Abstract: β-cyclodextrin molecules can form complexes with fragrance oils such as lavender,rosemary,and santalum to obtain fragrance microcapsule which possesses of the property of controlling fragrance-release rate.Since β-cyclodextrin has no any side effect to the human body and is environmentally friendly,its fragrance microcapsule can impart fragrance to textile and is safe.The micro morphology of microcapsule was rhombus and pin crystals observed by UV-M optical microscope and SEM.The mechanism of inclusion preparation was proved by IR.Meanwhile,the forming process of fragrance microcapsule was analyzed from the viewpoint of thermodynamics and solution degree.
