Produce Meltblown Fabric: Complete Production Process, Cost Structure & Buyer Guide (2026)
Produce Meltblown Fabric: A Procurement-Focused Deep Industry Guide
In today’s filtration-driven global market, understanding how manufacturers Produce Meltblown fabric is critical for buyers, importers, and OEM brands. Meltblown fabric is the core layer in masks, filtration systems, and medical materials. Yet most buyers still evaluate suppliers only based on price—without understanding how production impacts quality and cost.
This is where many sourcing mistakes happen.
This guide is different. Instead of simply explaining the process, we connect how factories Produce Meltblown fabric with real procurement decisions: pricing logic, quality risk, and supplier capability.
If you want to source competitively, you must understand how suppliers Produce Meltblown fabric at a deeper level.
1. What Is Meltblown Fabric?
Before analyzing how to Produce Meltblown fabric, buyers need to understand its structure.
Meltblown fabric is a nonwoven material made from ultra-fine fibers (1–5 microns) created by blowing molten polymer with high-speed hot air.
Key characteristics:
-
Extremely fine fiber diameter
-
High filtration efficiency
-
Low basis weight
-
Electrostatic charge capability
Table 1: Meltblown vs Other Nonwoven Processes
| Process Type | Fiber Size | Bonding Method | Cost Level | Application |
|---|---|---|---|---|
| Meltblown | 1–5 μm | Self-bonding | High | Masks, filters |
| Spunbond | 15–30 μm | Thermal | Low | Bags |
| Spunlace | 10–20 μm | Water jet | Medium | Wipes |
| Needle punched | 20–100 μm | Mechanical | Medium | Automotive |
The unique fiber size is why it’s difficult to Produce Meltblown fabric consistently.
2. Raw Materials Used to Produce Meltblown Fabric
The primary material used to Produce Meltblown fabric is polypropylene (PP) with very specific requirements.
Table 2: Raw Material Specifications
| Parameter | Typical Value |
|---|---|
| Melt Flow Index | 800–1500 g/10min |
| Density | 0.90–0.91 g/cm³ |
| Moisture | <0.05% |
| Additives | Electret masterbatch |
Procurement insight:
Not all PP is suitable. Only high MFI PP can be used to Produce Meltblown fabric effectively.
3. Step-by-Step Process to Produce Meltblown Fabric
Understanding each stage is essential for evaluating suppliers.
Step 1: Polymer Feeding
Polypropylene pellets are loaded into the extruder.
Step 2: Melting
Material is heated to 250–320°C.
Step 3: Extrusion Through Die
Molten polymer passes through micro-nozzles.
Step 4: High-Speed Air Blowing
Hot air stretches fibers into microfibers.
Step 5: Fiber Collection
Fibers are deposited on a collector.
Step 6: Electrostatic Charging
Fabric is charged to enhance filtration.
Step 7: Winding
Fabric is rolled for shipment.
Table 3: Process Parameters
| Stage | Parameter | Range |
|---|---|---|
| Extrusion | Temperature | 250–320°C |
| Air velocity | Speed | 200–400 m/s |
| Die holes | Diameter | 0.2–0.4 mm |
| Collection distance | Gap | 15–30 cm |
Each parameter affects how well factories Produce Meltblown fabric.
4. Machinery Used in Meltblown Production
Equipment precision determines product quality.
Table 4: Key Equipment
| Equipment | Function |
|---|---|
| Extruder | Melt polymer |
| Meltblown die | Form microfibers |
| Air heater | Provide hot air |
| Collector | Form fabric |
| Electret system | Add static charge |
| Winder | Roll fabric |
High-end lines significantly improve consistency when factories Produce Meltblown fabric.
5. Cost Structure of Meltblown Fabric
Meltblown production is more expensive than spunbond.
Table 5: Cost Breakdown
| Component | Percentage |
|---|---|
| Raw material | 50–60% |
| Energy | 20–30% |
| Labor | 5–10% |
| Maintenance | 5–8% |
| Depreciation | 5–10% |
Energy plays a larger role because of hot air requirements when factories Produce Meltblown fabric.
6. Filtration Efficiency and Performance
Performance is the key value driver.
Table 6: Filtration Performance
| Grade | Efficiency (%) | Application |
|---|---|---|
| BFE 95 | ≥95% | Medical masks |
| BFE 99 | ≥99% | Surgical masks |
| HEPA | ≥99.97% | Air filters |
Filtration depends heavily on how manufacturers Produce Meltblown fabric.
7. Production Capacity and Output
Production efficiency varies widely.
Table 7: Line Capacity
| Line Width | Output (kg/day) |
|---|---|
| 1.6 m | 500–800 |
| 2.4 m | 800–1200 |
| 3.2 m | 1200–2000 |
Higher efficiency reduces cost when factories Produce Meltblown fabric.
8. Common Defects and Their Causes
Understanding defects helps buyers avoid bad suppliers.
Table 8: Defect Analysis
| Defect | Cause |
|---|---|
| Low filtration | Poor electret charging |
| Fiber breakage | Incorrect air speed |
| Uneven thickness | Poor die design |
| Weak strength | Improper cooling |
These issues often reveal poor control when factories Produce Meltblown fabric.
9. Procurement Strategy: How Buyers Win
