What Are The Production Processes And Technologies Of Polypropylene Fiber?
Jul 10, 2023| The Production Processes And Technologies Of Polypropylene Fiber
1. Raw material preparation
The raw materials of polypropylene fiber are mainly polypropylene particles, which also need to add some additives, such as plasticizers, antioxidants, light stabilizers, pigments, etc.
2. Melt and mix
The above raw materials are added to the melt mixer for mixing, and the mixed materials are heated to a molten state.
3. Spinning
The molten polypropylene material is stretched and processed by a spinning machine to form polypropylene fibers.
4. Traction and cooling
The spun polypropylene fibers are transported to traction and cooling units for processing.
5. Winding and cutting
The processed polypropylene fibers are wound onto rolls or cut to make products of different specifications.
