Increasing the property uniformity of polyacrylonitrile fibres by adding water to spinning solutions

Fibre Chemistry Aims and scope

Conclusions

  • Additions of water to spinning solutions of an acrylonitrile copolymer in dimethylformamide increase the rate and temperature for their gelation.

  • In spinning from such solutions, the process of fibre solidification takes place by two mechanisms — a diffusion mechanism and a “cooling” mechanism.

  • Addition of water to the spinning solution shifts the solidification process in the direction of the “cooling” mechanism, which leads to obtaining a more uniform and better oriented fibre.
