2. Description of the Related Art In recent years, the increase in allergic diseases has become remarkable, and in particular, the increase in atopic diseases in children has become a social concern. It is said that the increase in these allergic diseases includes changes in the living environment, changes in eating habits, increases in harmful substances such as air pollution, changes in the mental environment (increases in stress), and increases in allergic predisposition (genetic). In environmental changes, it is thought that the accumulation of indoor mites and antigenic substances derived from indoor ticks due to the hermeticity of the house and the warming and humidification are greatly involved. Living Environment ", 1995
March, page 2-3). In fact, the positive rate of skin test for major indoor allergens (allergen antigens) reached more than 70% in the 20-year-olds, and 60 in the average for those 40 and younger.
%. 80-9 for younger people, including children
0% are positive for house ticks (Akiyama et al., Allergy, Vol. 43, pp. 9-15, 1994; Ishizaki et al.,
Allergy, Vol. 41, pp. 668-675, 199
2 years). There are many types of mites that live indoors, but around 70% of dust mites (74%), house mite (13%), ticks (5%), mites (2%), and mites (2%) In recent years, the percentage of dust mites has been increasing. The house dust mites include Dermatophagoides farinae and Dermatophagoides pteronyssi.
nu)), and all of them have been attracting attention as allergens (allergens) (Ministry of Health and Welfare Allergic Research Project Housing Group Report “Allergy and Living Environment”, March 1995, pp. 8-9).

[0003] Indoor ticks, mainly dust mites, mainly consist of floors (flooring, tatami, carpets), sofas, chairs,
It lives in the dust and dust on the surface of the bedding and multiplies proteinaceous dirt and dust in the bait. It is said that tatami, sofas, chairs, bedding, etc. have a strong proliferation inside. Although the number of mites that inhabit with dust and dust on each material varies greatly depending on the environment in which they are placed, the number of live mites per square meter is as shown below. Tatami surface 65 ± 76
Head, carpet 3100 ± 6000, flooring 4
8 ± 23 heads, 113 ± 69 futon surfaces; the number of mites detected from the surface of the tatami varies depending on the season, from 80 in summer to 3 in winter
0 (Midori Yoshikawa, Sumi Science-1991, Autumn, pp. 28-32, 1991). On the other hand, according to Irie et al., The average value in summer was 150 tatami mats and 2 carpets.
30 animals and 40 wooden floors (Irie et al., Air Purification, Vol. 30, No. 5, pages 395-399, 1
993). According to Hirose, the average annual number is 116 tatami mats and 1,326 carpets (Yoshi Hirose, Life and Environment, October 1990, page 59-6).
5, 1990).

In Europe, the number of house mites that are an important cause of allergic diseases is estimated to be 100 per gram of dust.
Head is a hygiene standard (Korsgaard J., Thi
rdCongress of the European Society of
Pneumology, Basel, 16; September 1984;
Kniest F. M. , Environment International,
Vol. 15, pp. 197-201, 1989). According to a report by Fujimoto et al., Indoor dust was collected from tatami floors of 20 wooden houses in Japan, and an average of 1060 animals / g (maximum value of 3180) was collected.
(Minimum 140 heads) mites are detected (Environmental Management Technology, Vol. 4, No. 5, pages 286-290, 198)
6 years). Although there are natural differences between Europe and Japan,
In particular, tatami surfaces may be home to mites that greatly exceed European sanitary standards. If the floor is cleaned with a rag, mop, or other wiper in such an environment to remove dust and dust, most of the mites that live on the floor are absorbed and retained by the cleaning tools used. Will be. At the same time, the cleaning tool holding the mites also adsorbs and retains proteinaceous dust, which is the food of the mites, and these are collected at an appropriate temperature (about 20-30 ° C) and humidity (60-80 ° C).
%), It is clear that mites proliferate rapidly. If such cleaning tools are used again to clean the interior of the room, many mites will be scattered around the room, and they will proliferate everywhere. Seems to be a problem. In addition, it is easy to imagine that a similar phenomenon occurs in a dust collection bag in a vacuum cleaner when dust or dust is sucked by the vacuum cleaner. Therefore, it is considered that a large amount of antigenic substances (allergens) derived from dead bodies and feces are generated from the mites that have multiplied. In such a case, it is said that the vacuum cleaner used in ordinary households traps only about 70% of the fine particles of 0.3-1.0 μm, and the fine particle mite allergen is re-distributed indoors from the exhaust port. there is a possibility. In recent years, in addition to vacuum cleaners, various cleaning tools such as chemical rags, mops, nonwoven fabrics, and paper that have been treated with adsorbents that do not use water have been used to clean the floor. Was never paid.

