Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation method of plant source slow-release anti-mosquito functional pure cotton fabric, to solve the existing mosquito repellent method proposed in the above-mentioned background technology, which mainly uses chemically synthesized insecticides to repel mosquitoes. Mosquito repellents are likely to cause environmental pollution, which is not conducive to the existing environmental protection principles. At the same time, chemically synthesized insecticides are also likely to cause harm to the human body.

Abstract

The invention relates to a preparation method of plant-source slow-release anti-mosquito functional pure cotton fabric. The preparation method comprises the following steps: a, extracting and preparing effective anti-mosquito components, b, preparing an ethylenediamine aqueous solution with the concentration of 2%, gradually adding a dispersed phase into a continuous phase at a certain rotating speed, adjusting to the highest stirring speed after dropwise adding is completed, obtaining a stable o / w emulsion after 10-20 minutes, slowly adding the prepared ethylenediamine aqueous solution with the concentration of 2% into the o / w emulsion, stirring for 0.5-1 hour to obtain a mint / kaempferia galanga oil / eucalyptus camaldulensis microcapsule solution, and freeze-drying the anti-mosquito microcapsule solution for 72-96 hours to obtain the microcapsule powder. The preparation method of the plant-source slow-release anti-mosquito functional pure cotton fabric has the beneficial effects that the technology that trace substances are wrapped in a film formed by a natural or synthetic polymer is utilized, so that a strong repelling effect is achieved, the anti-mosquito rating is grade A, the environment is not polluted when the mode is used for repelling mosquitoes, and most of the materials are processed from natural materials and do not cause harm to human bodies.

Description

technical field [0001] The invention relates to the technical field of pure cotton fabrics, in particular to a preparation method of plant source slow-release mosquito-proof functional pure cotton fabrics. Background technique [0002] The bites of mosquitoes have caused serious disturbance to people's lives, and many diseases are transmitted by mosquitoes, such as malaria, dengue fever, yellow fever, filariasis, etc. In Asia, Africa and America, people who die from malaria every year due to mosquito bites The number of people exceeds 1 million, so the work of mosquito control is very important. Among them, pure cotton fabric is a kind of material commonly used in our life, so it is a better anti-mosquito method to make pure cotton fabric have anti-mosquito function. [0003] Existing mosquito repellent methods mainly use chemically synthesized insecticides to repel mosquitoes. This kind of mosquito repellent method is prone to environmental pollution, which is not conducive...
