木质素纤维是天然木材经过化学处理得到的有机纤维，外观为棉絮状，呈白色或灰白色。通过筛选、分裂、高温处理、漂白、化学处理、中和、筛分成不同长度和粗细度的纤维以适应不同应用材料的需要．由于处理温度高达250℃以上，在通常条件下是化学上非常稳定的物质，不为一般的溶剂、酸、碱腐蚀，具有无毒、无味、无污染、无放射性的优良品质，不影响环境，对人体无害，属绿色环保产品，这是其它矿物质素纤维所不具备的。纤维微观结构是带状弯曲的，凹凸不平的，多孔的，交叉处是扁平的，有良好的韧性、分散性和化学稳定性，吸水能力强，有非常优秀的增稠抗裂性能。

Lignin fiber is a natural wood fiber obtained by organic chemical treatment, the appearance of cotton wool, white or grey white. Through screening, separation, heat treatment, chemical treatment, neutralization, bleaching and sieved into different length and thickness of the fiber to be applied to different materials. Due to high temperature above 250 degrees under normal conditions are very stable chemical substances, not as a sort of solvent, acid and alkali corrosion with excellent quality, non-toxic, tasteless, no pollution, no radiation, no influence on the environment, harmless to the human body, which is green environmental protection products, this is the other mineral fibres do not have. Fiber microstructure is band bending, uneven, porous, the intersection is flat, has good toughness, dispersion and chemical stability, water absorption ability, have very good thickening and anti cracking performance.
