Microdenier or microfiber (these terms are often used interchangeably) materials have very unique wiper properties, especially considering the material is a synthetic-based product. Microdenier materials have been used in consumer applications for many years but are just starting to receive attention in controlled environments. The favorable attribute of microdenier materials is the ability to clean a smooth surface such as glass or stainless steel without having to use a solution such as isopropyl alcohol (IPA) or deionized water (DIW). A practical demonstration is dry wiping a pair of glasses or a smart phone display—fingerprints and skin oils are removed without scratching the surface. The very fine filament fibers make the microdenier behave in this fashion, but the very small size of fibers also weakens the fibers making the fabric more susceptible to abrasive surfaces and broken filaments. The broken filaments may also release many more particles and fibers into the work environment.
