Abstract

Process and apparatus for shaping fibre-forming materials, made from a homogeneous isotropic or anisotropic, single- or multi-phase liquid multi-component system, in such a manner that the liquid multi-component system is extruded through spinneret holes into a pressurised liquid, that the liquid is moved in the direction of extrusion in a channel system which is formed from sections of constant and/or slightly tapering cross-section, and that the flow velocity of the liquid is correspondingly increased. <IMAGE>
