The dying properties of fabrics with Chaenomelis Fructus extract were studied through an investigation of the characteristic of Chaenomelis Fructus colorants, the effect of dyeing conditions (dye temperature, dyeing concentration, and times on dye uptakes), effect of mordant, effect of UV irradiation, and color change in addition, antimicrobial ability and deodorant ability were estimated. In the UV-Visible spectrum, the wavelength of maximum absorption of Chaenomelis Fructus extract was 280 nm and showed that tannin is the major pigment component. From the increase of absorbance by UV irradiation, it was assumed that catechol tannin color was developed through UV irradiation. An increased dyeing concentration resulted in a larger dye uptake. Dye uptake increased as the dyeing time and temperature increased. Chaenomelis Fructus extract showed relatively good affinity to silk than cotton. Mordant, Fe and Cu were effective to increase the dye uptake of cotton fabric in addition, the dye uptake of silk fabric mordanted with Fe and K improved. UV irradiation let the color of dyed fabrics develop regardless of the UV irradiation stage however, UV irradiation on the dyed fabric was more effective than on the extract for the color development. Dyed silk fabric showed very good antimicrobial abilities of 99.9% in addition, deodorant ability improved in the fabric dyed with Chaenomelis Fructus extract.

The dyeing properties of protein fiber with pine needles colorants were studied through an investigation of the effect of dyeing conditions such as dye concentration, dyeing temperatures and time on dye uptakes, effect of mordants, and color change. In addition, the various colorfastness of dyed silk and wool fabrics were evaluated for practical use. The antimicrobial ability, ultraviolet-cut ability, and deodorant ability were also estimated. The dye uptake increased as the dyeing concentration increased and this enabled the obtainment of the Langmuir absorption isotherm. The dye uptake increased as the dyeing time and temperature increased. Pine needles colorants showed relatively good affinity to protein fiber and produced a yellow color. Post-mordanting was more effective than the pre-mordanting, and the dye uptake of fabrics improved by mordanting. Except for washing, the colorfastness of dyed fabrics showed a low rating. However, the colorfastness to light and the dry cleaning of fabrics mordanted with N.Cu, and the friction fastness of fabrics mordanted with Cu improved. The guide fabrics showed very good antimicrobial abilities of 99.9%; in addition, the ultraviolet-cut ability and deodorant ability improved in fabrics dyed with pine needles extracts.

The aim of this study was to investigate the antimicrobial, antiperspirant and deodorant effect of herb mixtures including Schisandra chinensis(SC). This herb mixtures including Schisandra chinensis was made of Astragalus membranaceus(AM), Triticum aestivum(TA), Atractylodes japonica(AJ) and peppermint essential oil extracted from Mentha piperita(MP). We examined antimicrobial activity, antiperspirant activity and L-leucine dehydrogenase activity of the herbal extracts. We found that the mixture of SC and MP have the best antimicrobial effects on B. subtilis subsp. spizizenii and mixture of SC, AJ, AM and TA have best antiperspirant effect. Moreover, the combination of SC and AM showed the most inhibitory effect on L-leucine dehydrogenase activity. These results suggested that the herb mixtures Including Schisandra chinensis have good antimicrobial and antiperspirant effects.

Dyeing properties of cotton and ramie fabrics with pine needles colorants were studied by investigating the analysis of pine needles colorants, the effect of dyeing conditions (such as dye concentration, dyeing temperatures and times on dye uptakes), effect of mordants, and color change. The various colorfastness of dyed fabrics were evaluated for practical use; in addition, the antimicrobial ability, ultraviolet-cut ability, and deodorant ability were estimated. In the UV-Visible spectrum, the wavelength of the maximum absorption for pine needles extract was 285nm, and pine needles colorants produced a yellow color. From FT-IR and GC-MS results, it was assumed that chromophoric substance from pine needles extracts were mixed with flavonol tannin and flavanol tannin. An increased dyeing concentration resulted in a larger dye uptake and a Freundlich absorption isotherm was obtained. A larger dye uptake occurred as the dyeing time and temperature increased. Post-mordanting was more effective than pre-mordanting and the dye uptake of fabrics improved by mordanting. The colorfastness of dyed fabrics showed a low rating; however, colorfastness to washing and dry cleaning of cotton fabrics mordanted with N.Cu, and friction fastness of ramie fabric mordanted with Cu improved. The dyed fabrics showed very good antimicrobial abilities of 99.9%. In addition, the ultraviolet-cut ability and deodorant ability improved in fabrics dyed with pine needles extracts.

The dyeing properties of cotton fabrics with bamboo colorants were studied by investigating the analysis of bamboo colorants, the effect of dyeing conditions (dye concentrations, dyeing temperatures and times on dye uptakes), effect of mordants, and color change. The various colorfastness of dyed fabrics were evaluated for practical use; in addition, the antimicrobial ability, ultraviolet-cut ability, and deodorant ability were also estimated. In the UV-Visible spectrum, the wavelength of the maximum absorption for bamboo stems and leaves extracts was found to be 280nm and 295nm, respectively; in addition, bamboo colorants produced a yellow color. From the FT-IR and GC-MS results, it was assumed that the chromophoric substance from bamboo extracts was composed of flavones substances with tricin. An increased dyeing concentration resulted in a larger dye uptake and a Freundlich absorption isotherm was obtained. A larger dye uptake occurred as the dyeing time and temperature increased. The post-mordanting was more effective than pre-mordanting. Mordants, Fe and N.Fe, were effective for an increased dye uptake. The color of fabrics mordanted with Cu and N.Cu changed to GY. Regardless of mordanting, the colorfastness on the washing of dyed fabrics showed a low rating compared to other fastness. Mordanting adversely affected the lightfastness of dyed fabric. The dyed fabric showed very good antimicrobial abilities of 99.9%. In addition, the ultraviolet-cut ability and deodorant ability improved in cotton fabric dyed with bamboo extracts.

The dyeing powder drawn out from Dryopteris crassirhizoma by water was concentrated. Using this powder, the silk and the cotton fabrics were dyed and they measured with the K/S value, surface color, mordant quantity in order to evaluate the dyeability, antimicrobial and deodorant properties. The colorant of Dryopteris crassirhizoma was proved flavonoids by FT-IR spectrum. The K/S values of silk were much higher than those of cotton, the color yield of the silk and cotton fabric were most efficient the postmordanting method. The surface colors on the dyed fabric depended heavily upon mordants used or mordanting methods. For all cases, the value of the dyed fabric was generally dark. The chroma produced clear for the Al-mordant of silk and the Cu-mordant of cotton in the 3% concentration of mordants, the color difference was distinct when using the Fe-mordant. The K/S values of cationized cotton were much higher than cotton. The color fastness was significantly improved when mordants were added, In the case of the light fastness, Fe and Cu-mordants improved more than 1 level. The Cu-mordant showed the greatest antimicrobial and deordarant activity on both of the silk and the cotton.
