  • This study examines the mordanting effect and multi functional properties of silk fabrics dyed with onion shell extracts that were mordanted with gallnut. The contents of this study are as follows. First, the optimum dyeing conditions were investigated by measuring the K/S value that depended the on dyeing conditions when silk fabrics were dyed with onion shell extracts. Second, the color, brightness, and chroma differences that appear after mordanting with gallnut were investigated by measuring the K/S and Munsell value. Third, the color fastness and antimicrobial activity were measured. When silk fabrics were dyed with onion shell extracts, the optimum dyeing conditions were a dyeing temperature of $70^{\circ}C$, a dyeing concentration of 160%, and a dyeing of time 30min. After mordanting with gallnut extracts, the K/S value increased remarkably and was larger in pre-mordanting than post-mordanting. The H value displayed yellow-red in all cases of pre and post mordanting. However, the H value was more reddish in the order of non-mordanting

  • The purpose of this study was to investigate the dyeability and antibacterial activity on wool fabric dyed with cochineal at variable dyeing conditions. Al, Cr, Fe, Cu and Sn were used as mordants and adsorption was compared with different mordanting methods. The optimum dyeing conditions of wool fabrics were dyeing concentration 2.0%(o.w.s), dyeing temperature $60^{\circ}C$, pH 3 and dyeing time 30 minutes. The pre-mordanting method was preferred for Al and Cr, and the post-mordanting one was preferred for Cu, Sn and Fe to achieve better dyeing. The optimum mordanting conditions of wool fabrics dyed with cochineal were mordanting concentration of 1%(o.w.s), mordanting temperature $60^{\circ}C$, and dyeing time 30 minutes. Wool fabrics dyed with cochineal showed a little antibacterial activity, but it was increased by Cu and Sn mordanting. The light fastness and perspiration fastness of wool fabric treated with cochineal were improved by mordanting.

  • Based on the previous study, three types at synthetic fibers comprising nylon, PET, and acrylic fibers were investigated in this study. The effect at mordanting on the air-permeability and dyeing properties at fabrics was investigated. The effect at rinsing process on the air-permeability and color was quantitatively investigated by rinsing the mordanted fabric specimens 1$\sim$3 times after mordanting. The air-permeability changed peculiarly according to the characteristics of the tiber materials after mordanting. The air-permeability values of nylon and acrylic fabric specimens dropped significantly after mordanting. On the other hand, those of PET fabric specimens hardly changed after mordanting. The metal ions absorbed on the fibers of nylon and acrylic fabrics did not show the mordanting effect. Regardless of mordanting, cochineal dyestuff made direct links with the molecular chains in nylon fabrics exhibiting dark colors. After dyeing acrylic fabrics, the color did not develop at all, even though partial components of the cochineal dyestuff were absorbed apparently.

  • In order to analysis on color difference of natural dyes, I have dyed Hanji, cotton, silk fabric and exposed them to carbon arc light. The results of experiment have been analysed by Munsell's value, and compared the difference of colors which were recognized visually. Gardenia Jasminoides is monogenetic dye, but it gained darker color by pre-mordanting method used aluminum mordant agent and greenish yellow color by ferric mordant agent. whereas Curcuma, an Amur cork, and bud of pagoda tree are shown as greenish yellow color, and A barberry root, Betel nut, and Rhubarb are shown as reddish yellow color. these gained khaki colored dyed fabric by ferric mordanting. In addition, Sappan wood showed great result in pre-mordanting. Especially, it gained dark red color by aluminum pre-mordanting. The pink color was shown by post-mordanting. and Logwood showed great dyeing result in Hanji and cotton better than silk. Specially pre-mordanting was effective. Hanji and cotton showed greenish blue color by aluminum pre-mordanting, and silk showed brown color. However the color, which was recognized visually, differed from colorimeter sometimes. Therefore, such color table might be necessary for the natural dyeing.

  • In order to study the effect of mordanting on silk fabrics treated with tannin, those fabrics were treated with Al, Cu, Cr, Fe, Sn by pre and post mordanting. It was studied about color change, weighting effect, dgree of photodegradation by pre and post mordanting. The results are as fallows ; 1. On the addition of mordants into mimosa and tannic acid solution, &{\lambda}_{max}& of the former was slightly blue-shifted, on the other hand, &{\lambda}_{max}& of the latter was obviously Red-shifted. 2. In case of Cu, Cr, Pre mordanting, weighting effect were appeared. Weighting effect of silk fabrics treated with Tannic acid increased higher than mimosa by mordanting. 3. In color change, Silk fabrics treated with Mimosa and Tannic acid generally changed to red direction and fabrics treated with tannic acid changed to yellow direction by pre and post mordanting. 4. In the photodegradation, the degree of photodegradation on mordanted fabrics increased. Its degree was slack in Cu, Cr, Post mordanting. On the other hand, Al, Fe, Sn were greate. Silk fabrics treated with Mimosa and Tannic acid got inhibiting effect on photodegradation.

  • To obtain a full range of colors on cotton, wool and silk fabrics with natural dyes, mordanting and combination dyeing were carried out. Tannic acid and metal compounds containing copper, tin, iron, nickel, chrome and alum were used as mordanting agents. Palmatin, red wood and natural indigo dyes were used as the three primary colors for combination dyeing. After mordanting, the colors of fabrics dyed with natural dyes changed. In combination dyeing of palmatin/red wood and palmatin/natural indigo, the two component natural dyes showed good miscibility in dye bath and various colors were obtained according to the content of dyes used. In combination dyeing of red wood and natural indigo, the various colors were not obtained due to gelation in dyebath. This problem could be solved by dyeing with indigo, mordanting then dyeing with red wood. Violet color was obtained by alum mordanting and gromwell dyeing. The expansion of color range of natural dyes by mordanting and combination dyeing has been demonstrated.
