Description

[Detailed description of the invention] (Industrial application field) The present invention is applicable to humans and livestock outdoors and indoors.

This product is related to repellents that prevent pests such as mosquitoes, blackflies, horseflies, and insects that suck blood from pets, etc., and is applied to natural and synthetic fiber products used outdoors, especially in agriculture, forestry, sports, military equipment, etc. This invention relates to a method of processing a blood-sucking insect repellent/repellent that can be washed approximately 50 times.

(Prior art) Most of the methods conventionally used as repellents for blood-sucking pests involve applying the drug directly to the human skin, which has a short duration of effectiveness for controlling blood-sucking pests, and also has the disadvantage of causing discomfort on the skin. Furthermore, absorption of the drug through the skin is also a problem.

(Problem to be solved by the invention) There are many diseases transmitted by blood-sucking pests around the world, and there are many diseases that are important in terms of wide distribution, number of patients, and survival rate.For example, malaria transmitted by mosquitoes. , yellow fever, dengue fever, Japanese encephalitis, and phyciliasis are still the most important infectious diseases in tropical and subtropical regions today. Important human blood-sucking insects in Japan include mosquitoes, fleas, bedbugs, and ticks indoors. Outdoors, there are flies, mosquitoes, black flies, insects, and horseflies. Damages caused by these blood-sucking pests include bites, discomfort, dermatitis, insect allergies, and food contamination.

Damage caused by such blood-sucking insects has been greatly reduced in the district due to the construction of sewage systems and environmental improvements. Furthermore, the structure of houses has become airtight rather than open like in the past, and with the spread of screen doors, the damage caused by insects has been surprisingly reduced, and the need for mosquito nets has almost disappeared. On the other hand, however, the damage has not yet decreased in areas with ponds and trees, such as parks, and in rural areas or areas adjacent to rural areas. The damage caused by blood-sucking pests is not just blood-sucking. Female mosquitoes and blackflies need to suck blood in order to lay eggs. It is not only humans who suck blood, but also pets, livestock, wild animals, etc. The damage caused by blood-sucking mosquitoes is not only the bites, but also the inability to sleep at night, which reduces the egg-laying rate of chickens, and the milk production of dairy cows, which causes great physical exhaustion. An important aspect of the damage caused by bloodsucking is that it acts as a vector for infectious diseases. Although there are many types of mosquitoes, it is said that each type of mosquito harbors only one type of pathogen. The places where these large numbers of mosquitoes lay eggs are limited to areas with water. Since these water sources exist everywhere, it must be said that it is extremely difficult to prevent the occurrence of mosquitoes.

Well-known types of mosquitoes include Culex pipiens, Culex pipiens, Aedes albopictus, Aedes albopictus, Aedes aedes, and Aedes albopictus.

Mosquitoes lay eggs in ponds, swamps, rice fields, and other wetlands, as well as in puddles that form every time it rains, so it is not easy to completely eradicate mosquitoes. This is because it takes about 20 days for the mosquitoes to lay eggs.

Common methods for eradicating mosquitoes include spraying insecticides, smoking,
Such as mosquito coils. In addition, there is a method of controlling blood-sucking insects by applying a repellent to the affected areas of the skin, albeit temporarily, for people working in agriculture, forests, fishing, playing golf, etc.

Blood-sucking insects called blackflies are not well known to those who live in the area, but they often live in mountainous regions with beautiful water. Blackflies attack people and animals violently in large numbers and mainly suck blood from the lower limbs. Golf courses and tourist spots were also severely damaged, to the extent that it was impossible to stand still on the edges at dusk.

If the blood is sucked, the result will be only redness and a rash, but serious injuries may occur due to bacterial infection. There are quite a number of types of blackflies, but they occur frequently in our country.♂ ・Those that are particularly aggressive towards people are blackflies, blackflies, blackflies, Japanese blackflies, Japanese blackflies, and other types of blackflies that are found in mountain streams. It often occurs in streams and irrigation canals. To get rid of black flies, you can kill them by injecting insecticides into the area where the larvae are occurring, or by applying repellents such as insect repellents directly to the skin.
Although it has been shown to be effective to some extent, there are problems with the duration of efficacy and discomfort on the skin.

