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 aim of this study is to create smart wear that brings out the perspective person's individuality and creativity wearing these garments through various interactions. It is intended to build a prototype for a "Shape-folding Dress", which is length-adjustable skirt that responses with the environment of the wearer. In this process, four basic physical properties can be identified with fabric samples selected which are relatively stiff, including fusible interlining, organdy, silk, and ramie. In addition, two types of folding pattern specimens, "Basic Pattern" and "Diamond Pattern", and heat-steam were used to make the specimens so that the correlation could be calculated by recovery rate among flexing, stiffness and tensile properties. As a result, compared to other fabrics, the silk showed low stress to repeat folding and unfolding process, and its recovery rate of elongation deformation was stable without being affected by the different folding types and twice repeated process. In this study, forming a circuit using an Arduino, illuminance sensor, motors, and pulley, the prototype was created with a silk fabric.

For the purpose of application to new natural dyestuff, the dyeability of Rubus coreanus Miquel extract was analyzed. It was dyed in silk fabric according to various dye concentration, dyeing temperature, dyeing time, and dyeing repetition. And the effects of mordanting conditions were examined as color differences and color fastnesses. The maximum absorbance of Rubus coreanus Miquel extract was at 521 nm. The dyeaffinities were increased gradually as were increased dye concentration, dyeing temperature, dyeing time, and dyeing repetition. The dyeaffinity was increased at pre-mordanted condition, and color difference was increased distinctly at post mordanted condition. The hues of mordanted silk fabrics were RP, P, PB, BG where as non mordanted silk fabric was R. Lightfastness was the best at pre-Sn mordanted and the worst at Post-Al mordanted. Washing and perspiration fastnesses were improved on pre and post-Sn mordanted.

The natural dyestuff(chestnut dye) was manufactured from chestnut hulls by boiling in 0.5 NaOH solution and powdering in freeze dryer. To investigate the dyeability and color fastness, cotton, wool, silk and nylon fabrics were dyed under several conditions using the manufactured chestnut dye. Dyeing operation was carried in acidic dyebath of pH 4-5 because the chestnut dye is anionic. Dyeabilities on wool, silk and nylon fabrics were good, especially nylon fabrics were dyed deeper than others. But dyeability on cotton fabrics was not good. All the dyed fabrics showed excellent color fastness to crocking. Color fastness to laupdering of them were moderate to good. Also light fastness of them were moderate to good 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 gallic acid.

The dyeability and colorfastness of browning extracts from mushroom were investigated. The results of this study are as follows, 1. Browning extracts from mushroom exhibited dyeability to wool, nylon and silk. The wool and silk had the greatest K/S value at pH 4 and nylon at pH 5 2. Furthermore, the increase in K/S value corresponded to temperature, time, and the number of dyeing. 3. In most cases, the value of K/S was increased by mordant treatment. The treatment of pre-mordant caused the increase in K/S value depending on the concentration of mordant, but not in the color. Co.mordant and post-mordant treaments, however, showed various colors of YR, Y, and GY types of Munsell color wheel. 4. In the most cases, color fastness of light, drycleaning, laundry, sweat, rubbing was excellent.

Polymer cationic agent was prepared by the initial polymerization of epichlorohydrin followed by amination with diethyl-amine. Cotton fibre treated with the polymer (6∼8% o.w.f.) is highly cationic and exhibit increased substantivity for anionic dyes. The modified substrate could be dyed with direct dyes without salt or a little salt from dye bath. The increased concentration of cationic agents resulted in an increase the colour yield. Futhermore, treated cotton has an electropositive surface charge. Adsorption of direct dye can be attributed to both van der waals force and electrostatic attraction.

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.

At the interface of reducing agricultural income and increasing unemployment in agrarian economy of rural India, this article summarizes and evaluates the state of mulberry sericulture in northwest India, which includes Himachal Pradesh, Punjab, Rajasthan, Uttarakhand, and Uttar Pradesh. In $11^{th}$ plan period (2007-2012), there was an addition of 6 196 ha (217.09 %) of mulberry acreage at annual linier growth rate of 33.44%. However, total silk production could increase only by 54.64 MT (78.57%) at annual linier growth rate of 15.59 %, due to 43.93% (10.82 kg/ha) reduction in silk productivity at negative growth rate of -13.46%, annually. And now, average raw silk productivity in north-western states of India remains at 13.81 kg/ha, which is lower by 452.93 % (76.36 kg) in comparison to the national average of 100.90 kg/ha. Paper summaries the reasons for increasing cocoon yield gap at farmer's level and discuss the ways and means to increase raw silk productivity to improve the livelihood delivery of mulberry sericulture in northwest India.
