Abstract
942,975. Melt-spinning artificial filaments. BRITISH NYLON SPINNERS Ltd. May 30, 1962, No. 20837/62. Addition to 901,398. Heading B5B. The process of the parent Specification (wherein in the melt-spinning of a synthetic linear polymer a homogeneous and laterally unconfined shallow layer of an inert gas such as steam, which may be superheated, is continuously and uniformly provided in contact with the entire surface of at least that portion of the face of the spinneret plate which contains the extrusion orifice or orifices) is modified in that the steam below the spinneret plate is provided substantially at atmospheric pressure and at a velocity just sufficient to maintain the required flow for blanketing the face of the spinneret plate. The steam may be metered from a single pressure supply thereof to a number of spinneret plates, and may be allowed to expand to substantially atmospheric pressure before it reaches the vicinity of the spinneret plates. A metering orifice within the steam supply pipe may be fitted at a position outside of the melt-spinning apparatus itself. The steam may be metered from a single pressure supply thereof to a number of spinning plates, and may be allowed to expand to atmospheric pressure before it reaches the vicinity of the plates. The metering orifice may be located at the inlet of a main steam header pipe supplying a number of melt-spinning apparatuses. The advantage of the modification of the invention of the parent Specification are the complete absence of any interference with filament flow owing to the low velocity of the steam at the spinneret face and that the gauze diffusor ring may be dispensed with and poor filament flows due to any partial blockage of the ring thereby avoided. " Wiping " of the spinneret face when " drip " occurs is also thereby facilitated.
