Multifilament

Multifilament yarns consist of numerous fine individual filaments that are combined either in parallel or twisted together. Unlike monofilaments, a multifilament is significantly more flexible and supple because the individual fibers are thinner and support each other. Multifilament fabrics have a larger surface area per cross-section, resulting in higher wettability, good flexibility, and a pleasant texture. In filtration, multifilaments are primarily used in textile belts for paper machines, drying screens, or thickening processes where high mechanical strength and good dewatering are required. GKD combines multifilament support belts with monofilament fine layers to produce robust, durable, and easy-to-clean filter belts. The fine individual fibers can be chemically and thermally adapted depending on the material – for example, polyamide, polyester, polypropylene, or aramid. It should be noted that multifilaments can felt more easily or have protruding fibers; therefore, they are less suitable for applications with high surface shear forces.
