Abstract:
This study was aimed to develop the KaempferiaParviflora Oil (KPO) microcapsules for textile application, KPO antibacterial had been tested against Staphylococcus aureus (ATCC 6538) and Klebsiellapneumoniae (ATCC 4352) and its effects against these two different kinds of bacteria were significantly different at p<0.05. In this study, the KPO was encapsulated in Poly-l-Lactic Acid (PLLA) to make microcapsules by an emulsion polymerization and the prepared capsules were then analyzed by means of Scanning Electron Microscope, SEM) and Thermo-Gravimetric Analysis, TGA). It was found that through an optical microscope the developed KPO microcapsules could be seen in three-dimension sphere shapes. The particle sizes of these microcapsules ranged between 10 – 150 μm. and their average particle size was 23.881 μm with the standard diviation of 2.801. When the KPO microcapsules were applied to finish onto the following three kinds of cotton fabrics: cotton, polyester and nylon, to study the antibacterial property of the KPO microcapsules
before washing, the result showed that the KPO-finished nylon fabric with a warp knitted structure displayed the most efficient antibacterial performance and after 5-time washing, it could be seen through the scanning electron microscope that the microcapsules still remained on the nylon fabric.
