Acrylonitrile spinning solution and process for producing fibers therewith.

摘要

@ A spinning solution for acrylonitrile polymers is disclosed, comprising an acrylonitrile polymer having a reduced viscosity of not less than 2.0, a solvent, and water, wherein the water concentration and the polymer concentration fall within the range in the drawing surrounded by straight lines connecting point A (1 wt% and 30 wt% respectively), point B (1 wt% and 10 wt% respectively), and point C (10 wt% and 10 wt% respectively). The spinning solution exhibits satisfactory spinnability in spite of its high polymer concentration and provides void-free acrylonitrile fibers having a highly circular cross-section and excellent mechanical strength.
