  • 최근 산업 발달에 의한 환경문제와 석유자원 감소에 따라 섬유시장에는 Eco-friendly 바람이 강하게 불고 있으며 리싸이클 제품이 급부상하고 있다. 폴리에스터계 고분자 제품, 그 중에서도 PET 병의 재자원화를 살펴보면 기계적, 열적으로 처리하여 물질을 바꾸지 않고서 회수하는 방법인 Mechanical Recycling과 원료를 분해하여 회수하는 방법인 Chemical Recycling이 있다. 이러한 리싸이클을 통하여 에너지 절감, 저탄소, 유해물질 감소, 환경정화 및 폐기물 감소로 환경부하가 완화되며, 자원의 효율적 재사용이 가능하다. 리싸이클 PET 섬유제품은 의류 인테리어용과 같은 한정된 용도뿐만 아니라 자동차용 부품소재 및 내장 부품 등 산업용으로도 사용가능하다. 본 연구에서는 리싸이클 PET로 제직한 직물에 정련과 호발가공을 하여 이러한 전처리에 따른 물리적 열적 특성의 변화를 비교 분석하였다. 그 결과 정련과 호발가공을 한 리싸이클 PET 직물의 인장 인열 강도가 미처리 직물과 비교하여 감소하는 결과를 보였으며 마모 파열강도는 큰 차이를 보이지 않았다. 반면에 TGA와 DSC를 이용한 열분석 결과 열적 특성 및 결정화도는 일부 차이를 나타내었다.

  • The Belgian textile wallcovering has the following background. The unique oceanic climate is optimized for flax. Beginning in the thirteenth century, British wool was produced for export to Britain or neighboring countries. Since the 15th century, Flemish paintings were influenced by color implementations, and these colors have influenced the developments of tapestry and art. Since that time, tapestry and paintings combined with paper technologies and Oriental civilizations, such as silk, that had been developed through trade ports, have been transformed into the form of current wallcoverings. Belgium produces the highest quality textile wallcovering using natural materials i.e., a combination of irregular and modern materials, and the implementation of different colors. The Belgian textile wallcovering is also a good representation of nature at the Heimtextil 2018, It provides a wide range of colors while retaining the best styles for wallcoverings in Belgium. The characteristics of Belgian wall coverings are: First, the high proportion of achromatic colors, especially the white ones, are analyzed for current trends. Second, it expresses the characteristics of materials by using only one material. This not only shows a high level of understanding of natural materials, but also shows a high level of development in terms of processing technology. Thirdly, linen was made into a formative expression using wrinkle processing and by printing geometric patterns, the rough texture of natural materials was expressed in harmony with modern patterns.

  • This study fabricated low thermal conductive polyacrylonitrile (PAN)-based carbon fibers containing cellulose particles while maintaining their mechanical properties. The high thermal conductivity of carbon fibers limits their application as a high temperature insulator in various systems such as an insulator for propulsion parts in aerospace or missile systems. By controlling process parameters such as the heat treatment temperature of the cellulose particles and the amount of cellulose added, the thermal and mechanical properties of the PAN-based carbon fibers were investigated. The results show that it is possible to manufacture composite carbon fibers with low thermal conductivity. That is, thermal conductivities were reduced by the cellulose particles in the PAN based carbon fibers while at the same time, the tensile strength loss was minimized, and the tensile modulus increased.

  • Organic materials are suitable for use in photoelectric conversion devices. Thus, Organic semiconductors are promising materials for photovoltaic devices and other optoelectronic applications such as light emitting diodes(LED). The organic solar cell seems to be the usefulness in comparison with the inorganic solar cell in terms of workability, ease of processing, low cost, flexibility and area expansion. (omitted)
