From the Sector

Am 9. und 10. November fand die Aachen-Dresden-Denkendorf International Textile Conference in Stuttgart statt. Die Deutschen Institute für Textil- und Faserforschung Denkendorf (DITF) organisierten in diesem Jahr eine digitale Veranstaltung, nachdem die Tagung in 2020 coronabedingt abgesagt worden war. 360 Teilnehmerinnen und Teilnehmer aus 25 Ländern und vier Kontinenten nutzten die Gelegenheit, bei einem der wichtigsten europäischen Fachkongresse dabei zu sein. Ministerialdirektor Michael Kleiner überbrachte ein Grußwort der Ministerin für Wirtschaft, Arbeit und Tourismus Baden-Württemberg, Nicole Hoffmeister-Kraut, die das gelungene Programm des textilen Branchentreffs würdigte. Die Konferenz wird jährlich im Wechsel von den Instituten ITM Dresden, DWI Aachen und DITF Denkendorf organisiert.

Über 60 Vorträge in Plenarsessions und drei Parallelsessions standen auf dem Programm. Expertinnen und Experten aus Wirtschaft und Forschung berichteten über Forschungsergebnisse und marktfähige textile Innovationen in den Bereichen Hochleistungsfasern, Faserverbundwerkstoffe, Medizintextilien, der Funktionalisierung und im Textilmaschinenbau. Die Themen der Konferenz standen im Zeichen der Umbrüche, die durch die digitale Transformation und die Anforderungen einer nachhaltigen Kreislaufwirtschaft von der Textilindustrie bewältigt werden müssen.

Die Möglichkeiten für textile Anwendungen sind groß. Ob Mobilität mit Faserverbundwerkstoffen, Architektur mit modernen Baustoffen oder smarte Textilien für Arbeitsalltag, Gesundheit oder für neue außergewöhnliche Sportarten – es gibt kaum einen Lebensbereich, bei dem High-Tech-Textilien nicht zur Lösung von zukünftigen Herausforderungen beitragen. Die Session „quo vadis Textilmaschinenkonzepte“ zeigte, dass auch bei den Verfahren und Prozessen noch viel Innovationspotenzial besteht und ausgeschöpft wird.

Unter dem Motto „Von der Idee bis zur Praxis“ stellte das Forschungskuratorium Textil e. V. in einer eigenen Transfersession erfolgreiche Kooperationsprojekte aus dem IGF-ZIM-Programm vor, in denen von Vertretern und Vertreterinnen aus Wissenschaft und Industrie gemeinsam Produkte und Verfahren entwickelt und erfolgreich umgesetzt wurden.

Referentinnen und Referenten aus den diesjährigen Partnerländern Portugal und Spanien gaben mit Vorträgen und Diskussionsbeiträgen einen umfassenden Einblick in die Textilindustrie und Forschung der beiden Länder.

Ergänzt wurde das Tagungsprogramm durch eine virtuelle Ausstellung mit Firmen und Instituten sowie über 100 wissenschaftlichen Postern. Drei der Posterpräsentationen wurden mit dem Best Poster-Award der Aachen-Dresden-Denkendorf International Textile Conference 2021 ausgezeichnet.

Etwa 20 Technikerinnen und Techniker und sechs Dolmetscherinnen und Dolmetscher waren im Einsatz, um die Vorträge und Diskussionen in alle Welt zu übertragen. Die nächste ADD International Textile Conference wird wieder wie gewohnt als Präsenzveranstaltung stattfinden. Am 1. und 2. Dezember 2022 lädt das DWI nach Aachen ein.

DiloGroup would like to thank all customers and interested parties for visiting the Dilo booth in Geneva. Despite the existing worldwide Covid, we were able to welcome a great number of well-known faces as well as meet new contacts, among them the most important nonwovens producers from across the world in all application areas: hygiene and lightweight nonwovens, technical textiles and needled nonwovens including geotextiles, filter media and automotive. The interest in using resource saving plant engineering, energy saving and the processing of natural fibres remains.

Dilo presented its latest developments in industry 4.0. Systematic plant monitoring and analysis of machine data allows simplified operation and more effective production. This smart system was illustrated with the aid of live analysis of the performance, quality and availability parameters of the production lines in our Textile Research Centre. The new production systems Hyperpunch Alpha, HyperTex and 3D-Lofter were explained with the aid of videos which led to a very positive responsive from the many different producers which are interested in running trials at the Dilo Textile Research Centre to further explore these subjects. These highlights and further new developments were the basis for fruitful technical discussions.

