Current spray designs coat the exposed surface of the top layer of fibers, while fibers in the interior do not get treated. Fibers also move around when transported during processing, leading to exposure of untreated surfaces. An organization seeks novel technologies that can apply a spray coating to the entire surface area of a collection of fibers. New spray systems and designs must treat the underlying surface area of fibers. Spray systems that can be installed in a confined space are not required, but of additional interest. The invention must be compatible with water-based solutions.
