Fabric treatments with β-Cyclodextrins (β-CD) have been studied for different applications as nanotechnologycal approaches to achieve functional textiles. In particular, repellents and insecticides have been incorporated in β-CD treated textiles to prolong their release. In this case, Citriodiol®, a naturally derived mosquito repellent, was incorporated to β-CD treated polyester (PET) nets. Two methods for citriodiol inclusion were studied; i) pipette dripping or ii) impregnation of fabric in a plastic bag, in order to increase the repellent activity of PET textile substrates. Release profiles were analyzed by gas chromatography and repellency was monitored by in vivo assays with Aedes aegypti mosquitoes. Long lasting and reloadable mosquito repellent nets could be achieved by treating PET knits with citriodiol/β-CD complexes.
