Different classifications of spinning machines
A spinning machine is a machine that makes a fiber-forming polymer solution or melt form filaments.
(1) According to different fiber spinning methods, spinning machines are divided into three types: wet spinning machine, melt spinning machine, and dry spinning machine.
(2) According to different fiber types, there are filament spinning machines and short fiber spinning machines.
The melt spinning machine is composed of screw extruder, spinning box, spinning window, spinning channel and winding machine. Screw and sleeve are important parts in screw extruder. The spinning pump and nozzle assembly are installed on the pump body in the spinning box. The spinneret in the spinneret assembly is the key part of the melt to form a trickle. If it is direct spinning, the screw extruder parts can be omitted.
It is characterized by high spinning speed and simple spinning process. Used in the production of polyester, cotton and polypropylene.
The filament spinning machine requires a certain package form for the post-processing of the thread, so the winding part is increased. Viscose filament spinning machines are divided into centrifugal and bobbin spinning machines according to different winding formations. At present, centrifugal tanks are mostly used for winding into silk cake.
It is characterized by low spinning speed, complicated spinning process and long process. Used in the production of acrylic fiber, vinylon and viscose fiber.
The structure of the dry spinning machine and the melt spinning machine are the same, the difference is: the dry spinning is a solution spinning process, there are processes such as pre-spinning preparation, the catheter sends the spinning dope to the spinning pump; the spinning chamber and The channel, the melting method is a cooling effect, and the dry method is to heat the channel and cool and recover the flux evaporated from the original liquid. The dry spinning speed is high and it is used in the production of acrylic fiber, chlorinated fiber, acetate and other filaments.

The wet spinning machine is composed of spinning pump, filter, catheter spinneret assembly, godet roller and coagulation bath.
