GRAIN MESH

The prototypical prototype. A plastic mesh is extruded, oriented, expanded or tubular. Plastic mesh can be made from polypropylene, polyethylene, nylon, PVC or PTFE.  A metal mesh can be woven, welded, expanded, photo-chemically etched or electroformed (screen filter) from steel or other metals.  In clothing, a mesh is often defined as a loosely woven fabric with many closely-spaced holes, frequently used for modern sports jerseys and other apparel. Meshes are often used to screen out unwanted things, such as insects. A prototype is an original type, form, or instance of something serving as a typical example, basis, or standard for other things of the same category. The word derives from the Greek πρωτότυπον (prototypon), "primitive form," neutral of πρωτότυπος (prototypos), "original, primitive," from πρῶτος (protos), "first" and τύπος (typos), "impression."
