Abstract
The subject matter disclosed herein relates generally to fabrics composed of micro-denier fibers wherein said fibers are formed as bicomponent fibrillated fiber. The energy is sufficient for fibrillating as well as entangling (bonding) the fibers. These fabrics can be woven or knitted and made from made from bicomponent islands in the sea fibers and filaments or can be nonwovens and formed by either spunbonding or through the use of bicomponent staple fibers formed into a web by any one of several means and bonded similarly to those used for the spunbonded filament webs.
