DEVELOPMENT OF MOSQUITO REPELLENT TEXTILES USING CHRYSANTHEMUM OIL NANO EMULSION

This study is carried out for the development of mosquito repellent fabrics using chrysanthemum oil nano emulsion. The nano emulsion was synthesized using high speed homogeniser. The particle size was analysed using dynamic laser diffraction particle size analyser. Mosquito repellent textiles were achieved by treating nylon net fabrics with this nano emulsion using Layer by Layer technique. The finished fabrics were further analyzed for their mosquito repellent activity using modified WHO excito repellency test and mosquito mortality using WHO cone test. The treated fabrics showed 100% mosquito repellent efficiency and 90% mortality rate and retained their activity until 25 washes. SEM analysis of the treated and washed samples was also done. These types of textiles can protect the human beings from the bite of mosquitoes and there by promising safety from the mosquito borne diseases that include malaria and dengue fever.
