Microfiber

Microfiber is fiber with strands less than one denier. Microfiber is a blend of polyester and polyamide. Fabrics made with microfibers are exceptionally soft and hold their shape well. When high quality microfiber is combined with the right knitting process, it creates an extremely effective cleaning material. This material can hold up to seven times its weight in water. They are also used for some cleaning applications, because of their exceptional ability to absorb oils.

Material of Microfiber

Microfiber is constructed in a blend of 80/20 ratio of polyester/polyamideams. They are made from a warp knitted thread, composed of wedge-shaped polyester filaments with a core of nylon. The fiber's wedge shaped filaments follow surfaces, lift up dirt, and then trap the particles inside the fibers. The capillary effect between the filaments and nylon core creates a high absorbency, which in turn enables this cloth to clean and polish at the same time.
To clean a microfiber cloth, wash with warm soapy water and rinse well. The warm water opens up the fibers, allowing them to release the locked in dirt. Placing the cloths in a washing machine and then drying them in a dryer on low heat is also effective. No fabric softeners of any kind should be used as the chemicals clog up the microfibers, making them less effective. Bleach should also be avoided as it corrodes the fibers over time, making them less effective. Ironing is also potentially damaging.

Functional Uses of Microfiber

Microfiber performance apparel has become a very popular alternative to cotton apparel for athletic wear, such as cycling jerseys, because the microfiber material wicks moisture away from the body, keeping the athlete cool and dry.
Microfiber materials, such as PrimaLoft are also used for thermal insulation as a replacement for down feather insulation in sleeping bags and outdoor equipment, due to its better retention of heat when damp or wet.
