  • 오징어에서 추출한 천연염료인 멜라닌 분말을 이용한 양모직물의 염색은 pH와 멜라닌 분말 농도의 변화에 따라 액비 20:1, 온도 $100^{\circ}C$에서 60분간 염색하였다. 5% owf의 멜라닌 분말을 사용하여 pH 4에서 염색 한 결과 6.6의 표면염착농도(K/S)를 보였고 면직물의 K/S보다 높은 염색성을 보였다.

  • The purpose of this study was to investigate the colorfastness of cotton and silk fabric dyed with extract of Lotus leaf princeps. The experimental items were classified into mordanting treatments, fabric components and kind of mordants. The experimental test was done by laundering, abrasion(dry/wet), perspiration(acid/alkali) , light fastness, color difference by C.C.M(computer color matching) system and K/S test. The summarized findings resulting from the experiment and investigation are as follows: In the C.C.M and K/S test on mordanting method and kind of fabrics, co-mordanting treatment method and protein fabric (silk) were the most effective. Especially, Fe mordanting treatment was higher than Al, Cu, Cr and none-mordanting. In colorfastness on the mordants, perspiration and laundering fastness showed high grade (4-5) but grades of perspiration(2-3/4) and light fastness(1-3) were low.

  • The purpose of this study was to investigate the antimicrobial activity, antimutagenic and anticancer effects and dyeing properties of the fermented indigo extract. The methanol extract of fermented indigo showed a strong inhibition effect on Trich. mentagrophytes and antimutagenic activities against aflatoxin B$_1$(AFB$_1$) in the Ames test using Salmonella typhimurium TA 100. We also found in vitro anticancer effects of the methanol extract of fermented indigo and it was evaluated by using Clone M-3 mouse melanoma cells and A431 human epidermoid carcinoma cells and exerted little cytotoxity against 3T3-L1 embryo fibroblast cell. In the relationship between the K/S values of cotton and silk fabrics dyed with fermented indigo and dyeing repeating times, the K/S values became higher as the repeating times were increased. The K/S values were high when the fabrics were dyed at low temperture. The K/S values of cotton fabrics were higher than those of silk fabrics. Changes of surface color of silk fabrics were higher than those of cotton fabrics after water fastness test, laundering, irradiation and treatment of acidic and alkaline perspiration.

  • 천연쪽 색소를 사용하는 의한 견직물의 염색 방법을 확립하고자 시험결과 환원제인 Sodium Hydrosulfite를 사용한 경우 염색온도가 3$0^{\circ}C$에서는 30분, 5$0^{\circ}C$에서는 10분 염색 한 것이 표면 염착농도(K/S)가 가장 높았고, 염색액의 pH 7.4 정도인 환원제 및 염료량을 4 g/l일 경우에 가장 높았다. 1회 염색직물의 표면염착농도(K/S)는 개선은 7.20, 기존염색 방법은 1.09이었으며, 염색 직물의 분리한 색소와 염료색소는 모두 청색색소와 적색색소의 2개의 성분이었고 분자량은 262이었으며, 기존과 개선 모두 정균율은 99.8%이상으로 항균성 이 우수하였다.
