Features

Heating method: screw extruder is heated by electric heating ring, spinning box melt tube jacket is heated by biphenyl vapor phase external circulation.

Screw extruder adopts two-stage high-precision gear rotation, AC frequency conversion speed regulation, good stability, high pressure control accuracy and low noise.

Screw metering area with a special form of mixing head, melt pipe with static mixer, mixing more uniform.

The discharge head is equipped with temperature measuring and pressure measuring points for automatic recording, display, alarm and control.

Spinning machine metering pump drive using frequency converter-synchronous motor drive, note metering pump frequency conversion drive, accurate and reliable and can be started and stopped independently.

Electric heating type cooling device and superheated steam injection device are arranged below the spinneret plate, so that the temperature control precision is high.

Tow cooling adopts lateral blowing, tow oiling adopts crevice type, oiling transmission adopts frequency conversion driving.

Tow drafting uses yarn separating roller, feeding roller and four pairs of drafting rollers. The transmission control system adopts Swiss Rieter products with reliable precision.

Winding head of Swiss Textile (Rieter) company is adopted, its main drive is controlled by frequency conversion, and the action control is completed by PLC.

The computer monitoring system can monitor and manage the process flow, realize automatic data acquisition, dynamic display of process parameters, real-time measurement and recording, historical data storage and print output.
