This study was carried out to make a search for the usefulness of marigold plants (Tagetes erecta) as a natural dye. And we have also examined into the dyeability and antifungal activity of silk and cotton fabrics dyed with 2% powdered colorant and 1% liquid colorant. Almost surface colors of silk and cotton fabrics dyed with 2% powdered colorant and that dyed with 1% liquid colorant except for that treated Cu and Fe with mordants were shown by Y-level. $L^*$ values of silk fabrics dyed with 2% powdered colorant were 66.2 to 86.39, those $a^*$ values were -1.97 to 6.09, and those $b^*$ values were 13.69 to 35.97. And $L^*$ values of cotton fabrics dyed with 2% powdered colorant were 78.97 to 89.62, those a values were -3.39 to 0.38, and those $b^*$ values were 5.63 to 15.61 $L^*$ values of silk fabrics dyed with 1% liquid colorant were 34.37 to 85.57, those a values were -7.79 to 12.33, and those $b^*$ values were 15.13 to 82.91, And $L^*$ values of cotton fabrics dyed with 1% liquid colorant were 44.12 to 87.90, those $a^*$ values were -8.37 to 6.18, and those $b^*$ values were 11.65 to 78.87. Colorfastness of silk fabrics against light treated nothing with mordants and that dyed with 1% liquid colorant decreased for a little by second grade, however, that against washing, rubbing, perspiration and dry cleaning were increased over fourth grade. Colorfastness of cotton fabrics in terms of rubbing, light, and dry cleaning, except for washing and perspiration, were shown by over third grade, when that was treated nothing with mordants. Antifungal activities of silk fabrics treated nothing with mordants and dyed with 1% liquid colorant of marigold extracts were shown by 28.9% against Staphylococcus aureus. However, those of Al, Ca, Cu and tartaric acid mordanting were more than 25.5% against Staphylococcus aureus and Klebsiella pneumoniae.

The concentration of dye uptake and the fastness improved when cotton and silk fabrics were treated with chitosan, a natural polymer. In this study, the effect of chitosan treatment was reviewed after the printing of cotton and silk fabrics padded with chitosan. When the change of physical and mechanical properties of printed fabrics was reviewed (as the concentration of chitosan increased) the thickness and weight increased a little, and the air permeability increased significantly than those untreated with chitosan. The dye uptake increased, accompanying a darker color shade, and the wash fastness increased 1/2-1 grade. The analysis results of enlarged images of printed patterns indicated that the width and area deformations were minimal as the concentration of chitosan increased when compared to untreated fabrics. Therefore, the dyeability and pattern quality were excellent after printing the chitosan-treated cotton and silk fabrics with cochineal dyestuff.

The attractiveness of the textile fabrics are generally judged by visual or tactile evaluation methods. Since the surface of the textile materials are so diverse that the visual factors such as optical properties or luster of the fabrics are not easily measurable. While most of the cotton fabrics are not so much lustrous, calendering process could impart the cotton fabric better luster. Also, the general grade silk-like polyester fabrics resemble silk fabric with some limit in terms of luster properties. One of the interesting fabrics showing subdued luster is the velvet fabrics with dark shade. In this study, the luster related properties are examined using some image analysis methods. Yarn models based on the fabric weave types were developed to further investigate the effect of fabric crimp shapes due to weave on the optical properties or luster of the fabrics.

The purpose of this study was to investigate the dyeability and color fastness of cotton and silk fabrics dyed with extract of Arrowroot leaf princeps. The experimental items were divided into the mordant treatment, component of fabric and kind of mordants. The experimental study was done by laundering, abrasion(dry/wet), perspiration(acid/alkali), light fastness, color difference by C.C.M system and K/S test. The summerized finding reulted from experiment and investigation are suggested as follows : In the C.C.M and K/S test on mordanting method and kind of fabric, that of silk and cotton was the most effective in the pre mordant treatment. In the C.C.M and K/S analysis on 5 mordants, that of silk and cotton was significantly improved when mordants was treatmented. Especially, that of Fe mordanting treatment was higher than Al, Cu, Cr and none. In color fastness on mordants, laundering, perspiration and abrasion fastness showed 4-5 grade but light fastness showed 1-3 grade.

