摘要
红麻是国内外正在开发利用的制浆造纸新原料,本文利用扫描电镜、透射电镜和光学显微镜技术对红麻韧皮部和木质部的解剖学特性进行了较全面的研究,并论述了红麻的解剖学特征对制浆造纸性能的影响.
The anatomical characteristics of kenaf bast and core were studied by SEM,TEM and optical microscope,and the effects of anatomical characteristics on pulping and papermaking potentials of kenaf Were described.Results ob- served indicated that: Kenaf is a multicellular plant which has epidermis cell,libriform fiber cell,xylem fiber cell,parenchymatous cell,woodray cell,as well as pit vessels,spiral vessels and trapezoidal vessels etc.Fiber cell is the main cell. The fiber cellwalls of kenaf bast and woody fibers are composed of primary wall(P) and secondary wall(S). The secondary wall is divided into S_1,S_2 and S_3 layer,S_2 layer is the widest one and is not laminated,S_1 layer is thicker than S_3 layer in the hast fibers while S_1 layer is thinner than S_3 layer for woody cell. For kenaf bast fiber and woody fiber,microfiberil arrangement of primary wall shows much irregularity.How- ever,that of S_1 layer is cross spiral,and that of S_2 layer is unidirectional spiral. Distinct differences in tissue structures and fiber appearance exist between the bast fiber and the woody fiber. The bast fiber has a thicker wall with a small lumena,slender in appearance and with few pits.The woody fiber, however,has a thinner wall with a large lumena,stout in appearance and with more pits.Evidently,their responses to pulping and papermaking will be distinctly different.
