Microfiber in cleaning.

To date, microfiber is the "last word" in cleaning services.  At the heart of the microfibre fabric lie superfine filaments made of polyester and polyamide, which are more resistant to abrasion.Microfibers are able to attach themselves to even the smallest, most microscopic dirt particles—ones that normal cloth fibers (positively giant in comparison) crudely brush past. If forces were visible, you'd be able to see that there are adhesive forces (the forces of attraction) between microfibers and dirt. 

Advantages of microfibre in cleaning:

• When making dry cleaning microfibre cloths keep dust, not allowing it to fly away.
• Each side of the microfiber cloth does not allow the dust to pass to the other side.
• Microfibre cloths perfectly absorb water and are rinsed well from dirt.
• Microfibre cloths are resistant to aggressive chemical agents.
