초록

무당거미와 나무껍질게거미줄의 열 안정성 및 기계적 성질 등을 측정하고, 그 성질들을 합성 섬유인 아라미드(aramide)와 폴리에스테르(polyester) 등의 측정 결과와 서로 비교하였다. 열 안정성에서 거미줄은 비록 상업용 섬유로 사용되는 아라미드나 폴리에스테르에 비해서는 낮았지만 기계적인 성질에서는 폴리에스테르보다 월등 우수한 결과 값을 보여주었다. 거미줄에 포함되어 있는 수분이 열 안정성과 기계적 성질에 미치는 영향을 조사하기 위해 두 종류의 거미줄을 $100^{\circ}C$의 진공에서 각각 다른 시간 별로 열처리를 하였는데, 1.5시간 동안 열처리를 시킨 후의 열 안정성과 기계적 성질이 최고 값을 나타내었다.

The thermal stability and mechanical properties of Nephila clavata and Bassaniana decorata spider silks were measured and compared with those of aramid and polyester fibers. The thermal stability of the spider silk was lower than those of the commercial aramid and polyester fibers. However, the mechanical properties of the spider silk were far superior to that of the polyester fiber. The effect of the water content of the spider silk on its thermal stability and mechanical property was examined by conducting the silk to heat treatment at $100^{\circ}C$ under vacuum for various times. The results indicated that spider silk subjected to heat treatment for 1.5 hr had excellent thermal stability and mechanical property.
