Abstract

Objective: This study was conducted to design the textile structure with mosquito repellent behavior using microencapsulated lemongrass extract.

Methods: Lemongrass oil extracted from Cymbopogon citratus by a hydro distillation process, which was used as core and gum acacia was used as wall material. About 10% W/V gum acacia was allowed to swell with hot water and stirred well with a temperature of 50Â°C. Further to this mixture 10 ml of lemongrass extract was mixed and stirred around 400 rpm for 15 minutes. Subsequent with this process, 20% V/V sodium sulfate was added then the stirrer speed was reduced 80 rpm, and then 5 ml of 17% formaldehyde was added along with this mixture. Finally, the microcapsules were obtained. Then, this lemongrass extract capsule mixture was coated on the fabric through pad dry cure method.

Results: Mosquito repellent study was carried out through the excito chamber method and assessed the mosquito repellency percentage. The maximum mosquito repellency percentage was obtained around 90%. Wash durability, abrasion resistance, air permeability, and bursting strength of the coated textiles were also studied. Scanning electron microscopy analysis and gas chromatography analysis were also performed for the samples.

Conclusion: It was proved that lemongrass microencapsulated textiles provide good resistance against mosquito bites and also concluded that this process is one of eco-friendly
