Cleanroom Paper Selection Guide
| Classification Basis | Type | Core Material & Technical Characteristics | Typical Form | Key Performance Metrics | Primary Application Fields |
|---|---|---|---|---|---|
| By Primary Fiber Material | 100% Polyester | Fabric formed from pure polyester via meltblown, spunbond, or needle-punch processes. Pure structure, excellent chemical compatibility, low extractables. | Sheets (folded/stacked), Rolls | Surface Resistivity: Can be static-dissipative or insulative Particle Emission: Very Low Liquid Absorbency: Moderate (can be hydrophilically treated) | Highest Cleanliness Demands: Semiconductor wafers, optical lenses, microelectronic components, Class 100 and above cleanrooms. |
| Polyester + Cellulose Blend | Blend of polyester (provides strength) and wood pulp/viscose fibers (provides high absorbency). Cost-effective, fast absorption with high capacity. | Sheets, Rolls, Bulk | Liquid Capacity: Very High Tensile Strength: Moderate Cleanliness: Good | General-Purpose Industrial Wiping: Machining, equipment maintenance, lab benches, large liquid spills, medium-grade clean zones. | |
| 100% Cellulosic Fibers (e.g., Lyocell) | Made from regenerated cellulose fibers (e.g., via solvent spinning). Biodegradable, extremely soft, with superior absorption. | Sheets, Rolls | Absorbency: Excellent Softness: Exceptional Cleanliness: High | Applications Demanding High Cleanliness & Softness: High-end display panels, medical device cleaning, precision instruments, eco-sensitive environments. | |
| By Final Product Form & Use | Sheets/Folded Dry Wipes | The standard form for dry wipes. Pre-folded for one-handed dispensing, sealed in protective packaging. | C-Fold, Z-Fold, Stacked | Size: e.g., 20x20cm Edge Seal: Laser/Ultrasonic (for high grade) | Manual Precision Wiping: Applying solvents, equipment upkeep, laboratories, manual operations on assembly lines. |
| Roll Wipes | Economical bulk format. Custom length can be torn off, suitable for large areas or high-frequency use. | Rolls (with/without core) | Width: e.g., 30cm, 45cm Length: 50-100m/roll | Large-Area Cleaning / Automation: Used with dispensers for large panels, workshop maintenance, integration into automated equipment. | |
| Pre-Saturated Wipes | The “ready-to-use” variant, impregnated with a specific solvent (e.g., IPA, DI water) during manufacturing and sealed. | Individually wrapped, Canisters | Solvent Type: IPA, Ethanol, specific cleaners Saturation: Controlled & uniform | Standardized Processes: Where consistent solvent type/concentration is critical, e.g., medical disinfection, specific semiconductor steps, field service repair. |
What Are Dry paper (Sheets)?
Dry wipes are absorbent, disposable sheets of nonwoven fabric, similar in form to a wet wipe but without any pre-added cleaning solution or moisture. They are a versatile “dry canvas” used for a wide range of tasks where controlled application of a liquid or a dry absorbent is needed.
Core Selection Logic
Match Cleanroom Class:
Class 100 & above: Prioritize 100% polyester, laser-sealed wipes.
Class 1K – 100K: Opt for polyester blends or high-quality cellulosic wipes.
General Industrial: Polyester-cellulose blend roll goods offer the best cost efficiency.
Define the Cleaning Task:
Absorbing Large Liquid Volumes: Choose high-loft polyester-cellulose blend material.
Precision Wiping with Solvents: Select low-extractable 100% polyester or Lyocell wipes.
Standardized Disinfection/Cleaning: Use matched pre-saturated wipes.
Consider Cost & Sustainability:
Evaluate cost-per-use (not unit price), balancing performance and waste.
For environmental goals, consider biodegradable cellulose-based materials (e.g., Lyocell).
