the above example and 35% of this B fiber and wrapping it in a side fabric with good air permeability. Similar results as in Example 2 above were obtained. Example 4 Ferrous acetate (aqueous solution concentration) on rayon staple
After soaking in 20g/), dehydrate and dry and add acetic acid.
B fibers carrying approximately 5% by weight of iron were obtained. 65% A fiber obtained in the above example and 35% B fiber
A mattress with an apparent thickness of about 3 cm was created by layering the sheets and wrapping them with a highly breathable side fabric. Similar results as in Example 2 above were obtained. [Effects of the Invention] As described above, in the deodorizing futon according to the present invention, the A fibers constituting the batting wrapped in the side material carry a metal complex having redox ability, and the B fibers carry metal ions. As a result, mercaptans, aldehydes, etc. are oxidized, indoles, etc. are cleaved, ammonia, amines, etc. are absorbed, and the absorbed ammonia and amines are further decomposed by metal complexes. This eliminates odors such as urine and sweat. Its deodorizing effect is not simply due to absorption, nor is it due solely to decomposition, but because these two effects are linked, it is fast-acting and lasts for a long time. Therefore,
It is particularly effective as a futon for long-term care patients.
