TWILL WEAVE PRE-CRIMP WEAVES DOUBLE CRIMP WEAVE
Twill: In the warp and shute directions, each warp wire and each shute wire pass successively over one and under two adjacent wires in the wire cloth. This movement is shifted with each pass of the shuttle. This pattern permits the weaving of heavier wires with varying meshes.
Pre-Crimp: Typically found in coarser wire cloth or space cloth specifications. The wires are crimped priorly before weaving. The pre-crimp action enables both the warp and shute wires to nest securely with each other in restricting their random movement and ensuring an accurate and consistent opening size. This weaving technique increases strength and rigidity to the wire cloth. Lock Crimp: The refinement of the pre-crimp technique. The crimping of the warp and shute wires is made in lock crimp to actually 'lock' the wires together at their point of intersection and offer 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.
Plain Weave or Double Crimp: This is the most common type of wire cloth. The wires are not crimped before weaving. The corrugation or depression that is crimped into both the warp and shute wires is the result of the plain weave pattern that requring each shute wire to pass over and under successive rows of warp wires and vice versa, just like interlacing fingers.
FILTER CLOTH Plain Dutch Weave: It is similar interlacing as in Plain Weave, but the diameters of the warp wires are larger than the shute wires. The lighter shute wires are driven up to be closed to form a dense filtering medium. This weave style displays a tapered or wedge-shaped opening.
Twill Dutch: This filter cloth specification technically combines the Twill Weave and Dutch Weave as we described in the above paragraphes. The warp wires with larger diameter 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: It is greatly similar to the Twill Dutch Weave. But the shute wires actually overlap each other when driven up tight into position if by proper selection of the wire sizes. This permits the wires to double one inch in the shute direction. This type of wire cloth is usually considered as a Micronic Grade for 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 to produce an exceptionally strong and tight mesh.
Special specifications can be produced by the customer's requirements.
