Along with cellulose, one of the imperative constituents of natural cellulosic fibers is hemicellulose and is the second most abundant family of naturally occurring polymers (Thakur and Singha, 2013 and Thakur, 2013). Hemicelluloses are buildup of a combination of 5- and 6-ring carbon ring sugars (Fig. 2 b).
