-
Soft, lightweight, and suitable for high-absorbency applications.
-
Degrades in 6–12 months under industrial composting conditions.
2.2 Polyhydroxyalkanoates (PHA)
-
Produced through microbial fermentation.
-
Soft, skin-friendly, and biodegrades faster (3–6 months).
-
Higher cost but ideal for premium sanitary products.
2.3 Cellulose-Based Nonwovens
-
Sourced from wood pulp or cotton linters.
-
Biodegrades within 2–4 months.
-
Moderate absorbency and high consumer appeal due to natural origin.
2.4 Bamboo Fiber Nonwovens
-
Very soft and moderately absorbent.
-
Biodegrades in 1–3 months.
-
Bamboo is fast-growing and renewable, offering a sustainable supply.

| Fabric Type | Absorbency (g/g) | Softness | Degradation Time | Cost ($/kg) |
|---|---|---|---|---|
| PLA | 6.5 | Medium | 6–12 months | 12 |
| PHA | 7.2 | Soft | 3–6 months | 15 |
| Cellulose | 5.8 | Soft | 2–4 months | 10 |
| Bamboo | 6.0 | Very Soft | 1–3 months | 11 |
3. Key Technical Parameters
Understanding technical specifications is vital for procurement professionals. The main parameters include absorbency, wet strength, vertical wicking, and air permeability.
3.1 Absorbency
High absorbency ensures comfort and reduces leakage. For sanitary pads, absorbency of 6–7 g/g is considered high-performance.
Table 3: Absorbency and Wet Strength
| Supplier | Fabric Type | Absorption Capacity (g/g) | Wet Strength (N) |
|---|---|---|---|
| A | PLA | 6.5 | 2.1 |
| B | PHA | 7.2 | 2.5 |
| C | Bamboo | 6.0 | 1.9 |
3.2 Vertical Wicking and Air Permeability
Proper wicking distributes moisture efficiently while maintaining skin dryness.
Table 4: Wicking Rate and Air Permeability
| Fabric Type | Vertical Wicking Rate (cm/s) | Air Permeability (mm/s) |
|---|---|---|
| PLA | 0.12 | 50 |
| PHA | 0.15 | 60 |
| Bamboo | 0.13 | 55 |
4. Production Methods
4.1 Spunlace (Hydroentangled)
-
High-pressure water jets entangle fibers.
-
Produces soft, strong fabrics suitable for premium sanitary pads.
4.2 Meltblown
-
Fibers extruded through fine nozzles.
-
High absorption, finer fiber distribution.
-
Higher energy usage and production cost.
4.3 Airlaid
-
Fibers dispersed and bonded via thermal or chemical methods.
-
Lower energy consumption, efficient for mass production.

| Method | Production Speed (m/min) | Energy Use (kWh/kg) | Material Waste (%) |
|---|---|---|---|
| Spunlace | 100 | 0.6 | 5 |
| Meltblown | 80 | 0.8 | 7 |
| Airlaid | 60 | 0.5 | 4 |
5. Cost Analysis and Procurement Strategy
While biodegradable nonwoven fabrics have higher raw material costs than conventional PP nonwovens, their eco-friendly properties and consumer appeal justify the investment. Procurement teams should consider total cost, supplier reliability, and market demand.
Table 6: Cost and ROI Comparison
| Fabric Type | Material Cost ($/kg) | Manufacturing Cost ($/kg) | Total Cost ($/kg) | ROI (1 year) |
|---|---|---|---|---|
