Abstract

<PICT:0605612/IV(a)/1> In a dry-spinning apparatus for the production of artificial filaments, the evaporative atmosphere travels in a closed circuit comprising, in the direction of travel, an evaporating chamber in which the filaments are produced, a cooling chamber situated beyond the point of emergence of the filaments, and a heating chamber which is in communication with the evaporating chamber, these successive chambers being connected with one another without any constrictions, and without any means for accelerating or slowing up the circulation of the gas or vapour. The gas or vapour which circulates in the direction of the filaments moves with the same speed as the movement of the filaments, the motion of the gas or vapour being caused solely by mechanical entrainment by the movement of the filaments. As shown, the left-hand side of the upper part of tube 1 is used as the evaporative chamber of the dry spinning cell. The spinning-solution is extruded through nozzle 6, and the filaments are removed from the side of the tube after passing round roller 7. A heating jacket 2, through which steam is circulated, surrounds the evaporative chamber. The lower part of tube 1 on both sides is provided with cooling jackets 3, 4, for circulation of cold brine. Condensed solvent is removed through vent 9. The chamber for reheating the circulating gas is formed by the upper right-hand portion of the tube 1 which is provided with a heating jacket 5 through which steam is circulated. The apparatus may be used for the production of cellulose acetate or synthetic resin filaments. Specifications 605,584 and 605,597 are referred to.
