The technical requirements of POY spinning testing machine usually include the following aspects:

1. Precision of spinning process parameter control

- Precise control of screw extrusion temperature, temperature fluctuation range is small, to ensure the uniformity and stability of the melt.

- High precision of metering pump speed control to ensure accurate metering and output of spinning fluid.

- Side blowing wind The wind speed, temperature, humidity and other parameters are stable and can be adjusted accurately.

2. Spinning component performance

- The structural design of the components is reasonable, which can evenly distribute the spinning fluid, reduce the hair and broken ends.

- Good filtering effect to remove impurities and prevent blockage of spinneret holes.

3. Quality of spinneret

- High uniformity of shape, size and distribution of spinneret holes to obtain high-quality primary fibers.

- The spinneret material has good wear resistance and corrosion resistance.

4. Drafting system

- High speed control precision and wide speed range of draft rollers to adapt to different spinning process requirements.

- Precise adjustment and stable control of draft ratio.

5. Winding system

- The winding speed is stable, the rolling molding is good, and there are no defects such as collapsing edge and convex shoulder.

- Precise tension control to avoid excessive stretching or relaxation of the thread.

6. Degree of automation

- Complete automatic control system, which can monitor and record the parameters in the spinning process in real time.

- With fault alarm and self-diagnosis function, easy to deal with problems in time.

7. Safety protection device

- Equipped with overload protection, overheat protection, emergency stop and other safety devices to ensure the safety of operators and equipment.

8. Equipment stability and reliability

- Long-term stable operation, low failure rate, easy maintenance and maintenance.

9. Environmental adaptability

- Can work normally within a certain temperature and humidity range, and is not sensitive to environmental changes.

10. Data acquisition and analysis function

- Ability to accurately capture and store data during the spinning process, as well as data analysis and processing capabilities to support process optimization.
