This study examines the dyeability of fabrics in relation to dyeing temperature, time, concentration, and the number of repeated dyeings. For this study, at first we extracted natural dyes from the peel of C.umshiu mandarin, which is fast as a dye and considered as recycling agricultural wastes. Additionally, it represents the image of Jeju Island. Then, we dyed cotton, wool, silk and nylon fabrics with the extracted dyes. The findings of this study are as follows. 1) Dyed cotton, wool, silk and nylon fabrics with the extract of C.umshiu mandarin peel are generally yellow. 2) Wool, nylon, silk, and cotton, in this order, are of good dyeability; Wool fabrics have the highest dyeability and cotton fabrics have the lowest. The dyeabilty of cotton fabrics was not improved even after dyeing in different conditions. 3) Colorfastness with washing, rubbing and perspiration are all good, while colorfastness with light is poor. 4) Higher dyeing concentration makes better dyeability. 5) Dyeability is enhanced as the dyeing temperature increases, while the dyeability of silk and nylon is relatively good even at low temperatures. 6) Looking at dyeability according to dyeing time, the longer the dyeing time, the better the dyeablility. Sixty minutes of dyeing time is appropriate to dye fabrics. 7) With an increase in the number of repeated dyeings, increased dyeability is obtaihed.

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%).

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.

The purpose of this study was to increase the ultraviolet-light (UV)-cut ability of cellulose fabrics (cotton, ramie, and rayon) dyed with safflower yellow colorants. For this purpose, samples treated with UV-cut agent and tannic-acid were compared with the untreated samples after UV exposure in terms of K/S value, color changes(${\Delta}E$), SEM, and strength retention. The K/S value rapidly decreased after 28 days exposure, whereas the K/S value of the samples treated with both UV-cut agent and tannic-acid decreased to less than that of the untreated samples. In color changes, $L^*$ increased while $a^*$ and $b^*$ decreased, indicating less red and yellow character in color. This induced a change in the hue, value and chroma values. However the color change(${\Delta}E$) of the samples treated with both UV-cut agent and tannic-acid was less than that of the untreated samples. Scanning electron microscopy (SEM) pictures showed a severe degradation by exposure in all samples. Tensile strength rapidly decreased after 28 days for cotton and rayon, and after 21 days for ramie. However, the strength retention of the samples treated with UV-cut agent and tannic-acid was higher than that of the untreated samples.

In this study, the dyeing conditions(temperature, time, concentration) are changed from various conditions on wool fabrics by using corydalis tuber extract in order to develop new natural dyes. The purpose of this study is to improve the dyeability, color fastness, and functionality and to derive optimal dyeing conditions by comparing and analyzing the changes of K/S values and surface color by dyeing pH changes, mordant method, and mordant type. As a result of the experiment, the optimum dyeing condition of the wool fabrics is shown dyeing temperature:$80^{\circ}C$, dyeing time:90min, dyeing concentration:100%. The dyeability by pH variants of corydalis tuber extract indicates that K/S values is higher alkaline than acidic. The mordant method of corydalis tuber extract showed pre-mordant has high K/S values. In terms of color fastness, marked improvement has not been shown despite of mordant treatment on wool fabrics. In particular, color change of color fastness to washing, color fastness to light indicates the low fastness. In addition, the functionality such as antibacterial activities and deodorization can be given at dyeing with corydalis tuber extract thus it is expected to be applied to underwear or apparel products for the elderly and infirm and children with weak skin that required high functionality.

This study investigates the dyeability of soybean protein fabric after dyeing with gallut. In this study, the colorants of gallnut were extracted with boiling water at $60^{\circ}C$ and 60min. Soybean protein fabric was dyed with extracted solution from gallnut according to concentration, temperature and time. After dyeing with gallut solution, dyeability (K/S) was obtained by CCM observation. Al, Cu and Fe were employed as a mordanting agents. Various color changing were produced by the interactions of mordants that were different from soybean protein fabric; however, Al mordant was not indicated as a variable color change. Fastness to washing and light were also investigated. Consequently, the dyeability of the soybean protein fabric dyed with gallut showed reasonable results at 100% o.w.f, $90^{\circ}C$, for 60min. Fastness to washing according to concentration indicated good result as more than grade (4-5) in general. Fastness to light was almost the same compared to fastness to washing at all concentrations. Fastness to washing according to mordants indicated good grade (4) in principle at Al, Cu, and Fe; in addition, fastness to light indicated a good grade too. Fastness to light also indicated the highest dyeability at Fe mordant. This study shows that gallut is a reasonable dyestuff to soybean protein fabric and that it is possible to manufacture a variety of products that use soybean protein fabric.

This study investigated the substantivity of anionic dyes for cationic-modified new rayon (cocell) fabric treated with cationic agent (CA), 3-(Chloro-2-hydroxypropyl)-trimethylammonium chloride (CA). We also investigate the dyeability of cationic-modified new rayon fabric after dyeing with gallut. CA was converted in an aqueous solution of sodium hydroxide into epoxypropyl trimethylammonium chloride. Treating with this epoxy reagent modified the hydroxyl groups of the new rayon fabric into the trimethylammonium group through ether linkage. The introduction of new cationic sites into new rayon fabric by pretreating with cationic agent improved the substantivity of the Gallnut dye with the new rayon dyebath. The degree of the cationization of cationic-modified new rayon and cotton fabric was evaluated by nitrogen (N) content. This study extracted the colorant of gallnut with hot water at $90^{\circ}C$ and 120 min. Cationic-modified new rayon fabric dyed with extracted solution from gallnut according to concentration of gallnut, dyeing temperature, dyeing time and concentration of cationic agent. Dyeability (K/S) was obtained by CCM observation after dyeing with gallut solution. In addition, fastness to washing and light were also investigated. The degree of crystallinity of new rayon and cotton fabric were 42.15% and 54.94%, respectively. N (%) content of cationic-modified new rayon was higher than the cationic-modified cotton. Dyeability (K/S) increased significantly with the increasing concentration of CA and gallut.