[0005]

In order to reduce the indoor concentration of mite allergen, which is important as an allergen antigen substance (allergen), and to maintain a comfortable and healthy life, it is necessary to remove mites and mite allergen itself. Of course. However, due to interest in increasing allergic diseases in recent years, it is desired that cleaning tools used for removing dust and dust including allergens do not amplify and diffuse mite allergens.

[0006]

According to the present invention, there is provided a cleaning tool for indoor use, wherein mite-preventing treatment is carried out on the surface or inside of the cleaning tool. It is. A second aspect of the present invention is the cleaning tool according to the first aspect, wherein the cleaning tool is obtained by treating a chemical having an acaricide activity and / or an activity of inhibiting mite growth. A third aspect of the present invention relates to a mineral oil or a synthetic lubricating oil, 0.1 to 10% by weight of a non-cationic surfactant and 0.1 to 10% by weight.
3. The cleaning tool according to claim 2, wherein the cleaning tool is treated with an oil containing an agent having an activity of killing mites and / or inhibiting the growth of mites in an amount of from 01 wt% to 50 wt%. In a fourth aspect of the present invention, the cleaning tool is a mop,
The cleaning tool according to claim 3, which is one of a cloth and a nonwoven fabric.

[0007]

According to the present invention, the above objects (objects) are achieved by providing a cleaning tool that does not allow indoor ticks to multiply on the surface or inside thereof. The cleaning tool 1 shown in FIG. 1 includes a handle 2 and a mop 3, and the mop 3 is treated with an agent having an acaricide activity and / or a mite growth inhibitory activity.

[0008] Cleaning tools for adsorbing and holding dust mites together with dust and dust indoors include cotton cloth, rayon, synthetic fiber cloth such as polyester, nylon, acrylic and vinylon, mop-shaped fibers, rayon,
Sheets made of non-woven fabric made of vinylon, nylon, polyethylene, polypropylene, etc., and paper-like materials made of pulp, vinylon, rayon, and other synthetic fibers, and to enhance the ability to absorb and hold dust and dust on them An organic compound which has been treated or physically treated is used. As the organic compound that enhances the ability to retain and retain dust and dust, lipophilic oily substances such as liquid paraffin, hydrophilic liquid polymers such as polyethylene glycol, and water itself are used. These compounds include a surfactant for facilitating treatment and attachment to the fiber. Antibacterial agents and antifungal agents are also effective. It is also possible to use a product to which an electric charge is added in order to physically increase the adsorption and holding power. On the other hand, besides the cleaning tool that adsorbs and holds dust and dust, a suction tool such as an electric vacuum cleaner that collects dust in a dust collecting bag can also be cited as a cleaning tool that holds ticks together with dust and dust.

The cleaning tool of the present invention which does not propagate indoor ticks on the surface or inside thereof is, for example, a cleaning tool which adsorbs and retains dust and dust in the above-mentioned room, has an acaricidal activity and / or an activity of suppressing the growth of ticks. It can be easily manufactured by treating with a drug possessed.

Many other compounds having acaricidal activity are also known, and various essential oil components (Japanese Journal of Pharmaceutical Sciences, Vol. 43, No. 2,
Pages 163-168, 1989) and perfume ingredients (arom
atopia No. 9, pages 65-67, 1994) can also be used for the purposes of the present invention.

However, the conventional typical acaricides such as organophosphorus and carbamate drugs are generally highly toxic, and their use must be restricted in consideration of the use state and location. When actually selecting a treatment agent, it is highly safe for the human body, can be easily used anywhere in the room, and has excellent acaricidal activity and growth inhibitory activity against a wide range of indoor mites including Dermatophagoides, which are important as allergens It is desirable to use a drug that has a high economical efficiency.

