느릅나무껍질로부터 추출한 염액을 이용하여 면, 마, 모, 견, 나일론 섬유와의 염색성을 조사하였다. 각 섬유와의 최적 염색조건을 설정하였으며 합성매염제와 천연매염제를 사용하여 염색성에 미치는 매염제의 효과를 검토하였다. 또한 느릅나무껍질로 염색한 각 염색포의 세탁견뢰도와 일광견뢰도를 살펴보았다.실험결과 느릅나무 염색의 최적조건은 욕비 1: 40, $80^{circ}C$, 60분 이었으며 견과 나일론이 가장 잘 염색되었다. 견, 모, 나일론의 경우 매염제의 처리에 의해 염색성이 향상되었으며 매염제의 종류에 따라 색상이 크게 변화되어 다양한 색상을 얻을 수 있었다.
A natural dyeing makes fabrics look unique and elegant which cannot be obtain by synthetic dyestuffs. The natural dyestuffs are harmless to human, and it is easy to get them. Also, the natural dyestuffs are environmentally frendly, which is the anther merit for natural dyeing,We investigated dyeability with several fabrics (cotton, wool, ramie, silk and nylon) using an elm bark. We mordants(natural and synthetic). Also, colorfastness in dyed fabrics was estimated by laundering and light. The optimum condition of dyeability in elm bark was 60 min as time, $80^{circ}C$ as temperature and 1: 40 as bath ratio. The dyeability in silk and nylon was the best among the sample. The treatment of mordants improved the dyeability and colorfastness in silk, wool and nylon. We obtain various color by the mordants.
