  • The purpose of this study was to estimate natural dyeing properties of Korean traditional paper (Hanji). Korean traditional paper, which made from bleached bast fiber pulp of Broussonetia kazinoki was used as base paper. As dyestuffs, hot water extractives of Phellodendron amurense bark, Rosa multiflora leaf and stalk, and Rubia cordifolia root and methanol extractives of Lithospermum erytrorhizon root were used. $Al_2(SO_4)_3$ and $Fe(OH)(CH_3COO)_2$ 0.5% solution were used as mordant. Soybean juice (10%), chitosan (0.1%), and skim milk (2%) solutions were used as auxiliary dyeing agents. Accelerated aging treatments of natural dyed Korean traditional papers were undergone at following conditions: exposure temperature, $80^{\circ}C$ relative humidity, 60%; wavelength, 340 nm; UV irradiance, $0.67W/m^2/nm$ exposure time, 24, 48, and 72 hours. Colors, color difference, and color fastness were examined for estimation of natural dyeing characteristics. The auxiliary dyeing agents treated Korean traditional papers were more superior the dyeing effectiveness about dyestuffs than untreated Korean traditional papers. The dyeing effectiveness of soybean juice treated Korean traditional paper was superior to the others. The color fastness of Korean traditional paper, which was dyed with Rubia cordifolia root extractives, was most inferior to the others.

  • Dyeing properties of silk fabric with green tea colorants were studied by investigating the effect of dyeing conditions such as concentration pH dyeing temperature and time on dye uptakes and effect of mordants on color change and dye uptakes, And various colorfastnesses of dyed fabrics were evaluated for practical use. Green tea colorants showed relatively good affinity to silk fabric and produced yellowish red color. Langmuir adsoption isotherm was obtained. Therefore it is considered that ionic bondings between colorants and silk fibers are formed. Mordants did not improve dye uptakes and affect color of dyed fabrics significantly. But mordanting adversely affected lightfastness of dyed fabrics. Regardless of mordanting colorfastness to perspiration especially in alkaline condition of dyed fabrics showed low rating compared with other colorfastness. It is concluded that mordanting is not necessary for silk dyeing with green tea colorants.

  • 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.

  • This study was carried out in order to provide useful data for planning fabrics of summer eco-friendly fashion products. The fabrics used in this study were four cellulose fibers: cotton, cotton/mulberry blended, flax, and flax/lyocell blended. Dyeing with natural indigo was carried out under three different reducing conditions (i.e., general, eclectic, and eco-friendly) that have different reducing agent and pH levels, and hydrosulfite and glucose were used as a reducing agent. The dye uptake (K/S value) of fabrics dyed with natural indigo by a reducing condition was the highest at 660nm. Regardless of the fabrics, dye uptake was the highest under the general reducing condition and the lowest under the eco-friendly reducing condition. Under different reducing conditions, the dye uptake of natural indigo fabrics with the maximum absorption wavelength indicated a difference. The colorfastness of cellulose fabrics that were dyed with natural indigo had a rate of 4 to 5 except for rubbing fastness, which indicated good colorfastness. Additionally, natural indigo-dyed cotton and flax fabrics had good antibiosis. When the color characteristics of fabrics dyed with natural indigo were measured, all of the three reducing conditions created purple blue (PB) colors, and the color characteristics of dyed fabrics by reducing condition and fabric showed significant differences.

  • This study shows the colorfastness, antibacterial activity, and deodorizing effect about cotton and silk fabrics dyed with Lithospermi Radix Extract. In the case of colorfastness, the light colorfastness showed the lowest grade, the other colorfastness was relatively good. However there are some differences according to fabrics and mordants. In the case of antibacterial activity to Staphylococcus aureus, the cotton fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted SnC1$_2$ㆍ2$H_2O$, and the silk fabrics had the most antibacterial effect at the dyed fabrics that had been mordanted A1($CH_3$COO)$_3$. In the case of deodorizing effect, the cotton fabrics showed the most deodorizing effect at the dyed fabrics that had been mordanted SnC1$_2$ㆍ2$H_2O$, and the silk fabrics showed the comparatively high antibacterial effect at the dyed fabrics that had been mordanted both SnCl$_2$ㆍ2$H_2O$ and Al($CH_3$COO)$_3$.

  • The purpose of this study was to establish a simple vitrification protocols to preserve animal cell lines derived from tissues of livestock that could be recultured. Bovine oviduct epithelial cells (BOEC) were used for the vitrification process using a 0.25 ml straw to increase cryopreservation efficiency. BOEC was cultured from the oviduct of 3.5-day estrus state, and the commercially available polyampholyte StemCell KeepTM was used as a cryoprotective agent. Using different concentrations, the viability rates of BOEC in 5, 10, 25, 50, 75, and 100% in freezing media were investigated. Survivability was determined using a differential staining technique using a trypan blue test and a CYTO-13/PI staining protocol. The viability rates of BOEC in the trypan blue test were 5.6±11.8, 12.5±7.2, 53.0±2.7, 85.1±6.9, 79.8±0.6, and 60.7±6.7% with a respective concentration of StemCell KeepTM. The viability rates in CYTO-13/PI staining were 4.6±2.5, 30.8±12.1, 58.4±2.5, 85.5±1.2, 79.8±0.6, and 71.2±1.2%, respectively. These results indicate that BOEC could be preserved with StemCell KeepTM without toxicity in a 0.25-ml straw. The optimal concentration of vitrification solution with StemCell KeepTM was determined to be 50% and can be considered as a proper preservation method for cryobanking.

  • The purpose of this study was to investigate the degradation of silk fabrics dyed with gardenia and sappanwood by Ultraviolet Light(UV). To asses the effect of uv on dyed silk fabrics, physical and chemical properties of samples were explored. K/S value rapidly decreased with increasing exposure time. Mordanting improved ultraviolet-cut ability and the sappanwood dyed samples were superior to those of gardenia dyed in ultraviolet-cut ability. Color progressively faded away as uv exposure time increased, accordingly, $L^*,\;a^*,\;b^*$, H/VC, ${\Delta}E$ were changed. Morphological change observed with SEM represented degradation of silk fabrics from the outer fibril to the inner fibril. Tensile Strength abruptly decreased as uv exposure time increased and the mordanted samples showed higher tensile strength than the unmordanted. FT-IR analysis confirmed that main peaks at 3297 and $1704cm^{-1}$ band for silk fabric were due to N-H and C=O stretching, gardenia peaks at 1654 and $668cm^{-1}$ band representing C=O(ester), C=C(alken) and O-C=O(carboxylic acids) of crocin and sappanwood peaks at $1715cm^{-1}$ band representing C=O(cyclic keton) of brazilin appeared on the samples exposed for 14 days, but these peaks indicating colorants after 28 days of uv exposure faded away due to prolonged exposure of uv.
