From the Sector

The first installations of the Trützschler Card TC 30i and the Trützschler Integrated Draw Frame IDF 3 are now complete – and the first customers have finished rigorous testing in direct spinning applications.

The Italian company Marchi & Fildi, headquartered in Biella, was one of the first to test the new IDF 3. The company specializes in producing pure and blended yarns made from natural or man-made fibers for flat knitting, circular knitting and weaving. Its products are used for fashion, furnishings and technical applications worldwide. It also places a strong focus on reducing its environmental impact.

Marchi & Fildi’s first trials were carried out with different fiber blends. This included a blend of 70 % soft waste cotton and 30 % polyester as the raw material for rotor direct spinning, with a yarn count in a range of Ne 8 to Ne 12 and Ne 30.
Later tests involved fiber blends of 50 % PET and 50 % recycled cotton from hard textile waste for rotor direct spinning with a yarn count of Ne 30. Experts at Marchi & Fildi stated that this material blend is typically very challenging. Processing secondary fibers made from hard textile waste requires very high competence in yarn production, which Marchi & Fildi impressively demonstrates. It also requires advanced technologies. This is due to technological challenges such as significantly lower fiber length. Trützschler’s IDF technology has a special drafting zone geometry that ensures reliable fiber guidance and controls floating fibers. It generates lower drafts than a conventional draw frame passage and avoids the risk of false drafts and count variations.

Decades of experience with the IDF technology have demonstrated that the higher the short fiber content, the better the result with IDF compared to conventional two draw frame passages. In combination with the TC 30Ri, a variant of TC 30i that has been specifically equipped and configured for processing recycled fibers, the IDF 3 delivers maximum possible quality for the production of sustainable yarns.

Overall, the company’s results showed a 75 % increase in productivity over the previous card model and a 14 % reduction in energy consumption at higher production rates. Combining the TC 30Ri and IDF 3 also enabled Marchi & Fildi to skip the drawing stage from its process, which boosts quality while saving resources and cutting costs.

Spinnova has entered into a yarn development cooperation agreement with the Portuguese company Tearfil, where Tearfil will operate Spinnova’s R&D yarn-spinning line. The yarn-spinning line is intended for product development and will be located in Guimarães, Portugal at Tearfil's facilities.  

The rationale behind the yarn-spinning line is for research and development into using Spinnova's fibre in commercial scale yarn production and to streamline development work with industry partners.   
Spinnova has decided to locate the line in Guimarães in Portugal, at Tearfil’s facilities. Spinnova will benefit from the industry know-how of a strong partner and from the proximity of one of Europe’s most significant textile industry hubs in Portugal. This will improve Spinnova’s access to global textile markets.   

Spinnova’s yarn-spinning line will be installed at Tearfil's premises. The technology delivery and installations are expected to take place in the fall of 2023, and the spinning line is intended to be operational by the end of the year. Tearfil is responsible for the yarn-spinning line's operations, and Spinnova will use a part of the line capacity for its product development.  

In 2021, Spinnova announced that it would establish an R&D yarn-spinning line in Jyväskylä, Finland. The decision to change the location was made during the feasibility planning and discussions with potential partners. This change in location and operational model will slightly decrease the capital expenditure and will lead to lower operational expenses.  

The technology supplier for Spinnova's new spinning mill line is the Swiss-based company Rieter. Rieter is a leading supplier of systems for manufacturing yarn from staple fibers in spinning mills. The company develops and manufactures machinery, systems and components used to convert natural and man-made fibers and their blends into yarns in the most cost-efficient manner.

Trützschler Nonwovens & Man-Made Fibers GmbH started a cooperation with the Italian textile machinery manufacturer Texnology S.r.l. in the field of needle-punching technology. With immediate effect, the companies will offer complete production lines for needle-punched nonwovens under the name of T-SUPREMA.

Web bonding with steel needles represent the largest production process in the drylaid nonwovens segment. The areas of application are predominantly of a technical nature, with the largest applications being durable geotextiles, automotive textiles and filter media. The high adaptability of the needling and finishing processes as well as the broad material base result in a large number of different end products. Needle-punching is suitable for a wide range of man-made and natural fibers including mineral and high-performance fibers.  

Trützschler Nonwovens contributes its many years of experience in fiber preparation and web forming to the cooperation. Texnology is mainly responsible for the needle-punching process. Joint projects can thus build on a broad application expertise.

A first joint project has already been successfully completed, implemented and put into operation.

At this year’s Techtextil in Frankfurt/Main (June 21st to June 24th) Trützschler Nonwovens, Trützschler Card Clothing and Trützschler Man-Made Fibers present various new and proven solutions for the nonwoven, card clothing and man-made fiber sectors. Join us at booth D80 in hall 12.0!

Trützschler Nonwovens invites to talk sustainable fibers such as hemp or linen and out-of-the-box fibers such as nettle and pineapple fibers. Our solutions for manufacturing innovative nonwoven products include machinery and complete production lines for paper grade pulp, re-generated cellulose fibers, cotton and various other natural fibers.

What happens when sustainable meets digital? Trützschler Nonwovens and software partner Proptium introduce T-ONE, our new digital working environment for both fiber- and polymer-based nonwoven producers. T-ONE supports routine tasks such as quality control and recipe management but also enables systematic line monitoring and data collection for T-ONE’s line optimizations.

Trützschler Man-Made Fibers introduces the OPTIMA-based, versatile TEC-O40 and TEC-O80 systems for extruding and spinning industrial yarns (IDY). The modular OPTIMA platform is highly flexible and adaptable to manufacturing a broad spectrum of (semi-)industrial yarns from polyamide, polypropylene or polyester.
