Synthetic microfibers are made from polyester and nylon (polyamide). When splitting the microfibers, they have greater absorption and dust attraction. What does all this mean? It means that microfiber is a superior cleaning material for both wet and dry applications (wet mops, dust mops, wipes etc.). Microfiber benefits include absorbing 6x its weight, excellent at holding onto dirt and dust, reducing or eliminating chemical usage and depending on the quality, can be laundered several hundred times. But, not all microfiber is created equally. Always review samples before purchasing. For more information visit cleanlink.com and click on Microfiber.
