The spunbond nonwoven production lines use polypropylene (PP) as raw material to make PP Nonwoven Fabric, adopting the technology of air drawing into webbing by negative pressure. The product of nonwoven series is usually applied for packaging, waterproof material, packaging base lining and so on.
The width of nonwoven fabric of Non-woven Fabric Line can be 1600mm, 2400mm, 3200mm, and 4200mm.
Advantages of spunbond nonwoven line:
1. It is easier and faster to change the color of nonwoven fabric and there is not too much waste nonwoven fabric during the period of changing color.
2. The land and space are less, the labor is less, and operation is easier.
