Cellulose Fibers, either cotton particles or wood pulp, are steeped in a mixture of aqueous sodium hydroxide, rendering them alkali cellulose. Then it is pressed thin, ensuring that it maintains the correct balance between the alkali and cellulose. This is shredded into "crumbs", or fluffy particles, to give it greater surface area to be chemically treated. From there the cellulose is aged in a controlled environment until the molecules have combined to the desired degree.  non-environmental pollution, is a kind of green environmental protection material. It is the three-dimensional structure, can stabilize and reduce the material the contraction and the expansion, noise insulation, its chemical stability is good, may avoid the material corroding, Now it has widely used in braking materials, composite filling, if used for the clothing, has attracts the perspiration, deodorizes, functions and so on ventilation.
