본 연구에서 소목 및 코치닐로 염색한 견직물, 그리고 소목과 황벽 및 코치닐과 황벽 복합 염색한 견직물의 염색성 및 기능성을 고찰하였다. 그 결과, 소목으로 염색한 견직물의 색상은 2.2R의 적색계열, 코치닐로 염색한 견직물은 3.0RP의 적자색 계열, 소목과 황벽으로 복합 염색한 견직물의 색상은 2.7YR로 주황색계열, 그리고 코치닐과 황벽으로 복합 염색한 견직물의 색상은 4.3R로 적색계열을 나타내었다. 항균성의 경우, Staphylococcus aureus에 대해서 코치닐로 염색한 견직물을 제외한 나머지 세 종류의 염색 견직물은 균 감소율이 91.1% 이상으로 우수한 항균효과를 나타내었다. 그리고 Klebsiella pneumoniae에 대해서 소목과 황벽 및 코치닐과 황벽으로 복합 염색한 견직물의 균감소율이 99.9%로 뛰어난 항균효과를 나타내었다.

첨단과학기술의 발달로 환경오염이나 자연파괴 등을 유발시킴으로써 이에 부응하여 다양한 기능이 부여된 소재들이 개발 되고 있어 천연성분을 이용한 패션상품들이 고부가치를 창출하고 있다. 본 실험에서는 Kumazasa를 충분히 건조시켜 키토산을 젖산 수용액에 용해시켜 면을 처리 하고 욕비 1:10으로 Kumazasa를 24시간 80$^{\circ}C$에 가열하여 얻은 추출액으로 염색하여 수세 및 건조하였다. 항균성은 황색포도당구균과 폐렴구균에 대한 항균성을 조사한 결과 모두 99.9%로 매우 우수한 항균성이 나타났다.

Amur cork tree contains yellow natural basic dye largely used for dyeing on silk. Dyeabilities and fastnesses of the colorant on silk fabrics were investigated , According to dye concentration, pH, temperature, time of pre- and post- treatment of mordant, K/S values and fastnesses of the silk fabrics were examined. As a results, K/S values of dyed silk fabrics were increased by pre- and post-treatment with chinese gallotannin. The optimum condition of chinese gallotannin pre-treatment was 0.15% concentration, pH 4, 70℃, and 45min, and that of post-treatment was 0.05% concentration,60℃, and 30min. The wash fastness and the light fastness were enhanced to 4 grades and 2∼3 grades.

In order to improve dye uptime and wash fastness on dyeing of cotton fabrics with Amur cork tree, twitter ionic groups, acid groups, hydrophobic groups or cross linkage were introduced into cotton fabrics. Results obtained were as follows, 1 The optimum modification of cotton fabrics was carbosy methylation in the water solution containing 15% sodium chloroacetate and 15% sodium hydroxide and then introducing hydrophobic groups by treating in the solution containing $30m\ell$ DMSO and $3m\ell$ 2,4-TDI 2. Numbers of carbon, diisocyanate group than monoisocyanate group and aromatic compound than aliphatic compound in introduced hydrophobic groups were effective. 3. The dye uptake and wash fastness wore enhanced significantly by treating only with 2,4-TDI. 4. The wash fastness seems to correlate to the degree of swelling of the fabric during washing and also depend on the Interaction between dyes and acid groups as well as hydrophobic groups.

The optimum rendition of chinese gallotannin pre-treatment was 0.15% concentration, pH 4, $70^\circ{C}$, and 45min, and that of post-treatment was 0.05% concentration,$60^\circ{C}$, and 30min. The wash fastness and the light fastness were enhanced to 4 grades and 2~3 grades.

In this study, wool, silk and cotton fabrics were dyed with natural dyes derived from Ginkgo biloba bark using various mordants, and their dyeabilities were discussed. Additionally the fastness to washing, perspiration, light, rubbing, and drycleaning were investigated. And the effects of bacteria reduction and UV-B protection rate were also checked. The optimum dyeing condition of the colorants extracted from the Ginkgo biloba bark was three repeated dyeing at$95^\circ{C}$ for 1 hr. by using post mordanting. Mordanting improved the fastness to washing, Perspiration and drycleaning, but the fastness to light and rubbing were not increased. The bacteria reduction rate of the wool fabric increased drastically by dyeing with extract of Ginkgo biloba bark and its effect maintained after repeated washing and drycleaning. UV-B protection rate of the natural fibers increased by dyeing with extract of Ginkgo biloba bark and the dyed wool fabric was the best of the three fabrics.

The purpose of this study is to improve the dyeability and the color fastness to light of cotton fabric dyed with extraction of cinnamon cassia. Cotton fabric was pretreated with chito-colla to enhance the dyeability, and K/S values were compared chito-colla pretreated fabric and untreated fabric. In addition, to improve of color fastness to light of dyed fabric, it was used FFC compound as mordant. Also, it was measured SOD-liked activity of FFC compound and lifht fastness of dyed fabrics. The results are as follow; K/S value of cotton fabric pretreated with chito-colla(5%) was much more increased than untreated fabric. SOD-liked activity of FFC compound was observed over 70%. Light fastness of cotton fabric treated with FFC compound was 3～4 grades.

The purpose of this study is to investigate dyeing properties of wool fabric with walnut colorants. Walnut colorants were extracted with water from walnut hull and characterized by FT-IR analysis. Effects of dyeing conditions and mordanting on dyeing properties and colorfastness were studied. Results obtained were as follows, 1. Higher K/S value was obtained at higher temperature and longer dyeing time, the highest K/S value was shown at 100℃, 60min. 2. Dye uptake was increased with the increase in colorants concentration up to 2%. Higher K/S value was obtained at acidic condition. 3. Mordanting was not effective for improving dye uptake and colorfastness and for changing color of the dyed fabric.
