The fabric, 100% Silk, was dyed with Atractylodes japonica extract solution. The effects of concentration of extracts (colorant), temperature of dyeing, time of dyeing and pH of dye bath were studied. As the concentration of extracts increased, color strength (K/S value) increased progressively. The K/S values increased with raising temperature, time and proper conditions were 80℃ and 80 minutes. Maximum K/S value was obtained at pH 3. The K/S values of mordanted fabrics were increased with increasing mordant concentration up to specific values. Surface color of dyed and mordanted fabrics were yellowish. Light color fastness of fabric with mordanting was fairly good 3/4 rating. The mordanted silk fabrics showed excellent antibacterial activity. The silk fabric dyed with Atractylodes japonica extract showed a superior UV protective property.

This study was designed to evaluate to acute oral toxicity and skin irritation of Chrysanthemum dye in Sprague-Dawley (SD) rats. SD rats were orally treated with Chrysanthemum dye at a dose of 0, 1 and 2 ml/kg body weight. After oral administration, the rats were observed for 14days. In primary skin irritation test, SD rats were dermally treated with Chrysanthemum dye and observed for 3 days. To ensure the safety of Chrysanthemum dye such as the following were observed and tested. We examined the body weight, the feed intake, the clinical signs, the ophthalmological test, the histopathological test, the mortality and skin irritation. As a result, no significant differences were found in body weight, feed intake and histopathological test between control and Chrysanthemum dye treated group. In the result of skin irritation test, Chrysanthemum dye did not induce erythema and edema after topical application. Primary irritation index was “0” in the test. Therefore, it is suggested that Chrysanthemum dye has no effect on acute toxicity and side effect in SD rats and is non-irritant material based on the score “0” of primary irritation index.

천연 갈색 염모제를 개발하기 위하여 한국자생 거북꼬리 추출물로 염색한 머리카락의 염색성 조사와 함께 세정횟수에 따른 색깔변화를 화학 염모제로 염색한 머리카락과 비교하였다. 거북꼬리 추출물로 머리카락을 염색한 결과 대조구에 비해 δE값이 11이상 나타났으며, 모두 YR계열로 염색이 되었다. 매염제 처리에 따른 δE 값은 사스레피나무 회즙을 사용했을 때 15.52로 가장 크게 나타났다. 거북꼬리 추출물로 머리카락을 염색 후 세정 횟수에 따른 L값은 사스레피나무 회즙처리구에서 가장 낮았고, a, b 및 δ 값은 사스레피나무 회즙처리구에서 가장 높게 나타났다. 염색한 머리카락을 30회 세정한 결과 L값은 화학염모제로 염색한 머리카락 보다 거북꼬리 추출물(사스레피나무 회즙 매염)로 염색한 것에서 낮게 나타났다. 염색한 머리카락의 세정횟수에 따른 a, b, 및 δE값의 변화는 화학염모제로 염색한 머리카락 보다 거북꼬리 추출물(사스레피나무 회즙 매염)로 염색한 것에서 적게 나타났다. 따라서 거북꼬리 추출물은 천연 갈색 염모제로서 실용성이 있는 것으로 나타났다.
