ABSTRACT:
A method of constructing a clean room utility pouch includes cutting dust-proof fabric in accordance with a pattern. The cut edges of the dust proof fabric are treated to eliminate loose particulates or loose fibers along the cut edges. Piping can be secured over the cut edges instead of treating, or in addition to treating the cut edges, and finished by securing the pieces together to form the utility pouch. In some embodiments, a mesh is secured to the cut edges to form a portion of the utility pouch. Air can then flow into and out of the pouch via a pouch opening and the mesh.
