Bamboo leaves, as natural dye provide unartificial fresh green, are known for expert property at anti-bacterial, anti-aging, anti-oxidation, skin whitening, moisturizing, peeling of horny, deodorizing and some skin disease like as eczema and inflammation without any allergic response. Also, It is quite common to obtain bamboo leaves from our surrounding but most of them were not in use. On purpose of development the way of recycle with common material to dye, bamboo leaves were used to dye on ramie fiber which is valuable for both of apparel and industrial field and investigated their dyeing property. Using extract from bamboo leaves, dyeing property was examined with dyeability, colorimetric property, light fastness and wash fastness under different conditions by extract density, dyeing time, dyeing method and mordants. As results, dyeing was generally colored in yellowish, K/S Value was shown more higher on hemp fiber than ramie. The most optimum dyeing condition was investigated on pre-mordant treatment, dyeing temperature $60^{\circ}C$, dyeing time 30min and extract density 400%. On the treatment with mordant(Al, Fe, Cu), dyebility on both of hemp and ramie fiber were increased by mordant. Especially with Copper(Cu) as mordant, dyebility was highly increased than any other mordants and dyeings showed in deep color. Also on the fastness test which is the most important to natural dyeing, wash-fastness showed good performance with 4-5 grade but light-fastness was above 4 grade on both of hemp and ramie fiber, lower than wash-fastness overall.

This study is about the fabric attached to the relics excavated from the Shimchun-ri tomb of the 4th century and the Moonsan-ri tombs of the 5th century. We studied 5 pieces of fabric from the Shimchun-ri tomb: one piece was silk and the other four pieces were hemp. We were able to observe 8 pieces from the four tombs in Moonsan-ri, All of them except one ramie were silk. The two kinds of bast fiber found in the tombs of Shimchun-ri and Moonsan-ri were hemp and ramie, and they were found to be plain woven with S-twist thread which thickness is uneven. The density was more fine compared to the hemps found in the Kaya or Shinra tombs of the similar era. All of the silk textiles found in the Shimchun-ri and Moonsan-ri tombs used non-twisted thread, and were plain woven. Also, we found degummed and raw silk from the tombs. The average density of the silk textiles from these tombs are similar to other areas of the same time, and studies show that they used non-twisted thread in plain woven silk found in other tombs. Therefore, we can conclude that they usually used non-twisted thread when producing silk textiles.

The conditions for minimizing dyes and additives when dyeing cellulose fibers such as linen, ramie, and hemp fabrics were obtained using glucose, an organic reducing agent. Dyeability and colorfastness were measured through repeated dyeing. The overall surface dyeing concentration followed the linen>hemp>ramie order, and most of the colors were in the range of PB (PurpleBlue). As the glucose concentration increased, the blue series was strengthened, and the color was dark and clear. It was determined that glucose the concentration of 4g/L was appropriate for minimizing the amount of dye. When the dyeing temperature was 30℃, the surface dyeing concentration was the highest, and the color was dark and clear. Although the dyeing concentration increased as NaOH concentration increased, 3g/L (pH 12.37) was considered appropriate for the minimum NaOH concentration, which becomes gradual after the dyeing concentration increased rapidly. It was found that the surface dyeing concentration, when repeated six times for 5 min, was better than that of dyeing once for 30 min. Washing, rubbing, and perspiration colorfastness were all found to be excellent in grades 4-4-5, and colorfastness to light was excellent in grades 5 of linen and hemp and grade 4 of ramie.

Corn stover, hemp woody core and tobacco stalk were treated by dilute ammonium hydroxide soaking for improving the enzymatic saccharification of cellulose and xylan to monosaccharides by commercial cellulase mixtures. As more lignin removal by dilute ammonium hydroxide impregnation led to more enzymatic saccaharification of cellulose and xylan to monosaccharides (corn stover vs tobacco stalk). There was no relationship between xylan removal by dilute ammonium hydroxide impregnation and enzymatic saccharification of polysaccharides in pretreated samples. Except corn stover, lower temperature and longer treatment ($50^{\circ}C$-6 day) was less lignin removal than higher temperature and shorter treatment ($90^{\circ}C$ 16 h). Corn stover showed the highest enzymatic saccharification of cellulose and xylan but tobacco stalk showed the lowest.

The purpose of this study is to determine how the people's view on afterlife affects their perception about shrouds. As part of analytical research, the survey was carried out to take a look at the basic thoughts that average persons have on afterlife. This paper also performed the survey on what the shroud reminds the subjects of. Specifically, the questionnaire survey was conducted to see what the people think the necessity and appropriate cost of shroud and see if they have any plan to get it provided in detail. Data from this work were statistically processed and empirically analyzed. Findings of this study can be summarized as follows. As to the funeral methods, the subjects in this work preferred cremation to burial. It was found that they recognized shrouds as necessary, but they did not have a thought in a serious manner that the suit for the dead would affect the repose of the dead and guide his or her soul to the heaven. Those respondents did not have any immediate plan to purchase shrouds, either. However, they considered the price of shroud as most important when they might come to choose the garment. With regard to the quality, it turned out that they preferred the domestic shrouds whose material are natural to those from foreign country. Also, they opted for such a kind whose shape is not so different from that of casuals they would usually wear and whose color is same to the main material of the original garment. The common material preferred most by the subjects was a hemp. The subjects' view of afterlife was not greatly related not only to how much they recognized shrouds as necessary but also to their preference for materials and patterns. On top of this, their unique taste for particular types of shroud was found to be significantly dependent on whether their view of afterlife is positive or negative, whether they firmly believe in afterlife, whether they take the absolute predestination and whether they accept the prayer-effect relationship in terms of psychology.

This study was aimed to isolation and identification of attached bacteria on the clothes excavated from Deajeon area dating on the 16th century. From the observation with colony shape, 17 bacterial strains were isolated, and then 7 bacterial strains were identified with morphological and biochemical characteristics. Streptococcus sp., Alcaligenes faecalis, Gemella sp., Acinetobacter sp., Pseudomonas vesicularis, Aeromonas sain. salmonicida, Moraxella spp. In observation of the bacterial strains by the sort of textile, more bacterial strains were found in silk, cotton, and cotton batt than in ramie and hemp. It is suggest that hemp has antibacterial characteristics due to the presence of lignin. In the comparison washed samples with unwashed ones, there were more kinds of bacterial strains in washed samples. In the cellulase activity tests, all isolated bacteria had low level cellulase activity.

Previous studies are used to examine cellulose content, degumming period, fiber quality, production yield, production cost, development limit of fiber according to physical, chemical, and microbial degumming methods. Three types of degumming methods are used to measure surface condition after degumming, necessity of additional degumming and degree of impurity removal. First, previous studies confirmed that the microbial degumming method is superior in terms of cellulose content, fiber quality, production yield, production cost, and fiber development possibility. Second, surface condition and the necessity of additional degumming were analyzed by SEM. The black skin binding material was removed in the case of the Sangnangyi and chemical degumming; however, it was insufficient and further degumming was required. Skin fiber binding material was removed in the case of microbial degumming and the surface was cleanest after degumming; in addition, most showed the form of yarn decomposition. The FT-IR spectrum determined the degree of removal of impurities and showed that it can utilize inherent physical properties as the best degumming method. The degree of removal of pectin and lignin by microbial degumming was cleanest with hemicellulose also reduced by microbial degumming.
