In this study, we investigated several chemical and physical characteristics of 4 weed seed fibers; Hemistepta lyrata (HEMLY), Imperata cylindrica var. koenigii (IMPCK), Metaplexis japonica (METJA) and Typha latifolia (TYPLA). In chemical composition, there were 74 (TYPLA)-88.5% (METJA) of holocellu...

바이오복합재료 연구분야란? | (2013)은 식물섬유의 주성분인 셀룰로오스 시장분야를 9가지로 즉, 1) 직물, 2) 부직포, 3) 목재 및 판재, 4) 펄프, 종이 및 골판지, 5) 셀룰로오스 용해 펄프(Cellulose dissolving pulp), 6) 셀룰로오스계 필름, 7) 건축자재, 8) 셀룰로오스계 섬유 복합재료, 9) 녹색화합물(Green chemicals)로 나누어 제시하고 있다. 이들 중 최근 가장 관심을 받고 있는 것은 위에서 언급한 바와 같은 장점 때문에 바이오복합재료(bio-composite) 연구분야, 즉 식물섬유를 여러가지로 처리하여 자체만으로 또는 화학수지와 복합시켜 새로운 기능의 소재를 만들거나, 생분해성이 높은 수지 또는 경량화 소재 등을 개발하여 전자, 자동차, 화장품, 의료 및 농식품용 화학소재로 활용하려는 분야이다(Anuar and Zuraida, 2011; Faruk et al., 2012; Klemm et al. | |
식물섬유를 기원에 따라 분류하면? | , 2014). 식물섬유는 기원에 따라 활엽수 섬유, 침엽수 섬유, 인피섬유, 잎섬유, 종자섬유, 짚섬유(straw fiber) 등 여러가지가 있으며(Thakur and Thakur, 2014), 식물섬유를 비롯해 매년 지구전체에서 합성, 분해되는 천연섬유는 1010-1011 톤에 이른다고 한다(Helbert, 1996). | |
지칭개, 박주가리, 큰부들, 띠 종자섬유 중 Holocellulose 함량이 가장 높은 것은? | 본 연구는 지칭개, 박주가리, 큰부들, 띠 종자섬유에 대한 간단한 화학적, 물리적 특성을 파악하고 이의 활용가능성 여부를 알아보기 위해 수행되었다. Holocellulose 함량은 건조중의 74-88.5%로서 박주가리 종자섬유가 가장 높았고 전체적으로 큰부들 줄기의 것(59.5%)보다 높은 경향이었다. 그러나 holocellulose에 대한 alpha-cellulose의 비율은 45-48%로서 종자섬유간 서로 비슷하였다. |
