  • This research from analyzing dyed silk fabrics treated with persimmon juice by padding concludes as follows : The add on is increased as the number of padding increase and the color of the dyed fabrics holds red-yellow colors which has low brightness and high chromatic colors. The fabrics dyed with persimmon juice have properties such as 2nd grade of light fastness, 4~5th grade of perspiration fastness and rubbing fastness, and 3~4th grade of washing fastness. The dyed fabrics exposed to UV light have deeper yellow-red color than things exposed to sunlight. The silk fabrics treated premordants have shown strong yellow colors, especially the fabrics added Fe mordant have shown greenish red-yellow colors. As the padding times of dyeing with persimmon juice are increased, strength and water-repellent property are enhanced along warp and weft direction respectively but anti-crease property is decreased. Also, the dyed fabrics have good antibacterial activity and deodorization.

  • This study was executed to substitute Carbon-arc method, which is a method currently used for testing light-fastness of military textile products, with Xenon arc method. Specimens used in the study were classified according to the fabric material and color of military textile products and were composed of 11 items of 42 kinds with different colors. Light-fatness test was done by comparing the result of Carbon-arc(KS K 0700) and Xenon arc(KS K ISO 105-B02) method. In Xenon arc method, blue wool reference materials of 1~8 was used, and exposure condition preferred in American continent and light exposure method 3 were applied. After testing with both methods, grade of light-fastness, color difference, reflectance and color were examined. Even though there was a slight difference among 42 specimens used in the test, results exceeded the quality standard both in Carbon-arc-lamp and Xenon arc-lamp. Therefore, it was confirmed that applying KS K ISO 105-B02 together in the KS K 0700-regulated Ministry of National Defense standard and purchase order would also fit.

  • In this research, the curly dock was used in the process of dyeing for fabrics of the inner wear & the patient wear. Since the curly dock has a pharmacological effect on dermatosis, this study focused on the variety of color and functions of the inner wear fabrics & patient wear fabrics to make the best use of the pharmacological effect of curly dock. With regards to giving a variety of colors and functions in the inner wear, patient wear fabrics, the curly dock dye was used in each treatment conditions on the cotton & silk fabrics. After dyeing, the dyeability, color change, light fastness, washing fastness, perspiration fastness, antibiosis, far infrared emissivity and emission power were evaluated. The evaluation results are as follows; The dyeablity increased from repeated dyeing and, by using the mordant, variety of colors such as skin, mustard, greyish-brown and dark earth colors were conformed to the naked eye. Fe mordant was better than Al on the lightfastness and the washing fastness. The repeated dyeing was found out to have less effect on neither lightfastness nor washing fastness. Both silk and cotton fabrics were graded $3{\sim}4$, since their degree of degradation appeared to be the same in alkali perspiration and acidic perspiration. In the case of silk fabrics mordanted by Al, the rate of declining in both Staphylococcus aureus ATCC 6538 and Klebsiella pneumonia ATCC 4352 were 99.9%. In addition, the antibiosis was enhanced when the mordant was used. The far infrared was 86.6% of emissivity, $3.34{\times}10^2\;W/m^2{\cdot}{\mu}m$ emission power.

  • This study was carried out the effect of stability and color extract for it's condition in the curcuma L.. dyeing. The stability is to investigate the absorbance of the curcumin, one of the major yellow pigments and the stability regarding the effect of light, oxygen temperature and pH. The dyeing condition is compared the effect of mordanting condition and the best way to extract pigment and analysed through the color-fastness rating, color-difference value test. The main results obtained are summarized as follows ; 1.The best and proper solvent to extrect curcumin pigment was a ethanol and a distilled water. 2. The light effect indicated that the absorbances of solution in absence of ligh was more stable. 3. The oxygen(O2) effect to curcumin show-ed that the condition in the absence of O2 was more stable than that in presence of O2 4. The temperature showed that the absorbnace was best stable in4$^{\circ}C$ and less changed at $25^{\circ}C$ 5. The curcumin-etanol solution was stable in pH 2~4. 6. Generally color-fastness rating to silk, wool and cotton indicated that crocking C.F. and perspiration C.F. were more than 3rd grade and dry cleaning C.F. was more than 4th grade. But light color-fastness and washing color-fastness were very poor. 7. To make good color fastness, the mordan-ting treated group and the pre-mordant conditions were more effective than others 8. When compared with color-difference value test indicated that the silk was looks like more reddish and bluish color and than the wool and cotton were greenish and bluish. As a mordant, A(C2H4OH(COOH3) and D(K2Cr2O7)were more effective to make green-ish color in the silk and the reddish color was abtained by B(Al.K(SO4)2.12H2O) and C(FeSO4.7H2O).

  • The experiments about dyeing concentration, temperature and time were done using yellow, red and purple loess as natural inorganic dyes in order to verify a degree of dyeing, characteristics of color and fastness. The results were as following; 1. As a result of analyzing components of loess, purple loess was much than other loess in quartz component and coarse particles contained. This affected to the degree of dyeing. 2. The stronger dyeing concentration was, the more the degree of dyeing was improved, and yellow loess containing fine particles was the best in the degree of dyeing. 3. When it was dyed with raising up to $100^\circ{C}$ for 10 minutes after stirring for 20 minutes at $60^\circ{C}$, was better than on starting at $40^\circ{C}$ or $80^\circ{C}$ in the degree of dyeing. Also yellow loess was the best in these experiments. 4. Washing fastness of loess was low such as other natural dyes, but dyeing wasn't transferred to other textiles. On the other hand, light fastness of it was very excellent and rubbing fastness was relatively good as 3~3.5.

  • Functional properties are available with sputtering. But sputtering treatment alone cannot got a good fastness performance to washing, rubbing and light. This research was objected to investigate optimum condition by sputtering on polyester through various processing conditions such as ion current and treatment time, and then various resin treated onto metal coated polyester fabrics in order to increase washing fastness of metal membrane. As the results, the optimum conditions revealed 1500 mA of ion current, 2 min of treatment time in sputter, and suitable resin concentrations were 2% of o.w.s (on the weight of solution) in resin treatment. Therefore, we could get enhanced anti-static effect and flex stiffness as well as washing fastness in sputtered polyester fabric with various resin treatment, for example, melamine and polyurethane.
