ABSTRACT:
An apparatus includes a spinning nozzle, a fiber drawing device and a water spray device. The spinning nozzle has spinnerets and a spinning solution is filled therein. The spinning solution includes a solvent and a fiber material. The solvent includes N-Methylmorpholine N-Oxide, and the fiber material includes cellulose. The fiber drawing device is disposed under the spinning nozzle and has a gas flow generating device therein for generating a gas flow which is ejected from the top of the fiber drawing device and toward the bottom thereof. The fiber drawing device also has a slit on the top thereof, and the spinning solution from the spinning nozzle would enter the fiber drawing device through the slit. The water spray device is disposed at the slit of the fiber drawing device, and the spinning solution would pass through the water spray device before entering the fiber drawing device.
