Monofilament

A monofilament is a single, continuous strand made of a polymeric or metallic material. Unlike multifilaments, which consist of many individual fibers, a monofilament is composed of only one strand and therefore has a homogeneous, smooth surface and a defined geometry. Monofilaments are produced by melt spinning: a polymer is melted and extruded through fine nozzles, then cooled and calibrated to the desired thickness. The thickness of the monofilament determines its tensile strength and bending properties. In filtration technology, GKD uses both metal monofilaments (such as stainless steel wires) and synthetic monofilaments made of polyamide, polyester, or polypropylene. Monofilament fabrics are characterized by precise and reproducible mesh sizes, creating defined pore channels. The result is high particle separation accuracy and low pressure drop combined with good cleanability. In food processing, paper manufacturing, and environmental protection, monofilament-based sieve belts are widely used. Their smooth surface reduces adhesion and simplifies cake release. At the same time, by varying filament diameter and weave type, mechanical strength, elasticity, and permeability can be specifically adjusted.
