红麻纤维形态和化学组成的研究

对红麻进行测定的结果说明,韧皮部纤维细长,形状和结构与针叶木相似;而木质部纤维粗短;韧皮部的综纤维素含量高于木质部,而1％NaOH溶液溶出物、木质素和戊聚糖低于木质部。红麻的综纤维素主要由萄葡糖基和木糖基组成,韧皮部纤维可代替针叶木制造优质纸浆。

STUDIES ON THE FIBER DIMENSION AND CHEMICAL COMPONENTS OF HIBISCUS CANNABINUS

Fiber dimension and chemical components of xylem and phloem of Hibiscus cannabinus have been determined. Bastfibers are long and thin. They are similar to softwood in dimension and structure, xylon and short and thick, The content of holoccllulose in phloem is higher than in xylem but the contents of lignin, pentosan and dissolved matter in 1% NaOH are lower. Holocellulose is mainly composed of glucosyl and xylosyl. Glucosyl centent of holocellulose in phloem is higher than in xylem, conversely xylosyl is lower. Bastfiber of Hibisucs cannabinus can replace softwood and be used for making high-quality pulp. The quality of pulp making from its xylon was estimated much worsl.
