The purpose of this study is to develop a natural functional material with insecticidal properties and antimicrobial activity for the application of emotional robot development for the early treatment use of children with autism spectrum disorder. As a part of the study, I investigate the antimicrobial activity of silk fabrics dyed with jasmine tea and jasmine petal tea extracts. Bacteria used for the test of antimicrobial activity were Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352. The presence of phenol, known as an antimicrobial component, was measured from jasmine tea and jasmine petal tea extracts. UV-Vis analysis and FT-IR analysis were also employed. Silk fabrics dyed with jasmine tea extracts appeared to have significant antimicrobial activity of 99.9% for S. aureus, regardless of dyeing concentration. On K. pneumoniae, silk fabrics dyed with stock solution and onehalffold diluted solution of jasmine tea extracts presented significantly high antimicrobial activity of 99.9%. In contrast, no antimicrobial activity was observed from all silk fabrics dyed with jasmine petal tea extracts, regardless of the type of bacteria. On S. aureus following 20 hours of irradiation, silk fabrics dyed with jasmine tea extracts presented high antimicrobial activity of 93.3%, regardless of dyeing concentration. On K. pneumoniae after 20 hours of irradiation, only the silk fabric dyed with a stock solution of jasmine tea extracts appeared to have any antimicrobial activity (40.6%). On S. aureus after dry cleaning, silk fabrics dyed with jasmine tea extract had significantly higher antimicrobial activity of 99.9%, identical to its effectiveness before dry cleaning, regardless of the dyeing concentration. On K. pneumoniae after dry cleaning, silk fabrics dyed with stock solution and onehalffold diluted solution of jasmine tea extracts had significantly higher antimicrobial activity of 99.9%, identical to their effectiveness before dry cleaning. The total phenol content was higher in the jasmine tea than in the jasmine petal tea. From the results of UV-Vis analysis, the ethanol extraction solution of jasmine tea and jasmine petal tea had absorption maximums of λmax at 272㎚ and 277㎚ (λmax of tannin is 272285 nm), respectively. From the results of FT-IR analysis, jasmine tea and jasmine petal tea showed three main common absorption bands in the 1750-700 ㎝-1 range: 16151606, 15181507, and 10431030㎝- 1. Therefore, it was able to be determined that the form of tannin obtained in jasmine tea and jasmine petal tea is a kind of hydrolyzable tannin.
