This study was to investigate categories of valuation and make the standard on developing valuation of natural dyes by Delphi method. The three-round Delphi tests were performed with 36 professional in the academic, the industrial, and the art field.'Dyeability property' meant levelling, adsorption, color diversity with mordant, color stability, 'marketability', possibility of mass production, economical efficiency, functionality, demand and supply of natural dyes, 'color', yield, beautiful color, value of color and 'color fastness', washing, perspiration and light fastness. Indigo, persimmon, cochineal, safflower and onion in dyeability property were evaluated highly, functional natural dyes in marketability, red and purple color ones except indigo in color and ones containing tannin in color fastness.

The purpose of this study was to value the present condition of natlwal dyeing, to forecast needs in natural dyeing world and to off the preliminary data on future direction of research and enhancement plan. The three-round Delphi tests were performed with 36 professional in the academic, the industrial, and the art world. The result of the study is as follows: Factor analysis showed the troubles were classified into 4 categories; 'dyeing', 'basis', 'industry' and 'consumer and environment'. Supplementary measures and future direction research 3categories; 'development', 'education' and 'mass production' And commercialization. popularization 2 categories; 'commercialization' and 'popularization'. 'Dyeing' is correlated with 'mass production', 'basis' with 'education' and 'education' with 'commercialization' and 'popularization'. The engaged period in natural dyeing world is longer, professionals were more concerned about 'consumer and environment' The most influential element of the present question in the view is 'education'.

This study was aimed to consider the influence of hue-tone, dyes, and mordants of naturally dyed silk fabric on color sensibility image factors and to establish color sensibility image scales of naturally dyed silk fabric by color and image descriptors. By single or sequential dyeing with various natural dyes commercially available in domestic and foreign market on the same silk fabric, a total of 66 colored fabric stimuli were prepared and they were used to evaluate subjective color sensibility image by 40 participants. As results, four different color sensibility image factors for naturally dyed silk fabric, 'delight', 'natural', 'modern' and 'attractive' were extracted. All of factors were significantly influenced by hue-tone, dyes, and mordants. Furthermore, by using color sensibility image adjectives and colors, multidimensional image scales were established, which leads to the conclusions that the results of this study help to design color sensibility-oriented naturally dyed fabric and apparel products.

섬유제품 중 의류용으로 소비자들이 가장 많이 선호하는 것은 면 섬유이고, 그 중 니트제품이 차지하는 비율은 약 절반 정도이다. 면 섬유가 갖는 여러 가지 장점들을 대체하기 위하여 여러 가지 합성섬유가 개발되었으나, 천연섬유에 대한 소비자 인식이 높아지면서 스판덱스와 같은 탄성섬유를 제외한 합성섬유 소비는 점차 줄어들고 있는 반면, 면 섬유와 천연 원료에서 추출하는 모달, 텐셀, 라이오셀 등의 셀룰로오스계 신 소재는 그 소비가 증가하고 있는 추세이다. (중략)

The purpose of this study was to develop high-quality naturally dyed leisurewear with images of traditional Korean clothing that keeps a psychologically comfortable and physically pleasant environment at home and in vacation spots. The root bark of elm trees, the atopic skin, is also known to be effective for the relief of rhinitis and atopic diseases as well as stress and insomnia. However, there is insufficient color in the bark for the dyeing of fashion products, so to compensate for the lack of color, for dyeing purposes it was combined with a composite extract called Rubia akane Nakai resulting in a relatively bright red color. Except for the light fastness, all the fastnesses were rated 4 to 5, showing excellent results. Through complex dyeing using elm bark and pods extract the author produced four high-quality vests, one-piece, a gown, and jeogori-pantsuits of silk materials with Korean images that are suitable wear for relaxing comfortably at home and during breaks and which provide a comfortable and physically pleasant experience. The vest was made with the formal style of Bae-ja and Dang-eu, the dress is made of Cheok-lik, and the gown is made of Wonsam. It will be meaningful at a time when the importance of rest is increasing due to the healing clothes worn by busy modern people.

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.

The main purpose of this exploratory research was to examine the characteristics of consumers who patronize natural-dyed clothes and their perceptions regarding natural-dyed clothes. Thirty three participants who have worn natural-dyed clothes were interviewed for the study. They were asked about the styles and price of natural-dyed clothes they owned, their evaluation on them, and the lifestyles of themselves. Existence of subculture among the interviewes and its characteristics were also probed. The results indicated that natural-dyed clothes are relatively high-priced, mostly of modified hanbok style, and became popular in recent years. Interviewees frequently mentioned uniqueness and comfort as the main benefits of natural-dyed clothes, and expressed dissatisfaction regarding color fastness, easy care and problem of coordination. The consumers of natural-dyed clothes appeared to have strong preferences for environment conservation and Korean traditional culture. They also seemed to form a subcultural group who have commonality in their involvement in Korean cultural activities, mainly tea ceremony.

The effects of monazite and fixing agents on cotton fabric dyed with Perilla frutescens var. acuta extract were investigated. The proper monazite treatment concentration, temperature and time were 10%(o.w.b.), $50^{\circ}C$ and 60minutes. By various fixing agent treatment, $FeSO_4$ showed a relatively high K/S value and the order of K/S value decreased as follows, cation surface active agents, soybean and NaCl. And the monazite and $FeSO_4$ fixing agent showed higher anion emissity than those of untreated cotton and other fixing agents. The cotton fabrics showed improved color fastness by monazite and fixing agents treatments with the exception of light fastness. And the cotton fabrics fixed with fixing agents were showed effective bacterial reduction with the exception of NaCl.

The natural dyeing of cotton fabric with Perilla frutescens var. acuta extract was investigated. The proper extraction temperature and time were $100^{\circ}C$ and 120 minutes. The proper temperature, time and colorant powder concentration for the dyeing of cotton fabric with Perilla frutescens var. acuta powder were $90^{\circ}C$, 60 minutes and 15%(o.w.b.), respectively. In various mordanted methods, the K/S values of simultaneous-mordanted methods were higher than those of pre-and post-mordanted methods. And the Cu-and Fe mordant showed higher K/S values than those of other mordants. Light colorfasness of mordanted cotton fabric was poor, but the other colorfasnesses were shown to be good. The cotton fabric mordanted with Cu mordant was showed effective bacterial reduction.