In this way, mosquitoes in the outdoors are mainly Aedes mosquitoes, while in the house they are Culex mosquitoes. In addition, Southeast Asia and other areas
Even in undeveloped areas, the damage caused cannot be taken lightly.

(Means for Solving the Problems) The present invention has an excellent repellent effect against mosquitoes and blackflies for the purpose of preventing mosquitoes and blackflies from sucking blood, preventing transmission of pathogenic bacteria, and preventing scratches caused by itching caused by sucking blood. 2,
The use of 2-dimethyl-3-(2-methylpropenyl)cyclopropanecarboxylic acid (-3-phenoxyphenyl)methyl ester (hereinafter referred to as 1;'-milphenothrin) and further the potency enhancer =,

becomes 0. In addition, by treating textile products with a special modified polyester aqueous dispersion that can obtain functionality by heat treatment and a drug containing the compound of the present invention, phenothrin alone or in combination with an efficacy enhancer, and then heat-treating the product, it is polymerized together with phenothrin or on the fiber surface. Therefore, even after washing about 50 times, about 80% of the repellency remains due to the decrease in water elution, and it is clear that this effect is obtained by the resin component used in combination. The self-crosslinking resin may be used alone, but by combining it with a catalyst, the temperature and reaction time can be made more favorable.

Heat treatment is required at a polymerization temperature of 80 to 130°C and for a time of 1 to 5 minutes. The crosslinking agent used in combination with the repellent is a polyester aqueous dispersion, alkylene resin, guanamine resin, polyurethane resin, melamine resin, urea resin, etc. that exhibits functionality by heat treatment, and the resin component is 3 to 5% of the repellent component. %use. The squeezing rate during chemical treatment is 220-50% for thin fabrics, and 70-80% for thick fabrics, cotton, linen, etc. Therefore, the concentration of the chemical can be adjusted depending on the squeezing rate, and the concentration is 0.01 to 0.01 m2/m2 of liphettrin. 0゜5g
, preferably 0.05g to 0.3g.

In addition, by adding the potency enhancer in an amount 2 to 5 times that of phenothrin, the amount of phenothrin used can be reduced to 0.005 to 0.005.
．． 1 g'/m'', preferably 0.01-0.05 g/m
m'' alone, it is possible to reduce the amount considerably. This reduction is the safety factor of the drug.

This is important because it will reduce the amount. The washing resistance effect is approximately 80% or more even after 50 washes using a household washing machine and using any detergent such as powder detergent, liquid detergent, concentrated detergent, or enzyme detergent. Residues of the drug were detected by gas chromatography. It has also been demonstrated that it remains sufficiently effective in repelling mosquitoes. This washability has been given to natural fibers such as cotton and linen, as well as polyacrylic, polyester, polyurethane, vinylon, and polyvinyl chloride.

■For synthetic fiber soles such as polypropylene and polyvinylidene, it is thought that when used in combination with self-crosslinking thermosetting resins, they harden on the fiber surface and remain effective because they do not dissolve into water when washed. It will be done.

The present invention processes a blood-sucking insect repellent onto the surface of fibers, and the fiber products include general clothing, pantyhose, socks, gloves, work clothes, hats, towels, camping supplies such as tents, mountain climbing supplies, Fishing clothing, golf clothing or farming.

It can be used to repel blood-sucking insects such as mosquitoes, blackflies, horseflies, and black flies on a wide range of outdoor clothing, including forestry-related supplies and military supplies. The drug can be prepared by dissolving phenothrin alone or as a potency enhancer by dissolving piveronyl butoxide in a solvent such as xylene, ethanol, acetone, glycol or glycol alkyl ether, and then adding a nonionic surfactant, anion, or surfactant. It is used in an amount of 5 to 30%, preferably 10 to 20%, based on the self-crosslinking resin repellent. In addition, antioxidants, ultraviolet absorbers, antibacterial agents, antifungal agents, deodorants, and the like can also be used as stabilizers.

The details will be explained below using examples.
