대마에 대한 분석 결과, 인피 섬유의 경우 리그닌 함량은 7.6%로 다른 목질계 바이오매스나 일년생 초본류와 비교하여 매우 낮은 리그닌 함량을 나타냈으며 탄수화물 함량은 65.4%로 목질계 바이오매스와 유사하고, 초본류보다는 오히려 높았다. 목부는 리그닌 및 탄수화물 함량이 활엽수와 유사한 경향을 나타내었는데 특히 높은 자일란의 함량이 확인되었다. 또한 회분 함량이 인피섬유와 목부에서 각각 5.0%와 2.3%로 낮은 값을 나타내어 당화 및 발효 공정에 적용될 때 회분에 의한 공정 장애(스케일링 등)의 가능성을 낮추어 줄 것으로 사료되었다. 최종적으로 이러한 화학적 분석을 통해 대체에너지 생산을 위한 자원으로서 대마의 가능성을 확인할 수 있었다.

The fashion industry saw the emergence of environment-friendly and natural fabric materials recently. The naturalism trend has established sectors in the textile and fashion industry also. Ramie and hemp have long been favored fabric materials in Korea especially for summer. The hand-related mechanical/physical properties of the fabric specimens were analyzed using a fabric objective measurement system, KES(Kawabata Evaluation System). Subjective evaluation was also implemented based on a series of selected adjectives. Studies on natural dyeing methods are important since the establishment of scientific approach is needed in terms of environment and human safety along with the reproduction of traditional natural dyeing methods. In this study, linen, ramie, hemp, and cotton/polyester/linen union fabric specimens were used for the natural dyeing using Rubia akane Nakai with the mordant of gallnut. ${\Delta}E$ values of dyed fabric specimens, mordanted and dyed once using Rubia akane Nakai, increased significantly compared to those of repeatedly dyed fabric specimens without mordanting.

We made densified wood pellet by hemp woody core as replacing wood resource. Hemp was separated into the bast fiber and the woody core by hot steaming treatment. The hemp woody core had a similar lignin content and carbohydrate composition with hardwood. Also, the hemp had a low ash content, which resulted in a low ash formation in pellet burning. Heating value of the hemp pellet had a very similar to the pellet made by hardwoods. The hemp woody core can replace hardwood for densified wood pelletmaking.

The utilization of non-woody fibers with the fast growing annual plants has occurred in the paper industry to replace wood and preserve environment of the earth. The non-woody fibers generally used for papermaking are paper mulberry, gampi, manila hemp, rice straw, bamboo, and coton linter etc.. Recently Kenaf has been spot-lighted for the same application. Kenaf is an annual plant of Hibiscus species of Malvaceae family. Kenaf, a rapid growing and high harvesting non-woody fiber plant, was identified as one of the promising fiber sources for the production of paper pulp. This study was carried out to investigate the pulping characteristics of Kenaf bast fiber for Hanji (traditional Korean paper) manufacturing by different pulping methods, such as alkali, alkali-peroxide and sulfomethylated pulpings. It was possible to make superior grade of Hanji. Especially sulfomethylated pulping was resulted in superior pulp in terms of higher yields and qualities in comparison to those of the other pulping methods. Hanji from sulfomethylated pulp was shown the highest brightness of over 60% and higher sheet strength. In addition, the morphological features of pulp fibers (pulp compositions) affect to the sheet properties. Therefore the effect of fiber distribution index(FDI) which was calculated from the data of Confocal laser scanning microscopy(CLSM) on the sheet properties of Kenaf Hanji was also discussed.

종자 수확 후 버려지는 산업용 대마를 이용한 목질 펠릿제조 가능성과 제조된 펠릿의 특성을 살펴보았다. 산업용 대마의 성분 분석 결과 활엽수와 비슷한 리그닌 함량과 당구성을 보였으며, 회분 분석 결과 무기물 함량이 0.5% 정도이어서 연료로 사용할 경우 재의 생산량은 크지 않을 것이다. 원소 분석 결과 대기 오염을 유발할 수 있는 질소와 황 함량을 분석한 결과, 황 성분은 전혀 포함하지 않고 있으며, 약간의 질소 성분을 포함하고 있는데 이는 현사시나무와 비슷한 수준이었다. 고위발열량 측정 결과 대마 목부는 현사시나무보다 다소 낮은 값을 나타내었다. 바이오매스 생산량이 큰 대마 목부를 이용하여 제조한 펠릿은 활엽수로 제조한 펠릿과 비슷한 화학적 성질과 발열 특성을 가질 것으로 기대되어 고체연료로서의 이용이 가능할 것으로 사료되었다.

Buddhist articles from various periods in the Vairochana Buddha statues, which are currently housed in the Haeinsa Temple's Supreme Buddha Hall and Beopbojeon Hall. This research concentrates on the artifacts found inside the storage boxes, which was placed inside the Buddha statues in 1490. A total of 24 pieces of fabric articles found inside the Virochana Buddha in Beopbojeon and 213 pieces from the Supreme Buddha Hall were examined. The types of textiles are as follows: bast fiber, silk, cotton, and union cloth. Bast fiber consisted of ramie and hemp. For silk, tabby woven with plain weave, spun silk, and thin tabby were found. And twill damask made with twill, Sa and Ra with the leno weave, and satin damask made with the satin weave were also found. Also the two Jeogoris and three Jogakbos were found, the one Jeogori was made with Hwan. The Buddhist articles in the Vairochana Buddha of Haeinsa have been preserved well and its colors have remained virtually the same from the time of its original placement. Therefore these articles are very important in understanding the textile characteristics, weaving techniques, dying techniques as well as traditional colors.

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.

This study was carried out to investigate the characteristics of the lining papers which had been separated from six pieces of paintings and calligraphic works of the 18th and the 20th century. A total 20 kinds of lining papers were examined on the physical properties, colors, fiber morphology, and color reactions. The grammage and thickness of lining papers which had been used hanging-scroll type works were higher than those of folder types. On the other hand, the grammage and thickness of the first layer lining papers which had been separated from silk ground works were lower than those of paper ground works. All kinds of lining papers were colored from yellow to yellowish red because of unbleaching and deterioration. Through the examination on fiber morphology and color reactions, lining papers were verified that all of those were made from paper mulberry bast fiber but the first layer of the Mukjukdo. The lining paper which of the first layer of the Mukjukdo was verified that it was made from mixture of paper mulberry, hemp, and spruce pulps.
