Microfiber is a fiber with less than 1 denier per filament. (Denier is a measure of linear density and is commonly used to describe the size of a fiber or filament. Nine thousand meters of a 1-denier fiber weigh one gram.) Fibers are combined to create 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 or other polymers.

Production of ultra-fine fibers (less than 0.7 denier) dates back to the late 1950s, using melt-blown spinning and flash spinning techniques. However, only fine staples of random length could be manufactured and very few applications could be found. Experiments to produce ultra-fine fibers of a continuous filament type were made subsequently, the most promising of which were run in Japan during the 1960s by Dr. Miyoshi Okamoto. Okamoto’s discoveries, together with those of Dr. Toyohiko Hikota, resulted in many industrial applications. Among these was Ultrasuede (also known as Alcantara), one of the first successful synthetic microfibers, which found its way onto the market in the 1970s. Microfiber use in the textile industry then expanded. Microfibers were first publicized in the early 1990s in Sweden, and saw success as a product in Europe over the course of the decade. In 2007, Rubbermaid began a line of microfiber products for American markets, the first major company to do so.
