摘要
采用β-环糊精为壁材原料对薰衣草、迷迭香、檀香等香精进行包结络合,可以形成具有缓释性能的香精微胶囊。由于β-环糊精对人体无任何副作用且具有生态环保性,因此该香精微胶囊用于香味纺织品具有独特的安全性。UV-M图像分析系统和电镜观察结果表明,包合物微观形态存在菱形晶体和针状晶体。通过红外光谱确定了包合物的形成,并从热力学和溶解度方面分析了香精微胶囊的形成过程。
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-cyclodextfin 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.
