Encapsulation is the best method to protect the plant extracts against volatility and instability in the presence of air, light, moisture and high temperatures. Nevertheless, application of encapsulated plant extracts on the textiles requires a low-temperature and high rate processing to avoid from breaking or destroying of capsules. The present paper represents application of nanocapsules prepared by ultrasound irradiation assisted W/O/W microemulsion method on the cotton fabric through UV curing method. The surface and structure of nanocapsules and treated cotton fabric using FESEM and FT-IR indicated the spherical nanocapsules with size of 60-80nm stabilized on the fabric surface in a film layer feature. Also, the treated cotton fabric showed a good release behavior of 96h, a high stability against washing and rubbing tests and a relative good antimicrobial activity with 91, 89 and 94% reduction against S. aureus, E. coli and C. albicans, respectively.
微胶囊化是保护植物提取物在空气、光、湿度和高温条件下的挥发性和不稳定性的最佳方法。然而，将封装的植物提取物应用于纺织品需要低温和高速度的处理，以避免胶囊破裂或破坏。本文通过 UV 固化法，采用超声辐照辅助 W/O/W 微乳液法制备的纳米胶囊应用于棉织物。FESEM 和 FT-IR 分析表明，纳米胶囊呈球形，粒径为 60-80nm，稳定在纤维表面的薄膜层中。此外，处理后的棉织物表现出良好的释放性能（96 小时），耐洗和耐摩擦性能良好，对金黄色葡萄球菌、大肠杆菌和白色念珠菌的抑菌率分别为 91%、89%和 94%。