These drugs may be used alone or as a mixture of two or more drugs. In addition, especially for pyrethroids, a synergist such as piperonyl butoxide is used together to enhance the activity of the drug. Depending on the drug used, various synergists and stabilizers enhance the activity and improve the stability. It is used simultaneously for the purpose of enhancing residual effect. The treatment amount of the medicine varies depending on the activity of the medicine, but is 0.001 to 10 wt.
%, Preferably 0.005% to 1% by weight.

When the cleaning tool is made of a cloth, a mop, a nonwoven fabric, a sheet, or the like, an agent having an acaricidal activity and / or an agent having an activity of inhibiting the growth of mites is preferably used in an amount of 0.1 to 5%.
Carriers that are liquid at a concentration of 0%, for example, aliphatic hydrocarbons such as hexane, kerosene, and kerosene; halogenated hydrocarbons such as dichloroethane and carbon tetrachloride; alcohols such as ethanol, isopropyl alcohol, and ethylene glycol; acetone And ketones such as methyl ethyl ketone and cyclohexanone; ethers such as tetrahydrofuran, dimethoxyethane, diethyl ether and diisopropyl ether; esters such as ethyl acetate; nitriles such as acetonitrile; and amides such as dimethylformamide. Alternatively, a desired cleaning tool can be manufactured by dispersing (oil agent), impregnating a predetermined amount into a target cloth, mop, nonwoven fabric, paper, or the like, and then evaporating a diluting substance such as a solvent. Soaps, polyoxyethylene alkyl aryl ethers, polyoxyethylene fatty acid esters, fatty acid glycerides, sorbitan fatty acid esters, sulfuric acid esters of higher alcohols, alkyl allyl sulfonic acids so that the concentration of the drug is 0.1 to 50%. A wettable powder or emulsifier, together with an emulsifier or dispersant such as salt, is used to impregnate a predetermined amount of the target cloth, mop, nonwoven fabric, sheet, etc., then drain the water and heat dry to obtain a desired cleaning tool. Can be manufactured.

Cleaning tools composed of cloth, mop, nonwoven fabric, sheet, etc. are often treated with an oil agent for the purpose of enhancing the function of adsorbing and retaining dust (Japanese Patent Publication No. 63-67830, Japanese Patent Publication No. 5-10935, Japanese Patent Publication No. Hei 10-10935). 5-60925). In this case, an oil agent obtained by adding a non-cationic surfactant of 0.1 to 10% by weight to a mineral oil or a synthetic lubricating oil is dispersed in water, and an emulsion is adjusted to treat a cloth, a mop, a nonwoven fabric, a sheet, and the like. Has been done. Drugs having acaricidal activity and / or mite growth-inhibiting activity have many lipophilic substances and some have high vapor pressure. Therefore, 0.01% to 50% by weight of a drug is added to the above oil containing mineral oil or synthetic lubricating oil. (Preferably 0.05 wt% to 10 wt%), and the cleaning agent such as cloth, mop, nonwoven fabric, sheet, etc. is treated with an oil containing a chemical in the same manner as the above oil. As a result, it is possible to more efficiently perform the tick prevention treatment, and it is possible to maintain the mite growth inhibitory activity of the drug for a longer period of time. It is specified that a fragrance, a bactericide, and a fungicide are added to the above oil agent for use (Japanese Patent Publication No. 5-60925). The above oil agent is a novel composition.

On the other hand, in the case of a vacuum cleaner, a dust collection bag that suppresses the growth of mites can be manufactured by treating the dust collection bag with a chemical in the same manner as in the case of the cloth, mop, nonwoven fabric, paper, and the like.
The intended vacuum cleaner can be obtained by using this as a dust bag for a vacuum cleaner.

At the time of treatment of these chemicals, cellulose derivatives, vinyl resins, alkyd resins, urea resins,
Epoxy resin, polyester resin, urethane resin, silicon resin, acrylic resin, synthetic rubber, a film forming agent such as polyvinyl alcohol, a binder, and the like can also be added. Further, in the treatment of these chemicals, repellents and repellents for insects other than mites, rodent repellents, fungicides, fungicides, deodorants / deodorants, fragrances, coloring agents, and the like can be added.