The purse of this study was to invesigate the dyeing fastness on extract of bufferbur leaf princeps. The experimental items were divided into the mordant treatment, component of fabric and kind of mordants. The experimental study was done by laundering, abrasion (dry/wet), perspiration (acid/alkali), light, iron fastness test and color difference by C.C.M system. The summerized finding resulted from experiments and investigation are suggested as follows : In the C.C.M test on mordanting method and kind of fabric, color difference of silk was three times higher than cotton. The silk fabric was the highest in simultaneous mordant treatment but cotton fabric was the highest in none mordant. In color difference analysis on 6 mordants, that of silk and cotton was significantly improved when mordants was treatmented. Especially color difference of Fe and Cu mordanting treatment was higher than Cr, Sn, Al and none. In dyeing fastness on mordants laundering, perspiration, abrasion and iron fastness showed 4-5 grade but light-fastness showed 1-3 grade.

Cochineal dyeing was applied to natural fiber fabrics, cotton and silk fabrics, and synthetic fiber fabrics, nylon and polyester fabrics. Chitosan-pretreatment was applied to the fabrics in order to investigate the effect of chitosan treatment on the dyeing behavior. The effect of chitosan treatment on the mordanting was also investigated by incorporating Cu-mordant on the chitosan-treated or chitosan-untreated fabrics during the dyeing process.

The purpose of this study was to investigate dyeing properties and antibacterial activities of cotton and silk fabrics treated with Ginkgo biloba leaf extracted with three kinds of aqueous solvents: distilled water, electrolytic reduction water and electrolytic oxidation water. The optimum dyeing condition of Ginkgo biloba leaf was 120 min at 8$0^{\circ}C$. Electrolytic reduction water had the highest dyeability to both cotton and silk compared with electrolytic oxidation water and distilled water. A color of extract by distilled water and electrolytic oxidation water showed yellowish Yellow Red, extract by electrolytic reduction water showed reddish Yellow Red. Irrespective of kinds of extraction solvents, appropriate acidity of medium was pH 9∼11 and pH 3 for cotton and silk fabrics, respectively. Colorfastness to laundering and Light fastness showed generally low but crocking fastness was excellent. Antibacterial activities of the treated fabrics above were 99.9%.

1. The blended tabby whose warp and weft each employs a different kind of thread had been weaved since the era of the Three Kingdoms in this nation and since the period of Han in China. Especially in the 15th century. very finely weaved fabrics as the specialty of Chosun were exported to China. In the 16th century. blended tabby weaved with silk and cotton were often used for clothes as cotton was produced around the nation. And in the 17th century. blended tabby employing high quality Chinese raw silk other than existing ones were weaved. 2. It has been found in literature review that Honpo, one of Chosun's blended tabby. was manufactured mainly in Hamkyung, Cholla and Kyungsang provinces and mostly distributed through markets of Chungchong and Cholla provinces. 3. Out of the total 19 fabric pieces. 13 employed silk thread as the warp and cotton thread as the weft. Compared with the weft. in general. the warp is given more tension when weaved and more friction by spindles, being more likely to be twisted than the weft. In addition to starching, a stronger thread is requested as the warp. It is natural that in the Chosun period, silk thread more stronger than cotton thread was used as the warp to make more durable fabrics. For the weft requiring lots of threads when weaved. cotton thread was mainly used in the 17th century because the thread could be easily obtained at that time. 4. So far the study has made an empirical review of Chosun's blended tabby. especially those of the 15th∼17th century, in terms of their production and distribution. Findings from the study have some limit because they have been made focusing on the 15th∼17th century not the whole period of Chosun. Therefore it is needed to complement those findings through further studies.

We exanmined the each effect of $NO_2$ and $SO_2$gas, the maincomponets of air pollutants, on the deterioration of 6 organic materials with Gasexposure cabinet. The organic materials were used 2 kind of papers(Korean paper, Oldbook paper) and 4 kind of textiles (Cotton, Silk, Hemp, ramie) in gas exposure experiments. In order to know how to change of physical conditions, the materials were exposed to 2000, 1000 ppm. h of $SO_2$dose, to 100 ppm. h of $NO_2$ dose at 65% RH. The color difference, tensile strength, elongation coeffient, mass reduction and fabric status of each materials were discussed the following below.1. The color difference of cotton and hemp was larger than that of silk and ramie in the presence of $SO_2$ gas. and the color difference of korean paper was less than that of the textile materials in the presence of $SO_2$ gas.2. The tensile strength of cotton fell suddenly at 100ppm.h of $SO_2$ dose and even became 56% of the unexposed cotton.3. The weight of 6 materials began to decrease in the presence of $SO_2$ gas.4. The tensile strength and elongation of the materials tended to decrease at 12.5ppm.h of $NO_2$ especially silk was the strongest tendency to decrease.5. Cotton, hemp and ramie were influenced by $SO_2$ gas more than by $NO_2$, but silk were influenced by $NO_2$ more thang by $SO_2$ at 10ppm.h of each noxious gas.
