Coventry Poly Double-Onyx ESD Wipes

Poly Double-Onyx™ ESD Wipes are made from 2nd generation black no-run monofilament polyester knit, providing excellent strength, absorbency and chemical compatibility. These wipers are perfect for general cleanroom and equipment maintenance, or any critical applications where lint is not tolerated. The black color makes them uniquely valuable as inspection wipes for light colored soils and dust. The conductive carbon filaments are knitted into both sides of the wipes and twice as densely packed as other ESD wipes, for maximum continuity to ground in the 107-109 range.

What type of wipe is best for cleanrooms?

Cleanroom wipes used for critical applications are almost always knitted synthetic fibers. Knitted polyester fabric, like used for Coventry Poly-Wipes (part #6209), is the most popular wipe material for cleanrooms. Knitted polyester is made clean, contaminants can easily be removed from knitted polyester in a cleanroom laundry, and polyester is relatively inexpensive. Non-woven wipes do not offer the advantage of ease in cleaning as their composition causes them to disintegrate in a cleanroom washing machine or cleanroom drier.

Using Black Polyester Cleanroom Wipes: Is It Really Clean?

Since most wipes are white (a sign of cleanliness perhaps) black or darkly color soils are easily seen. However, many contaminants are not dark colored. Instead they are white or light colored. Since they are the same color as the wipe, visually inspecting the used wipe is not completely useful. Thi...
