초록
본 연구에서는 검정팥 종피에 함유된 천연색소에 대한 연구의 일환으로, 천연염료로서의 적용을 위해 염색조건 즉 염색온도, 염색시간, 염색 pH, 욕비에 따른 K/S 값을 측정하여 적정 염색조건을 설정하고, 여러 매염제를 적용하여 색상변화에 미치는 영향 및 견뢰도를 측정하여 다음과 같은 결과를 얻었다. 1. pH에 따른 염색성에서는 견직물의 경우 pH 4에서 가장 염착량이 많았고, 면직물의 경우에는 주어진 범위 내에서 는 pH가 높을수록 염착량이 많았다. 2. 염색온도와 시간에 따른 염색성은, 견직물의 경우, 염색온도
In this study the natural colorant was extracted from black bean seed coat in aqueous solution and used to dye silk and cotton fabrics. To obtain the optimal dyeing conditions it was examined at various dyeing condition (temperature, pH, time and liquor ratio). The dyeing behavior and the depths of shade which were evaluated in terms of K/S and CIELAB color difference values of the dyed and mordanted fabrics were also investigated. The dyeing fastness evaluated standard light and wash fastness tests. The obtained results were as follows ; The most K/S value of silk and cotton fabrics were obtained when the pH was 4.0 and 4.8, respectively and it increased slightly with dyeing time passes when the dyeing temperatures were at
