Special weave in which both sides of the cloth show a smooth broken twill surface. Offers excellent stability, retention and cake release properties.

Plugging up of a filter fabric resulting reduced flow rates and filtration efficiency.

Ability of a filter cloth to completely discharge the cake from the cloth.

Describes the diameter of the fiber, i.e. the lower the denier the finer.

A filtration fabric with highly conductive fibres, commonly carbon based or steel, incorporated into it so that electrical charges are quickly dispersed.

Single, long continuous strand of a synthetic fibre extruded in a relatively coarse diameter.

Smooth yarn consisting of two or more monofilaments twisted tightly together.

A cloth formed by ‘needling’ fibres until they are sufficiently interlocked and compressed to form a continuous cloth. Filtration Needlefelts are usually ‘needled’ both sides onto a ‘Scrim’ or open fabric which provides a large part of the mechanical strength of the final material.

Modified plain weave where both warp and weft yarns are multiple yarns but not of equal number.

The simplest and most common weave produced by passing the weft thread over and under each successive warp thread. Offers low permeability and excellent particle retention but is susceptible to blinding.
