For the development of high quality textiles, silk fabrics were dyed repeatedly with persimmon juice by padding mangle. We evaluated the mechanical properties and hand value by Kawabata Evaluation system for dyed silk fabrics. The results obtained from this study were as follows. With the increase of repeating padding times of dyeing, the linearity load-extension curves of the silk fabrics were increased; however, the tensile resilience of fabrics decreased. The hysteresis values of shear force were increased without significant change of shear stiffness. The coefficient of friction values were also decreased and geometrical roughness values were increased. The silk fabrics dyed with persimmon juice had shown the thickness and weight grow as the number of padding increases. The hand values of silk fabrics which were classified into 6 items in the Kawabata Evaluation System, were evaluated as repeating times of dyeing with persimmon juice. The hand values of Koshi(stiffness) and Hari(anti-drape stiffness) were increased, whereas Shinayakasa (flexibility with soft feeling) and Fukurami(fullness and softness) were decreased by dyeing with persimmon juice. However there was no significant change in hand values according to repeating padding times of dyeing.

The purpose of this study is to investigate the dyeability, antibacterial activity and deodorization on cotton and silk fabrics dyed with extracted solution from gardenia. The results are as follows: 1. The K/S value of silk fabrics was higher than that of cotton fabrics, and the K/S value was slightly increased by mordanting with $SnCl_2.2H_2O$ and $K_2Cr_2O_{7}$ on cotton and silk fabrics. 2. Cotton fabrics showed yellow from GY to Y and silk fabrics showed yellow or reddish yellow from GY to Y-YR. 3. The fastness to washing of cotton fabrics was very poor and that of silk fabrics was middle or lower, excluding good fastness to wool contamination of both fabrics. The fastness to dry cleaning and rubbing of both fabrics was very good. The fastness to perspiration of cotton fabrics was middle or higher, but that of silk fabrics was much better than that of cotton fabrics. The fastness to the light of both fabrics showed very poor with 1 grade. Dyeing fastness was slightly improved by mordanting on both fabrics. 4. Silk and cotton fabrics did not show antibacterial activity, but the activity of silk fabrics was higher than that of cotton fabrics. The antibacterial activity was increased by mordanting. 5. The deodorization of dyed cotton and silk fabrics was excellent, and that of silk fabrics showed better than that of cotton fabrics.

The natural dyestuff(squid ink) was manufactured from squid ink by boiling in 0.1% NaOH solution and powdering in freeze dryer. Cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured squid ink to investigate the dyeability and color fastness. Dyeing was operated in acidic dyebath of pH 4 because the squid ink is anionic. Dyeabilities on wool, silk and nylon fabrics were good, especially silk fabrics were dyed deeper than others because of being amine group. But dyeability on cotton fabrics was low and developed with chitosan treatment. All the dyed fabrics showed excellent in color fastness to crocking and laundering. Also light fastness of them were excellent except nylon. The light fastness of dyed-nylon fabrics was as poor as grade 1, but they could be improved to grade 4 by aftertreatment with gallicacid. Useing the natural dyestuff-squid ink powder, we could execute whenever we want to dye fabrics in the adequate concentration. Dyeabilities were developed according to repeating times of dyeing and the increased dye concentration. We could recycle the wasting sources.

To get the variety of color by natural dyeing, cotton and silk fabrics were dyed with natural indigo and safflower in turn. The two ways of dyeing processes were carried. First, silk and cotton fabrics were dyed repeatedly in safflower dyebath to five times to get the five fabrics dyed in different shades. And then indigo dyeing process was carried on the top of the dyed fabrics with safflower. In second way, the fabrics were dyed in five stages of shade by repetition of dyeing process in indigo dyebath. And then safflower dyeing was carried on the top of the dyed fabrics with indigo. When indigo dyeing process was added on the top of the fabrics dyed in five shades with safflower, the color differences decreased between five shades of fabrics, their color values got similar in hue, shade and chroma. When safflower dyeing process was added on the top of the fabrics dyed in five shades with indigo, the fabrics showed different hue of colors between red and blue of Munsell color circle such as RP, P and PB. Like almost of fabrics dyed with plants materials, the lightfastness and laundering fastness of dyed samples were poet and drycleaning fastness were good.

The chemical composition of natural powder dye $Pinux^{TM}$ manufactured from Pinus radiata bark and dyeability of dyed silk fabrics with $Pinux^{TM}$ were examined. It is made up of the optimum dyeing condition of silk fabric according to the dyeing concentration, dyeing time, and dyeing temperature. Also, we examined the colorfastness and antibiosis of dyed silk fabrics to washing, rubbing, perspiration and light. For the analysis of the chemical composition of $Pinux^{TM}$, the total contents of phenolic compound, proanthocyanidin(PA) and anti-oxidative activities of the dye were analyzed. As a result, it was found that the main components of the $Pinux^{TM}$ manufactured from Pinus radiata bark is proanthocyanidin, mostly a flavonoid containing a procyanidin structure, and it consists of approximately 63% phenol. As a result of examining the dyeability of silk fabrics with $Pinux^{TM}$, it showed that the dyeability was best under the conditions of the concentration of dye $1{\sim}1.5%$(wt/v%), dyeing time of 90 minutes, and dyeing temperature at $90^{\circ}C$. It was found that the colorfastness of dyed silk fabrics, colorfastness to washing, perspiration for acidic and rubbing were as good as grade 4 or 4-5. However, the colorfastness to light was low at grade 1, the same as the results of other natural dyed fabrics. As a result of the antibiosis measurement for the $Pinux^{TM}$-dyed silk fabrics, it showed high antibacterial properties to Staphylococcus sureus at 99.6%.

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.
