Surface modified PALF is introduced for making machinery parts like belt cord, conveyor belt cord, transmission cloth, air-bag tying cords, and some cloths for industry uses [157]. PALF is being used as a reinforced agent in polyropylene matrix in the palce of pure resin, to improve the mechanical properties. These properties are suitable for its application as building and construction materials, automotive components, and furniture. The process allowed close control of color, transparency, thickness and texture. The matrix is important to protect the fibers from Li, M.; Cheng, Y.L. Cross-linkage agents are used to improve the properties of biocomposites by improving the filler matrix interaction and filler dispersion. R. M. Heinicke and W. A.
