Filter Cloth Yarn Design

Monofilament The surface of the fiber is glabrous, easy for separate Multifilament Combined by many filaments, highest strength, easy for separate Stapel Fiber Combined by many staple and not very easy for separate

Multifilament or continuous filament yarns are produced by continuous extrusion of synthetic resins. The filament bunches, which have a smooth surface are twisted together to form the yarn using a S or Z turn. Increased twisting will reduce blinding (particle retention within the yarn structure) while also decreasing collection efficiency. Multifilament yarns have high tensile strength and average particle collection efficiency. Filter cake release is average.

Monofilament yarns are single heavier extrusions. These extrusions are smooth, have high tensile strength and in some cases are modified with fillers. Monofilament yarn has excellent cake release properties and resistance to blinding. Monofilament yearns have low particle collection efficiency.

Staple (Spun) yarns are continuously extruded synthetic filaments chopped into short lengths. These short fibers are combed and twisted using a cotton or woolen manufacturing system (woolen yarn has a higher bulk). These staple (of spun) fibers have low tensile strength and a large surface area. Particle retention is excellent and cake release poor.

Weaves

Plain Weave Joint point is close, fabrics has high strength Twill weave Joint point is not very close, easy for make the fabrics more dencisity Satin Weave Few joint point. easy for making the surface of the fabric more glabrous

plain

Is one of the most simple weave patterns. The warp and filling threads cross alternately.
plain­woven fabrics are generally the least pliable, but they are the most stable.

Characteristics

High particle retention and low resistance to blinding with average cake release properties.

Twill

Is a weave characterized by a diagonal rib, or twill line. Each warp floats over at least two or more consecutive fill yarns, enabling a greater number of yarns per unit area than a plain weave, while not losing a great deal of fabric stability.

Characteristics

Average resistance to blinding, average cake release, good mechanical strength.

Satin

The face of the fabric consists almost completely of warp produced in the repeat of the weave. This is the most flexible of weave patterns and conforms very easily around most contoured surfaces. Satin weaves are usually four, five, eight, ro twelve harness.

Characteristics

Excellent cake release, average retention, excellent resistance to blinding.
