Antimicrobial and Mosquito Repellent Finish on Cotton Fabric Using Coleus Aromaticus Leaf Extract

ABSTRACT

In this study, the combined antimicrobial and mosquito repellency treatment on woven cotton fabric using microencapsulated Coleus aromaticus was optimized through Box Behnken experimental design tool. The methanol-based solvent extraction was carried out for the preparation of crude extract from coleus aromaticus. The microcapsules were prepared using Gum acacia as shell material and Coleus aromaticus leaf extract as core material. These capsules were applied over the Cotton fabric through pad-batch method. Three process parameters have been taken for optimization, such as microcapsule concentration (gpl), concentration of BTCA, and curing temperature. The treated fabrics were subjected to antimicrobial activity and mosquito repellency characterization. Subsequent to this, polynomial equation was developed for both antimicrobial activities, as well as mosquito repellency behavior. Through RSM analysis, the influences of each process variables on the response were analyzed. The optimum process parameters are such as the concentration of microcapsule 40gpl, the concentration of BTCA 67.5 gpl, and the curing temperature was 116°C. The combined desirability coefficient was found as 0.792. Further to this, SEM and FTIR studies were executed for the confirmation of microencapsulated treatment effectiveness.

抽象

本研究通过盒贝肯实验设计工具，对采用微胶囊的棉布织物进行抗菌和驱蚊联合处理进行了优化. 甲醇基溶剂萃取用于制备从果芳烃中提取的粗萃取剂. 微胶囊是用甘金合欢作为壳材料，用科勒斯芳香叶提取物作为核心材料来准备的. 这些胶囊通过垫批法应用于棉织物上. 进行了三个工艺参数的优化，如微胶囊浓度（gpl）、BTCA浓度和固化温度. 处理过的织物受到抗菌活性和驱蚊性特征的影响. 在此多项式之后，为抗菌活动以及驱蚊行为开发了多项式方程. 通过RSM分析，分析了每个过程变量对响应的影响. 最佳工艺参数为微胶囊40gpl浓度、BTCA 67.5gpl浓度、固化温度116°C等. 综合可取性系数为0.792. 此外，SEM 和 FTIR 研究也进行了，以确认微胶囊治疗效果.
