INDUSTRIAL APPLICATION FIELD The present invention relates to a filling object having a deodorizing effect, and more specifically to a futon, a pillow, a cushion, which has the effect of eliminating various bad odors generally called daily life odors, especially bad odors during the rainy season or summer. Concerning stuffed objects such as stuffed animals. Conventional technology Normal textile products have a large surface area per unit weight, so they tend to absorb odors. For example, if you stay in a room filled with cigarette smoke for several hours, the cigarette smell will stick to your clothes and be difficult to remove. It is a common experience that there is no such thing. Among textile products, stuffed objects have a particularly high air content filled with fibers inside the fabric, so they have an even stronger odor absorption effect, so when you stay at an inn, you may notice an indescribably unpleasant odor coming from your futon. Or,
This is why when you visit other people's homes, you may experience the smell of socks around the kotatsu. In addition, in the case of bedridden patients, they tend to dry their bedding outdoors or wash it less frequently, which can cause a bad odor to fill the bedding and even the room, making it difficult for children to come near them. Many cases have also been reported. These cigarette odors, human body odors, urine odors, and the like are usually felt particularly strongly during the rainy season or summer. To solve this problem, activated carbon, which has high adsorption properties, has conventionally been mainly used as a deodorant.
For example, a mat in which activated carbon is sealed inside the filling object has been proposed (Japanese Utility Model Publication No. 124713/1983).
Alternatively, a pillow has been proposed in which a bag filled with activated carbon is provided (Japanese Utility Model Publication No. 124717/1983). Additionally, a mattress made of activated carbon processed into a sheet is commercially available (“Katsusei” manufactured by Yasuya Co., Ltd.). However, activated carbon has a high adsorption capacity and has a deodorizing effect in a dry atmosphere, but when it absorbs moisture, the adsorption capacity rapidly decreases, and the deodorizing effect is also drastically reduced. It is also known that once adsorbed odor components (malodors) are re-released as the temperature changes. Furthermore, when activated carbon is used, there is a problem that no matter how much effort is put into its shape, the properties such as elastic recovery, lightness, flexibility, and bendability, which are basically required of a filling object, will be significantly reduced. It was hot. Purpose of the Invention In view of the above-mentioned circumstances regarding deodorizing fillings, the object of the present invention is to provide a long-lasting deodorizing effect on the filling object and the bad odors generated around the filling object, especially the bad odor occurring under high humidity. It also has the cushioning properties, drape properties, heat retention properties required for stuffed objects,
To provide a deodorizing filling body whose performance such as breathability is maintained as it is. Structure of the Invention That is, the present invention provides (1) a deodorizing filling object comprising fibers to which a deodorant has been applied, characterized in that a water-soluble deodorant and a hydrophilic compound coexist. (2) The deodorizing filler according to claim 1, wherein the fibers are coated with a hydrophilic compound. (3) The deodorizing filling object according to claim 1 or 2, wherein the water-soluble deodorant is an isolated substance from a plant of the Camellia family. (4) The deodorizing filling object according to any one of claims 1 to 3, wherein the fibers are microporous fibers. Here, water-soluble deodorants do not simply refer to water, but also deodorants that dissolve in hydrophilic organic solvents that have a high affinity with water, such as methyl alcohol, ethyl alcohol, propyl alcohol, acetone, and ethyl acetate. means. For example, tea, sasanqua, camellia,
These include liquid distillates obtained by extraction and separation from the leaves of plants of the Camellia family, such as Sakaki and Hisakaki (Japanese Patent Application Publication No.
53-66434, JP-A-58-61751). Furthermore, water-soluble deodorants such as "Noncent" or "Nonsumel" (manufactured by Riverside Chemical Co., Ltd.) and "Air Wick" (manufactured by Omi Brothers Co., Ltd.) are known as commercially available products. The fibers to which the deodorizing agent is applied may be any material that has been conventionally used for stuffing. For example, natural fibers such as cotton and feathers,
These include cellulose-based semi-synthetic fibers, synthetic fibers made of polyester, polypropylene, polyacrylonitrile, polyvinyl chloride, etc. The fibers may have a round cross section, hollow fibers, irregularly shaped hollow fibers, or the like, but irregularly shaped hollow fibers are preferred in order to enhance the deodorizing effect and improve the durability of the deodorizing effect.
