Both annual (cotton, flax, hemp, etc.) and perennial (trees and grasses) plants can serve as a source of cellulose for fiber production. In recent years, the perennial herbaceous plant miscanthus has attracted particular interest as a popular industrial plant with enormous potential. This industrial crop, which contains up to 57% cellulose, serves as a raw material in the chemical and biotechnology sectors. This study proposes for the first time the utilization of miscanthus, namely Miscanthus Giganteus "KAMIS", to generate spinning solutions in N-methylmorpholine-N-oxide. Miscanthus cellulose's properties were identified using standard methods for determining the constituent composition, including also IR and atomic emission spectroscopy. The dry-jet wet method was used to make fibers from cellulose solutions with an appropriate viscosity/elasticity ratio. The structural characteristics of the fibers were studied using IR and scanning electron microscopy, as well as via X-ray structural analysis. The mechanical and thermal properties of the novel type of hydrated cellulose fibers demonstrated the possibility of producing high-quality fibers from miscanthus.
一年生植物(棉花、亚麻、大麻等)和多年生植物(树木和草类)都可以作为纤维生产中纤维素的来源。近年来,多年生草本植物芒草作为一种具有巨大潜力的热门工业植物引起了特别关注。这种工业作物含有高达57%的纤维素,可作为化学和生物技术领域的原材料。本研究首次提出利用芒草,即巨芒草“KAMIS”,在N-甲基吗啉-N-氧化物中制备纺丝溶液。使用测定成分组成的标准方法确定了芒草纤维素的特性,其中还包括红外光谱和原子发射光谱。采用干湿法由具有适当粘度/弹性比的纤维素溶液制备纤维。使用红外光谱、扫描电子显微镜以及X射线结构分析研究了纤维的结构特征。新型水合纤维素纤维的机械和热性能表明了利用芒草生产高质量纤维的可能性。
