Dansam (Salvia miltiorrhiza Bunge) is a perennial plant that belongs to the Labiatae family and is characterized by red pigment found in the epidermis of its roots. Research on the dyeability of Dansam extract was performed with repeated trials under various conditions such as temperature, time, and mordant treatment. Silk fabrics were dyed with Dansam extract and mordanted with various agents such as Al, Fe, Cu, and Sn to evaluate the dyeability and functionality of Dansam extract; subsequently, the K/S value and the change of surface color were analyzed using a colorimeter. In addition, the dyeability of dyed fabrics (such as color fastness to washing, dry cleaning fastness, rubbing fastness and light fastness) and functionality (such as antibacterial activity and deodorization) were analyzed. The surface colors of all dyed fabrics were recorded and the results showed the presence of mostly YR series of colors; in addition, a GY color series appeared in the Fe pre-mordants of the silk fabric. The highest K/S values were recorded in Fe post-mordants. The washing fastness were Level 3 and Level 4; in addition, the dry-cleaning fastness showed excellent results at Level 4 and Level 5. The rubbing fastness was satisfactory at Level 3 and Level 4 and the light fastness was satisfactory at Level 4. The results of the measurements (that pertained to the antibacterial activity of fabrics dyed with Dansam extract) showed a 99.9% bacteria reduction rate of Staphylococcus aureus and Klebsiella pneumoniae. In regards to deodorization ability, dyed fabrics were found to have higher deodorization rates than those not dyed. The dyed fabric demonstrated exceptional deodorization qualities.

This study purposes to find the best one for dyeing with artemisia in order to develop a more efficient method of dyeing with artemisia and investigates the antibiotic activities of artemisia. After dyeing cotton, rayon, silk, wool and nylon fabrics with dyebath extracted from artemisia, observation on dyeability by temperature, concentration and time has been carried out. And I took an observation on color change, color fastness to washing and color fastness to light after mordanting treatment. Also observation on the antibiotic properties of non-dyed fabrics, artemisia-dyed fabrics and artemisia-dyed fabrics with post-mordant has been performed to investigate the antibiotic activities of artemisia. And the following results have been obtained. 1. The dyeability of artemisia was better for protein fabrics such as silk or woo and amide-based synthetic fabrics like nylon than for cellulose fabrics such as cotton and rayon. 2. For all tested fabrics, the dyeability was increased as the concentration of artemisia dyebath, dyeing time and dyeing temperature was increased. Especially the dye ability for protein fabrics was most affected by the temperature, and high dyeability was obtained at high temperatures. 3. For the color fastness of artemisia-dyed fabrics with mordanting treatment, the color fastness to washing was good with grade of 4-5 while the color fastness to light ranged from grade 2 to grade 3, which requires improvement for practical use. 4. The artemisia-dyed fabrics were shown to have much higher antibiosis than the non-dyed fabrics, and the artemisia-dyed fabrics with mortanting treatment showed the following result; Cu 99.9%, Al 64% and bittern 64.7%.

This study was carried out to identify the optimum dyeing conditions for maximum dye uptake of Prunus yedoensis Matsumura flower extract on silk fabric and to investigate hue/tone characteristics and fastness properties of the dyed fabrics. As results, the flower extract was found to contain flavonoids by FT-IR and to show yellowish shade by UV-vis spectrum. Silk fabric was optimized for maximum dye uptake to five repetitions of dyeing at $80^{\circ}C$ for 60 min with an extract concentration of 600% owf in terms of both K/S and color differences. Pre-mordanting was more effective to dye uptake than post-mordanting for all of the mordants used. Un-mordanted and pre-mordanted fabric showed YR(Yellow Red) while most of post-mordanted ones did Y(Yellow). Main tones of dyed fabrics were sf(soft) and lt(light) in the case of unmordanting or Al-mordanting whereas they were d(dull) and g(grayish) by post-mordanting with Cu, Cr, and Fe, respectively. The fastness grades to rub and dry cleaning were reasonably good for most dyeing conditions while those to light were poor. Finally dyeing condition for each hue/tone of the dyed silk with the flower extract was optimized considering fastness properties.

