The MicroSauber fiber consists of two polymers (polyamide and polyester). The individual fibers are splitted 11 times. This splitting and the specially developed high-technology finishing process lead to a multiple enlargement surface and thus an extraordinarily high cleaning and suction power.

Wet cleaning with the MicroSauber fiber works by the principle of capillary suction. This breaks the water tension, which would otherwise require the use of cleaning chemicals. The special manufacturing process increases the surface of the fiber by up to 60 % which allows the fiber to absorb 4 – 5 times more water than its own weight.
