ことが多くなってきている。(B) Problems to be Solved by the Prior Art and the Invention Conventionally, compressed naphthalene, camphor, and the like have been commonly used as insect repellents for clothing and the like. Recently, not only insect repellents but also deodorizers, dehydrating agents, and the like have been increasingly used for clothing.
この場合、防虫剤、脱臭剤及び脱水剤を各々共存させて
通用するわけであるが、防虫剤はそのまま若しくは穿孔

触し、各々の性能に悪影響を及ぼすという欠点があった
。例えば１、脱水剤が水を吸収して潮解し、防虫剤に付
着すると防虫性能がｔｉなわれるということがあった。In this case, an insect repellent, a deodorizing agent, and a dehydrating agent can all be used together, but the insect repellent is exposed to the outside because it is left as is or is housed in a perforated film. Therefore, it has the disadvantage that it comes into direct contact with other deodorizing agents and dehydrating agents, which adversely affects the performance of each. For example, 1. When a dehydrating agent absorbs water, deliquesces, and adheres to an insect repellent, the insect repellent performance may be diminished.
そこで、本発明は防虫剤が他の脱臭剤等と直接接触する
ことがないようにすることを目的としてなされたもので
ある。Therefore, the present invention was made with the object of preventing the insect repellent from coming into direct contact with other deodorizing agents.

ベンゼン、トルエン、キシレン等が用いられる。In the present invention, first, an aqueous solution in which a water-soluble polymer is dissolved in water and an organic solvent solution in which an aromatic insect repellent component is dissolved in an aromatic organic solvent are prepared. Examples of water-soluble polymers include polyvinyl alcohol, microcrystalline cellulose,
Gelatin, gum arabic, methylcellulose, carboxymethylcellulose, polyvinylpyrrolidone, etc. can be used alone or in combination. Aromatic insect repellent ingredients include naphthalene, paradichlorobenzene, hexachloro-
Conventionally known materials such as epoxy-octahydro-dimethanonaphthalene can be used. As aromatic organic solvents,
Benzene, toluene, xylene, etc. are used.

００μ程度のものを言う、また、液滴の粒子径は分散液
の攪拌の程度によって所望のものを得ることができる。When an organic solvent solution is dropped into an aqueous solution using a dropping funnel or the like, droplets of the organic solvent solution are dispersed in the aqueous solution. By stirring this dispersion and making the size of the droplets fine, a suspension in which the fine droplets are cloudy can be made. Note that fine droplets here have a particle size of 1 to 10
The particle size of the droplets can be adjusted to a desired size depending on the degree of agitation of the dispersion.

子膜の厚さが極めて薄いこと等が考えられる。The resulting suspension is atomized with a sprayer to create atomized droplets. The spray droplets obtained from this suspension are in the form of a fine droplet as a core surrounded by an aqueous solution. Hot air is then blown onto the spray droplets. Then,
The water and organic solvent in the spray droplets evaporate and a solid is obtained. One unit of this solid material is a so-called microcapsule, which has an insect repellent component as a core surrounded by a water-soluble polymer film. The water-soluble polymer membrane has countless pores. The reason for the presence of pores is that the membrane tends to become discontinuous because it dries in the dynamic state of spraying, and the sprayed droplets themselves are minute, so the thickness of the water-soluble polymer membrane is extremely thin. is possible.

障が生じる場合がある。The concentration of the water-soluble polymer in the aqueous solution used in the present invention is preferably about 0.5 to 10% by weight. If the concentration of the water-soluble polymer is less than 0.5% by weight, the insect repellent It becomes difficult to completely surround the agent components (there is a tendency to move), and if the amount exceeds 10% by weight, it may be difficult to spray the suspension.

degree is preferred. B5 degree of insect repellent ingredient is 10ffi amount%
If it is less than 60% by weight, the amount of insect repellent contained in the approximately spherical water-soluble polymer membrane tends to decrease, and if it exceeds 60% by weight, the insect repellent component may not be completely dissolved.

全に水溶性高分子膜で覆われない場合が生じる。In the suspension obtained by dropping the organic solvent solution into water/8 liquid, the amount of the organic solvent solution forming fine droplets is 5 to 5.
Approximately 3011% is preferable. If the amount of the organic solvent solution is less than 5% by weight, the yield of the insect repellent obtained will decrease and production efficiency will be poor, and if it exceeds 30% by weight, the insect repellent components will be completely covered with the water-soluble polymer film. There may be cases where this is not the case.

Therefore, even if it is used in combination with other deodorizing agents, dehydrating agents, etc., the insect repellent components do not come into direct contact with each other, so that insect repellent performance etc. are less likely to be impaired. For example, even if the dehydrating agent deliquesces and adheres to the insect repellent, it does not directly adhere to the insect repellent components, so the volatilization of insect repellent gas etc. is less likely to be impaired.
