The edge of a cleanroom wiper is part of its construction. Cutting separates the fabric into individual wipes; sealing applies heat or another controlled process to the perimeter. The edge should be evaluated with the textile, processing, and measured contamination data.
Cut edges
A cut edge may be created mechanically, thermally, or by laser depending on the product. The method and fabric determine the finished perimeter. Q-Leap QL-3009D-LE uses a laser-cut edge.
Ultrasonic-sealed edges
Ultrasonic sealing uses localized energy to fuse a compatible synthetic structure at the perimeter. Q-Leap QL-5009D-HC is documented with an ultrasonic-sealed edge.
Questions for procurement and validation
- Is the edge method explicitly documented for the exact SKU?
- Does the material respond appropriately to the edge process?
- Are LPC, APC, NVR, or fiber-release data available for the complete finished wiper?
- Does the edge remain suitable after the intended solvent exposure or reuse procedure?
- Is the edge appropriate for the target surface and wiping technique?
Do not convert an edge description into an unsupported cleanliness claim. A sealed edge can be a useful differentiator, but it does not replace SKU-specific test data or process qualification.
