Suitable for spinning viscose fiber, acrylic fiber, vinylon, etc. The main feature is that the polymer solution is extruded from the spinneret and coagulated into nascent fibers in the coagulation bath. The spinning speed is low, usually below 100 m/min, and the high-speed spinning speed can reach about 200 m/min. Wet spinning machines are divided into short fibers and long fibers.

①Short fiber spinning machine: the spinning dope is introduced from the infusion tube, accurately measured by the metering pump, filtered by the filter into the spinneret, and extruded from the spinneret hole into the coagulation bath, and the nascent fiber is collected through the godet after coagulation The bundles are washed or stretched. The short fiber spinning machine is characterized by a large number of holes in the spinneret (plate), usually 3,000 to tens of thousands of holes.

②Filament spinning machine: Different from the short fiber spinning machine, the winding mechanism of the solidified thread is added. After being washed with water, the thread from the coagulation bath passes through the wire guide plate, and enters the high-speed rotating centrifugal tank through the reciprocating guide wire funnel. Such a spinning machine is called a centrifugal tank spinning machine; if the thread is wound on a bobbin through a godet, it is called a bobbin spinning machine; if there is a partial post-processing process before winding, It is called a semi-continuous spinning machine; if all procedures of spinning and post-processing are completed continuously on the spinning machine, it is called a continuous spinning machine. The production of viscose cords mostly uses continuous spinning machines. Spinnerets for filament spinning generally have 150 holes or less, and the number of holes for spinning cord fibers is up to 3000 holes.
