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 an organic fiber obtained by chemical treatment of natural wood. Its appearance is cotton wadding, white or gray white. Through screening, splitting, high temperature treatment, bleaching, chemical treatment, neutralization and screening, fibers of different lengths and thicknesses are separated to meet the needs of different application materials. Due to the treatment temperature as high as 250 ℃, it is a very stable chemical substance under normal conditions. It is not a common solvent, acid and alkali corrosion, and has non-toxic, tasteless, pollution-free, non radioactive excellent products Quality, does not affect the environment, harmless to human body, is a green environmental protection products, which other mineral fiber does not have. The microstructure of the fiber is banded, curved, uneven, porous and flat at the intersection. It has good toughness, dispersion and chemical stability, strong water absorption capacity and excellent thickening and crack resistance.