Stahl, an active proponent of responsible chemistry, has taken an important step toward realizing its target of having lifecycle assessment (LCA) data for all strategic products by the end of 2023. By working closely together with Spin 360, a tech-enabled sustainability consultancy, Stahl has achieved certification of LCA data generation systems, allowing verifiable information to be collected for its products.
LCA is a methodology that measures the impact of any product on the environment over the course of its life. The LCA methodology can provide quantitative data in a format that permits comparisons to be made. The certification of LCA data generation systems is a foundational step to ensuring the accuracy and reliability of future LCA analyses.

Through close collaboration, Stahl and Spin 360 have implemented an Environmental Product Declaration (EPD) system – certified by Bureau Veritas – at Stahl’s site in Palazzolo, Italy. An EPD is an independently verified and registered document that communicates transparent and comparable information about the environment impact of products across their entire lifecycle. This implementation underlines Stahl’s commitment to enabling the sustainable development of its industry by driving accountability and transparency.

Michael Costello, Stahl Group ESG Director: “One of Stahl’s strategic ESG goals is to collect verifiable, high-quality LCA data for its products, thereby paving the way to lowering the environmental impact of the whole supply chain. This EPD system certification is an important achievement, and a key step in realizing this goal. Looking ahead, we’ll continue to work with our partners to enable our certified LCA data availability and shape a better industry.”

Federico Brugnoli, CEO of Spin 360: “We are very proud to have supported this complex process that will ensure the complete reliability of Stahl’s LCA data. Now we will look at the next steps in supporting Stahl, focusing environmental footprint reductions through science-based evolution of the industry. We’re confident that – together – we can ensure a better future for us all.”

Penn Textile Solutions GmbH is one of the world's leading manufacturers of elastic fabrics for under-wear, corsetry, sportswear and swimwear, as well as highly functional textiles for technical applications. The fully integrated company with its own warping, circular knitting, warp knitting, dyeing and finishing facilities currently employs around 150 people.

Penn has long relied on Mahlo
Penn has relied on the cooperation with Mahlo for years. The manufacturer of measuring, control and automation systems for web-shaped goods has decades of experience in the field of process control. Until the summer of 2020, the textile manufacturer had been using a basis weight measurement system in the stenter frame outlet with beta radiation and manual control. "When the krypton preparations had passed their half-life, we had to make a decision: Exchange or replace the system right away", says operations manager Franz Schütte. They sat down with Mahlo representatives and looked for the best solution. Since the systems had already reached a high operating age and the measurement was limited to the basis weight, a new concept was decided upon. "Mahlo made us the best price-performance offer." The new system should be even more efficient and easier to operate for the special makes..

The compression zones of the functional fabric create corresponding distortions within the textile surface in its raw state, which have to be smoothed out in the fixing process. This work is now taken over by a process control system. The Mahlo Famacont PMC-15 with two measuring points automatically controls the leading of the stenter frame by continuously and contactlessly determining the mesh density. In addition, the Patcontrol PCS-20 process control system ensures that the dimensions of the different zones are recorded and also automatically controlled. "The previous beta-radiation facility was not able to collect this kind of data," explains the Penn operations manager. Another important aspect for the textile manufacturer: the complete and costly radiation protection is no longer necessary with the new systems.

Despite very good experience with Mahlo in the past, every change naturally involves a risk. Penn did not have to rely on theoretical considerations, however, but carried out tests in advance with appropriate sample material in the Mahlo test laboratory. The results convinced the decision-makers.

Tonello presents O-Zone, a new garment finishing project developed with Candiani Denim, a leading brand in the denim industry.

O-Zone, just presented at Kingpins 24, represents a new leap in quality and an important step in the growth of Tonello'a range of ozone processes, which are born from direct experience, research and a deeper knowledge of technology.

First with ECOfree2, then with SaniCare and OBleach, now with O-Zone, Tonello are defining ozone finishing and taking it to its maximum expression in every field of application: creation of special effects, garment sanitization, cleaning and reduction of water consumption, etc.

What is O-Zone?
At first glance it is similar to a cabinet. A special cabinet, however, inside which the garments are placed and treated, through an innovative, sustainable, responsible process.

A process that is also flexible, fast, safe and fully controllable by a touch screen that allows you to easily set all the desired parameters to obtain unique and customizable aesthetics, such as localized discoloration and lightening, sun-faded looks and degradé effects.

