The drafting of a spinning machine wet spinning machine

Spinning (machine of chemical fibre) is a kind of machine that makes the polymer solution or melt. According to the method of fiber spinning, the spinning machine is divided into three types: wet spinning machine, melt spinning machine and dry spinning machine.

The drawing machine is suitable for viscose fiber, acrylic fiber, vinylon spinning. The main characteristic is that the polymer solution is extruded from the jet hole, and is made into the primary fiber in the coagulation bath, and the spinning speed is 100 m / min, and the speed of the high speed spinning is about 200 m / min. Wet spinning machine is divided into two kinds of short fiber and long fiber.

1. Staple fibre spinning machine: dope from the infusion tube into, is precisely measured by a metering pump, through the filter into the spinneret, from the spinneret hole extrusion trickle into the coagulation bath, after solidification as spun fiber through the guide wire disc sink integrated bundle after washed with water or stretching. The short fiber spinning machine is characterized by a large number of jet cap (plate) holes, usually 3000 to tens of thousands of holes.

Filament spinning machine: different from short fiber spinning machine is an increase of the winding mechanism. From the wire strip, which is washed out of the coagulation bath, after the guide wire, through the upper and lower reciprocating movement of the guide wire into the high-speed rotating centrifugal tank. Such spinning machine for tank centrifugal spinning machine; if the wire through the guide wire winding disc on the bobbin is known as a bobbin spinning machine; such as in front of the winding with part of the post processing step, called semi continuous spinning machine; if spinning and after processing all the processes are continuous in the spinning machine completed is called continuous spinning machine. Rayon cord production by continuous spinning machine. Spinning spinneret used generally in the 150 hole, spinning fiber cord hole and 3000 hole number.
