Expert know-how for the entire production line
Voith supplies reliable products and services for the complete nonwovens production.
Use of nonwovens
Nonwovens are all around us. As the name suggests, the special feature of nonwovens is that unlike textiles they are not woven. Nonwovens are fiber structures that have been joined and bonded with one another using various methods. Due to their individual configuration and great adaptability, they can be found in all areas, from clothing shops and operating theaters, to vehicles, homes or on the roads, where they are largely invisible.
Expert in the nonwovens market
Thanks to our longstanding experience as a systems provider in various industrial sectors, we develop highly innovative solutions for manufacturing textiles and nonwovens that offer economic and ecological benefits.
Voith and Trützschler introduce new Safety Standard for Wet-laid Spunlaced Nonwovens Machines
Our product portfolio for your nonwovens production
The HydroFormer concept builds on Voith’s long experience in the paper and pulp industry. With HydroFormer technology the suspension is highly diluted, so nonwovens can be produced entirely from cellulose, a renewable and cost-effective raw material.
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.
In collaboration with Trützschler Nonwovens, Voith offers solutions for manufacturing wet-laid and hydro-entangled nonwovens. The technologies of both companies are applied in a jointly developed production process known as wet-laid spunlacing.
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.
In October 2013, Voith and Trützschler Nonwovens achieved an important milestone: a nonwoven wipe from their jointly developed wet-laid spunlacing production process successfully passed the tests of the official INDA and EDANA test guidelines and is therefore certified as being “flushable”. Trützschler Nonwovens and Voith have succeeded in producing wet-laid spunlaced (hydro-entangled) nonwovens with high strength when wet.
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.

Continuous fabric performance and optimal productivity are significantly improved with CleanLine traversing cleaning systems. CleanLine is a comprehensive range of fabric cleaners that meets the challenging demands and conditions across the nonwoven industry
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.
Your advantages with CleanLine
- Continuous or shock cleaning systems or a combination of both methods
- Water jets are next to each other for concentrated cleaning
- More of the contaminants are directly contacted and removed by more directions of water jets
- Waste from cleaning and residual cleaning water can be removed by vacuum, catcher tray, the selection of air-knife, with the option of a heated air zone at a range of temperatures for critical applications
- Service and support package to ensure the highest availability and reliability of the cleaning system
