Abstract
A fiber web structure made of randomly oriented synthetic fibers, an apparatus for making the web structure and a method of making the web structure. The web is a dimensionally-disordered, aerodynamically-formed structure in which electrostatic and/or non-electrostatic fibers are arranged to create structured fiber webs. The method uses different size, crimp, length and shapes of fibers, among various characteristics, to create strength and other properties. An apparatus for making the web structure includes a randomizing cylinder that removes fibers from a main cylinder, and condensing cylinders. The fiber webs may be structured in layers and the layers may have fibers and/or additives placed in or between the layers for enhanced performance.