(Mite growth inhibitory action) As is clear from the test examples described later (see Table 1), when the mop was used as a test sample and the mite growth retained on the surface and inside of the mop was observed over time, IF- 1000S, pyrethroids (including permethrin and synergists), and perfume ingredients (2
By treating the mop with a highly active agent such as (phenoxyethanol), the ticks do not survive almost completely after 2 weeks, and the ticks retained and adsorbed do not grow even after repeated use. it is conceivable that. On the other hand, when the mop was directly used (untreated with the oil agent) or only the oil agent containing no drug was treated (the oil agent treatment), the mites grew nearly three times after 4 weeks. After cleaning the room, remove the cleaning tool under conditions suitable for the growth of mites (temperature 20-
When left at 30 ° C. and 60-80% humidity), it is easy to imagine that the same result as the above occurs. By cleaning the room with such a cleaning tool, it is easy to imagine that live mites and mite allergens are spread.

[Table 1]

Hereinafter, the present invention will be described more specifically by using a mop as an example, but the present invention is not limited to these examples. (1) Test mite Dermatophagoides farinae H
ughes) used from Sumika Technos. As a breeding medium, an equal amount of powdered feed for laboratory animal breeding (manufactured by Oriental Yeast Kogyo; M) and dried powdered yeast Yebios (manufactured by Asahi Beer) were mixed and used.

(2) Test Mop The following test mop was used. A cotton mop manufactured by Duskin Co., Ltd. (250 piles / 100 cm 2, pile length 3 cm) not treated with an oil agent (oil agent untreated). According to the treatment method described in Japanese Patent Publication No. 5-10935, the same cotton mop was mixed with 99.8-94.0% of mineral oil,
-Sodium ethylhexylsulfosuccinate 0.1-2
%, Polyoxyethylene nonyl phenyl ether 0.1
Using an oil agent consisting of up to 4%, the amount of the oil agent is 1 to the fiber.
0 wt%, bath ratio 1:10, temperature 30 ° C., pH 7 for 5 minutes, 300 ppm of calcium chloride was added, salting out was performed for 5 minutes, and the treated mop was dehydrated with an electric washing machine.
A product prepared by drying at 2 ° C. for 2 hours and then air-drying for 1 day (oil treatment). The drug-treated sample was prepared as follows. 1% by weight of the antifungal agent IF-1000S (Nagase Sangyo) was added to the above oil agent, and a cotton mop was treated in the same manner as described above (IF-1000S). Permethrin (Sumitomo Chemical Co., Ltd.) (10 wt / vol%) and piperonyl butoxide (Wako Pure Chemical Industries) (50 wt / vol%) were dissolved in methyl ethyl ketone, and the solution was added to the above oil so as to be 1 wt%. The cotton mop was treated in the same manner as described above (pyrethroids). 2-Phenoxyethanol (Wako Pure Chemical Industries) was added to the above oil agent to a concentration of 3 wt%, and the cotton mop was treated in the same manner as described above (perfume component). All of these test mops also served as a stability test, and were left for one month at 25 ° C. and 70% humidity before being used for the test.

(3) Test method A mop piece (having about 60 piles) cut into 5 × 5 cm was fed 400 mg of feed containing Dermatophagoides farinae (average 15
(Including 0 mites). This was stored under conditions of 25 ° C. and a relative humidity of about 75%, and the number of live mites was counted after 2, 14, and 28 days. The number of live mites was counted by the following method. The test pieces (3 pieces per test section) in each test section were placed in 500 ml of water containing 0.5% kitchen detergent, and the mixture was inverted and stirred at 150 rpm for 1 minute. The test piece was left, and the aqueous solution was filtered with a filter paper to remove solids such as mites and other feeds. This operation was repeated three times, and the filtered live mites were counted under a stereoscopic microscope. The recovery rate of live mites in this operation was 80% as an average value of three recovery tests performed in advance. The results are shown in Table 1. However, the number of live mites (number of inoculated heads) on day 0 in Table 1 was a value obtained by multiplying the recovery rate by 80%.

[0021]

From the above results, it can be seen that the cleaning tool according to the present invention, which suppresses the growth of mites, particularly the cleaning tool treated with an agent having an acaricide activity and / or an activity of inhibiting mite growth, is excellent in mites. The present invention satisfies the object of the present invention in that a cleaning tool used for removing dust and dust in a room does not amplify and diffuse mite allergens, having a growth suppressing effect for a long period of time. The cleaning tool according to the present invention that suppresses the growth of mites is useful as a cleaning tool for maintaining a comfortable and healthy life.
