| Abstract: | Conclusions -- A procedure has been developed for calculating the specific volume of the flowing zone of fibre in spinning from the melt.-- The unequivocal connection between the specific volume of the flowing zone of spun fibre and the strength of the final fibre from pitches indicates that to attain higher strength, it is necessary to create more  severe conditions for fibre cooling.-- It has been found that fibres from pitches with a softening point above 200°C are more sensitive to fluctuations in parameters of the spinning process.VNIIPV.
