Microfibers are tiny fibers that have been slit into millions of finer fibers that are no thicker than one hundredth of a human hair. Microfiber consists of two basic fibers, Polyester and polyamide. Each of them has a unique feature. Polyester is a great absorbent, which allows each microfiber towel to hold 5 times it's weight. The molecular composition of the polyamides make it highly lipophilic. This means oily substances easily adhere to the microfiber surfaces.The microfiber fabric contains hundreds of thousands of microscopic threads per square inch that attract grease, dirt and grime. Because of their high static ability microfibers are able to penetrate into microscopic pores of any surface.
