Twill:
Wire Cloth in which each warp wire and each shute wire passes successively over and under the two adjacent wires -- in both the warp and shute directions. This over and under movement is shifted one wire with each pass of the shuttle. This pattern permits the weaving of heavier wires in varying meshes.

PRE-CRIMP WEAVES

Pre-Crimp:
Typically found in coarser wire cloth or space cloth specifications. Here, the wires are crimped prior to weaving. The pre-crimp action enables both the warp and shute wires to nest securely with each other restricting their random movement and ensuring an accurate and consistent opening size. This weaving technique adds strength and rigidity to the wire cloth. 
 
Lock Crimp: 
A refinement of the pre-crimp technique. The crimping of the warp and shute wires is done in such a manner to actually 'lock' the wires together at their point of intersection, offering further assurance of no wire movement.  

Inter-Crimp or Multiple Crimp: 
Another enhancement of the basic pre-crimp weave. Both the warp and shute wires are crimped with extra crimps or corrugations between the points of intersection. This technique is usually required when weaving large openings with fine wires. Inter-crimping assures the proper locking of the warp and shute wires and adds rigidity and accuracy.

DOUBLE CRIMP WEAVE

Plain Weave or Double Crimp: 
This is the most type of wire cloth. Here, the wires are not crimped before weaving. The corrugation or depression that is crimped into both the warp and shute wires is a result of the having a plain weave pattern calls for each shute wire to pass over and under successive rows of warp wires and vice versa, like interlacing fingers.  

FILTER CLOTH

Plain Dutch Weave: 
Similar interlacing as in Plain Weave, except the warp wires are larger diameter than the shute wires. The lighter shute wires are driven up close thus forming a de nse filtering medium. This weave displays a tapered or wedge-shaped opening.

Twill Dutch: 
This filter cloth specification technically combines the Twill Weave and Dutch Weave described above. The larger diameter warp wires successively pass over and under the lighter diameter shute wires. Each pass of the shute wires shifts the over and under movement one wire. The shute wires are driven up close, resulting in a tightly woven filter cloth with tapered or wedge shaped openings.

Twill Dutch Double:
Very similar to Twill Dutch Weave, but by proper selection of the wire sizes, the shute wires actually overlap each other when driven up tight into position.. This permits double the wires per inch in the shute direction. This type of wire cloth is usually considered a Micronic Grade filter cloth.

Stranded:
In this type of weave, both the warp and shute wires are made up of separate wires, rather than a single wire. This weave is woven in the twill pattern, producing an exceptionally strong and tight mesh.
