Nonwovens

Reliable solutions for nonwovens production

A wide range of processable fibers (cellulose, synthetic and inorganic fibers) up to 40 mm long can be used in various applications. This technology is already being used to produce teabags, coffee filters, nonwoven wallpapers, cigarette filter papers, overlay papers, fiberglass mats and hydro-entangled nonwovens. Multi-ply nonwovens can be produced directly, without downstream processing, from several layers with different material combinations.

The productivity of these systems eclipses that of conventional systems. To provide investment security, customer tests with the HydroFormer technology and optimized Voith fabrics can be carried out at our Düren pilot facility.

The job of the Voith HydroFormer is to form the wet-laid nonwovens. In this “wet-laid process”, which is similar to the manufacturing process for paper, a suspension of fibers and water is passed over a wire on which a homogeneous fiber mat forms. The downstream hydro-entanglement (spunlacing) process using the Trützschler Nonwovens AquaJet system produces bonded nonwovens that can also be textured or perforated if required. Because AquaJet bonds the nonwovens exclusively through the momentum of the water jets there is no need for binding agents or bi-component fibers.

Trützschler was established in 1888 and has a workforce of around 3,000. It is one of the leading manufacturers of textile machines in the world. The family-owned company steeped in tradition specializes in machines, equipment and accessories for the spinning preparation, nonwoven and man-made fiber industries.

Trützschler Nonwovens is a division of Trützschler Nonwovens & Man-Made Fibers and resulted from the amalgamation of the long-established companies Fleissner, Erko and Bastian. The company provides manufacturers from all over the world with solutions for the entire nonwoven process chain from bale opening to fiber blending, web formation, bonding, finishing and winding, and for man-made fiber facilities.

Because the wet-laid spunlacing process does not use any binding agents or bi-component fibers the wipes quickly disintegrate in water and the fiber material is 100% bio-degradable. Another advantage of using large amounts of long-fiber pulp is that this substantially reduces production costs.

Successful testing to EDANA/INDA criteria is impressive testimony to the efficiency of the newly developed wet-laid spunlacing production process.

The customized ventilation and drying concepts optimize nonwoven and textile production by ensuring ideal climatic conditions for the production technology used.

Spunbond is one type of process for producing a nonwoven and air laid is another. Voith has products for both in fabrics and rolls. Furthermore, with high-tech fabrics, roll covers made of various materials and an experienced Mechanical Roll Service, Voith provides solutions for different industrial applications that go beyond the nonwoven and textile production.

With decades of experience in cleaning synthetic and metal fabrics, Voith uses high pressure water jets to remove contamination on the surface, in the structure and at the edges of a fabric. The main nozzle of CleanLine gives a high number of water jets that are close together for concentrated cleaning of the fabric. An air-knife is attached to the cleaning head directly after the water jets to help drying of the fabric.
