An international team of researchers (USA – North Carolina State University, Germany) has developed a mathematical model for fabric barriers that resist bites from Aedes aegypti mosquitoes based on textile physical structure and no insecticides. The model was derived from mosquito morphometrics and analysis of mosquito biting behavior. Woven filter fabrics, precision polypropylene plates, and knitted fabrics were used for model validation. Based on the model predictions, prototype knitted textiles and garments were developed that prevented mosquito biting, and comfort testing showed the garments to possess superior thermophysiological properties. The fabrics provided a three-times greater bite resistance than the insecticide-treated cloth. The predictive model can be used to develop additional textiles in the future for garments…read more.
