Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a granular insect repellent material using waste, and more particularly to a granular insect repellent material for fibers such as wool. The present invention also relates to a granular insect repellent material that can be widely used to prevent insects that damage wool products such as woolen fabrics, and more particularly to household granular insect repellent material having a moisture-proof function.

[0002]

2. Description of the Related Art In order to prevent the woolen fabric from being damaged by insects, the woolen fabric is stored, for example, with camphor, naphthalene,
Sublimable insect repellents such as paradichlorobenzene are used. These insect repellents have a characteristic odor,
It acts as a respiratory poison against pests such as squid, brown house moss, beetle beetle, and beetle beetle, and has a repellent effect. In addition, against these pests, synthetic pyrethroids, which are insecticidal components having a contact poisoning effect, are also used because they are relatively harmless to warm-blooded animals, and transpirational empensulin is used for paper and nonwoven fabrics. It is impregnated and used as a closet. This transpirationable empensulin has no odor and can maintain its effect for a long time at a low concentration as compared with dichlorobenzene.

[0003]

However, among these insect repellents, sublimable insect repellents are used by molding, but the persistence of the insect repellent effect depends on the sealing property of the container, for example, within several months. In order to be completely sublimated, replenishment must be done constantly. Evaporable empensulin can be used for a relatively long period of time, but it is necessary to use a carrier such as paper or nonwoven fabric for impregnation. Since such a carrier needs to be adsorbable and is relatively flexible, it is used in a plastic container, and the price of the container or the like occupies a large proportion, which is a problem.

On the other hand, with the increase in demand for coffee beverages such as canned coffee and instant coffee and beverages such as canned tea and instant tea, the extraction residue obtained by extracting these beverages, such as coffee grounds and tea leaves, is enormous. It is a huge problem in the beverage industry, such as coffee beverages, because the amount thereof is large and the treatment thereof is very expensive. In particular, since the coffee extract extract residue contains a large amount of fat, it is incinerated exclusively and is a problem. The amount of paper scraps broken by shredders of used office papers and punch scraps generated when perforating office papers is enormous, and these paper scraps are incinerated at the expense of the sacrifice.

Further, in the disposable diaper industry, as the demand for disposable diapers has increased, the amount of waste paper powder generated in the process for producing disposable diapers has increased enormously and the unused super absorbent resin is contained. It is awkward to handle, is rarely used, and is discarded by incinerating it at a cost.
It is a problem. In addition, a large amount of wood chips such as wood powder of Hiba wood are generated in the process of sawing Hiba, but because Hiba oil has an insect repellent and antiseptic function and is hard to rot, it is difficult to dispose of it, and it is rarely used and the cost of it is reduced. It has been incinerated and is a problem. It is an object of the present invention to solve the problems associated with the disposal of coffee extract residue, tea leaves, paper powder and / or wood chips of hiba wood, and the problems associated with conventional insect repellent materials.
