Lignocellulosic fibers dimensions

Table 2 Dimensions of Some Common Lignocellulosic Fibers...

On the other hand, lignocellulosic fibers are never perfect cylinders. Furthermore, they possess naturally nonuniform shape and dimensions, particularly at their cross sections. Even if an average equivalent diameter is considered, UgnoceUulosic fibers display significant changes in diameters from one fiber to another as well as... 

There are undoubtedly numerous chemical pre-treatment methods used in the literature for the isolation of cellulose fibers from different lignocellulosic sources. The choice of these chemical treatment methods is influenced by the properties of lignocellulosic materials such as their chemical composition, internal fiber stmc-ture, microfibril structure, microfibril angle, cell dimensions and the defects which are in return influenced by the type and the sources of the lignocellulosic materials (Siqueira et al., 2010). The intended use of the cellulosic fiber product could also have an influence on the choice of chemical treatment method (Dufresne et al., 2008). The schematic diagram showing different pre-treatment methods during cellulose isolation are depicted in (Fig 3.11).
