1. Types of Nonwoven Fabric and Breathability
Nonwoven fabrics include spunbond, meltblown, needle-punched, thermally bonded, laminated, and composite fabrics. Each type has different air permeability characteristics.

|---|---|---|---|---|---|
| Spunbond | PP, PE | 40–150 | 300–800 | High | Medical masks, gowns |
| Meltblown | PP | 20–80 | 50–200 | Moderate | Filters, protective layers |
| Needle-Punched | PET, PP | 80–300 | 100–400 | Moderate-High | Diapers, mattress covers |
| Thermally Bonded | PP | 50–120 | 200–500 | High | Disposable sheets, apparel |
| Laminated | PP + PE Film | 70–180 | 20–150 | Low | Waterproof bags, protective suits |
| Composite | PET + PP | 100–250 | 150–400 | Moderate | Industrial and medical use |
| Recycled Fiber | PET Regrind | 80–200 | 100–350 | Moderate | Eco-friendly disposable products |
Procurement teams must evaluate “Is nonwoven fabric breathable” according to fiber type, GSM, and production method.
2. Factors Affecting Breathability
Breathability is influenced by:
-
Fiber Diameter – Finer fibers can reduce air passage.
-
Fabric Density (GSM) – Higher GSM lowers permeability.
-
Layering and Lamination – Additional layers reduce breathability.
-
Surface Treatment – Waterproofing or coatings can reduce airflow.
-
Fabric Structure – Needle-punched vs. thermally bonded affects porosity.
Table 2: Factors Affecting Breathability
| Factor | Influence on Breathability | Notes |
|---|---|---|
| Fiber Diameter | Fine fibers → lower | Meltblown fabrics have lower air flow |
| GSM | Higher GSM → lower | Heavy fabrics block airflow |
| Lamination | Reduces | Waterproof lamination reduces air passage |
| Surface Coating | Reduces | Hydrophobic or barrier coatings |
| Fabric Structure | Depends | Needle-punched → more porous, thermally bonded → smoother |
3. Breathability Testing Methods
Air permeability tests are standardized for quality assurance:
Table 3: Breathability Testing Methods
| Test Method | Unit | Description | Typical Benchmark |
|---|---|---|---|
| ASTM D737 | L/m²/s | Measures airflow under constant pressure | 100–800 for breathable fabrics |
| Gurley Method | s/100 mL | Time taken for air to pass through a fabric | 10–100 s for nonwoven |
| Water Vapor Transmission Rate | g/m²/day | Measures moisture vapor permeability | 50–300 g/m²/day |
| Air Resistance (Pa) | Pa | Differential pressure method | 20–200 Pa for medical fabrics |
Testing ensures materials meet “Is nonwoven fabric breathable” requirements for specific applications.
