Microfiber

from Wikipedia, the free encyclopedia
Microfibre fabric for cleaning sensitive surfaces

Microfiber (also called microfiber in the technical literature ) is a collective term for fibers whose fineness is less than 1 dtex , i.e. H. 10,000 m of such a microfiber weighs a maximum of 1 g. The fineness of microfibers is mainly between 0.3 and 0.8 dtex. In comparison, the fineness of the natural fibers cotton is 1.5 to 2.5 dtex, virgin wool 3 to 6 dtex and silk 1.3 dtex. The fiber diameter is then depending on the density between 3 and 10 µm. Normal human scalp hair is between 50 and 70 µm in diameter. Glass fibers and other mineral fibers are called microfibers if their diameter is less than 3 µm. Finer fibers (less than 0.3 dtex) are usually referred to as super microfibers or ultrafine fibers .

Microfiber fabrics are extraordinarily soft and dimensionally stable. Microfiber clothing usually has a label with a reference to microfiber, e.g. B. "100% polyester microfiber". Microfibers can be made from synthetic or natural materials. Many manufacturers use their own trademarks to describe their synthetic fibers. Some examples:

  • Polyester : Trevira Finesse, Diolen® Soft, Fortrel Microspun, DuPont Micromattique, Primabelle, Shingosen
  • Nylon : Timbrelle®, Supplex Microfiber, Tactel® Micro, Silky Touch
  • Acrylic : microsupreme
  • Cellulose : Lyocell

Because microfibers are so fine, many of them can be packed tightly together. Much more fine fibers are required to make a thread, which results in a larger thread surface area. Microfiber textiles are very resistant to lint .

There are special areas of application:

  • Imitation leather such as Alcantara for the production of coat fabrics, gloves or fabrics for upholstered furniture.
  • Functional outerwear (sports and rainwear) made of polyester or polyamide with properties such as water vapor permeability (sweat evaporates through the fabric pores), quick-drying, windproof, water-repellent together with a soft grip.
  • High-performance cleaning wipes that require little or no cleaning agent when in use. For details, see microfiber cloth .
  • Silky fabrics for articles of outer clothing or bed linen.
