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 made to investigate the effects of mimosa tannin and tannic acid on change of properties and photodegradation of silk fabrics according to tannin concentration and irradiation time. The results were as follows. 1. As concentration of tannin increased, thickness, fabric count and stiffness showed no difference. But tensile strength were increased, and elongation were decreased. 2. When concentration of tannin is high, tannin adhered to surface of fabrics. 3. fR absorption bands of untreated silk fabric appeared at $3400cm^{-1},\; 1640cm^{-1},\;1445cm^{-1},\;1235cm^{-1},\;and\;675cm^{-1}$, but those of silk fabric treated with tannic acid appeared at $1710cm^{-1}\;and\;3400cm^{-1}$ by treatment of mimosa tannin, respectively. IR absorption bands of photoirradiated silk fabrics appeared at $3400cm^{-1},\;3280cm^{-1},\;2960cm^{-1},\;2920cm^{-1},\; 1720cm^{ -1},\;1380cm^{-1},\;1280cm^{-1},\;1120cm^{-1},\;and\;1070cm^{-1}$. But those bands were decreased at the silk fabrics treated with mimosa tannin and tannic acid.

Silk Industry doesn't have enough strategic ability to plan the product for internal and external strong competition and global luxury trend in Jinju. To provide silk fashion planning information and planning method, this study investigated the fabric planning system, such as product system and problems, the method of seeking information, via questionnaires for 68 Jinju silk companies. The results were that the Korean traditional garment, Han-bok and lining of that were given more wight in Jinju Silk for domestic, and the next, neckties. These silk had produced by OEM and didn't have almost my planning ability, but nowadays buyers wanted to get some planning ideas from manufactures, not giving any planning guideline before production, more and more. For Jinju Silk Fabric Companies, planning direction of silk fabrics of vision were needed, that had to be adaptable to manufacture situation and applicable to market.

The purification, dissolution and powdering of stained waste silk obtained from weaving and dyeing process were studied for the surface modification of textile fabric and plastic materials. The whiteness of stained waste silk could be improved through degumming and bleaching with sodium hydrosulfite. The water-soluble fibroin solution can be obtained by dissoving the degummed waste silk in a boiling solution of 50% calcium chloride for 60 minutes. The salts and heavy metals contained in fibroin solution were removed by electric dialysis, wool fiber filtration and gel filtration chromatography. The fibroin powder was prepared by using a fine grinder after the alkali treatment for weakening the silk fiber. The fine fibroin powder of particle size around 30 ㎛ was obtained with a ultra fine-mill, while it was finer below 10 ㎛ with a ball-mill. The dissolved or powdered silk was applied to the surface of fabric with addition of the binder (a urethane resin). The moisture content of polyester and nylon fabrics treated with the silk solution was improved due to hygroscopic property of silk. The fine fibroin powder mixed with the binder ws coated on the surface of synthetic film by use of the air pressed sprayer. It was revealed that the hygroscopicity as well as the softness of fibroin powder coated film was much improved. Therefore, it is thought that the fine silk fibroin powder is applicable as an coating agent for the surface modification of plastic and synthetic leather.

몇 종의 식물자료에서 추출한 염액으로 견을 염색하여 색채를 조사하고 염색견에 3종의 매염제처리를 한 후 세탁 및 내광견도를 조사한 결과는 다음과 같다. 1. Tannin계 및 뽕나무뿌리로 염색한 견포의 색채는 연한 다색계통이었으며 염색견포에 황산동 및 황산제일철로 매염처리하면 색상(Hue)은 염재의 종류에 따라 각각 다르게 변화되었고 명도 및 채도(V/V)는 모두 감소되었다. 2. Tannin계 및 뽕나무뿌리로 염색한 견포에 황산동 및 황산제일철로 매염처리하면 미매염견에 비하여 세탁견도가 1급내외 향상되었고 매염처리견의 자외선조사에 의한 dye-loss율이 미매염처리 견보다 크게 감소되어 내광견도가 향상되었다.

Dyeing properties of silk fabric with onion shell were studied by investigating the effect of dyeing conditions, such as concentration of onion shell, dyeing temperature, dyeing time and pH, on dye uptakes. And also the effects of mordants and mordanting methods or color change and dye uptakes were investigated. For the practical use, the various color fastness of dyed and mordanted fabric were evaluated. The color fastness was improved when Fe mordant was added.

We prepared natural indigo/calcium hydroxide complex powder from tinctoria's leaf, according to the demand of developing new dyeing technique of natural fibre with natural indigo. FT- IR and UV/Visible spectra were operated to find the dyeing properties of synthetic indigo and natural indigo powder. Cotton, flax and silk fabrics were dyed with different pH, dye concentration and dyeing time. The colour yield of indigo dye was quite sensitive to dye bath pH and fabric. In synthetic indigo, the highest K/S value of dyed silk fabric was shown at near pH 9.0, and which of flax and cotton fabric were shown at pH 11.0. In other hand, in the case of natural indigo complex powder, the highest K/S value of dyed silk fabric was shown at near pH 8.0, and which of flax and cotton fabric were shown at pH 9.5∼pH 10. Mercerized cotton fabric dyed with natural indigo powder has a little antimicrobial activity.

This study was conducted to suggest the best union fabric to combine with cellulose fiber for summer and in-between seasons. Four types of union fabric, viz. silk/flax, silk/cotton, rayon/flax and rayon/cotton, were used as sample fabrics after weaving them in a local textile factory. The air permeability, moisture regain, water absorption, water vapor permeability and thermal insulation of the samples were tested. The results are as follows. The rayon/flax union fabric is the most suitable for summer clothes due to its having the best comfort property of air and water vapor permeability, and moisture and water absorption. For in-between seasons, it is recommended to use the silk/cotton union fabric because of its good thermal insulation properties.

The Silk fabric was dyed with various acid dyes, and than treated with copper sulfate or copper sulfate/thiourea. Munsell color system, dye exhaustion and light fastness were investigated for the treated fabrics. The results obtaind are as follows: 1) The color variation of the silk-dyed fabric by aftertreatment with copper sulfate was shown redish, but original color with copper sulfate/thiourea. 2) Copper sulfate/thiourea was much more effective than copper sulfate only to increase the light fastness. 3) The crease recovery was increased by aftertreatment with copper sulfate/thiourea. 4) Dye exhaustion and tensile strength of the silk-dyed fabric by aftertreatment with copper sulfate was decreased about 8-15% more than those of untreated.

Silk fabric was dyed using methanol extract of Chrysanthemum boreale at $60^\circ{C}$ for 40min. The K/S value of the silk fabric was highest in the premordanting method, while the amount of absorbed mordant was largest in the Cu-mordanting. The surface colors of the dyed fabric highly depended upon mordants or mordanting methods. For all cases, the value of the dyed fabric was dark. The chroma was high by using the Cr-mordant and the color difference was distinct by using the Fe-mordant. Cu-mordanted silk showed highest fastness to light. Dyed silk fabrics by mordanting method showed good antimicrobial activity ad deodorization property.
