Are nonwoven fabrics waterproof?
Nonwoven fabrics are very common in life, not only in the field of construction, but also in clothing, medical and other fields.
The nonwoven fabric is not waterproof, not only that, it also has a certain permeability, if no other treatment is done, the water will penetrate directly. If you want to make the nonwoven fabric have a waterproof effect, you can cover the surface with a film, or add a layer of PVC material on the surface, so that you can achieve waterproof, moisture-proof and oil-proof effects.