The pine needles can be used for four seasons in normal living and it can be taken friendly everywhere as it is distributed over 50% in Korea. The pine needles consist of vitamins, protein, minerals, essential oil and enzyme related to antimicrobial activity. It has effect like high blood pressure, neuralgia and hanged over by terpene, glucokinin, rutin, apigenic acid and tannin. Also the extract of them can be used for dyeing of fabrics. However, the extract components and effects of them are not well known yet. Therefore, the purpose of this study was to investigate the volatile components of the pine needles extract and functionality. The pine needles extract was dyed into various fabrics(nylon, silk, wool and soybean) and mordanted with Al, Cu, Cr, Fe and Sn. The extracted aroma compounds were compared by gas chromatography-mass spectrometry. The major volatile compounds of pine needles verified by using SPME were alpha-pinene, beta-pinene, beta-phellandrene, caryophyllene, ethanon, benzen. A total of 15 compounds were identified by using the SPME fibers. In the UV-visible spectra, the maximum absorption of wavelength of the pine needles ethanol extract appeared at 460, 630nm for chlorophyll component and at 237, 281nm for tannin component with the pine needles distilled water extract. Most of sample showed high antibacterial effect in none mordant but wool fabric showed high antibacterial effect in mordants. The result of UV block test showed a superior ability of blocking ultraviolet ray infiltration in all sample.

In this study, the dyeing properties of Phellodendron amurense on cotton and silk fabrics were evaluated to establish a scientific database of dyeing methods using natural dyes with the ultimate aim of facilitating the practical use of these dyes. The optimal thickener and dyeing concentrations depending on the thickener type were identified when dyeing with P. amurense, and the fabric color, color fastness, and antibiosis were examined for various thickeners, fabrics, and mordants. The results were as follows.: The optimal concentrations of thickeners when dyeing on cotton and silk fabrics were CMC 3% (w/w), Mayprogum 7% (w/w), and Indalka 9% (w/w). The optimal concentration of P. amurense was 25% (w/w), irrespective of the type of thickener. To maintain the hue unique to P. amurense, thickening with Mayprogum or Indalka and mordanting with Al was effective for cotton, while thickening with Mayprogum or Indalka and mordanting with Al or thickening with CMC and mordanting with gallnut was effective for silk. The dry-cleaning fastness and abrasion resistance of cotton fabrics dyed with P. amurense were excellent at the 4-5 level. Gallnut was effective for washing fastness and perspiration fastness against color degradation, and FFC was effective for light fastness. The washing fastness, dry-cleaning fastness, abrasion resistance, and perspiration fastness of silk fabrics dyed with P. amurense were excellent at level 4, except for washing and perspiration fastness, and FFC was effective for the improvement of light fastness. Dyeing cotton and silk fabrics with P. amurense thus yielded antibiosis and excellent washing fastness.

The study that has been conducted is the consideration of the durability of dye, antibacterial activity, and deodorizing effects of cotton and silk textiles dyed with a botanical dying material that has been used in various ways over the years as Korean diet and folk remedies, the pomegranate. 1. The results of the K/S value of dying according to the types of mordants of textiles dyed with pomegranate extract the following have been discovered: The increase of K/S value of dying of the silk textiles appear to be higher than that of the cotton textiles. Next, silk textiles that have been treated with FeSO$_4$.7$H_2O$ appear to be at the highest. 2. The results of the color change measurement show a difference of color can be noticed according to the types of mordant. As opposed to those textiles that had been only scured textiles, all of the dyed textiles appeared to turn yellow. 3. Textiles that had been treated with $K_2$Cr$_2$O(sub)7 recorded the highest durability according to the colorfastness to light results. In the case of the cotton textiles colorfastness to washing, all appeared to show exceptional results of 3rd class or higher, excluding the textiles that had been treated FeSO$_4$.7$H_2O$. However silk textiles recorded relatively low classes of below 3rd to 4th class. For the colorfastness to washing of pollution, the results for both the cotton and silk textiles were excellent at class 4-5. The results of colorfastness to perspiration, colorfastness to rubbing, and colorfastness to dry cleaning showed comparatively exceptional results of 3rd to 4th class or higher when it came to dyed textiles. 4. According to the measurements of antibiosis, dyed textiles that had been treated with SnCl$_2$.2$H_2O$ appeared to show an exceptional bacterium decrease of approximately 70%. 5. According to the deodorizing measurements, dyed silk textiles appeared to have a higher deodorizing effect than cotton textiles. As for cotton textiles, those that had been treated with FeSO$_4$.7$H_2O$ and in the case of dyed silk textiles those that had been treated SnCl$_2$.2$H_2O$ recorded the highest deodorizing effect.
