How Are Microfiber Cloths Made?

Fifty percent polyester and fifty percent polyamide (another name for nylon). In other words, you have a mixture of two plastics. The cloth is made by forcing the plastics through a tiny pipe and heating them so they weave together. These fused fibers are then split apart into microfibers 10–20 times smaller. In the best cloths, the fibers are 100 times thinner than a human hair—so each one is only one micrometer (one micron) in diameter or even smaller. (This is still microtechnology, not nanotechnology, because micron-sized fibers are 1000 nanometers wide.)
