Wood Cellulose Fiber

PRODUCTION DESCRIPTION：
Cellulose fibers are fibers made with ethers or esters of cellulose, which can be obtained from the bark, wood or leaves of plants, or from other plant-based material. In addition to cellulose, the fibers may also contain hemicellulose and lignin, with different percentages of these components altering the mechanical properties of the fibers. The main applications of cellulose fibers are in the textile industry, as chemical filters, and as fiber-reinforcement composites, due to their similar properties to engineered fibers, being another option for biocomposites and polymer composites. Another main application is in the brake industry. Owing to water absorption characteristic and three-dimensional structure, the water inside can be transferred to the surfaces or interfaces of friction products quickly, which makes the bond strength and surface strength significantly increased. Its wood fiber dimensional stability and thermal stability contribute to stabilizing the coefficient of friction for friction materials.
