Application of Essential Oil on Silk Through Microencapsulation with β-Cyclodextrin to Achieve Fragrance Finish

Beta-cyclodextrin and lavender essential oil are applied to silk fabric following the microencapsulation technique. The olfactometric analysis is done to assess the presence and intensity of the odour of lavender essential oil after 30 days of storage and after 10 home laundering. The stiffness of the controlled and treated silk fabrics under different specified conditions is tested, and findings reveal a slight increase in stiffness for treated silk fabric that may be due to the deposition of beta-cyclodextrin during application. The infrared spectroscopic analysis of the beta-cyclodextrin, degummed silk fabric, and degummed silk fabric treated with beta-cyclodextrin and essential oil is also reported. Gas Chromatography analysis reveals the presence of essential oil in the treated silk fabric after 10 wash cycles. The scanning electron microscope identifies the surface morphology that appears to be irregularly shaped particles or clusters due to aggregation.
