Coventry Cleanroom Chamois

Solvent compatibility is another factor to consider when choosing a wipe. If the wipe is to be used with a solvent in the cleaning application, then the wipe must be selected with the solvent in mind. Solvent retention and absorbency may also be required. The wipe must the able to absorb a given solvent and retain the solvent within the fabric of the wipe for a sufficient amount of time, without premature release of the solvent. Knitted polyester and nylon wipes have the highest compatibility with a wide range of organic solvents and weak acids. Coventry Poly-Wipes and Cleanroom Chamois have good absorbency, excellent durability when cleaning rough surfaces, and low ionic and organic residue contamination. The polyester/cellulose blended Chemtronics Controlwipes and Coventry Econowipes have excellent resistance to solvents and weak acids, good durability when cleaning rough, abrasive surfaces, high particle entrapment and low particle and ionic contamination.  They are an economical choice for general cleaning and spill clean-up.

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.
