Conclusions

The stress in polyacrylonitrile yarns of various chemical structures and of various linear densities has been studied under isometric heat-treatment under static and dynamic conditions.

Limits of the relaxation states have been determined over a wide range of temperature and rate (or duration) of yarn heating, in the contact and convective methods of heating.
