Preparation method of plant-source long-acting mosquito-repellent composite functional filament

Abstract

The invention provides a preparation method of a plant-source long-acting mosquito-repelling composite functional filament. The preparation method comprises the steps of preparation of plant-source mosquito-repelling components, preparation of cellulose nano-porous aerogel, modification, preparation of plant-source mosquito-repelling functional master batches and spinning. SiO2 is embedded into the cellulose nano-porous aerogel, the porous structure of the cellulose nano-porous aerogel is supported, the cellulose nano-porous aerogel is not prone to collapse, the cellulose nano-porous aerogel can be soaked in a plant source mosquito repelling component solution again to be recycled after being washed for multiple times, long-acting mosquito repelling is achieved, and compared with a traditional mosquito repelling mode, the method is more environmentally friendly. After being woven into a fabric, the plant-source long-acting mosquito-repelling composite-function filament can be washed for more than 50 times and can be continuously recycled by soaking and adsorbing mosquito-repelling essential oil, odor emitted by the fabric can purify air and drive mosquitoes, a human body is effectively prevented from being bitten by the mosquitoes, and the fabric has a long-acting mosquito-repelling function. Meanwhile, the human body does not have any uncomfortable phenomena such as allergy.

Description

technical field [0001] The invention relates to the field of functional textiles, in particular to a method for preparing a plant-derived long-acting mosquito-repelling composite functional filament. Background technique [0002] Mosquitoes not only suck blood but also spread many diseases, such as malaria, Japanese encephalitis, and dengue fever, which pose a threat to human health, especially those who work outdoors, such as border guards, firefighters, farmers, etc. Suffering from mosquito infestation while working in the field is unspeakable. However, the traditional mosquito repellent methods have short action time, limited use scenarios and high cost, such as mosquito repellent water, electric mosquito swatters, mosquito coils, etc. These traditional mosquito repellent products can only be used once and cannot be reused. Mosquito products are all made of chemicals. While repelling mosquitoes, they will also have a certain impact on human health, especially children wi...
