Conclusions
It has been shown that in the continuous orientation stretching of Oksalon yarn in air, the deformation region is located close to the first stretch roll, including an arc of yarn slippage on it.
The need to take the slippage arc into account in continuous yarn stretching has been demonstrated.
By varying the frictional parameters of the first stretch roll, it is possible to achieve an increase in the strength of the finished yarn.
