For the natural fiber, uses the high-grade natural lumber, after project screening, the fission, the high-temperature treatment, chemistry processing, neutral, the decomposition contains the inert organic textile fiber which the lignin and the majority of textile fibers, remains down to form one kind of fiber structure chain, then sieves the different length and the granularity textile fiber meets the different application material need. Because the processing temperature reaches as high as above 260, under the usual condition is in chemistry the extremely stable matter, for the common solvent, the acid, the alkali does not corrode, has non-toxic, tasteless, does not have the pollution, the non-radioactive good quality, does not affect the environment, is harmless to the human body, is the green environmental protection product, this is other mineral innate nature textile fiber does not have. Textile fiber surface concave-convex rough, has the good toughness, the dispersivity and the chemical stability, infiltration capacity, has the extremely outstanding anti-crack enhancement performance. In the friction material use, is advantageous in reduces the friction material the proportion and may reduce the textile fiber the amount used. The wood fiber directly carbonizes, the carbides powder about 250 degrees Celsius which produces distributes in the friction material surface, plays role which lubricates touches steadily, and reduced the friction material hot decline to have adsorbability ultra, the enhancement effect obvious disperser, the intensity is high.
