Let's talk about the drying process of chip spinning

1. Objectives and Requirements of Slice DryingMain Objectives:Remove Moisture: The moisture content of undried slices is about 0.4%. Moisture can cause intense hydrolysis of polyester macromolecules during high-temperature spinning, leading to a decrease in molecular weight (characteristic viscosity

Causes of Slurry Leakage in Spin Packs And Their Solutions

Factors related to sealing components (auxiliary materials):① Inappropriate material: The hardness of the sealing ring is crucial for deformation. If the hardness is too low (such as pure aluminum), it may undergo excessive deformation; if the hardness is too high (such as silicon-aluminum alloy), i

The conventional spinning process

The conventional spinning process is as follows: dry chips→ melt extrusion → mixing → metering → filtering → spinning → cooling and shaping → oiling → winding → UDY bobbin.
