Cleanroom wipes used for critical applications are almost always knitted synthetic fibers. Knitted polyester fabric, like used for Techclean Purwipe (part #2355-100), 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. Techclean Anti-Static Wipes (#2362-150) are also woven polyester, but include stripes of DuPont’s NEGA-STAT carbon yarn. This prevents static generation, which is especially important when dry wiping. Anti-Static Wipes are packaged in a class 10 cleanroom, so ideal for cleanroom applications. This wipe is widely used on smart phone and pad computer screens in assembly or repair operations. Wiping glass screens with standard polyester will tend to generate static and attract dust.
