Knit Polyester

Knit polyester wipes are made with 100% continuous filament knit polyester and are sometimes referred to as woven wipes due to how they are constructed. The construction of these wipes lends themselves to have a low particle release, thus giving you a cleaner wipe. Typically offered in single knit, light weight material or double knit heavy weight material. The double knit polyester is more durable and less likely to snag. Polyester absorbs solvents well, however it absorbs water poorly. Polyester can also be cleanroom laundered in order to reach higher levels of cleanliness.

Cotton

Cotton wipes are another woven wipe option making them very durable and absorbent . They also are the wipe with the highest heat tolerance. Cotton does have its downfalls, this material tends to break down creating lint, making it not suitable for extremely critical applications. With this in mind, cotton wipes are usually the highest in particulate release , generally making them best for cleanrooms with less restrictive air particulate requirements.

Poly-cellulose wipes are a non-woven wipe, they are constructed of a blend of polyester fibers and cellulose fibers. Non-woven wipes are the most common general purpose material used in cleanrooms due to their diversity. These are very popular as they blend the cleanliness of polyester, a moderate particle release, with the absorbent characteristic of cellulose.
