  • microfiber refers to a fiber with less than 1 Decitex per filament (as defined in Textile Terms and Definitions, 11th Edition, published by The Textile Institute). Decitex is a measure of linear density and is commonly used to describe the size of a fiber or filament. Ten thousand meters of a 1-decitex fiber weighs one gram. Some commercial producers use a value of less than 1.3 Decitex to define microfibers. Fibers are combined to create yarns which are knitted or woven in a variety of constructions. While many microfibers are made of polyester (PET), they can also be composed of, but not restricted to, polyamide (PA), polyolefins (PO), polypropylene (PP), or polyethylene (PE), as well as almost any extrudable polymer.
  • PET polyester
  • PA polyamide

  • microdenier refers to a filament fiber that has approximately 1 filament per denier or less (i.e. fibers with denier per filament (dpf) of one or less than one).
  • dpf denier per filament
  • An example would be a 150 denier polyester fiber that was made from 150 individual filaments. Generally, this applies to polyester and polyaramide filament fibers.
  • polypropylene the use of a microdenier configuration is not generally popular due to difficulties in production and then texturization.
  • microdenier polypropylene as the yarn, a similar effect can be obtained by using yarns with 2 denier per filament as well.
  • the scope of this disclosure includes the use of yarns comprising microfibers and/or UMF in conjunction with yarn comprising polymeric fibers.
  • UMF Ultra Microfibers
  • a commonly used fiber would be a 160 denier fiber which is made up of 72 filaments which have each been divided into 16 sub-filaments.
  • UMF Ultra MicroFibers
  • the split can be in any number between 10 and 50 sub filaments to a single filament of a normal or micro denier filament, but normally a skilled artisan would expect to see no less than 10 filaments per denier in such a product.
  • These yarns are typically not used in the apparel industry for a variety of reasons, and are generally made from more than one polymer such as nylon (PA) and polyester (PET) or polypropylene (PP), or a combination of different polymers and are used in mops and towels where high levels of moisture gathering is an advantage.
  • PA nylon
  • PET polyester
  • PP polypropylene
  • UMF yarns have not been used in apparel because they take in the water between the filaments and retain moisture in the spaces between the split filaments, more than normal yarns do, unless this water absorption and retention effect can be controlled, as described in this disclosure.
  • Microfibers are commonly used in the textile industry but the use of UMF are far less prevalent in apparel. These fibers can take many forms such as a very fine filament made from one polymer, side by side configurations of one or more polymers, or concentric configurations of one or more polymers. In addition, they can be made a wide variety of polymers.
  • Useful polymers for making these fibers in a yarn include: PET (polyester); PEN polyester; Nylon 6,6; PCT polyester; Polypropylene (PP); PBT polyester; Nylon 6; co-polyamides; Polylactic acid (PLA); polystyrene; Acetal; polyurethane (PU); Soluble co polyester; HDPE, LLDPE.
  • microfibers and UMF Methods of producing microfibers and UMF are well known to the skilled artisan.
  • a variety of almost any combination of extruded polymers can be used to obtain the effect.
  • Common names to describe these production methods are "lslands-ln- The-Sea” or “Splittable Pie” systems, which ultimately produces the desired effect in the fibers.
  • a multitude of individual small fibers of one polymer are spun inside of a matrix, or "sea,” of another fiber.
  • the “islands” typically compose approximately 80% of the fiber and the "sea” is
  • microdenier filaments are developed when the sea polymer is dissolved after the yarn or fabric has been woven or knit.
  • the "Splittable Pies" production method of making microfibers and UMF includes the use of a 2 to 4 dpf bicomponent pie yarn, which is again spun and processed with standard techniques. Once in fabric form, a mild caustic solution is applied to the fabric causing the individual fibers to split apart from the main fiber. Thus, for example, if a 32- segment pie of nylon/polyester is used, the final dpf of the fibers is about 0.1.
  • Brushing and other types of finishing techniques can be used to finish the production of the regions of apparel of this disclosure that contain the microfibers.
  • This disclosure provides an article of apparel comprising one or more regions incorporating microfibers or UMF. These regions of the apparel act in contact with human skin to keep the apparel correctly seated against the skin, thereby keeping the apparel correctly positioned on the wearer, particularly while the wearer is engaged in an athletic activity.
