  • Silk fabric was sputter-treated with Au, Cu, SUS, and Ti using poly(vinyl alcohol) (PVA) as a binder, and its changes in color, antielectrostatic property, airpermearbility, and rubbing fastness were investigated. Sputter-treated silk fabric had a natural color of metal target, which was deepened by treatment of PVA solution. The rubbing fastness of thin metal layer formed by sputtering was improved by PVA treatment. Au had highest rubbing fastness among the metal targets. In addition, PVA treatment posterior to sputtering resulted In higher rubbing fastness than the other treatment method. However, a reverse trend was found in antielectrostatic property. Air permeability of the sputter-treated silk fabric was improved by PVA treatment, which was highest when sputtering was conducted prior to PVA treatment.

  • The fabric, 100% Silk, was dyed with Atractylodes japonica extract solution. The effects of concentration of extracts (colorant), temperature of dyeing, time of dyeing and pH of dye bath were studied. As the concentration of extracts increased, color strength (K/S value) increased progressively. The K/S values increased with raising temperature, time and proper conditions were $80^{\circ}C$ and 80 minutes. Maximum K/S value was obtained at pH 3. The K/S values of mordanted fabrics were increased with increasing mordant concentration up to specific values. Surface color of dyed and mordanted fabrics were yellowish. Light color fastness of fabric with mordanting was fairly good 3/4 rating. The mordanted silk fabrics showed excellent antibacterial activity. The silk fabric dyed with Atractylodes japonica extract showed a superior UV protective property.

  • This study examined textiles used for the ancient costumes that are excavated from tombs of the Chosun dynasty, focusing especially on Po(overcoat). The result of the study is that silk occupies 79.8% of all the textiles used for Po, and cotton and linen follow. The weaving method of silk was primarily plain and satin weaves. However the use of twill, gauze, and double weave, that had led weaving methods of silk during the Koryo dynasty, are considerably decreased in Chosun dynasty. Danlyeong(단령) and Cheollik(첩리) had been made of various textile fabrics like cotton, linen, silk and blended fabric before Imjinwaeran(임진왜란). After the war, they were simplified in gauze weaved silk or satin weaved silk, And also patterned fabric were widely used for them than other Po. Simple fabrics like cotton, linen and plain weaved silk had been used for Aekjureum(액주름) and Jiklyeong(직령) before Imjinwaeran. After the war, Jiklyeong was used as underwears of Danlyeong, so it was made of high quality patterned silk. Dopo(도포) and Changuiryu(창의류) were mainly excavated from tombs after the war, high quality plain weaved silk are used than gorgeous Patterned silk. For the Dopho(답호) and Bansuui(반수의), before the war, they were made with various textiles such as plain weaved silk, twill weaved silk, satin weaved silk, cotton, linen, and blended fabric. But after the war plain weave was mainly used. In Jangui(장의), since it was mostly for women, many kinds of women's patterned silk were used in than any other Po. There were only a few excavation of Simui(심의) and most of them were made of ramie and were hemmed in black satin without pattern.

  • Dyeing process of the natural indigo powder onto ramie and silk fabrics was investigated by using glucose and calcium hydroxide as a reducing system. Effect of reduction and dyeing conditions such as temperature and time of reduction/dyeing, and concentrations of glucose and calcium hydroxide on the dyeing process were explored. Indigo powder was obtained by drying the conventional niram paste in an oven at $50^{\circ}C$. Color strength of the dyed fabrics was evaluated by K/S value measured at the wavelength of maximum absorption(${\lamda}$max). Munsell color coordinates(H V/C) were used to compare fabric colors of ramie and silk. Ramie fabric showed purple-blue color for all the temperature and time. On the contrary, silk fabric showed wide range of color including brown, brown-green, green at the different temperature. With the increase of K/S value, the coordinate of value(lightness) decreased for both of ramie and silk fabrics. The coordinate of hue(shade) changed drastically with the increase of K/S value for silk fabric, compared with that of ramie fabric which showed nearly constant value at the whole range of K/S value. Optimum concentrations of calcium hydroxide were for 6 g/L for ramie and 4 g/L for silk at $60^{\circ}C$ and 50 min. K/S value increased with the indigo concentration. Maximum K/S value was shown at $10{\sim}12$ g/L of glucose concentration. For both of ramie and silk fabrics, the colorfastness of washing and light was lower than that of rubbing. All the colorfastness values were improved with the increase of color strength.

  • Antimicrobial activity of silk and cotton fabrics dyed with gromwell colorants was examined by shake flask method. The effects of bacterial reduction rate on dye uptake and mordanting were explored. The silk(K/S value 8) and cotton fabric (K/S value 4) dyed with gromwell colorants showed high bacterial reduction rate of 99 % and 88 %, respectively. Post-mordanted silk fabric increased at K/S value, also showed higher bacterial reduction rate than unmordanted. But the effects of antimicrobial activity on mordants showed respectively different results. Pre-mordanted cotton fabric except Sn mordant increased at K/S value, but it was not significant. Pre-mordanted cotton fabric showed significantly higher bacterial reduction rate than unmordanted. Therefore, it was considered that dye uptake of cotton fabric dyed with gromwell colorants and mordants were involved in the bacterial reduction rate. It was concluded that gromwell colorants had antimicrobial activity.
