“Microfiber” is the term used to describe synthetic fibers that are less than one denier (a unit of measure for the linear mass density of fibers).
Microfiber is used and known for its softness, durability, absorption, wicking abilities, water repellency, electrodynamics, and filtering capabilities. These properties make microfiber cloths perfect for cleaning. Microfiber cloths lift off dirt, grease and dust without the need for cleaning chemicals because they are formulated to penetrate and trap dirt. Microfiber cloths will pull the dirt and grime away from the surface with little or no effort. This happens with a wet microfiber due to surface tension and its unique capillary effects. water and particles are pulled deep into the fibers. With a dry microfiber, a negative electrostatic charge attracts dust and dirt particles; it pulls the particles away from the surface. Traditional cotton cloths would just push them around on the surface you are trying to clean. On a traditional cloth, some sort of soap or cleaner is required because that cleaning agent is what attracts and holds the dirt. But with microfibers, the cloth itself does that. You can just use water and the microfiber cloth for all your cleaning needs. Naturally!
