New chain cellulose together and forms subfibril. Subfibril is around 1.5nm wide which belongs to the thinnest natural fibers [5]. cellulose subfibril is crystallized as microfibril (bundle) and then turns into ribbons (clot-bound) [6]. Table 1 shows that the resulting
The width of cellulose fiber pulp produced by birch or pine is greater, respectively 1.4 - 4.0 × 10-2 and 3.0 - 7.5 × 10-2 mm. The length of very thin ribbons of cellulose is about 1-9 ìm which forms a dense reticulated structure being stabilized by hydrogen bonds [6] Figure 3 shows different cellulose structures formed naturally from the extra- cellular bacteria and plants. Ribbons are formed at cellulose structure to strengthen the structure of the
resulting biocellulose. Cellulose structure in natural vegetation is formed linearly without having any ribbon formation.
