What Is Meltblown Nonwoven?
Direct Answer
Meltblown nonwoven is a fabric made from very fine melt-extruded fibers, offering softness, filtration and barrier properties, used in SMS composites and premium layers.
Key Takeaways
- Meltblown nonwoven is a fabric made from very fine melt-extruded fibers, offering softness, filtration and barrier properties, used in SMS composites and premium layers.
- How it works: Meltblown extrudes polymer through fine nozzles into ultra-fine fibers (1-5 microns) that bond into a soft, dense web.
- SMS nonwoven sandwiches a meltblown barrier between spunbond layers for leak-proof cuffs
- Myth: Meltblown is weaker so it's low quality. It is engineered for softness and barrier, not strength — different purpose
How Meltblown Nonwoven Works
Meltblown extrudes polymer through fine nozzles into ultra-fine fibers (1-5 microns) that bond into a soft, dense web. It provides filtration and liquid barrier, and feels very soft. In hygiene products it appears inside SMS (spunbond-meltblown-spunbond) composites for barrier layers and in premium soft covers.
Examples and Applications
- SMS nonwoven sandwiches a meltblown barrier between spunbond layers for leak-proof cuffs
- Premium diaper soft covers use meltblown layers for plush feel
Meltblown Nonwoven vs. Related Terms
| Term | What it is | Key difference |
|---|---|---|
| Spunbond nonwoven | Meltblown Nonwoven | Spunbond is strong/structural; meltblown is fine/soft/barrier. SMS combines both |
Limitations and Common Misconceptions
- Myth: Meltblown is weaker so it's low quality. It is engineered for softness and barrier, not strength — different purpose
- Myth: Meltblown is only for masks. It is widely used in hygiene barriers and soft layers
What is meltblown nonwoven used for?
Barrier layers in SMS composites, filtration media, and soft premium layers in hygiene products.
Why is meltblown used in diapers?
Its fine fibers add softness and act as a liquid barrier inside multi-layer composites.
