Thereby, a needlelike body having a jetting port is used therefor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of processing rugs such as futons, mattresses and tatami mats or bedding by post-processing so as to have antibacterial, deodorant, mildew-proof and insect-proof effects.

[0002]

2. Description of the Related Art Rugs such as futons, mattresses and tatami mats or bedding have been treated with antibacterial and antifungal treatments. The main method was to physically kill the fungi and insects by periodically heating and drying the processed material at high temperature, and in recent years, the antibacterial and antifungal agents have been retained during production. As a result, a treated product which has been subjected to antibacterial / antifungal treatment has been attracting attention. Here, the former method of physically dying must be performed frequently because the antibacterial and antifungal insect repellent effect is not persistent, and there is a drawback in that it is troublesome to move a rug or bedding. On the other hand, the latter method can be roughly divided into organic and inorganic antibacterial and antifungal agents, but those using organic agents are highly toxic There are restrictions, and as a result,
The problem is that the life of the effect is shortened. Therefore, it is common to use inorganic chemicals today, however, many rugs or bedding still have antibacterial / antifungal treatment from the time of manufacture, and the former It is the current situation that only the method of heat treatment described above is used, and it has been strongly desired that post-processing imparts an antibacterial / antifungal and insecticidal effect so as to provide sustainability.

[0003]

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned conventional problems, and by applying an inorganic antibacterial and antifungal agent as a post-treatment, the antibacterial, antifungal and insecticidal effect is obtained for a long period of time. Is to be maintained. As a result, the number of times of high temperature heating and sterilization treatment can be extremely reduced. Also, if it is installed in a conventional dryer, sterilization, antibacterial, antifungal, and insect repellent treatment can be performed during the same work, and the economic effect is very large.

[0004]

According to the present invention, a needle-shaped body having an injection port having a small hole at one end is inserted into a rug or bedding, and an inorganic antibacterial antibacterial agent is introduced from the injection port. It is characterized by spraying a mixture of a fungicide and insect repellent powder and an adhesive, and it is more preferable if it is carried out at the same time as the heat sterilization treatment. Antibacterial and antifungal insect repellent treatment is applied to the rug or bedding by post-processing.Therefore, a thin needle-shaped body is pierced into the rug or bedding-treated material, and a predetermined amount of antibacterial and antifungal is injected from the tip of the nozzle. The insect repellent is sprayed.

The antibacterial and antifungal insect repellent agent employed here must be a mixture of an inorganic antibacterial and antifungal insecticide and an adhesive. This is because the inorganic antibacterial and antifungal insecticide has a longer effect life and is easy to handle, and the inorganic antibacterial and antifungal insecticide used here is not particularly limited. , Antibacterial / antifungal insect-proof zeolite, antibacterial / antifungal insect-proof amorphous aluminosilicate, antibacterial / antifungal insect-proof intercalation compound, antibacterial / antifungal insect-proof soluble glass, and the like, preferably B ₂ O ₃ —SiO ₂ -Na ₂
O-based amorphous material with a B ₂ O ₃ elution rate of 42
5 to 600 μm, 1 to 30 as measured in water at 20 ° C.
It is preferably 0 mg / g / hr. This is because it was obtained from various experiments by the present inventor and can effectively kill mites. In addition, the adhesive may need to be mixed with the inorganic antibacterial and antifungal insecticide due to physical impact, because the cotton inside may easily separate and come out of the rug or bedding. There is. As long as this condition is satisfied, any general adhesive such as acrylic adhesive or urethane adhesive may be used. Furthermore, it is preferable to use particles having a particle size of 50 μm or less in the mixture because the injection conditions are better. According to various attempts in our experiments, the kneading amount of the antibacterial and antifungal insect repellent is 0.1 to 20 g / k for futons and mattresses.
For g and tatami, 1 to 200 g / m ² has been obtained.
The needle-shaped body is a mixture in which the above mixture is sprayed as fine mist powder inside the processed material under pressure, but the penetration force is weak and it can undergo physical impact to some extent, so it is a partial treatment. Therefore, needless to say, the processing can be performed over a wide range by using a plurality of lines.

On the other hand, heat sterilization and insecticidal treatment are generally performed at 60
It is usually for about 120 minutes to physically kill bacteria and insects. At this time, although the bacteria are completely eliminated, the rug or bedding tends to contain moisture due to moisture, and the growth of the bacteria is relatively early. Will happen to. Therefore, if it is used together with the above-mentioned post-treatment method at the same time, it provides an antibacterial and antifungal effect from a state free from fungi and insects, which is more preferable because the sustainability is prolonged. The conceivable method for this combined use is to achieve the above method by interlocking with or incorporating a commercial or domestic heating / drying machine.

EXAMPLES The present invention will be described in more detail with reference to examples. Inorganic antibacterial and antifungal insecticides were prepared according to Table 1, and the antibacterial and antifungal insecticides were pulverized to 40 μm or less.
Next, the urethane adhesive and the antibacterial and antifungal insect repellent are in a one-to-one relationship.
After mixing at a ratio of, the viscosity was lowered to such an extent that it could be sprayed with a solvent. This mixture was sprayed and fixed on the inside of a futon, mattress, or tatami by an antibacterial / antifungal insect-proofing method using needles. The respective conditions were as follows. For use in futon, antibacterial and antifungal agents, 5
Processed at a rate of 1 g of futon, and used as a mattress is an antibacterial / antifungal agent, 5 g / mattress 1
It was processed at a rate of 10 kg, and when used for tatami, an antibacterial and antifungal agent was processed at a rate of 10 g / m ² . After processing with the target amount of each, heating was performed at 60 ° C. for 120 minutes to sterilize and dry together with insecticide. The evaluations are shown in Tables 2 to 4 in comparison with the unprocessed products.

It was found that the futons, mattresses and tatami mats containing the antibacterial and antifungal agents have sufficiently suppressed the occurrence of mites during the period of use as compared with the untreated products. This also guarantees sustainability.

[0012]

[Effect] Since post-processing can give an antibacterial and antifungal insecticidal effect, it can maintain a sufficient effect for a long period of time, and if heat treatment is performed by incorporating with a dryer etc., heat sterilization, periodical insecticidal treatment can be performed. The number of times can be reduced as much as possible. In particular, if it is carried out at the same time as the dryer for business use, the burden of labor can be lightened and the economic effect is very large. Therefore,
As an antibacterial and antifungal insect repellent processing method that solves the conventional problems, it greatly contributes to the development of industry.
