| titleOfInvention | Preparation method of polyacrylonitrile fiber |
| abstract | The polyacrylonitrile fiber is prepared by swelling and dissolving polyacrylonitrile in a certain proportion of ionic liquid and high-boiling point (150-190 ℃) solvent under the conditions of high temperature and high pressure, then adding volatile or low-boiling point (30-60 ℃) solvent to obtain homogeneous spinning solution, then spinning, drawing and opening the fiber, and the polyacrylonitrile fiber is not easy to wrap the solvent in the fiber, so that the fiber defects are improved; the prepared fiber has the technical effects of being more compact and thinner in diameter. |
