Microfiber is a fiber with less than 1 denier per filament. The Denier is a measure of linear density and is often used to describe the size of a fiber or a filament (9000 meters of a one-denier fiber weighs only one gram). Fibers are combined to form yarns. Yarns are knitted or woven in a variety of constructions. While many microfibers are made of polyester, they can also be composed of polyamide (nylon) or other polymers.

Microfiber products used for consumer cleaning are generally constructed from split conjugated fibers of polyester and polyamide. When a high-quality microfiber is combined with the right knitting/weaving process, it creates an extremely effective cleaning material. This material can hold up to seven times its weight in water.

Microfibers are also used for special cleaning applications, because of their exceptional ability to absorb oils.

This revolutionary fabric is exceptionally soft yet amazingly functional. Used most commonly for cleaning purposes, microfiber is highly absorbent, accumulating liquids, dust, and debris unlike any other synthetic or natural materials available. This magnetic property makes it a popular choice for dusting as it reduces the number of surface and airborne allergens.
