This study investigated the dyeability and color change of the natural dyes of SeaCell, a biodegradable functional fiber that is permanently added to cellulose fibers with natural additives extracted from seaweeds. The natural dyes used in the study are five dyes. Gardenia and turmeric, which are yellow-based natural dyes, Sappan wood and Lac, which are red-based natural dyes, and Indigo, a blue-based natural dye, were selected. The dyeability and color change according to the change of the mordant conditions and the number of times of dyeing were investigated. In addition, the dyeing properties and colors of cotton and silk fibers were compared under the same dyeing conditions as SeaCell. The study results are as follows. It was found that SeaCell had lower dyeing properties than silk, a protein fiber, in gardenia, sappan wood, and lac dyes, but had higher dyeing properties than cotton with the same cellulose component as SeaCell fibers. In the case of turmeric, it showed higher dyeing properties than cotton except for the no mordant condition. In the case of Indigo dye, SeaCell shows the best dyeability, indicating that it is a very suitable fiber for Indigo dyeing. As sustainable functional fibers are continuously developed in the future, natural dyes that are environmentally friendly and human-friendly are actively introduced and commercialized, and it is expected that they can be used as reference materials.

The purpose of this study was to investigate the colorfastness of cotton and silk fabric dyed with extract of Lotus leaf princeps. The experimental items were classified into mordanting treatments, fabric components and kind of mordants. The experimental test was done by laundering, abrasion(dry/wet), perspiration(acid/alkali) , light fastness, color difference by C.C.M(computer color matching) system and K/S test. The summarized findings resulting from the experiment and investigation are as follows: In the C.C.M and K/S test on mordanting method and kind of fabrics, co-mordanting treatment method and protein fabric (silk) were the most effective. Especially, Fe mordanting treatment was higher than Al, Cu, Cr and none-mordanting. In colorfastness on the mordants, perspiration and laundering fastness showed high grade (4-5) but grades of perspiration(2-3/4) and light fastness(1-3) were low.

In this article, arrowroot is extracted in distilled water, and its dyeing properties on wool, nylon, and silk were investigated. Also the effect of mordanting (Al, Cu, Sn, Fe and Cr compounds) on the wash fastness are measured. The wavelength of maximum absorption of the arrowroot extract appears at 250 and 300nm below pH 7, but they shifted to longer wavelength at higher pH values. It appears that the optimum condition of the dyeing of wool, nylon, and silk fabric with arrowroot extract is $60^\circ{C}$, 60 min, and pH 4.0. Mordant treatments are effective in improving wash fastness of polyamide fabrics.

The tannin acid and the enzymes have been used in order to improve the ruggedness in laundry and the absorption of dyes and pigments in the textile industry for several years. The enzyme processing on the protein fiber minimizes the damage of the entire fiber and improves the dyeability by effectively modifying only the hydrophobic surface. This study tried out the structural observation by applying the Castanea crenata sieb. et. zucc. containing abundant tannin to the hair dyeing as the natural dyeing pigment along with Protease of Rhizopus sp. The dyeability was improved as compared to the dyeing using only the synthetic tanning and iron mordant. When the depth of pigment was higher in accordance with the surface observation, the enzyme dissolution had impact on dyeing and so the keratin layer on the hair surface. Accordingly, it was found that the appropriate depth was between 0.01 and 0.03%. It was estimated that 0.1% protease would treated within 30min. Consequently, it would cause the good reaction with the functional group of tannin pigment.

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%.

The pine needles has been used as medicines and it is using as dyeing as well as food. It is distributed through 50% in Korean forest. The pine needles is related to antimicrobial activity, however, dyeing properties of the extract components and effects of them are not well known yet. To examine dyeing properties of the pine needles extract, various fabrics(nylon, silk, wool, and soybean) were dyed under different dyeing conditions, and mordanted with one of five mordants(Al, Sn, Fe, Cr, and Cu). Dye uptake, Colors and Colorfastness of the dyed fabrics were measured. By the K/S values, dye uptake of all the dyed fabrics enhanced as increasing dyeing temperature and dyeing time. The highest K/S values were obtained from the protein fiber(wool and silk) fabrics dyed with water extract at $100^{\circ}C$, and with ethanol extract at $90^{\circ}C$ for 80 minutes. Colors of the dyed fabrics showed variety of yellow, brown and green colors. Colors changed by using Cu, Fe and Cr mordants: Cr-mordanted fabrics into light green, Fe-mordanted fabrics into reddish brown, and Cu-mordanted fabrics into deep green in ethanol extraction. Dry-cleaning fastness of the dyed fabrics presented good to excellent except wool fabrics dyed with ethanol extract. Washing fastness of the dyed nylon and soybean fabrics were good to excellent but wool and silk fabrics showed average grades. Most dyed fabrics were poor to light fastness.

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.
