Rolling technology slices bamboo, which is then softened by steam so that lignin middle lamella separates out. The bonding of the fiber is then weakened through rolling or hammering. Through mechanical friction, bamboo is eventually decom­posed (Yao and Zhang 2011). Quality and yield of fiber produced by this method is shown in Table 2.1.

2.3.1 Mechanical Comb Fiber Technology

With the help of mechanical equipments, bamboo is ground to make bamboo fiber. Although the strength and flexibility of the fiber is considerably damaged during the mechanical treatment process but the fiber produced is thick and short and is used in the production of bamboo fiberboard and some other low value products (Yao and Zhang 2011) . Quality and yield of fiber produced by this method is shown in Table 2.1.

2.3.2 Degumming Defibrase System Technology by Explosion

As bamboo plant has high lignin content so it is difficult to perform degumming on it. Therefore, liquid water is taken and bamboo is treated at high temperature and pressure. Although this method is chemical and pollution free, has high fiber rate and uniform fiber recovery, but the process is intricate and costly and the fibers obtained are also dark colored (Yao and Zhang 2011). Quality and yield of fiber produced by this method is shown in Table 2.1.
