Abstract

The invention relates to producing fibres from polyacrylonitryl (PAN) and the copolymers thereof (CPL) which can be used, for example for the textile industry and as technical fibres. Said invention makes it possible to produce PAN or CPL fibres whose molecular mass is equal or higher than 6 ∗ 104 g/mol and which have a tensile strength equal to or greater than 0.9 hPa and an elasticity modulus equal to or greater than 17 hPa by carrying out a known fibre production method which consists in dissolving PAN or the CPL thereof, forming a polymeric solution in the form of a fibre by passing it through a draw hole, jellying said solution, substituting the solution solvent by a polymer precipitator and in removing said precipitator associated with a subsequent elongation, and which is complemented by placing the solution, which passed the draw hole in the form of a fibre, on a receiving element surface in such a way that the fibre sections are separated from each other and, afterwards in simultaneously carrying out a jollification stage through the totality of fibre arranged on said receiving element.
