JP3483302B2 - Washable blood-sucking pest repellent for textiles - Google Patents

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blood-sucking insect repellent component which has a washing resistance and a long blood-sucking insect repellent effect even after being processed into natural and synthetic fibers. The present invention relates to a wash-resistant blood-sucking pest repellent for textiles, which can be maintained for a period of time. More specifically, N, N-diethyl-m-toluamide and a pyrethroid compound are used as a blood-sucking pest repellent component, and a cationic and / or amphoteric activator is used in combination with the N, N-diethyl-m-toluamide compound, so that the blood-sucking pest repellent component becomes a fiber. Of the blood sucking pest repellent component is suppressed even by washing, it has washing resistance, and the blood sucking pest repellent effect can be maintained for a long time, and further, as in nylon pantyhose Provided is a washing-resistant blood-sucking pest repellent for textiles which can sufficiently cope with thin textiles. 2. Description of the Related Art In order to prevent damage by mosquitoes, blackflies, brassicae, flies, and other insect pests that suck blood by direct biting from exposed parts of the human skin, dimethylphthalate and diethyl are applied directly to the skin. Phthalate, dibutyl phthalate, and the like have been used, but in recent years, N, N-diethyl-m-toluamide has been found to have even better efficacy as a repellent for blood-sucking pests, and has been widely used in general. However, this method of use generally applies these repellents directly to exposed skin. Therefore, there is a concern that the repellent may become uncomfortable on the skin due to the stickiness of the repellent, and that the used repellent may be absorbed into the body through the skin.The boiling point of the repellent is relatively low, so the effective time is very short, several hours. Thus, there is a major drawback that the coating must be performed many times in one operation. In addition, if the method of processing into textiles is a method of fixing with a resin binder or the like, it is good for general clothing, but if it is thin like pantyhose, the flexibility is impaired and sufficient washing resistance is obtained. Therefore, the improvement was desired. [0004] Diseases mediated by blood-sucking pests are very common worldwide. Areas under conditions where mosquitoes, a representative of the blood-sucking pests that cause this damage, occur are often found in undeveloped land near the equator. Its distribution has spread from Japan, Southeast Asia and the Indian Ocean to New Guinea, Australia, the South Pacific, China, Africa, the United States, and Brazil. For this reason, the United States is also spending enormous costs on countermeasures. Among the blood-sucking pests, mosquito-borne infectious diseases are the most common. For example, it is estimated that malaria and the like are still infected and brought back to those who traveled or traveled to Southeast Asia. In addition, a large number of people still suffer from yellow fever, dengue fever, various encephalitis, and filariasis. [0005] Common blood-sucking insects in Japan include mosquitoes, mites, fleas, and bed bugs indoors. On the other hand, in the outdoors, there are blackflies, yabuca, nukaka, flies and sand flies. These pests are also being reduced in urban areas as a result of significant environmental improvements, but are still prevalent in suburban and rural areas. Damage caused by blood-sucking pests includes infectious diseases from bites, discomfort, dermatitis, insect allergies,
Insomnia and the like. The species of mosquitoes include Culex pipiens, Culex pipiens, and Culex pipiens. The Aedes' group includes Aedes albopictus, which is a representative species of Aedes, and other species such as Aedes albopictus, Aedes albopictus, Aedes albopictus, and Sesazia aeruginosa. The main types of anopheles are the Anopheles and the Anopheles. It is presumed that mosquitoes approach humans not only because of the detection of carbon dioxide emitted by breathing, but also because of the odor of lower fatty acids such as lactic acid and caproic acid generated from the skin. On the other hand, blackflies are blood-sucking pests that are less familiar to those living in urban areas, but are often damaged when they leave the city for golfing, fishing or hiking. Buyhu is often attacked in the mountains in the evening. that too,
Damage concentrates on lower limbs. As such, women seem to be more vulnerable. When sucked by a blackfly, it can't stand the pruritus and scratches it. There are many types of blackflies, but the particularly aggressive ones are Aotsukimetogebuyu, Himeashishimadarabyu, Nipponyamabuyu and Obuyu. The present invention is directed to a fiber which is processed into natural and synthetic fiber products so as to reduce the damage caused by the blood-feeding insects as described above, and the treated blood-sucking insect repellent can withstand washing and maintain its efficacy for a long period of time. An object of the present invention is to provide a wash-resistant blood-sucking pest repellent for products. Means for Solving the Problems As a result of studying to solve the above problems, the present inventor has found that N, N-diethyl-m-toluamide and pyreth as components for repellent of blood-sucking insect pests. > Using a Lloyd compound, a cationic activator and / or
Alternatively, the present inventors have found that the use of an amphoteric activator provides a wash-resistant blood-sucking pest repellent for textiles which has washing resistance and can maintain the efficacy for a long period of time, and completed the present invention. That is, in the present invention, N, N-diethyl-m-toluamide and a pyrethroid compound are used as blood sucking insect repellent components, which are used in combination with a cationic activator and / or an amphoteric activator.
