[0002]

2. Description of the Related Art Hitherto, various insect repellents having various specifications have been studied as insect repellents used for protecting textiles such as clothes from harmful insects. Some of them use a deodorant and a desiccant together.For example, activated alumina is used as a deodorant, and powdered dichlorobenzene is used as an insect repellent. There is known one related to the insect-proof deodorizing dry sheet enclosed in.

In such insect repellents containing dichlorobenzene, camphor, etc. as an active ingredient, sublimation of the active ingredient diffuses the odor of the insect repellent into the surrounding atmosphere. However, there was a problem that the desired effect was hardly obtained.

However, since a pyrethroid compound having almost no odor has been developed as an active ingredient of an insect repellent and the problems as described above have been solved, in recent years, an insect repellent and a deodorant have been used in combination with an insect repellent effect. Various studies have been made on removing the odor of the ambient atmosphere. For example, as one capable of exhibiting both the functions of deodorant deodorization and pest control at the same time, an insect deodorant deodorant sheet in which a deodorant deodorant composed of activated carbon, silica gel, etc. and a pyrethroid insect repellent is carried on a sheet-shaped substrate is known. ing.

However, the deodorizing agents such as activated carbon and silica gel have a drawback that even the volatilized insect repellent components are adsorbed because the deodorizing action is mainly based on physical adsorption. It is hard to say that both functions will be exerted at the same time, and at present the effective means to replace this has not been fully examined.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and an object thereof is to provide an insect repellent deodorant capable of exhibiting both insect repellent and deodorant functions at the same time. To do.
