Problems solved by technology

However, most of these mosquito nets use drugs to directly soak the mosquito nets or directly mix insecticidal drugs with polyolefins. Although the prepared mosquito nets also have certain insecticidal effects, the drug effects are difficult to last, and they are not washable, and the service life is also short. Relatively short, does not have long-term insecticidal effect

Abstract

The present invention relates to a functional health and epidemic prevention fiber and a manufacturing method thereof. The fiber is manufactured by pesticide master batch with microcapsule structure and polyolefin. The manufacturing method comprises three steps of master batch manufacturing, drawn wire extruding and finished product manufacturing. The fiber of the invention is manufactured to various functional health and epidemic mosquito nets or other mosquito-preventing worm-expelling devices. The problems of inferior durability, inferior washing resistance, non-stop immersion requirement in using, etc. are effectively settled. Furthermore the functional health and epidemic prevention fiber and manufacturing method have the advantages of reduced cost for expelling worm, increased using life of worm-proof and worm-expelling device, excellent worm disinfestation effect, effective prevention of disease propagation, and obtainment of epidemic prevention.

Description

technical field [0001] The invention relates to a fiber and a production method thereof, in particular to a functional hygienic and anti-epidemic fiber and a production method thereof. Background technique [0002] Mosquitoes are vectors of many diseases. In order to suppress the spread of mosquitoes to diseases, mosquito nets with mosquito repellent effect have been studied at home and abroad, and certain results have been obtained. However, most of these mosquito nets use drugs to directly soak the mosquito nets or directly mix insecticidal drugs with polyolefins. Although the prepared mosquito nets also have certain insecticidal effects, the drug effects are difficult to last, and they are not washable, and the service life is also short. It is relatively short and does not have long-term insecticidal effect. In addition to increasing the dosage of pesticides, it is necessary to find more effective and alternative pesticides or other solutions. Contents of the inventi...
