Mechanical bonding of technical webs
The preferred manufacturing process for durable technical nonwovens is needle-punching using barbed steel needles. In cooperation with our technology partner, Texnology S.r.l., and other collaborators, Trützschler Nonwovens delivers complete production lines for felts and needle-punched nonwovens under the brand name T-SUPREMA.
A vast range of requirements
Different applications require varying mechanical properties. For instance:
- In road and water construction, tensile strength of the nonwoven plays a crucial role.
- For air or hot gas filtration, surface uniformity and pore characteristics are essential.
- In the automotive industry, lightweight materials are increasingly valued.
Our technology partner Texnology srl
Texnology, an Italian company, provides innovative needle-punching and web-forming machines tailored to the specific needs of manufacturers of needle-punched nonwovens. Their focus on innovation and reliability ensures top-notch technology, comprehensive customer service, and global technical support. The company’s expertise in producing high-quality nonwovens informs many design decisions.
Needlelooms by Texnology srl
Needlelooms play a central role in the production of high-quality needle-punched nonwovens. They bond the carded and cross-laid web, ensuring that desired mechanical properties such as strength, thickness, and uniformity are achieved.
Texnology, an Italian company, supplies various needle machines for the T-SUPREMA production lines. Depending on customer requirements, single-board or double-board machines are used for needle-punching from below, above, or both sides.Texnology’s machine design incorporates proprietary patents to ensure consistently high nonwoven quality, minimal wear, and thus, high availability of the needle machines.
Other machinery by Texnology srl
Additionally, depending on the end application, our partner also contributes crosslappers, web-forming units, and/or felt drafters.
Different types of crosslappers combine excellent web laying quality and high productivity with low energy consumption. The Stirovelo unit positioned before the crosslapper separates it from the roller card and corrects fluctuations in web weight using scanner data. This system enables automatic profiling without operator intervention.
The optional felt section serves to optimize fiber orientation and the MD/CD ratio of the nonwoven after pre-needling, enhancing throughput or achieving specific performance goals.
Applications of needle-punched nonwovens
- Geotextiles for protection, separation, or filtration.
- Filter media for air, hot gas, or liquid filtration.
- Visible and non-visible automotive textiles (e.g., trunk linings or insulation).
- Carpets and carpet backings.
- Substrate carriers for smooth artificial leather.
- Technical felts.
- Acoustic panels.
- Insoles for shoes.
- Substitutes for foamed structural elements in furniture.
- Countless other applications, including tennis ball felts
