The aim of the study was to prepare insect repellent textiles by encapsulating citronella oil with ethyl cellulose shell using the coacervation method. The application methods of coating and printing were compared, showing that both methods were effective in repelling mosquitoes after multiple washing cycles. The study demonstrated that the developed product could be used as an alternative to existing products in the market for preventing mosquito-borne diseases.
The aim of this study was to prepare insect repellent textiles and compare the application methods. Bio-based insect repellent agent citronella oil was encapsulated with ethyl cellulose shell with coacervation method. Morphological assessment showed that capsules had smooth surfaces and their shape was spherical. The homogenous size distribution of the capsules was supported and the mean particle size of the optimum formulations was almost 50 mu m. Outdoor upholstery fabrics were treated with citronella capsules by coating and printing to compare the application methods. After application, the insecticide effects of the fabrics were investigated and compared with the impregnation method. Insecticide activity was evaluated against common house mosquitoes (Culex pipiens), with respect to cone bioassay of World Health Organization. Mosquitoes tended to stay away from treated fabrics, and mortality rates of mosquitos were noted as 72, 65 and 55% for printing, coating and impregnation, respectively, and the fabrics still showed repellency after five washing cycles. This study showed that the developed product might be used as an alternative to the other products in the market for avoiding mosquito-borne diseases and these results showed that capsules can be transferred by printing and coating processes when compared with the impregnation method.
