This study was to investigate the natural dyeing materials in domestic, trials to detect new Inula Britannica. An appropriate dyeing condition ;was bath ratio 1:20, 50% (o.w.f.)conc., $80^{\circ}C$, 50min. The K/S values of silk fabric was the most efficient for the pre-mordanting method. The value of dyed fabric was mostly dark, for the mordanting, the chroma was best clear when using the Cr-mordant, color difference was distinct when using the Fe-mordant. The antimicrobiality of Inula Britannica itself appeared as a 6mm halo zone, dyed fabric was excellent with result of over 90% in mordant. In the case of dye fastness, the drycleaning and wet cleaning fastness was excellent, rubbing and perspiration fastness was improved, and light fastness was over level 2.

The purpose of this study is to obtain the dyed-fabrics of the elaborate patterns using the natural dye powders extracted from Galla Rhois, Sophorae Flos Immaturus, Clove, Sappan Wood, Madder, Log Wood and Japanese Green Alder. Specific informations on the separation and powder-making of each colorant were disclosed. Appropriate printing paste preparation and printing conditions including the viscosity and mordant concentration in the printing paste were investigated. The dyeability and colorfastness of the screen-printed silk fabrics with the colorant powders were discussed in terms of practical applicability. The deodorization and antimicrobial activities of the silk fabrics screen-printed with natural dyes were also assessed.

The extracts drawn out from Sophora japonica by methanol was concentrated. Using this concentrate the silk was dyed, 400% conc. of dyeing material, $80^{\circ}C$ temperature of dyeing, 30 min time of dyeing. The K/S value of silk fabric was the most efficient for the simmordanting method. On the other hand, the amount of absorbed mordant the Cu-mordant was largest mordants. The surface colors on the dyed fabric depended heavily upon mordants or mordanting methods. For all cases, the value of the dyed fabric was dark. for the mordanting, color difference was distinct when using the Fe-mordant. Lightfastness of the color fastness was best in Cu-mordant. The Fe-, Cu- mordant showed the greatest antimicrobial activity.

The silk fabrics were treated with color solution extracted from leaf of Camellia. The depression effect of destruction and yellowing of silk treated with color solution, shift of UV-VIS spectra of color solution, color difference of silk fabrics by dyeing with acid dyes and drycleaning fastness of silk treated with color solution were studied. UV-VIS spectra appeared to hypsochromic shift by irradiation. The decrease of tensile strength and the elongation of the silk treated with color solution showed depressed but those of untreated silk increased by irradiation. The yellowness index of silk treated with color solution showed a little change by irradiation. The color difference after dyeing with several acid dyes on treated and untreated silk showed not remarkable changes. Dsrycleaning fastness of silk treated by color solution was excellent.

This study aims at developing of textile design expressed not only Korean natural image but also modern sensibility using fabrics dyed by tie dyeing with various natural dyes. And it attempts to practicality of high value-added goods revived traditional beauty. With the aqueous extract of various natural dyes, i.e., indigo, amur cock tree, onion's peel, citrus peel, mugwort, gromwell, sappan wood silk fabrics dyed by tie dyeing. Also various color changes were examined by mordants, i.e., aluminium sulfate, cupric acetate mono hydrate, ferrous chloride. With these fabrics, I made works using the techniques of applique, mola, fabric's connection and weaving. I think the developed textile design gave expression to natural image of Korean nation.

Walnut colorants were extracted from walnut hull and their dyeing properties on cotton were investigated. Effect of dyeing conditions on dye uptake and effect of mordanting on dye uptake, color change and colorfastness were explored. Walnut colorants showed low affinity to cotton compared with wool and its isotherm adsorption curve was Freundlich type. It was considered that hydrogen bonding and van der Waal's force were involved in the adsorption of walnut colorants onto cotton. The dyed cotton showed YR color and there was no significant color change as pH changed. The dyed cotton showed generally high colorfastness except fastness to washing and light. Mordanting did not improve dye uptake and colorfastness, and not affect color of the dyed cotton significantly.

The optical behavior of coloring matter extracted from onion's coats, the depression effects of destruction, yellowing and W transmittance of silk treated with color solution of onion's coats color difference of silk fabrics dyed with acid dyes and drycleaning fastness of silk treated with color solution has been investigated. The results are as follows : 1) The coloring matter extracted from onion's coats by alkali-acid method appeared properties of aglycon type. 2) &{\lambda}_{max}&of color solution extracted by distilled water was found at 280 and 327nm. 3) The decrease of tensile strength and the elongation of the silk treated with color solution were depressed but those of untreated silk were increased by irradiation of UV light. 4) The yellowness index of silk treated with color solution showed a little change by irradiation. 5) The UV transmittance of silk treated with color solution was decreased as increasing concentration of color solution. 6) The color difference after dyeing with several acid dyes on treated and untreated silk fabrics showed remarkable changes. 7) Drycleaning fastness of silk treated by color solution was excellent.

This paper surveys the mordanting and dyeing properties of Sophora japonica L. Appropriate extraction, dyeing and mordanting condition of Sophora japonica L. were determined, and the effect of mordanting method on dye uptake and color fastness of dyed fabric was investigated. The maximum absorbance of Sophora japonica L. solution was 367.6mn, rutin solution was 365.6mn. The color of Sophora japonica L. solution was affected at pH 2 and pH 8~9. The optimum temperature to extract Sophora japonica L. was during 1 hour in 8$0^{\circ}C$. The effective dyeing temperature and time of silk were 10$0^{\circ}C$, 60min. K/S value of dyeing fabrics was increased by pre-mordanting treatment, especially Fe, Sn, Cr. In the case of Sophora japonica L. light fastness was increased by Fe mordanting. Perspiration fastness was better in acidic solution than that in alkaline solution. Fastness to rubbing and dry-cleaning were good in general.

A multi-layer of the dye, natural colorant Berberine, was successfully developed by the self-assembly deposition from water-soluble cationic dye(Berberine chloride) and anionic polyelectrolyte PSS(Polysodium 4-styrenesulfonate) in aqueous solution via electrostatic attraction. The corresponding results on multi-layer were characterized by UV-Vis absorbance measurements. The growth of multi-layer formed by the sequential interaction was also determined. The findings measured by UV-Vis spectrophotometer showed that the bilayer deposition characteristic was linear and highly reproducible from layer to layer.

In this study, natural substance and mineral materials was used for architectural interior wallpaper. Because natural substance and minerals are environment-friendly material with moisture adsorption and desorption properties. Natural substance and mineral materials was evaluated in moisture adsorption and desorption properties. Also, in the diatomite, the pores were observed on SEM photographs. Thus, it is supposed that moisture adsorption and desorption properties were influenced by the microstructure of the pore. The wallpaper according to the ratio of the mixture was analyzed for physical properties and moisture adsorption & desorption properties. As a result, we developed a wallpaper having excellent hygrothermal performance.
