아로니아 추출물 처리에 따른 의류용 직물의 염색성과 기능성 연구

Abstract

This study has analyzed the dye-ability and functional effects of a apparel materials. For this study, cotton and silk fabrics were dyed with Aronia extract. The study examines the Color difference, Colorfastness to Washing, Sunlight and Perspiration, and Allergenic Disperse Dyes. As a result of surface color test, RB color and Red Purple color appeared on Al pre-mordanted and non-mordanted cotton, Al pre-mordanted and non-mordanted silk. While GY color was extracted on the Fe post-mordanted cotton, GB color appeared on the post-mordanted silk. The test result demonstrates that a wide range of colors from Red-purple to Blue-green could be shown on the whole fabrics sample. Through the Lightness(L*)test, the result showed that lightness was higher in cotton fabrics. In terms of Chroma(C*)test, the post-mordanted silk fabrics had the lowest chroma while the non-mordanted silk fabrics had the highest chroma among samples. In addition, the test on color difference indicated that the silk fabrics had high color difference and the Fe post-mordanted silk fabrics showed the highest color difference. Particularly, the non-mordanted silk fabrics presented the highest chroma and color value. The test on colorfastness to washing showed low level at 1 on the whole sample. Also, the test demonstrated 2-3 level on colorfastness to light and to perspiration. In addition, the whole sample indicated‘ND(Not Detected)’results on the test for allergenic disperse dyes. Through the test results, it has been demonstrated that the aronia extract could be a safe dyeing material and it also contains superb pigments which are able to extract a wide range of colors from purple to blue green.
