Abstract:

Lavender essential oil has aromatherapy effects. It can be widely used to improve people’s health in the daily chemical, foodstuff, medical et.al. However, due to the strong volatility of lavender essential oil, its long-term use in life is limited. The microencapsulation method realizes the encapsulation of lavender essential oil, which reduces the influence of physical factors such as temperature and light on the essential oil from a microscopic perspective. β-cyclodextrin realizes the complexation with lavender essential oil from the molecular. Chitosan and Sodium Alginate can prepare microcapsules of different sizes by changing the reaction conditions. Textiles is a medium for fragrance, and nano-textile technology and multi-scale fiber mixing technology combine microcapsules with textiles. Long-lasting and stable release of essential oil on textiles can be achieved by adjusting the structure of micro- and nano-fibers, or using fiber or fabric finishing techniques, which forms a lasting and stable aroma effect in the living environment. Combined with the current research status at home and abroad, the preparation technology of lavender essential oil microcapsules and the construction method of aromatic textiles are expounded. The research direction and prospects are prospected, which is significance for broadening the application of lavender essential oil and developing textile products with aromatic functions.