O-Zone is designed for small productions and is ideal for doing experiments and research directly on the garment, quickly verifying the result.

• DiloGroup looks forward to participating in the Techtextil India show 2021.

DiloGroup offers tailor-made production systems from one supplier and will inform at this forum in the German pavillon about its portfolio and the latest equipment developments from fibre opening to the finished felt.

A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further by using the new needle pattern 8000X which is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

The “3D-Lofter” which was first presented during ITMA 2019 in Barcelona offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts are two examples for this technology which explores new application areas for needlefelts.

The 3D-Lofter technology may also be used “inverted” for filling up bad spots in web mats and thus achieves a better homogeneity of e. g. spunlace, thermobond or airlay products. The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

With more than 370 installations delivered to the nonwovens industry worldwide, DiloGroup has the necessary know-how and the complete equipment portfolio to engineer the perfect production line for any product specification. The efficiency of Dilo production lines is the result of long-term research work and experience. Apart from machines for needling technology we offer in cooperation with partner companies also production lines including thermobonding and hydroentangling components.

Reifenhäuser Reicofil will exhibit at the world's leading nonwovens trade show INDEX in Geneva from October 19 to 22, 2021. Under the slogan "Living Nonwovens", the nonwoven line specialist will showcase solutions for the production of sustainable nonwovens for a wide range of applications.

Sustainable nonwoven production starts with the amount of material used - the less raw material needed, the better. The "Reicofil 5x" line series is specialized in this application and achieves fabric weights of 8 gsm (grams per square meter) or even less through efficient downgauging, even on 1000 m/min Composite lines containing 3 Spunbond beams.

In addition, Reicofil customers can reduce the use of fossil raw materials on request by processing biobased raw materials as an ecological alternative - for example for diapers. The topsheet material, made of bulky, soft, and industrially compostable high-loft nonwovens, meets maximum hygiene requirements at the same time.

For industrial applications, high-strength nonwovens can be processed even from up to 90% PET flakes from post-consumer waste. This is how Reicofil shows ways to combine sustainability and high-performance nonwovens.

In the medical sector, the line manufacturer will also be exhibiting its leading solutions for high-barrier medical protective clothing. In addition, meltblown nonwovens for face masks - still in great demand in many regions due to Covid - provide reliable safety and are helping to combat the pandemic worldwide. Reicofil technology therefore guarantees maximum safety, with filtration efficiencies of up to 99% (N99 / FFP3 standard), minimum quality fluctuations, and extremely high line availability at the same time.

With the current RF5 machine generation, Reicofil also sets benchmarks in terms of quality, performance, availability, efficiency, and machine intelligence - for challenging applications in hygiene, medical, and industrial sectors.

Knopf’s Sohn, a contract finisher of technical textiles, has installed a fully automated Montex stenter at its plant in Helmbrechts, Germany.
Knopf’s Sohn is processing technical textiles for the automotive, aerospace, home furnishings and workwear markets, based on wool, cellulose, polyamide and polyester fabrics, along with elastane blends, in weights of 80-800gsm.

The Montex machinery range is constantly being upgraded to meet evolving customer needs for greater automation, ease of operation and energy optimisation. The latest ten chamber line at Knopf’s Sohn, with a working width of up to 2.0 metres, was engineered to specific requirements in order to accelerate the company’s move to fully automatic control of its production, and high scaffolding was required for its installation.

The line benefits from two integrated ECO Booster modules to provide high energy savings. These compact, air-to-air heat exchangers, installed within the roof structure of the line, exploit energy from the exhaust gas to preheat up to 60% of the incoming fresh air entering the stenter.

The use of a single ECO Booster unit has been calculated to save up to 35% in energy costs, based on fixation processes. Fully automatic operation, set at the Monforts Qualitex control unit, ensures there is no additional burden on the machine operator.

The line is powered by Exxotherm indirect heating, which practically eliminates the yellowing which can be experienced during the treatment of certain polyamide and elastane-based fabrics, and is also equipped with a Conticlean circulating air filter system for constant high drying capacity.

Software
The latest Qualitex visualisation software offers operators reliability and easy control with its full HD multi-touch monitor and slider function, dashboard function with individual adaptation to operating states and faster access to comprehensive recipe data management.

With the Monformatic control system, the exact maintenance of the dwell time in combined treatment processes (drying and heat-setting) can be monitored. When the heat-setting point is reached, the fan speed is automatically adjusted, keeping energy consumption fully under control.
