Controlled-release mosquito expelling line mesh

Abstract

The invention relates to a line mesh with efficacy on expelling mosquito. Fibre lines inhale insecticidal or helminthic components to manufacture helminthic fibre lines under the condition of supercritical carbon dioxide; the helminthic fibre lines are separately arranged or interweaved with common lines to form the line mesh. Clothes made from the line mesh can be conveniently used for expelling the mosquito from contacting and biting a human body. A portiere made from the line mesh is applied to a room; and when a door is opened, the mosquito expelling efficacy of the line mesh can expel the mosquito from entering the room. A curtain made from the line mesh is applied to the room; even if the periphery of the curtain is remained with gap, and the mosquito expelling efficacy of the line mesh can still expel the mosquito from entering the room, so that the mosquito expelling line mesh with the mosquito expelling function can replace a mothproof window screen, can be used for decorating and beautifying the room and can also achieve the positive mothproof function. The line mesh containing the insecticidal or helminthic components can prevent the mosquito from biting the human body from a positive perspective so as to reduce the use of spraying or fumigating an insecticide indoors and have very important significance on protecting human health; and with the properties of controlled release and convenient use, the technology has very good application prospect.

Description

technical field [0001] The patent of the invention relates to a household item, in particular to a wire net for repelling mosquitoes, which belongs to the field of environmental sanitation. Background technique [0002] Mosquitoes not only cause skin itching and swelling through bites, but also transmit diseases such as encephalitis and malaria. At present, the living room is generally blocked by mosquitoes outside the window or in front of the door by installing an insect-proof gauze. Even so, mosquitoes can still enter the room when opening the door or through the gaps in the insect-proof screens. Therefore, although many houses have installed insect-proof screens, they still need to spray or fumigate insecticides to drive away indoor mosquitoes, or rely on mosquito nets to block mosquitoes from the human body to protect them. The human body is immune to mosquito bites. [0003] US Patent No. 7,152,809 applies for placing insecticide in a device. When the device is heate...

Problems solved by technology

U.S. Patent No. 7,243,375 has reported that insect repellant or insecticide is sprayed on a kind of net, and the net that has sprayed insect repellent or insecticide is woven into the ornaments of clothes or brim cuffs and other positions to make mosquitoes reluctant to approach human body, However, the net sprayed with insecticide cannot be washed, because the insect repellent or insecticide is sprayed on the surface of the net, and it is difficult to continuously exert the insect repellent effect

[0004] Chinese patent 03118798.6 reports that insecticide is sprayed onto the plastic of curtains to repel mosquitoes, which is similar to the principle adopted in US patent 7,243,375, and its repellent effect can only last for half a year

The process employed is not conducive to heat-sensitive insecticidal or repellent ingredients
