- Filters particles and infections
- Fragile if not coated
- Can be adjusted to absorb or repell liquids
Meltblown is quite fragile because the fibers are so thin and short, which also gives the material its unique properties: it can let through, for example, the air in a mouthguard – but not drops of liquid. It can also be used to let oil pass through but hinders small particles.
To prevent the material from breaking, meltblown is often coated with another type of nonwoven, such as spunbond, for stability and durability. Sometimes it is coated on both sides – so that the meltblown acts as a filtering core.
By coating meltblown or mixing its fiber with other materials, you can add different types of properties to the material such as making it both water-absorbent and water-repellent.
The material can be both super thin and thick – depending on which application area it is to be used in.
WHERE IS IT USED?
Wipes: it is used in different types of wipes
Face masks: As filter core in face masks used in healthcare and construction, In healthcare to filters out infections in saliva and air. In construction to filters out harmful particles from being inhaled.
Filtration: Since the material is so dense, it can filter out particles but still allow liquids, air or oil to pass through.
Absorption: By adding absorbent fibers or an absorbent carrier to the material, it can be used in various types of absorbents.
