Abstract

The invention relates to a method for preparing a borneol synthetic fiber anti-mosquito functional fabric. The method comprises the steps of picking fresh new sway borneol camphor leaves and branches with more than two tree years, cleaning the leaves and the branches, drying moisture, arranging the leaves and the branches in a sealing steam pressure tank, conducting cooking, collecting borneol crystals in the inner wall of a cooling tank, enabling the borneol crystals and nylon 66 particles or polyester chips to be fused and mixed to be in a liquid state, machining the liquid into a fiber through silk drawing or silk spraying, and enabling the fiber or the fiber and a nylon fiber or polyester filament yarn or real silk fiber to be machined into the anti-mosquito fabric in a knitted mode. The method can be widely used for producing civil anti-mosquito shirts, silk stockings, anti-mosquito silk fabrics, anti-mosquito clothes of soldiers in an army and outdoor workers, and has biocompatibility on a human body and anti-mosquito and insect-prevention durability.

Description

technical field [0001] The invention relates to a preparation method of an anti-mosquito functional fabric, in particular to a preparation method of a borneol synthetic fiber anti-mosquito functional fabric. Background technique [0002] The harassment and harm of mosquitoes to humans is worldwide and has a long history. There are many kinds of viral diseases transmitted by mosquitoes, especially the dengue fever virus caused by Aedes mosquito bites is extremely harmful to humans. It is an acute infectious disease with fast transmission and high incidence. In severe cases, meninges will appear. Inflammation, haemorrhage and shock, leading to death. It has been reported that Aedes mosquito eggs can survive for 200 years in desert drought conditions. However, there is no specific drug for dengue fever in the world, and there is no vaccine protection. Once dengue fever becomes popular, it will bring great harm to human life and health and social and economic development. In r...
