Drawing
Reducing the cross section of wire by pulling it through a die. |
|
DTW (See
Micronic Filter Cloth )
Abbreviation for "Dutch Twilled Weave". |
|
Ductility
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 (See
Micronic Filter Cloth ) 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". |
