This study investigated EEG signal, subjective fragrance sensation, and the preference of differently colored cotton knit treated with Citrus unshiu oil containing microcapsules as well as examined their relationships for providing regression models on subjective fragrance preference. Color variables combining 2-level hue (Yellow and Green) and 3-level tone (strong, pale, and grayish) were applied by dyeing prior to microcapsule treatment. We invited 28 female college students aged 20's for EEG signal experiments and subjective fragrance sensations with fragrant knit by rubbing. EEG signals at $mid-{\alpha}$, $fast-{\alpha}$, and $low-{\beta}$ showed significant differences depending on color; Green had more relative power values and grayish tone did more at $low-{\beta}$. Even though subjective sensation showed no significant differences depending on color, some of them such as Fresh, Comfort, and Natural showed significant correlations with EEG signal at $low-{\beta}$, which means that the fragrance sensations of Citrus unshiu fragrance are concerned with attention and alertness for Koreans. Fragrance preference was regressed significantly using some EEG signals and subjective sensation. The results could be utilized to value up fragrant textiles by Citrus unshiu oil.

Wall-material을 멜라민-포름알데히드 수지, core-material은 솔향오일, 그리고 5종류의 계면활성제, Laurylbenzenesulfonic acid sodium slat (SDS), Polyvinylpyrrolidon (PVP), Polyvinyl alcohol (PVA), Span-80 및 2-Acrylamido-2-methyl-1-1 propanesulfonic acid (AMP)을 사용하여 섬유제품용 향기 나는 마이크로캡슐을 제조하였다. 향기 나는 마이크로캡슐의 모양 및 형태는 계면활성제의 종류에 따라 다르다는 사실을 알았다. 더 나아가 항균성 및 향기 나는 마이크로캡슐을 제조하기 위하여 방사선법으로 은 나노콜로이드를 제조하고, 이 콜로이드 용액에서 마이크로캡슐의 제조도 시도하였다.
