What laser-cut edges are and why they matter
A laser-cut edge is formed by melting the polyester filaments as the wipe is cut, so the cut ends fuse together instead of staying open.
WestonWiper cuts with high-precision CO₂ laser equipment. The high-energy beam does not touch the fabric: it melts the filament ends, and all four edges of each polyester cleanroom wipe are sealed in the same cutting operation. Locking the fiber ends in place is intended to reduce the loose threads and fragments that open, cold-cut edges can release, and the equipment cuts to a precision of up to ±0.05 mm, which keeps wipe dimensions consistent from piece to piece.
Edge condition and particle release also depend on the fabric and process settings, so any quantitative claim should be backed by test data for the exact configuration ordered.

Test Reports
The available report excerpts show PASS results for restricted substances and non-detected (N.D.) results for four phthalates in the tested sample.
| Substance group listed in the report | Reported result |
| Lead, cadmium, mercury, hexavalent chromium, PBBs and PBDEs | PASS |
| DEHP, BBP, DBP and DIBP | PASS |

| Diisobutyl phthalate (DIBP) | N.D. | 50 mg/kg | 1,000 mg/kg |
N.D. means the substance was not detected at the stated method detection limit; it does not mean the concentration is zero. These results apply to the tested sample identified in the report.

Manufacturing process and facility
Clean base fabric in: clean polyester filament base fabric is fed into the line.
Laser cutting: a CO₂ laser cuts each wipe to size with up to ±0.05 mm precision and seals all four edges.
In-line dust removal: cut wipes are cleaned in line to remove loose dust.
Cleanliness inspection: sampling checks cover particles, appearance and dimensions.
Double-layer vacuum packing: wipes are sealed in double-layer clean bags under vacuum.
The workshop is equipped with high-precision CO₂ laser cutting equipment and uses a non-contact melt-sealing process. The high-energy beam instantly melts the polyester filaments and fuses the edge, locking fiber ends in place. This is intended to reduce the loose threads and shedding associated with cold-cut edges, and the cutting precision keeps dimensions consistent for semiconductor, optical and medical users with tight requirements.
FAQ
Q: What are WestonWiper Laser Cut Cleanroom Wipes made of?
A: They are made of 100% polyester filament fabric, cut with a CO₂ laser that melts and seals all four edges.
Q: Which sizes are available?
A: The standard sizes are 4, 6, 9 and 12 inches (about 102, 152, 229 and 305 mm). Other dimensions can be made by agreement; confirm the finished length × width when ordering.
Q: Which fabric weights are available?
A: Fabric weight is customizable from 80 to 250 gsm. State the target gsm and the tolerance you need during quotation.
Q: How many wipes come in a pack and a carton?
A: The standard is 100 wipes per pack and 50 packs per carton, which is 5,000 wipes. Other quantities require separate confirmation.
How is a laser-cut edge different from a cold-cut or ultrasonic edge?
A laser melts the filament ends without touching the fabric, so the edge is fused and sealed. A cold-cut edge is sheared and its fiber ends stay open, while ultrasonic cutting fuses the edge with vibration and tool contact.
Q: Do laser-cut wipes release fewer fibers?
A: Sealing the edge is intended to reduce loose threads compared with open cut edges, but the amount released depends on the fabric and the process. Request particle-release data for the exact configuration you plan to order.
Q: What is the cutting accuracy?
A: WestonWiper's laser cutting equipment cuts to a precision of up to ±0.05 mm. The finished-size tolerance for your order is agreed in the approved specification.
