The berberine from Amur cork tree is natural yellow dye and can be extracted more easily by water. The berberine is basic dye and was extracted at 90-95$^{\circ}C$. We have obtained the following results; 1. K/S value in the abstract of dye was increased by time-elapsing, but the reasonable time was between 90-120min. 2. The reasonable weight of Amur cork tree in the abstract of dye was between 10-20 g/L. 3. We obtained various colors in case of using mordants. ―In case of 10g/L and 20g/l, the reasonable value of mordant was 5-10%(owf). and in case of using tannic acid and $FeSO_{4}$ we could obtain high K/S value. 4. &{\lambda}_{max}& of UV spectra was shown 420nm. 5. Genarally fastness of drycleaning indicated more than grade 4. but it of perspiration was more stable in acid than alkali.

In this study, the colorants of Wisteria floribunda leaf were extracted with water. Silk and wool fabrics have been dyed with the aqueous extract of Wisteria floribunda leaf and their dyeabilities was studied. Additionally the fastness to washing, drycleaning, light and perspiration were also investigated. Silk and wool fabrics dyed with the extract of Wisteria floribunda leaf were colored in yellowish red tint. The optimum dyeing condition of the colorants extracted from Wisteria floribunda leaf was three repeated dyeing at 70, $95^{\circ}C$ for 1hr using post mordanting. For dyed silk and wool fabrics, the fastness to washing was improved by mordanting, and the fastness to drycleaning was very outstanding.

This study examined the dyeability, color fastness and functionality of cotton fabrics dyed with residual parts of cultivated Pteridium aquilinum. UV-Vis absorption spectrum, TLC and FT-IR spectra analysis showed that colorants of Pteridium aquilinum are a mixture of pyrogallol tannin and catechol tannin. Optimum dyeing conditions was confirmed colorant concentration of 500% at $100^{\circ}C$ for 60 minutes. Color fastness followed to washing, rubbing, perspiration and light as 4-5, 5, 4-5(acidic), 3-4(alkaline) and 2, respectively. Deodorization rates of ammonia($NH_3$) and acetic acid ($CH_3COOH$) were analyzed 88.8% and 78.0%. UV protection rate was 94.2% of UV-A and 96.8% of UV-B. UV protection factor(UPF) was 27. Therefore residual parts of cultivated Pteridium aquilinum could be used for a new functional colorant.

By introducing chitosan treatment prior to dyeing, examination was given to the effect of chitosan coated on the surface of fabrics on the color change of dyed fabric based on th e change of ${\Delta}E$, a*, and b* values. At the same time, the dyeing mechanism of Caesalpinia sappan dyestuff was predicted by the investigation of the change of air-permeability ac cording to the chitosan treatment. The change of elution was investigated by the examination of the elution of metallic ions employed as mordants after soaking dyed fabrics in the solution of alkaline perspiration ba sed upon the fact that chitosan carries excellent absorption ability toward metallic ions.

This experiment was conducted to determine the heat loss by the amount of perspiration from human body. Warmth keeping ratio determined by using cooling methods were as follows ; 1) The higher amount of moisture evaporation, the higher amount of heat loss was resulted 2) The cold feeling was found at the level of moisture content in clothes above 0.017 cc/$cm^3$ (amount of moisture evaporation; $160\times10^{-3}cc/cm^2{\cdot}min$) 3) There was no relationship between the characteristics of fabrics(kinds, density, were factor, moisture transpiration) and heat loss at the same moisture content.

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 is to investigate the dyeability, antibacterial activity on silk and rayon fabrics dyed with cochineal. The result are as follows; 1. The K/S value of silk fabric was higher than that of rayon fabric. 2. The optimum conditions are mordant concentration $0.5{\sim}1%$, dyeing material concentration 2.0%(o.w.f), dyeing temperature $60^{\circ}C$, PH 3 and dyeing time 30minutes. 3. Pre-mordanting method had higher dyeing absorption than post mordanting method in case of silk and rayon fabrics. 4. The antibacterial activity of dyed silk fabrics were higher than that of dyed rayon fabrics and the antibacterial activity was increased by mordanting. 5. The lightfastness and perspiration fastness of silk fabric were improved but these of rayon were not. Dyeing fastness was improved by Fe mordanting on both fabrics.

This study was conducted to survey the end-use properties of the commercial men's socks. Date were obtained from 16 samples of men's socks gathered from department store, markets, specialty chain and variety store in street. Stretchness, performance of rib top, fiber contents, strength (abrasion and bursting), pilling properties and color fastness of socks tested in this study were as follows. 1. Stretchness of socks was sufficient but elongation of rib top was insufficient, therefore these facts are getting to become problem to consumers. 2. Fiber contents of samples were not in accord with the labelled item and criteria of Textile Fiber Product Identification Act. 3. Strength and pilling properties were vaious in according to fiber contents of socks. Socks blended of synthetic fibers were superior to that pure natural fibers in strength but not in pilling. 4. Color fastness to perspiration and rubbing were sufficient on the whole, but fastness to laundering in stain were very insufficient.

Consumer consider the purpose for which they plan to use clothes when they purchase it, and the socks in textile products is evaluated in the same way. serviceability is judged by the extent to which the socks will be useful for its intended purpose. It should retain its original shape and size, good air permeability, good absorbency, good abrasion resistance, high fastness etc. Owing to importance of serviceability in socks, in this paper, these end-use requirement characteristics were tested. The results obtained were as follows: 1. Blend ratios were different between the indicated fiber contents on labels and the testing ones. 2. Air permeability was higher in the samples which contain less stitch density, and hydroscopicity was higher in those which contain natural fibers such as cotton and wool. 3. Shrinkage depended on the blend ratios of cotton and wool, and elastic recovery was better in the course direction than in the wale direction. 4. Pilling was conspicuous in the synthetic fibers such as polyester and nylon, and fastness of laundering and perspiration was higher in the fading grade than in the staining grade.

Dyeing properties of sargent cherry of Prunus sargentii Rehder were investigated with silk fabrics. The absorbed wave lengths at UV-VIS spectrometer were 362nm, 386nm, 430nm, and 512nm. The K/S value showed high in following conditions: 100%(w/w) stock solution, 60 minutes of dyeing time, 80$^{\circ}C$ of dyeing temperature, and 5 times of dyeing repetition. The K/S value showed higher in post-mordant than in pre-mordant, and the change of color did not appear in pre-mordant samples. They were colored greenish yellow in post-mordanted Cu and Fe. The highest dyeability and $\Delta$E showed in post-mordanted Fe. The light fastness showed 3-4 in post-mordanted Fe, 1-2 in pre-mordanted Al, and washing and perspiration fastnesses showed also good results in post-mordanted Fe.
