Abstract:

In order to reduce the preparation cost of existing polyacrylonitrile (PAN) fiber and achieve high value utilization of lignin, different proportions of lignin were used to prepare the lignin/PAN fibers employing the wet spinning process based on the understanding of viscosity of lignin/PAN blending solution, and the results from this work were used to identify the optimal spinning process. The structure and properties of the composite fibers were investigated by scanning electron microscopy, differential scanning calorimetry/thermal resynchronization analyzer, single fiber physical property analyzer, and UV-visible spectrophotometer. The results show that the lignin/PAN fiber with 35% lignin remains a uniform and dense structure, and its strength can reach 3.81 cN/dtex. After the addition of lignin, the synergistic effect of the two gives the composite fiber good thermal stability. The composite fiber has important potential application value in the fields of low cost carbon fiber and functional textile materials.

Key words: lignin/polyacrylonitrile composite fiber, wet spinning, spinnability, viscosity
