Microfiber or microfibre is synthetic fiber finer than one denier or decitex /thread. This is smaller than the diameter of a strand of silk, which is itself about 1/5 the diameter of a human hair.The most common types of microfibers are made from polyesters, polyamides (e.g., nylon, Kevlar, Nomex, trogamide), or a conjugation of polyester, polyamide, and polypropylene (Prolen).Microfiber is used to make mats, knits, and weaves for apparel, upholstery, industrial filters, and cleaning products.icrofiber is used to make many accessories that traditionally have been made from leather: wallets, handbags, backpacks, shoes, cell phone cases, and coin purses. Microfiber fabric is lightweight, durable, and somewhat water repellent, so it makes a good substitute.
Multimode optical fibers, which have a core diameter of 50 micrometers and a cladding diameter of 125 micrometers, can carry hundreds of separate light wave signals over shorter distances. This type of fiber is used in urban systems where many signals must be carried to central switching stations for distribution.n a single-mode fiber, the core is smaller, typically 10 micrometers (a micrometer is one-millionth of a meter) in diameter, and the cladding is 100 micrometers in diameter.
