The Ultimate Cleanroom Wipe Showdown: Polyester vs. Microfiber
-
Introduction: Why Your Wipe Choice Defines Your QC
-
Briefly state the stakes: particle contamination risk.
-
Introduce the two main contenders: Polyester Knit (the workhorse) and Microfiber (the specialist).
-
H2: Polyester Wipes: The Industry Standard for Critical Cleaning
-
Pros (When to Choose Polyester):
-
Excellent chemical compatibility (ideal for IPA, Acetone).
-
Low NVR (Non-Volatile Residue) and minimal particle shedding (especially sealed-edge).
-
Cost-effective for high-volume, general critical wiping.
-
-
Cons:
-
Lower absorbency compared to microfiber
-
Microfiber Wipes: The Specialized Tool for Ultra-Fine Surfaces
-
Pros (When to Choose Microfiber):
-
Superior absorbency (best for liquids and spills).
-
Outstanding particle and residue removal (mechanical cleaning action).
-
Ideal for sensitive surfaces (optics, LCDs) where scratch-free cleaning is paramount.
-
-
Cons:
-
Higher cost per unit.
-
Can have higher particle shedding if not properly processed/laundered.

H2: Critical Comparison Table: Polyester vs. Microfiber (The Data)
| Feature | Polyester Knit (Sealed Edge) | Microfiber (Knit) | Best For |
| Particle Shedding | Very Low | Low to Moderate | IPA Wiping |
| Absorbency Rate | Good (Relatively Low) | Excellent (High Volume Spills) | Liquid Cleanup |
| Chemical Resistance | Excellent (High Solvents) | Moderate (Solvents can degrade structure) | Aggressive Solvents |
| Cost | Medium | High | Budget |
| Primary Use | General critical wiping, solvent application | Delicate surfaces, heavy residue removal |
Sourcing Considerations for Supply Chain Managers
-
The importance of Manufacturer Certification (ISO, IEST).
-
Bulk vs. Small orders: Negotiating better wholesale pricing.
-
Ask your supplier for NVR test reports.
Conclusion: Making the Final Decision
-
Summarize: Use Polyester for chemical wiping; use Microfiber for mechanical/sensitive cleaning.