Further, as for the fine structure of the fiber, it is preferable that the fiber has micropores, and the micropores communicate from one end of the fiber to the other end. The degree of hollowness must be 50% or less by volume of the entire fiber, including the micropores. 50
If it exceeds %, the hollow part will be crushed and the resistance to set will be extremely reduced. Further, as the fiber form, long fibers such as opened crimped tow may be used, or short fibers may be carded. The finer the single yarn denier, the greater the surface area per unit weight, which can increase the amount of deodorant attached, but if the denier is less than 3, the inherent properties of the stuffed object, such as cushioning properties,
This is not preferable because it reduces bulk and durability. Furthermore, the fibers to which the deodorant is applied preferably have hydrophilic properties. Examples include cotton, cellulose-based synthetic fibers, or hydrophobic synthetic fibers to which a hydrophilic compound has been added. Examples of hydrophilic compounds include methoxypolyethylene glycol ester of acrylic acid or methacrylic acid (degree of polymerization of polyethylene glycol is 1 to 20), polyoxyethylene glycol dimethacrylate (molecular weight 250 to 1500), polyoxyethylene glycol diacrylate (molecular weight 250 ~
1500) (Japanese Unexamined Patent Application Publication No. 1983-
Publication No. 4775). To give a specific example of a deodorizing filling material, for example, after adsorbing 0.1% by weight or more of a polyoxyethylene glycol diacrylate compound onto carded irregularly shaped hollow microporous polyester short fibers with a hollowness degree of 20%, It is preferable to use the fibers sprayed with a water-soluble deodorizing agent as the filling material. Addition of a polyoxyethylene glycol diacrylate compound has the effect of increasing the durability of the deodorizing effect of the water-soluble deodorant. The relative humidity inside the stuffed body is 15% in a stuffed body made of fibers coated with a water-soluble deodorizing agent.
It is preferable to keep above RH, preferably 40
%RH or higher. That is, in the case of a water-soluble deodorant, it is necessary for an appropriate amount of water to coexist with the deodorant in order to exhibit the deodorizing effect, and the conditions for developing the deodorizing effect are completely different from those in the case of activated carbon. The effect of allowing moisture to coexist with a deodorant is shown in Figure 1. In Figure 1, the horizontal axis shows relative humidity [RH (%)], and the vertical axis shows deodorization rate. As is clear from Figure 1, the deodorizing effect is 15%R.
Rapidly increases under atmospheric conditions of H. 1, 40% R.
At H. or above, the deodorizing effect reaches over 95%. The method for measuring the deodorization rate is as follows. Measuring method for deodorizing rate A 5000cm3 airtight container was filled with a fixed concentration of malodorous gases such as ammonia, trimethylamine, hydrogen sulfide, etc., and at the same time a fixed amount of deodorizer was added, and the relative humidity inside the container was changed under atmospheric conditions. After a certain period of time, the gas in the container was taken out, and the concentration was measured by neutralization titration with acid or alkali depending on the type of test gas, and the deodorization rate of the test gas (malodorous gas) was determined. Note that hydrogen sulfide was absorbed into a caustic soda aqueous solution and measured by the iodine reduction method. Next, a method for manufacturing the deodorizing filling object of the present invention will be explained. First, water-soluble deodorants may be used as long as they are soluble in hydrophilic solvents, including water, as mentioned above, but for example, they can be obtained by extracting and separating the leaves of plants of the Camellia family, such as camellia. A 20% aqueous solution of a liquid distillate (Fresh Shiramatsu FS-500; manufactured by Shiraimatsu Shinyaku Co., Ltd.) is preferably used. As a method for applying the water-soluble deodorant to the fibers, conventionally known methods such as a dipping method and a spray method may be used. Fibers to which the deodorant can be applied include hydrophilic natural fibers such as cotton, and microporous fibers (Japanese Patent Application Laid-Open No. 56-20612, JP-A-57
