Abstract 1. A METHOD OF SPINNING A SOLUTION CONTAINING POLYMER DISSOLVED IN A SOLVENT THEREFOR, INTO FIBROUS FILAMENTS FROM A SPINNERET, COMPRISING THE STEPS OF EXTRUDING SAID POLYMER SOLUTION FROM SAID SPINNERET, PASSING SAID EXTRUDED POLYMER SOLUTION THROUGH A FIELD OF GASEOUS MEDIUM HELD AT SUBATMOSPHERIC PRESSURE, INTO WHICH A PORTION OF SAID SOLVENT IS REMOVED FROM SAID POLYMER SOLUTION, CONTINUOUSLY SUPPLYING GASEOUS MEDIUM TO SAID FIELD AND SIMULTANEOUSLY EXHAUSTING GASEOUS MEDIUM CARRYING SAID SOLVENT THEREFROM AND THEREAFTER PASSING SAID REMAINING POLYMER SOLUTION INTO A LIQUID COAGULATING BATH AND COAGULATING SAID REMAINING SOLUTION TO FORM FILAMENTS, SAID FIELD OF GASEOUS MEDIUM BEIND MAINTAINED AT A PRESSURE LESS THAN THAT OF SAID LIQUID COAGULATING BATH AND WHILE AT LEAST PART OF THE SURFACE OF SAID COAGULATING IS IN DIRECT CONTACT WITH SAID FIELD OF GASEOUS MEDIUM THE LEVEL OF THAT PART OF THE SURFACE OF SAID COAGULATING BATH BEING DEPENE DENT ON THE PRESSURE OF SAID GASEOUS MEDIUM THEREON.
