摘要: 以碱性离子液体[MMIM]DMP 为溶剂,采用红外光谱和原料成分分析等手段研究再造烟叶原料烟梗经离子液体提取后表面形态、打浆及抄造性能的变化. 结果表明:烟梗经碱性离子液体提取后,原料表皮组织出现少量的蜂窝状结构,纤维细胞间的填充物质明显减少,孔隙增加;烟梗中的芳香类物质及木质素能较好地溶于碱性离子液体中,原料中纤维素相对含量明显增加;脱除部分木质素后的烟梗原料打浆后纤维的分散程度较好,打浆性能明显改善,抗张强度可提高 35%左右,抄造性能明显改善,松厚度和透气度指标得到了优化.

关键词: 烟梗, 纤维形态, 打浆性能, 抄造性能, 碱性离子液体

Abstract: This paper deals with the fiber morphology,beating performance and papermaking performance of tobacco stem (a kind of reconstituted tobacco raw material) after the extraction with alkaline ionic liquid[MMIM]DMP by means of IR and component analysis.The results show that (1) after the extraction with [MMIM]DMP,a small amount of honeycomb structure may occur in the epidermal tissue of tobacco stalk,and the filler among fiber cells decreases significantly,while the porosity increases; (2) as the aromatic substances and lignin in tobacco stems dissolve well in the alkaline ionic liquid,the relative content of cellulose in the raw material remarkably increases; and (3) the tobacco stem after partial delignification is of uniform fiber dispersion,good beating and papermaking performances,high tensile strength (with an increment of 35%) as well as optimized bulk and porosity parameters.

Key words: tobacco stem, fiber morphology, beating performance, papermaking performance, alkaline ionic liquid
