ABSTRACT:
A process for texturizing bundles of filaments of synthetic high molecular weight materials at high speed, wherein the filament bundle is passed through a feed nozzle and is then brought into contact with a hot gaseous medium which is undergoing a vortical motion and has acquired a vortex angle of from 10.degree. to 70.degree. as a result of passage through a vortex chamber, is then heated by the fluid medium in a downstream tubular chamber and is subsequently fed to an expansion stage to produce the crimp, and apparatus for carrying out this process.
