Micro fibers are synthetic filaments that are interwoven, 75% polyester and 25% nylon, and put through a special process where each filament is split into 12 sections. During the process the polyester turns into wedge-shaped sections surrounding the filament nylon core. A single strand of micro fiber is approximately 1/10th the diameter of a strand of silk (approximately 0.2 denier). . Microfiber is a superior, chemical free, hypoallergenic textile. Microfiber quicker results and clean more easily than conventional cloths. They can be used many times and can last up to 300 times of machine washes.
