摘要：
Disclosed is an insect repellant fabric and a method for preparing the same, wherein, the method for preparing the insect repellant comprises the following steps: making a fabric composed of a lining layer made of natural fibers, an outshell layer made of synthetic fiber multifilaments, and a lapping layer made of polypropylene or polyethylene fiber monofilaments, and both the lining layer and the outshell layer are made as a mesh structure dipping the prepared fabric into an exhaust dyeing solution and being dyed for 10 to 120 minutes at a temperature of 60 to 105°C water rinsing, centrifuge drying and setting. Wherein, the exhaust dyeing solution is an aqueous solution containing emulsifiable concentrate, the emulsifiable concentrate is a mixture of pyrethroids and an alcohol-ether solvent in a mass ratio of 1:5 to 1:20 the mass ratio of the fabric to the exhaust dyeing solution is 1:7 to 1:20, and the amount of the emulsifiable solution is 5 to 10% based on the mass of the fabric. The method of the present invention has advantages such as a short processing flow, easy operation and low dosage of pyrethroids. In the method of the present invention, pesticides such as pyrethoroids are applied to the fabric by using exhaust dyeing process, which has a low requirement for the property and quality of the fibers. And the fabric prepared by using the method of the present invention shows good air permeability, strong defense function for insect invasion and permanent insect repellant effect.
