현재 칡은 잎, 줄기, 뿌리를 이용해 많은 연구가 이루어지고 있다. 칡의 줄기를 이용해 삼태기, 광주리, 바구니 등을 제작하고, 꽃으로는 갈화라하여 식욕부진, 구토, 장출혈, 술 중독 등에 처방하고 있다. 그 중 뿌리는 고열, 두통, 고혈압, 주독, 설사 등에 효과가 있어 뿌리를 달여 칡차로서 많이 음용되고 있다. 하지만 뿌리의 즙을 짜고 남은 칡뿌리 섬유의 잔사는 식물성 섬유소로서 현재 대부분 폐기되거나 일부 양축 농가에서 사료의 증량제로 활용되고 있는 실정이다. 매년 1,000톤이상의 칡뿌리 생산량 중 잔사가 600톤 이상 된다. 이 잔사를 이용해 펄프를 만들고 필름을 만들어 나아가 섬유를 만듬으로써 친환경적인 섬유로써의 가능성을 살펴보고자 한다.

Baekseolgi made with arrowroot flour (AF, 0 to 15% of rice flour) was steamed to examine the effect of heating on its antioxidant activity and physicochemical properties. Despite the presence of abundant dietary fiber and superior water-holding capacity of AF, moisture in baekseolgi was not significantly increased. This could partly be attributed to AF having 50% less moisture content than rice flour. Hence, hardness of baekseolgi was also not significantly altered. Total reducing capacity and flavonoid content of baekseolgi increased proportionally with the increase in AF addition. However, these values were lower than the predicted values calculated from the antioxidant activities of heated AF, which was more apparent in total reducing capacity. This indicated that the stability of non-phenolic reducing compounds in AF was lower than that of the phenolic compounds. Thermally processed baekseolgi made with 9% AF exhibited antioxidant activity without noticeable loss in the quality of the product.

우리나라에서 천연염료에 의한 염색은 일찍이 삼한시대부터 시작되었을 정도로 역사가 깊으며, 전 세계적으로 오랜 전부터 사용되었지만, 1856년 영국의 화학자 Perkin에 의해 합성염료가 개발된 이후 합성염료의 경제성, 염료보관의 용이성 등에 의해 점차 쇠퇴되어져 왔다. (중략)

Nonwoven fabrics have been widely used in various fields that include household, industrial, agricultural, medical goods, especially in the automobile industry. In this study, eco-friendly fiber materials were developed and investigated as a substitute material for polyester fibers in nonwovens. To make plant fiber bundles, stems of Indian mallow (IM), and Kuzu vine (KV) were retted; in addition, the non-cellulose component was partially removed. Plant fiber bundles and polyester fibers (P) were blended and needle punched to produce nonwovens. Five kinds of nonwovens were manufactured: P100 (Polyester 100%), IM10 (IM 10% and Polyester 90%), IM20 (IM 20% and Polyester 80%), KV10 (KV 10% and Polyester 90%), and KV20 (KV 20% and Polyester 80%). The color values, surface appearance, tensile strength, elongation, tear strength, abrasion strength, flexstiffness, moisture regain, water or oil absorbency, and static electricity of manufactured nonwovens are investigated. As the blended ratios of IM or KV increased, the brightness of nonwovens decreased compared to that of polyester 100%. Tensile strength, tear strength, abrasion strength, and flexstiffness of IM10 as well as KV10 were higher than those of P100, IM20, and KV20, resulting from the influence of the structure and properties of nonwoven fibers. Moisture regain and water or oil absorbency increased, while static electricity decreased in proportion to the amount of plant fibers. IM or KV and polyester blended nonwovens showed improved properties over P100 that could be substituted for P100 as a novel material for textiles.

The applicability of arrowroots as materials for paper manufacture was investigated by evaluating the characteristics of arrowroots pulping and pulps, and the surface characteristics of paper made of arrowroots. The results is as follows. The yield of grounded pulp, alkaline pulp, grounded bleach pulp, and alkaline bleach pulp are 98.0%, 37.7%, 84.8%, and 32.5%, respectively. The extraction components in arrowroot's fibers was shown high in 1%-NaOH extraction. The amount of holocellulose and lignin were largely decreased, but a slight decrease was shown in the bleaching processes. Many shivers were shown in the grounded fibers. The amount of shivers was decreased and the single fibers were increased during the process of bleaching. The alkaline pulp and the alkaline bleach pulp showed high in the beating time and freeness than the grounded pulp and grounded bleach pulp. The conditions of sheet surface according to beating time is effected largely by the conditions of original pulp.

The purpose of this research is to investigate the anatomical and chemical properties of arrowroots for the use of paper fibers. The cells consisting of arrowroots showed certain affinities with those in the fibers and vessels of hardwood. Its parenchyma cells showed different shapes with those of hardwood. It was observed that starch was filled in the multi-shape cells. The average width and length of arrowroot fibers were $15.2{\mu}m$ ($11.1-20.3{\mu}m$) and 1.9 mm (1.49 mm-2.31 mm), respectively. In the chemical characteristics of arrowroots, the contents of cold- and hot-water, alcohol-benzene, and alkali extractives were 12-17%, 15.6%, and 38.8%, respectively. Its chemical composition was 61.3% holocellulose, 15.5% lignin and 2.0% ash.

In this article, arrowroot is extracted in distilled water, and its dyeing properties on wool, nylon, and silk were investigated. Also the effect of mordanting (Al, Cu, Sn, Fe and Cr compounds) on the wash fastness are measured. The wavelength of maximum absorption of the arrowroot extract appears at 250 and 300nm below pH 7, but they shifted to longer wavelength at higher pH values. It appears that the optimum condition of the dyeing of wool, nylon, and silk fabric with arrowroot extract is $60^\circ{C}$, 60 min, and pH 4.0. Mordant treatments are effective in improving wash fastness of polyamide fabrics.

This study was conducted to investigate the effects of embryo development by fusion condition on the nuclear transfer with brindle coated cow's ear cells. Ear cells were transferred into an enucleated oocyte and fused with cytoplasm in the fusion condition with 1.9kv/cm, 2.0kv/cm, 2.1kv/cm each 10 and 20ug duration Nuclear transfer embryo were activeted with a combination of 5ug/ml and 1.9mM 6-DMAP (4min, 4h). Fusion rate was 51∼68% range among fusion condition (1.9, 2.0, 2.1kv/cm; 10, 20us). But, cytoplasm lysis rate was increased by higher electric condition (0∼51.8% range). Each parameter's cleavage and blastocyst formation rate were 1.9kv/cm for 10us (75.8 and 19.5%), 20us (69.8 and 48.6%), 2.0kv/cm for 10us (76.9 and 20.0%), 20 us (68.5 and 40.9%), 2.1kv/cm for 10us (70.5 and 44.2%), 20 us (68.5 and 27.0%). We compared the effectiveness of cloning for between brindle coated cow's ear cells and Hanwoo fetal fibroblast cells. There was no significant differences in the fusion rate and developmental rate to the blastocyst stage. After transfer of blastocysts derived from nuclear transfer embryos, pregnancy rates of the Hanwoo fetal fibroblast cells and brindle coated cow's ear cells were checked pregnant on day 60 as assessed by ultrasonography, 40% (2/5) and 15.8% (3/19), respectively. This studies conclude that brindle coated cow's ear cells have the developmental potentiality to term by nuclear transfer. These results demonstrate that the increased the field strength was to be profitable for development of blastocyst or reduce of cytoplasm's damage than increasing the pulse duration.
