Conclusions

The shrinkage of polyacrylonitrile fibres in air at 130–170°C, and also in steam or boiling water is connected with the formation of ordered structures due to a redistribution of the interacting CN groups.

Shrinkage of fibres in air at temperatures below 130°C is caused only by disorientation of the macromolecule chains.
