History of Microfiber Products Microfiber is synthetic fiber finer than one denier or decitex (dtex, is a metric unit)/thread, having a diameter of fewer than ten micrometers. This is smaller than the diameter of a strand of silk (which is approximately one denier), which is itself about 1/5 the diameter of a human hair. The most common types of microfibers are made from polyesters, polyamides (e.g., nylon, Kevlar, Nomex, trogamide), or a conjugation of polyester, polyamide, and polypropylene. Microfiber is used to make mats, knits, and weaves for apparel, upholstery, industrial filters, and cleaning products. The shape, size, and combinations of synthetic fibers are selected for specific characteristics, including softness, toughness, absorption, water repellency, electrostatics, and filtering capabilities. Production of ultra-fine fibers (finer than 0.7 deniers) dates back to the late 1950s, using melt-blown spinning and flash spinning techniques. However, only fine staples of random length could be manufactured and […]
