And, unlike cotton, which is formed of short strands that always come off while washing and attach to the surface after an electrostatic change, the fabric itself is like a net of wires with no holes. Strands in a standard microfiber cloth never fall off since they span from one end of the fabric to the other and cannot come off when washing! Microfiber fabric is formed from splitted and conjugated polyester and polyamide fibres. These fibres are exceptionally soft and have good dimensional stability. They keep their form extremely nicely.
