Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides Li! The present invention relates to bedding that is characterized by being insect repellent and insecticidal, using a pyrethroid insecticide held in a holder or other holding body.

Here, bedding refers to pillows, bedding, such as quilts, mattresses, manotresses, beds, etc.

Since ancient times, buckwheat hulls, feathers, cotton, cotton, M1 shells, etc. have been used as fillers for S ingredients, but since they are natural products, there is inevitably a risk that various small insects, including pests and non-pests, may be mixed in. high,
In addition, since almost no chemical treatment is used before or after it is manufactured into bedding, small insects that enter the shell must be exposed to germs, grains, etc. that remain in the shell, or under a good environment with feathers, cotton, and attached materials. The insects turn into larvae and adults, which not only eat away at the filling material, but also the material of the bag body, and may emerge from the outside of the bedding.

In addition, even if chemical or electric insecticide treatment is applied, only the larvae and adults will die because the treatment is temporary, but the eggs, which are highly resistant to drugs, will survive and eventually become larvae and adults.
Due to the poor diffusivity of the drug, only a small portion of the drug died, and the one area where it was not able to diffuse showed no medicinal efficacy, indicating that the drug was not sufficiently effective. Furthermore, after 6 months to a year of bedding production, surviving pests or pests invade from outside and often eat away at the pillow bag, leading to the emergence of bedding that has been treated with more effective insect repellent and insecticidal treatments. It was strongly desired.

As a result of extensive research in view of these current circumstances, the present invention has been developed. That is, by retaining the pyrethroid insecticide in natural products such as buckwheat hulls, m-hulls, feathers, cotton, cotton, and cereal straw used as fillers for bedding, or by retaining the insecticide in other carriers, They discovered that by mixing this with filler for bedding, the entire bedding could be made insect-proof and insecticidal, and this led to the completion of the present invention.

Methods for retaining pyrethroid insecticides in buckwheat husks, feathers, cotton, cotton, rice husks, etc. used as fillers for bedding include the use of raw insecticides or liquids in which the insecticides are dissolved, dispersed, emulsified, or suspended. For example, by directly treating the material, for example, by impregnating, spraying, or dropping it, or by impregnating, spraying, or dropping a similar raw material or liquid onto the holding material, or by mixing it with the holding material and forming it into a reed shape, etc., as a filler. It can be carried out arbitrarily, such as mixing and holding with.

In addition, as a carrier, a wide variety of materials that can hold drugs can be used, but examples include paper, fabric, nonwoven fabric, wood, plastic, rubber, threads, powders, grains of inorganic materials, etc.
Plates, foams or sheets, or buckwheat husks, H1 husks, feathers, cotton, X-cotton, synthetic fiber cotton, wool, and natural meal, such as corn meal, which are used as fillers.
Examples include grain straw.

Furthermore, any pyrethroid insecticide that imparts insect repellent and insecticidal effects can be used, but examples include the generic names allethrin, tetramethrin, resmethrin, flamethrin, phenothrin, permethrin, cypermethrin, decamerin, fenvalerate, and 7-enpropas. phosphorus, tefrethrin, empenthrin, pyrethrin,'

These Vires[1-ide thread insecticides can be used alone or in combination of two or more kinds, and the preferred usage rate is 10 Iv-IG'- per 7 bedding per person.

If it is less than 1 (iq), the efficacy will be insufficient, and if it is more than 1 g, the efficacy will be sufficient, but the amount will be more than necessary, and it will be wasteful in terms of cost. It is also possible to add fungicides, insect repellents, mulch, etc., but the above treatment is extremely safe as it does not have any stickiness or coloration compared to conventional insect repellents such as Balajichlorobenzene. EXAMPLES The present invention will now be described with reference to Examples.

Examples 1 to 5 During the pillow manufacturing process, after removing dust and fine buckwheat shell pieces in steps 7 to A, when the buckwheat shells were sent to the conveyor belt y, the following chemical solution was dropped into the buckwheat shells according to the amount and treated with cotton. Fill the bag with 35kQ. Furthermore, it was placed in an outer bag to obtain 7 liters of insecticidal pillow of the present invention.

A: Bis(λ & 34-tetrachlorq-pyl) ether Examples 6 to 8 After filling 3 tons of buckwheat shells into a bag using a Makuraten-zukuri tokoi, a predetermined number of chemical solution-treated holders prepared by the following method were added. After additionally inserting or adding it and dispersing it uniformly, it is sutured, and then the outer bag e
An insect repellent/insecticidal pillow according to the present invention was obtained.

Lorbini N)-C/cI Clopan-1-Carbo Φ/Rate Example In the production of feather quilts, a predetermined amount of chemical solution is sprayed from the upper part of the belt during conveyance after the waterfowl feather cleaning process. 3 kq of the product was processed into a down comforter treated with insect repellents and insecticides according to the present invention.

Test Example Each filler material 5009 was taken out from the pillow and quilt shown in the above example and placed in a polyethylene bag.

Among these, 100 larvae and 100 adults were released and left in a dark place at 25℃ for 2 weeks, then the number of deaths was counted and insect control was carried out.
The insecticidal effect was determined.

A similar test was conducted using buckwheat hulls and feathers that were not treated with chemicals as blanks. The results are shown in the table below.

As described above, drug-treated buckwheat hulls and feathers showed sufficient efficacy.

Test Example 2 Using the pillows and comforters shown in the above WM example, a test was conducted to determine whether or not pests had invaded from the outside. That is, in the case of a pillow, it is 90 ma.
sh Make a nylon bag just big enough to fit the pillow in, and then put the pillow in it.

Next, 20 larvae and 20 adult sawfly beetles were placed between a nylon goose and a pillow and left in a dark place at 25°C for one month. Afterwards, we observed whether the larvae and adults were alive or dead, and whether they had entered the pillow.
The insect repellent and insecticidal effects were determined.

In the case of a futon, take out the feathers equivalent to 20 x 20 x 7 cm and place them in a 30 x 30 (m) futon bag.
5 cM) and a strain-like test was performed. A similar test was conducted using a drug-free pillow and feathers as blanks.

The results are shown in the table below.

Two series of results are shown.

As mentioned above, drug treatment pillow 1. Fudan C showed sufficient insect repellent and insecticidal efficacy.
