Abstract

See full text

A method for stabilizing threads made of polyacrylonitrile using chemical stabilization reactions, comprising the following steps: provision of a polyacrylonitrile precursor wire, provision of an application device for the treatment of the precursor wire using high frequency electromagnetic waves, comprising an applicator with an application space, means for generating high frequency electromagnetic waves, as well as means for supplying high frequency electromagnetic waves in the application space, generating a field of high frequency electromagnetic waves in the application space , which has areas with minimum force and areas with maximum electric field strength, and adjustment of the maximum electric field strength in the range of 3 to 150 kV / m, thereby continuously transporting the precursor wire through the application space and across the field of electromagnetic waves d At high frequency, transport a process gas through the application space with a flow rate of at least 0.1 m / s in relation to the precursor wire, where the temperature of the process gas is set in the interval between 150 and 300 ° C, so that it is above a critical minimum temperature and below a maximum temperature.