11212), microporous polyester fibers with an irregular hollow cross section, or polyester fibers treated with hydrophilic treatment are preferably used. As another method of applying a deodorant, a method has been proposed in which a deodorizing component is coexisted using a clay material with a specific gravity of 1.60 to 1.64 and a pore volume of 0.32 to 0.41 cc/g as a medium (Japanese Patent Application Laid-Open No. 1983-1999). When this method is used, it is necessary to fix the powder of the unglazed material containing the deodorizing component to the fiber surface using a binder, which reduces the processability of cotton filling production. The method for producing the deodorizing filler of the present invention involves grinding a water-soluble deodorant into fine particles with a particle size of 1.0μ or less, preferably 0.1μ or less, and then forming a microporous powder in the form of an emulsion or suspension. It is also possible to use a method in which fine particles of deodorant are adsorbed inside fibers by applying them to fibers, microporous fibers with irregular hollow cross sections, or amorphous fibers, but in order to increase the efficiency of applying deodorant to fibers, It is preferable to apply the deodorant in liquid form (for example, in solution form). A conventionally known method may be used for manufacturing the filling object. That is, the drawn tow was crimped and heat set, then cut to form short fibers, and then carded to form a web. The timing of applying the deodorant is not particularly limited, but if it is applied in liquid form, it is preferable to apply it immediately before cutting. Next, in the present invention, it is necessary to maintain the moisture content (relative humidity) in the side of the deodorizing filling material at a certain level or more. This is because water-soluble deodorants do not exhibit their deodorizing effect unless a certain concentration of water is present. The present inventors have discovered that in order for a water-soluble deodorant to exhibit a deodorizing effect, the coexistence of moisture with a relative humidity of at least 15% RH (relative humidity) is essential. As a result of further detailed investigation, we found that in order to achieve the desired deodorizing effect, it is desirable to coexist with moisture at a RH of 40% or more. 15% relative humidity in the side area
In order to maintain RH or higher, preferably 40%RH or higher, the following method is used. For example, there is a method in which the fibers to which a water-soluble deodorizing agent is applied are themselves highly hydrophilic fibers and the fibers themselves contain water. For this purpose, for example, the fibers can be made into a unique hollow microporous shape to absorb moisture, or the fibers can be coated with a hydrophilic polymer.
There is a method of semi-chemically attaching water by adding hydrophilic groups to the fiber surface and using a polar effect. Hydrophilic polymers include N-methylol acrylamide polymer, ethylene bisacrylamide polymer, polyoxyethylene-polyoxypropylene polymer (molecular weight 600-800), dimethylaminomethyl methacrylate polymer, polyoxyethylene-containing acrylate polymer, and polyoxyethylene-containing polymer. Examples include methacrylate polymers, polyethylene glycol-polyethylene terephthalate copolymers, and the like. In order to apply the hydrophilic polymer to the fibers, a coating method in a solution state, a spray method, an impregnation method in a solution or suspension state, a spray method, etc. can be used. For example, the above-mentioned hydrophilic compound may be applied to the fiber alone, or may be used in combination with a hydrophilic spinning oil. Examples of hydrophilic spinning oils include alkyl phosphate salts such as potash cetyl phosphate, polyhoxyethylene (additional moles of 2 to
20) It is recommended to use alkyl ether phosphate salts. The side material used for the stuffing object may be one commonly used. Example 1 An undrawn polyethylene terephthalate yarn having a single yarn denier of 6 denier was drawn, crimped, and heat set to form a tow of 400,000 denier. Immediately before cutting the tow into short fibers, a 20% aqueous solution of a deodorant was applied by spraying so that the adhesion rate was 0.1% by weight based on the weight of the fibers of the tow. As a deodorant, Fresh Shiramatsu FS-500 (manufactured by Shiraimatsu Shinyaku Co., Ltd.) was used. The fibers after spraying were applied to a carding machine to create a web. This web was covered with a fabric side made of polyethylene terephthalate fibers to form a deodorizing filling. The deodorizing efficiency was measured after leaving the deodorizing stuff together with 5000 ppm of trimethylamine in a sealed container for 10 minutes under the atmospheric conditions of temperature and relative humidity shown in Table 1. )/C 0 ×100 was investigated. The results are shown in Table 1. (The deodorizing efficiency was calculated as (C 0 −C)/C 0 ×100.
C 0 is the trimethylamine concentration before leaving, C
is the trimethylamine concentration after standing for 10 minutes. ) Example 2 An aqueous solution of cetyl phosphate potash (oil agent for the spinning process) and polyethylene glycol (hereinafter referred to as PEG, 10 molar adduct) was added to an undrawn yarn of polyethylene terephthalate with a single yarn denier of 6 deniers so that the weight of the PEG was increased. After applying by dipping method so that the adhesion rate is 3.0% by weight, stretching, crimping,
The tow was heat set to have a total denier of 400,000 deniers. Immediately before cutting the tow into short fibers, a 20% aqueous solution of a deodorant was applied by spraying so that the adhesion rate was 0.1% by weight based on the weight of the fibers. The deodorant is Fresh Shiraimatsu FS-
