In this method, bamboo is pretreated with chemical substances to dissolve the lignin, glia, and hemi-cellulose and to weaken the binding force between fibers. The fibers are then formed by mechanical external force. Deshpande introduced a chem­ical mechanical processing system, which can extract the bamboo fiber. It combines traditional techniques to molding grinding processes. The extracted bamboo fiber can be used for processing of isotropic composite material. This method has low fiber rate, requires more chemicals, fiber has a certain pH, and the process is com­plex and costly (Yao and Zhang 2011; Deshpande et al. 2000).

The above-mentioned method of production of bamboo fiber can be used as strengthening method to make a variety of composite materials. The products are further developed, and bamboo fiber produced in these methods cannot be used for weaving (Yao and Zhang 2011).
