“…To improve hemp fibre quality additional refining procedures are required, i.e., cleaning the surface and splitting fibre bundles into finer units, ideally into individual fibre cells. For refining various methods may be adapted including steam explosion [11], ball milling of thermally treated fibres [12,13,14], chemical degumming in alkaline media [15,16], enzymatic separation of technical fibres, and scouring [17,18].…”

“…These fibers are usually found in the natural plants as the aggregates of multiple cells which are held together by so called gums such as lignin and pectin. The single fibers and fine fiber bundles can be extracted by totally or partially removing the gums, depending on the treatment conditions [5][6][7][8][9].…”

Fiber surface morphologies and associated internal structures are closely related to its properties. Unlike other fibers including cotton, bast fibers possess transverse nodes and fissures in cross-sectional and longitudinal directions. Their morphologies and associated internal structures were anatomically examined under the scanning electron microscope. The results showed that the morphologies of the nodes and the fissures of bast fibers varied depending on the construction of the inner fibril cellular layers. The transverse nodes and fissures were formed by the folding and spiralling of the cellular layers during plant growth.The dimensions of nodes and fissures were determined by the dislocations of the cellular layers. There were also many longitudinal fissures in bast fibers. Some deep longitudinal fissures even opened the fiber lumen for a short way along the fiber. In addition, the lumen channel of the bast fibers could be disturbed or disrupted by the nodes and the spirals of the internal cellular layers. The existence of the transverse nodes and fissures in the bast fibers could degrade the fiber mechanical properties; whereas the longitudinal fissures may contribute to the very rapid moisture absorption and desorption.
