In this study, the objective was to develop a long-lasting mosquito repellent textile by synthesizing silk-based lavender oil microcapsules and applying them to cotton fabric. Lavender oil, derived from Lavandula angustifolia, was chosen as the plant-based material. The microcapsules’ morphology and the fabric’s surface were examined using optical and scanning electron microscopes. Dynamic light scattering was utilized to measure the capsule size and zeta potential. The mosquito repellent efficacy was evaluated through cage tests before and after multiple wash cycles and after exposure to different environments. A cytotoxicity assay was conducted on functionalized fabrics in order to assess their biocompatibility. Additionally, comfort properties such as breathability and water absorbency were assessed and compared to a control fabric. The results indicated that a higher concentration of lavender oil microcapsules (15 wt%) on the fabric exhibited excellent mosquito repellent efficacy (95.7%) prior to washing, which remained effective as 84.5% even after 40 washes. Furthermore, the functionalized fabric maintained its repellent properties following exposure to temperatures of 25 °C and 37 °C for 4 weeks. The cytotoxicity results indicated that the functionalized fabric exhibited non-toxic properties toward L929 cells, thereby confirming its favorable biocompatibility. This study successfully demonstrated the synthesis and application of silk-based lavender oil microcapsules on textiles, resulting in highly durable mosquito repellent fabrics effective against Aedes aegypti mosquitoes. These findings highlight the potential of this eco-friendly approach for developing effective and long-lasting mosquito repellent textiles.

在这项研究中，目的是通过合成丝基薰衣草油微胶囊并将其应用于棉织物来开发一种持久的驱蚊纺织品。从薰衣草中提取的薰衣草油被选为植物材料。使用光学和扫描电子显微镜检查微胶囊的形态和织物表面。利用动态光散射来测量胶囊尺寸和 zeta 电位。通过多次洗涤循环前后以及暴露于不同环境后的笼内测试来评估驱蚊效果。对功能化织物进行细胞毒性测定，以评估其生物相容性。此外，还评估了透气性和吸水性等舒适特性，并与对照织物进行比较。结果表明，织物上较高浓度的薰衣草油微胶囊（15 wt%）在洗涤前表现出优异的驱蚊效果（95.7%），即使在洗涤40次后仍保持84.5%的驱蚊效果。此外，功能化织物在 25°C 和 37°C 的温度下暴露 4 周后仍保持其拒水性能。细胞毒性结果表明功能化织物对L929细胞表现出无毒特性，从而证实了其良好的生物相容性。这项研究成功证明了丝基薰衣草油微胶囊的合成和在纺织品上的应用，从而产生了高度耐用的驱蚊织物，可有效对抗埃及伊蚊。这些发现凸显了这种环保方法在开发有效且持久的驱蚊纺织品方面的潜力。
