ABSTRACT
Cellulose is the most abundant material on Earth; it is the main constituent of plants, serving to maintain their structure, and it is also found in bacteria, fungi, algae, and even in animals. It is a natural polymer formed by β-D-glucopyranose linked by (1 → 4) glucosidic bonds [1,2]. The monomelic unit is formed by two glucosidic units linked as shown in Fig. 1. The conformational arrangements originated by the β( 1 →4) bonding and the possible crystalline arrangements may be considered as ideal in forming the fiber structures.
