DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a particulate insect repellent utilizing waste materials, and more particularly to a particulate insect repellent for fibers, for example, wool. The present invention also relates to an insect repellent that can be widely used to prevent insects that harm wool products, and more particularly to a granular household insect repellent having a moisture-proof function.

[0002]

2. Description of the Related Art In order to prevent wool products from being damaged by insects, sublimable insect repellents such as camphor, naphthalene and paradichlorobenzene are used for storing wool products. These solid insect repellents have a peculiar odor, act as respiratory poisons against pests such as carp, iga, brown house moss, brown beetle, and brown beetle and have a repellent effect. In addition, synthetic pyrethroids, which are insecticidal components that have a contact toxic effect on these pests, have also been used since they are relatively harmless to warm-blooded animals. It is impregnated and used as a closet. This transpirable empensulin has no odor and can maintain its effect for a long time at a lower concentration than dichlorobenzene.

[0003]

However, among these insect repellents, solid sublimable insect repellents are used after being molded, and the persistence of the insect repellent effect depends on the hermeticity of the container used. Replenishment must be continually dependent, for example, sublimating in months. Evaporative empenthrin can be used for a relatively long period of time, but requires a carrier such as paper or nonwoven fabric for impregnation. Such a carrier needs to be adsorbed and is relatively flexible, so it is used in a plastic container, and the ratio of the price of the container and the like is increasing, which is problematic.

On the other hand, wood chips such as wood powder of hiba and hinoki are generated in a large amount in the lumbering process of hiba and hinoki. However, hinokitiol and hiba oil have insect repellent and antiseptic functions and are hard to rot, so that disposal is difficult. , that has been a problem are incinerated over the mama cost with little use.

[0005] The used office paper is broken by a shredder or the like to generate a large amount of paper waste, and a large amount of punch waste generated when punching the office paper is burned as it is at a high cost. Furthermore, in the disposable diaper industry, as the demand for disposable diapers increases, the amount of paper powder of waste materials generated in the disposable diaper manufacturing process is enormous, and is difficult to handle because it contains unused superabsorbent resin. It is rarely used, and as such, is disposed of by incineration at a high cost, which is a problem. SUMMARY OF THE INVENTION It is an object of the present invention to solve the problems of disposal of wood chips such as hiba wood and hinoki wood containing paper powder and hinokitiol or hiba oil, and the problems of conventional insect repellent materials.
