Drawing Reducing the cross section of wire by pulling it through a die.
DTW Abbreviation for "Dutch Twilled Weave".
The ability of a material to deform plastically without fracturing, being measured by elongation or reduction of area in a tensile test, or by other means.
Duplex Weave This specification is similar to a Plain Dutch Weave except that two warp wires are used, rather than one.
Dutch Weave Wire mesh or filter cloth with warp wires larger than the shute wires. Warp wires remain straight while adjacent shute wires slightly overlap, resulting in a dense, strong material with small irregular, twisting passages that appear triangular in shape when viewing the material diagonally. See - "Hollander Weave"
Dutch weaves have much lower flow rates and much higher particle retention than plain square weaves. - E - electro-galvanized An electrical plating process that results in a thin evenly distributed coating of zinc over all exposed carbon steel wire surfaces. Recommended for 8 mesh and higher mesh counts where hot dip galvanizing is not suitable after weaving.
Elongation In tensile testing, the increase in the gage length, measured after fracture of the specimen within the gage length, usually expressed as a percentage of the original gage length.
end tension screens Edge preparation on a screening surface allowing it to be stretched in the direction of material flow.
end tension wire cloth Typically required for long slotted apertures, wire cloth that is tensioned from one or both ends in the direction of material flow, as opposed to side-to-side tensioning methods.
- F - fanning mill cloth Wire cloth used for sizing and grading many types of beans, peas, seeds and for separation of light weight dry materials.
feather edges Straight wire ends protruding around the perimeter of a screen cloth section which are not crimped, all in the same plane.
ferrous alloys Alloys or metals containing iron.
fill wires Wires running across the width or short way of wire cloth as woven, also referred to as "shute", "shoot", "shot" and "weft" wires.
filter A device utilizing filter media for particle retention for clarification of a liquid or gaseous fluids.
filter cloth Wire or synthetic cloth woven with a greater number of wires in one direction than the other, and utilizing two different wire diameters. Filter cloth is woven in both plain and twill weave patterns. Also referred to as "Dutch Weave".
