Definitions
- This invention relates to the production of artificial threads, filaments or the like by a dry spinning process in which a solution of I ther, it has been proposed to heat the spinning solution before the extrusion in order to reduce the viscosity of the said solution and also to enable the evaporation of the solvent to take placemore quickly. It has also been proposed to regulate the temperature in the neighbourhood of the spinning nozzle in a manner independent of the. temperature of .the remainder of the chamber or cell, and in this connection it has been proposed, on the one hand to maintain the nozzles at a low temperature, and on the other hand to effect a definite input of heat in the region of the spinning nozzles, for instance, by preheating the spinning solution on'its way'to the nozzle. In either of these latter'cases, however, the temperature maintained at the spinning nozzles, and in the zone immediately in their neighbourhood, is adjustable and variable, and is independent of the temperature of the remainder of thecell.
- the heating of the'spi'nning solution to l the same temperature as that fofftheairinl the spinning chamber according tothis in V vention can be effected according to various 'tion may pass through a pipe which traverses practically the whole-length of the" spinning chamber before it reaches the nozzle so thatasthe spinning solutionlpasses through th1spipe,'it gradually attains' the same temperature as that of the. air i'n the 75 adjacent to the nozzle; or the pipe'th rough which the spinning solutionpasses may take the form of a coiled pipe or a spiral situated at the upper end of the'spinning chamber adjacent to the/nozzle; or the pipe through which the spinning solution passes maybe led through the hot water jacket surrounding the spinning chamber thence pass to the spinning nozzle.
- the sald sp innlng chamber being surrounded by a jacket 6 and so arranged that hot water can be circulated in the space between B and C, entering by the pipeD, and leaving by the pipe E. 'ln'Fi'gurel, the-top part of the spinning chamber is shown as a hollow space,
- the spinning solution passes through a coiled or spiral pipe L situated in the upper part of the spinning chamber adjacent to the spinning nozzle A.
- threadsof greater lustre and free--- dom from glitter can be obtained by employwill be a maximum common temperature at .i which it is possible to obtain continuous filaments; above this maximum temperature either for the reason that the evaporation of the solvent takes place too rapidly or for some other reason, the spinning. of a continuous I have further ing a common temperature at or approaching the said maximum temperature.
- the spinning solution fandl'theevaporating atmosphere.
- Apparatus for the spinning of artificial threads, filaments and the like by a dry spinning process comprising a spinning chamber provided with a heating jacket in combination with a spinning nozzle having a supply pipe which is heated from said heating jacket for a considerable distance leading up to the nozzle sufiicient to cause the temperature of the solution as it leaves the spinning nozzle to be practically the same as the temperature of the atmosphere surrounding the nozzle.
- Apparatus for the spinning of artificial threads, filaments and the like by a dry spinning process comprising a spinning chamber provided with a heating jacket in combination with a spinning nozzle having a supply pipe traversing practically the whole length of the spinning chamber on its way to the spinning nozzle.
- Apparatus for the spinning of artificial 7 threads, filaments and the like by a dry spinning process comprising a spinning chamber provided with a heating jacket in combination with a spinning nozzle having a supply pipe coiled within the heated spinning chamber.
- Apparatus for the spinning of artificial threads, filaments and the like by a dry spinning process comprising a spinning chamber provided with a heating jacket in combination with a spinning nozzle having a supply pipe passing through the said jacket on its Way to the nozzle within the chamber.
