An attempt was carried out to suggest a nano-sized agent for durable fragrant finishing of fabrics. By adopting emulsification-diffusion method, we could prepare polystyrene (PS) aromatic nanoparticles (ANP) with lavender oil (LO) in core. Effects of process parameters on mean particle size and its distribution of PS-ANPs were also examined. With controlled preparative condition, we could obtain PS-ANPs of diameters ranging 200 to 400 nm with narrow distribution. PS-ANPs were coated with poly(vinyl alcohol) layer to restrict the diffusion of LO from PS-ANPs. Sustained release properties of PS-ANPs were also evaluated.
