Spinning apparatus and spinning method

A method of spinning a filament by a dry spinning, comprising:

• extruding a spinning dope from a plurality of spinneret holes of a spinneret positioned at an upper end side of a spinning cabinet, into an interior space of the spinning cabinet which extends in a vertical direction;
• supplying a first gas from above the spinneret to the interior space, allowing the first gas to come into contact with the spinning dope passing through the plurality of spinneret holes;
• and
• supplying a second gas having a higher temperature than that of the first gas from below the spinneret to the interior space, allowing the second gas to come into contact with the spinning dope extruded from the plurality of spinneret holes,
• a supply amount of the first gas per unit time being less than a supply amount of the second gas per unit time,
• wherein the spinning of the filament is conducted by the dry spinning.

A method of spinning a filament by a dry spinning, comprising:

• extruding a spinning dope from a plurality of spinneret holes of a spinneret into an interior space of a spinning cabinet;
• supplying a first gas at a first temperature and a first gas supply rate, into the interior space of the spinning cabinet, from a first supply position above the spinneret, into contact with the spinning dope passing through the plurality of spinneret holes;
• and
• supplying a second gas at a second temperature and a second gas supply rate, into the interior space at a second supply location below the spinneret, into contact with the spinning dope extruded from the plurality of spinneret holes, the second temperature being higher than the first temperature and the first gas supply rate being less than the second gas supply rate,
• wherein the spinning of the filament is conducted by the dry spinning.
