This study explores the solution of a variety of conditions of the natural dyeing with the Mulberry. To obtain this, the Cu complex compound was added into the extracts. The Mulberry extract was added the Copper acetate to obtain the Black sediment the metal complex compound of anthocyanidin. According to the result of using the complex compound of the solid material, the dyeing properties were excellent. The metal complex compound acted as a mordant, thus it reduced the process of mordanting in the natural dying.

The natural dyeing of silk fabric with Rheum undulatum L. extract was investigated. The proper colorant concentration, dyeing temperature, dyeing time, and pH for the dyeing of silk fabric with Rheum undulatum L. extract were 90% v/v, $90^{\circ}C$, 80 minutes and pH 3, respectively. In various mordanted methods, the K/S values of mordanted methods were higher than those of unmordanted methods. Light colorfastness of mordanted silk fabric was improved by mordanting. The antibacterial properties of dyed and mordanted silk fabric showed a high reduction rate, and Cu mordant was showed the most effective bacterial reduction.

본 연구는 우리 야생화중 비교적 대량번식이 가능한 종인 산비장이의 줄기, 꽃, 잎을 채취하여 염액을 추출하고, 다양한 염색 조건에서 견과 면 소재를 염색하여 염색거동을 살펴보고 염색된 색상에 대하여 고찰하여 다음과 같은 결과를 얻었다. 1. pH에 따른 염색에서 견은 pH가 낮을수록 진하게 염색되었고 면은 pH가 중성일 때 가장 진하게 염색되었다. 2. 염색온도에 따른 염착량은 견과 면 구분 없이 큰 차이가 없었다. 3. 염색시간이 1시간에서 2시간 사이에서 급격한 Y값의 감소를 보여 이 시간대에서 많은 염착이 이루어 졌다. 4. 면은 염 첨가 농도로 높을수록 Y값이 낮아져 염이 촉염효과 역할을 하는 것으로 보여 졌으나 견의 경우 염첨가에 따른 Y의 값은 큰 변화가 없는 것으로 나타났다. 5. 염액 농도에 따른 염색성은 견, 면 모두 농도가 작아지면 염착량이 작아졌다. 6. 견의 경우 매염제의 대한 매염효과가 높게 나타나고 있으나 매염제 농도는 큰 영향을 미치지 않았다. 면에서 철(Fe)과 구리(Cu)에 대한 매염효과만 조금 있었다.

본 연구의 목적은 적색계 천연염료를 이용한 견직물의 무매염 염색을 다룬 국내논문들을 고찰하여 무매염 염색의 염색성을 알아보는 것이다. 연구대상인 천연염재는 자색 고구마, 봉선화, 오디, 광나무 열매, 구아바 잎, 단삼, 히비스커스 꽃, 복숭아나무 전정가지로 총 8가지이다. 염색실험의 결과는 색차식에 의하여 $L^*$, $a^*$, $b^*$, C 및 ${\Delta}E^*$와 Munsell표에 의한 H V/C, Kubelka Munk식에 따라 K/S값을 산출하여 표면색을 측정하여 살펴보았다. 염색실험 변인은 염액농도, 염색온도, 염색시간, 염색반복횟수이며, 변인의 변화에 따라 염색성과 색채특성을 알아보았다. 문헌고찰 결과, 염색실험 변인은 견직물에 대한 천연염료의 염착성과 상관관계가 있을 뿐만 아니라 적색 발현에도 상관관계가 있었다. 본 연구를 통해 천연염색 과정에서 환경오염을 일으키는 반복적인 염색이나 매염제 사용 등을 하지 않아도 적색이 다양하게 발현되고 염색성도 우수할 수 있음을 보였다.

Fabrics dyed with artemisia extract have quite natural and elegant tones of color. This study purposed to find the best one for dyeing among artemisia collected in the four seasons in order to develop a more efficient method of dyeing with artemisia. As for the method of research, the researcher dyed wool fabric and silk fabric with artemisia, and measured dyeability according to the number of repeats of dyeing, coloration by post-mordant, color fastness to washing, color fastness to dry cleaning and color fastness to light. The results are as follows. 1. In dyeing with artemisia, dyeability was improved as the number of repeat of dying increased, and it was higher in wool fabric than in silk fabric. 2. Among artemisia collected in the four seasons, autumn artemisia had dyeability much inferior to that of artemisia from the other seasons, and winter artemisia had the best dyeability. 3. According to the result of treating fabric with post-mordant, the dyeability was improved significantly, and coloration was most remarkable when copper and iron mordant were used. 4. The color fastness to washing and color fastness to dry cleaning of fabric mordanted with artemisia were as high as grade 4-5 and grade 5 respectively. The color fastness to light was highest in winter artemisia as grade 4.

