What is pack pressure and how it will maintain for specific denier and throughout .

Question

Accepted Answer

Pack pressure is the pressure applied to the polymer melt in the spinning pack during the fiber production process.

Pack pressure is crucial in determining the quality and properties of the final fiber product.
It is maintained by adjusting the screw speed and the size of the orifices in the spinning pack.
For a specific denier, the pack pressure should be optimized to achieve the desired fiber properties.
Throughout the production process, the pack pressure should be monitored and adjusted as necessary to ensure consistent quality.
Examples of factors that can affect pack pressure include polymer viscosity, temperature, and throughput rate.
