The working principle of PP Spunbond machine mainly includes the following steps:
1. Plasticizing polypropylene raw material. The polypropylene particles are melted into a homogeneous melt by stirring and heating, and then filtered to remove impurities.

2. Melt spinning. The PP Spunbond machine manufacturer tells you to extrude the melt through the spinneret die hole of the Spinbeam unit and spin it into multiple continuous polypropylene tows. The diameter and hole density of the spinneret die hole determine the thickness of the tow and the spacing between the tow.
3. Cationization of the tow. The spun tow is passed through a high-speed rotating cation nozzle, and a high-pressure ion airflow is sprayed to realize the cation treatment of the tow. The cationic tow becomes a non-woven structure under natural tension.
4. The non-woven fabric is formed into a web. The PP Spunbond machine manufacturer tells you that the cationized tow is deposited and formed on the prepared drum, and a non-woven network structure is formed through mechanical bonding (mainly entanglement and bonding between fibers). The steps determine the basis weight and performance of the product.
5. Subsequent processing. The non-woven fabric is made into a finished non-woven fabric through subsequent processes such as calendering, drying, coiling, and rewinding. Non-woven products with different properties can also be produced through other subsequent processes such as PEG coating and printing.
6. Roll making and packaging. The finished non-woven fabric is made into rolls, packaged, and shipped out of the factory for customer use.
To sum up, PP Spunbond machine processes polypropylene raw materials into non-woven products through a series of processes such as melt spinning, tow cationization, non-woven web forming and subsequent processing. This series of technological processes forms the basis of the working principle of the entire production line.
