Types of Weaves
Plain Weave is the most commonly used and simplest
wire cloth weave. Each warp wire (wire
running-parallel to length of cloth) passes alternately over and under
the wires running traversely through the cloth (fill or shoot wires) at
90 degree angles. It has an extremely wide range of applications.
Dutch Weave is produced by the use of coarse mesh (mesh
wire, woven wire mesh, wire mesh basket) in the warp and a fine mesh
with relatively smaller wire in the fill. This weave results in greater
strength with very fine openings and is primarily used as a filter
cloth. The shape and position of the openings aid particle retention and
increase filter cake formation.
Twilled Weave is produced by passing each
fill wire alternately over and under two warp wires. The pattern is
staggered on successive warp wires, giving the appearance of parallel
diagonal lines. This weave allows the use of proportionately heavier
wires in a particular mesh count (number of openings per lineal inch)
than is possible in plain weave. This cloth has a wide application
capable of supporting greater loads and finer filtrations.
Twilled Dutch Weave is produced by a
combination of the features of the Dutch Weave and the Twilled Weave.
Fill wires are passed alternately over and under two warp wires forming a
fine mesh in one direction and a coarse mesh (mesh wire, woven wire
mesh, wire mesh basket) in the other. This type of weave is capable of
supporting greater loads than the Dutch Weave, with finer openings than
the Twilled Weave. It is used in applications where the filtering of
heavy material is necessary.
cloth (woven wire cloth, stainless steel wire cloth, wire cloth screen,
wire cloth strainer, industrial wire cloth, metal cloth, wire cloth) is
metal wire of various alloys that is woven or welded forming a cloth
like material. Wire cloth can be formed in a variety of opening sizes
and wire diameters. The open area is call mesh count or mesh per linear
inch and is the critical information needed when ordering wire cloth.

Measuring Wire Cloth
|A:||Space Cloth identifies the open area between the parallel wires. |
|B:||Mesh Count identified as the number of openings per linear inch.|
Mesh count can be shown as either a whole number, fraction, or as two numbers unless the material is a specialty cloth called space cloth - each item is described below:
- Whole Number or Fraction
Mesh Count is identified as the distance from center to center of the parallel wires horizontally and vertically.
- Space Cloth
This material is measured by the actual open space between parallel wires, known as clear opening, space size, or open area.
- Two Numbers (Example: 2 x 2 )
Mesh Count is identified by the number of actual openings per linear inch horizontally and vertically.
Mesh = 1 / (wire diameter + opening)
Open area = (opening x mesh)² x 100
= (1 - (wire diameter x mesh)² x 100mesh
= (1 - (wire diameter x mesh))² x 100
Opening = (1 / # wires per inch) - (wire diameter)

How to Measure Wire Cloth
To measure wire cloth (woven wire cloth, stainless steel wire cloth, wire cloth screen, wire cloth strainer, industrial wire cloth, metal cloth, wire cloth) properly, the mesh count should be taken in both directions. On coarse meshes (mesh wire, woven wire mesh, wire mesh basket), this can be accomplished by counting the number of openings per linear inch measuring from wire center to wire center. After taking the first count, a second count should be taken at a 90 degree angle to the original measurement. The mesh count of the cloth shown is 10x10.
A mesh counter is used to measure finer meshes of wire cloth (woven wire cloth, stainless steel wire cloth, wire cloth screen, wire cloth strainer, industrial wire cloth, metal cloth, wire cloth) accurately. The fine mesh count is taken the same way the coarse mesh is computed by counting the number of openings per linear inch in one direction and taking another count at right angles to the original measurement.
Wire diameter is always checked with a micrometer. Diameters of wires in both directions should be checked.

Wire Cloth Uses
Although there are many uses for wire cloth, it is rarely seen. Industrial wire cloth is considered a component for equipment that has a need for filtering, separating, straining, sizing, diffusing, providing structure, etc.
