Problems solved by technology

It can be seen from the above-mentioned prior art that at present, there is a method of composite spinning, adding natural insect repellent or synthetic insect repellent as raw material to the fiber to prepare mosquito repellent fiber, and then preparing to form a fabric, as a carrier Most of the fibers are chemical polymer materials, and the moisture absorption and moisture dissipation and air permeability of the prepared fabrics are difficult to guarantee, and they cannot have good thermal and humidity comfort

Abstract

The invention provides a method for preparing a long-acting mosquito-repellent thermal-moisture comfortable hemp fabric. The method comprises the steps of washing fresh eucalyptus leaves produced in Yunnan Pu er county, mint and chamomile, placing the fresh eucalyptus leaves produced in Yunnan Pu er county, mint and chamomile at a shade place, airing the raw materials to be half-dry, cutting up and placing the half-dry eucalyptus leaves, mint and chamomile into a solution and boiling the solution, performing filtration and concentration, adding clove oil to obtain mosquito-repellent plant extract; steeping the China-hemp regenerated fiber in the mosquito-repellent plant extract, and performing two-steeping two-rolling processing to obtain regenerated cellulose fiber; taking blended yarn formed by China-hemp and long-staple cotton fiber composite spinning as warp, taking the regenerated cellulose fiber as weft, adopting through hole weave for a woven fabric structure, and forming the long-acting mosquito-repellent thermal-moisture comfortable hemp fabric by weaving through a circular machine. The prepared hemp fabric is green, environmentally friendly, comfortable, breathable, safe, repellent to mosquitoes, effective for a long time, and particularly suitable for making summer clothes.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a long-acting mosquito-repelling heat-humid and comfortable linen fabric and a preparation method thereof. Background technique [0002] In the hot summer, the hot and humid weather makes people feel depressed and irritable, and the hot and humid weather especially promotes the breeding of mosquitoes. The combination of the two causes great troubles to people's work and life. In recent years, with the continuous emergence of new technologies for textile materials, the functionality of textiles has also been rapidly developed, and mosquito repellent textiles have also emerged as the times require. At present, most mosquito repellent textiles are finished by attaching mosquito repellent or insecticide microcapsules to the surface of the fiber through adhesives and other additives, so that the surface of the textile forms a layer that is not easily soluble in w...
