Abstract:

The residual deformation adn fracture morphologies of kapok fibers were analyzed, and the surface morphologies of kabok fibers before and after removal of different compositions and riverting of the hollowness were observed. Based on these results, the main body structure, surface structure and material distribution of kabok fiber were summarized. It was found that strip units with width of 5 – 20 µm screw along the axial form the tube-like kapok fiber. The strup units are composed of fibrils (cellulose) , lignin and hemicelluloses mainly fill in the spiral seams between the strip umts. The spiral seams are the weak sections of the fiber and form fractures or folds when suffering large force or repeated small forces. Macro-fibrils with a certain size are arranged and woven neatly along the axial to form the thin surface structure of kapok fiber, with partial horizontal rings of a certain wudth in the surface.

Key words: kapok fiber, longitudinal structure, strip unit, screw, surface structure, maceo-fibril
