ABSTRACT OF THE DISCLOSURE: A process for the manufacture of texturized continu- ous filaments from synthetic linear high molecular weight substances by means of heated fluid media, wherein, between a filament inlet zone and a filament guide zone, the filaments are subjected, in a first treatment zone, to the action of a gaseous turbulent fluid heated medium and are thereby heated to a temperature at which they become semi-plastic and are trans- ported by the turbulently flowing medium through the first treatment zone. Then, in a second treatment zone, they are passed first through a cylindrical zone from which the medium can in part escape radially, and subsequently through a slight- ly conically flared zone from which the medium can also escape laterally. The speeds of the fluid medium and the filament are selected to be such that the ratio of the residence time of the filament in the cylindrical zone to the residence time in the conically flared zone is from 1:19 to 4:1, preferably from 1:9 to 1:2. And an apparatus to carry out the above process.
