Title: Process for producing filaments from a liquid raw material which may be solidified by the action of liquid or gaseous media
IPC: D01D5/00
Filed: 1935-05-16
Abstract: <PICT:0441440/IV/1> In a process for producing filaments from a raw material which becomes solid under the action of liquid or gaseous media, the material e is passed through a tubular body a whose walls are porous to a liquid or a gas, if necessary under pressure, and the active medium c is passed through the porous walls of the tubular body, if necessary under a higher pressure, e.g. that of the column b<1> and is so caused to react upon the raw material, whereby the solidification or definite shaping of the raw material is effected on its passage through the tubular body.  The formed filament f may be passed after leaving the tube through a medium to complete solidification.  The thickness of the filament depends on the composition of the raw material and the bore of the tube a.  Suitable raw materials are latex dispersions to be coagulated, e.g. by organic acids, or polymerization products such as phenol-aldehyde resins coagulable by acids, or glue like materials may be used, the solidifying agent being an aldehyde, e.g. formaldehyde.
