Microfiber is a synthetic fiber that is extremely fine, with a diameter of less than 10 micrometers (one denier or less), making it much thinner than a human hair or silk fiber
. It is typically made from materials such as polyester, polyamide (nylon), or blends of these fibers
. The fibers are so fine that they provide a large surface area, which enhances their absorbency and ability to attract dirt and grease due to a slight positive electrical charge
. Microfiber is used in a wide range of products including cleaning cloths, apparel, upholstery, industrial filters, and bed sheets
. Its unique properties include softness, durability, water repellence or absorbency (depending on construction), and excellent cleaning ability without scratching surfaces, making it ideal for delicate items like glass and lenses
. Microfiber cloths can remove dirt effectively using van der Waals forces and can even reduce the need for harsh cleaning chemicals due to their efficiency in trapping microbes and viruses
. In summary, microfiber is an ultra-fine synthetic fiber known for its softness, strength, high absorbency, and superior cleaning performance, widely used in textiles and cleaning products