Yellow dye-stuffs in natural plant were extracted from a gardenia, saffron, safflower, amur tree and pagoda. And then they were used to color Korean handmade paper(Hanji) on using a mordant. The results of the degree of discoloration are as follows. 1. As for a gardenia(Gardenia jasminodes Ellis for. grandiflora Makino), the effects of coloring were outstanding in the acid area. But for the preservation, it might be desirable that used a lye in a dye-stuff obtained at $40{\pm}5^{\circ}C$. 2. As for saffron(Curcuma longa L.), when used alum as a mordant, it was colored to a medium yellow color with green color. But easily discolorated and was not desirable. And, it didn't fit in a dye-stuff of Hanji. 3. For safflower(Carthamus tinctorius L.), when pH was in the low acid it was colored to the cleaner yellow color. It was the distinction of discoloration that the degree of brightness's increase was low. 4. For amur cork-tree(Phellodendron amurense Rupr.), the effects of yellow coloring were great in the areas of acidity and alkali. But, when used alum, the degree of the discoloration was high and was not effective. 5. For pagoda tree(Styphnolobium Japonica L.), using a calcium hydroxide as a mordant, enabled the more than average yellow to be gained. The degree of discoloration was good.

This study aims to examine the antibacterial effects of cotton and silk fabrics naturally dyed with Artemisia princeps extract on antibiotic-resistant strains of bacteria. The concentrated natural dye of the Artemisia princeps extract was made at the liquor ratio of 1:10 at 40-60℃ for 60 minutes. The concentration of FeSO4·7H2O, Al2(SO4)3, and CuSO4 5H2O mordant was 3% (owf), and the liquor ratio was 1:20. In order to experiment on the antimicrobial activity of the naturally dyed fabrics, Methicillin-resistant Staphylococcus aureus (MRSA) ATCC 33591, was used by breeding it in Brain Heart Infusion Agar (BHA) containing Oxacillin (2㎍/ml), Fungizone (2.5㎍/ml), and Brain Heart Infusion broth (BHI; Detroit, MI, USA). As a result of examining the bacterial growth reduction rate on dyed cotton and silk fabrics against antibiotic-resistant strains, it was found that the copper mordant in cotton fabric shows the highest antibacterial activity with a bacterial growth reduction rate of 99.9%, and the non-mordant cotton fabric shows the lowest antibacterial activity with a reduction rate of 18.6%. In the case of the naturally dyed silk fabric, it indicates the highest reduction rate of strains in the Al mordanting (94.9%), and Cu mordanting (99.9%).

The study was about on the colorfastness of the natural vegetable dye. Impatient Balsamina was chosen as a speciesof the natural vegetable dye. It has a long history for Korean Women‘s grooming on the nail to be reddened, Actually those were very easy to gather and easy to extract the colors from the leaves and the flowers, Also Impatient Balsamina were abundant near our environment. So this was a cue as a natural dye for the wool fabric, This study was designed to testify the possibility of the Impatient Balsamina as a natural vegetable. First, 2 kinds of extracts from the Impatient Balsamina were prepared. Second, 2 kinds of mordants and 3 kinds of dyeing process were used. And the dyed wool fabric were evaluated the color index using Chroma Meter, the result was recorded as L$^*$, a$^*$, b$^*$ value(65.86, 16.40, 36.80). The effect of the mordants was more effective in Cr mordant than Al mordant in the color fastness and the color affinity. The very interesting results were in the colorfastness to the drycleaning, that was graded 4 to 5, but the colorfastness to light was low, graded 2. Impatient Balsamina was veryfied, it could be a natural vegetable dye for the wool fabric.

This study is to research on two phase printing method by use of colorants extracted from sappan wood. As for the research, printing effect of printing paste, streaming time, optimal mordant concentration, change of surface color and colorfastness were measured. This experiment showed that modified starch were best on surface color among the modified starch, sodium-alginate, guar gum. And the surface color was best when the steaming time was 60 minutes, mordant concentration 8%(ow.f). And for colorfastness experiment, colorfastness to drycleaning was good, but colorfastness to light and colorfastness to washing showed no desirable result.

This study is to research on printing method by use of colorants extracted from Sappan wood. As for the research, the stability of paste added by mordants, steaming condition, optimal mordant concentration, change of surface color and colorfastness were measured. The experiment showed that guar gum were stability among the sodium-alginate, modified starch, guar gum. And the surface color was best when the streaming time was 60 minutes, mordant concentration 3g/l. And for colorfastness experiment, colorfastness to drycleaning was good, but colorfastness to light and colorfastness to washing showed no desirable result.
