From the Sector

Stratasys Ltd. announced the launch of its Direct-to-Garment (D2G) solution for the J850 TechStyle™ printer, the newest offering in the Stratasys 3DFashion™ direct-to-textile printing technology. The first example of its application is an Urban Tattoo denim collection which will be revealed at the Texprocess exhibition in Frankfurt, Germany on April 23.

The D2G solution is ideal for customization and personalization by enabling the application of full color multi-material 3D print directly on fully assembled garments of various fabric types including denim, cotton, polyester, and linen. It allows fashion brands to facilitate personalized and bespoke designs for customers, including the ability to tailor 3D prints according to individual preferences, sizes, and styles.  

Available in two sizes, the D2G tray kits facilitate the personalization of garments ranging from jeans to jackets, enabling designers and manufacturers to adopt more sustainable practices by reducing material waste. The seamless workflow delivers ease of calibration and compatibility with various garment sizes, streamlining the production process and fostering the creation of unique, personalized apparel.

Demonstrating this innovation, the Urban Tattoo collection showcases the potential and the ease of direct-to-garment 3D printing. Working with noted designers Karim Rashid, Travis Fitch, Zlatko Yanakiev at Meshroom along with Foraeva Studio, this collection shows the transformation of ordinary garments into pieces of wearable art, imbuing them with personal identity and meaning.

Like body tattoos, Urban Tattoos promote a deeper emotional connection, encouraging the upcycling of existing garments and contributing to a more sustainable fashion ecosystem. This aligns with Stratasys’ strategy for Mindful Manufacturing™. Stratasys has been able to create a new collection that will appeal to multiple brands that reach across diverse socio-economic backgrounds.

The exhibition “Acquired! Shaping the National Design Collection” at Cooper Hewitt, Smithsonian Design Museum, which opened on 16 March, features a STOLL work that has been part of the museum’s permanent collection since 2017.

Visitors can expect more than 150 works that have been compiled from the museum’s collection and new acquisitions since 2017. The selection, which includes works by design pioneers of the recent past, also includes a highly functional balaclava from STOLL.

Blend of design and functionality.
The flat knitted balaclava from STOLL is part of an exhibition area that visualises the defining themes of our time. Alongside a hijab, it stands for considering inclusivity in design. The balaclava offers protection from extreme cold, is stylish and is the result of a combination of creativity and technology.

The balaclava integrates an NFC chip for near-field communication, a heater to warm breathable air, a positive and negative power connector and reflective strips for passive visibility, all knitted directly into the fabric. STOLL’s state-of-the-art flat knitting technology is the basis for straightforward integration. Circuits and conductive yarns can also be incorporated in a fully automated process exactly where they are needed.

Other performance features do not require additional components. A knitted-to-shape 3D design – made possible by the goring technique – offers a perfect fit by following anatomy and eliminating the need for complex tailoring.

STFI will be presenting high-end textile products and solutions at Techtextil 2024. The highlights from current research results and innovations provide an insight into the digitalisation of textile production, show applications for 3D printing and smart technical textiles and provide examples of particularly sustainably designed products as well as innovative approaches for protective and medical textiles.

The central highlight of STFI's presence at Techtextil is a robot system that demonstrates the automated processing of a bobbin frame on a small scale. The pick-and-place application demonstrates camera-supported gripping of the bobbins. The robot is part of the STFI's “Textile Factory of the Future” which demonstrates automation solutions for the textile industry in a laboratory environment.

From the field of sustainable products and solutions, a sleeping bag with bio-based and therefore vegan filling material and a natural fibre-based composite element for furniture construction, in which LEDs and capacitive proximity sensors for contactless function control have been applied using embroidery technology, will be on show. Printed heating conductor structures demonstrate current research work for the e-mobility of the future, as the individually controllable seat and interior heating should ultimately reduce weight and save energy compared to conventional heating systems.

While a protective suit for special task forces protects against the dangers of a Molotov cocktail attack, a shin guard and a knee brace with patellar ring illustrate the process combination of 3D printing and UV LED cross-linking. Other highlights from lightweight textile construction include the rib of a vertical rudder of an Airbus A320 and a green snowboard made from recycled carbon fibres.

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.

Nearly 8,000 international visitors came to meet the 1,300 exhibitors at Texworld Apparel Sourcing Paris. This year's event was enhanced by a boldly designed showcase in the heart of Paris.
The offer was broader, more diversified and more accessible. Despite increasing requirements in the industry, visitor numbers remained stable. It was on these two objective notes that the latest edition of the Texworld and Apparel Sourcing Paris trade shows for the fashion industry came to a close, held from 5 to 7 February 2024 at the Paris Expo Porte de Versailles. During these 3 days, nearly 8,000 visitors came to meet 1,300 weaving and clothing companies from 25 countries on the two levels of Hall 7 (7.2 and 7.3).

Visitors: a Euro-Mediterranean Top 5
This unprecedented concentration of international companies in Europe, which exceeds in number that of February 2019, is a reminder of the central role of European markets for the global fashion industry. This position is confirmed by the weight of buyers from the Euromed zone in the visitor structure: Top 5 is concentrated around buyers from France (20% of the total, up sharply on 2023), the UK (8.3%), Italy (7.9%), Turkey (7.2%) and Spain (6.8%). This Parisian event is proving to be an essential point of contact between designers, buyers and suppliers of fabrics or finished products.

Making the offer ever more accessible “Despite the slowdown in the clothing market, Europe remains a major market for textile and finished goods manufacturers" explains Frédéric Bougeard, President of Messe Frankfurt France. “For some players, it is becoming a strategic market to offset the uncertainties weighing on the Russian and American markets" he continues. Our mission is to fulfill our role as a market place, to adapt to these changes and to make the international offer more and more accessible." The February event also highlighted near sourcing. Nine Ukrainian companies grouped together under the banner of the Ukrainian Association of Textile and Leather Industry Companies (Ukrlegprom), as well as Bulgarian, Italian and Dutch companies, were able to take advantage of the show's visibility to include their expertise in the sourcing plans of French and European buyers.

Texworld Apparel Sourcing Paris, a new name for our trade fairs
Reflecting the adaptation of Messe Frankfurt France's strategy to changes in the market, Texworld Evolution Paris is changing its name to Texworld Apparel Sourcing Paris. This move reflects developments in fashion sourcing and the expansion of brand universes. A growing number of buyers now want to be able to select materials, while also sourcing finished products directly to complement collections or expand their range. The new name is accompanied by a new dual baseline - Weaving the future; sourcing I business I solutions - to underline these developments and reinforce the fairs' service-led positioning.

From 1 to 3 July 2024 at Porte de Versailles
This new signature will be fully expressed at the next edition of Texworld Apparel Sourcing Paris, including Avantex and Leatherworld, which will take place from 1 to 3 July 2024 in Hall 7 (7.2 and 7.3) of the Paris Expo Porte de Versailles. The show, which will remain the same size and offer a more selective range of products, will reflect this convergence between textiles and finished products. This session will also have no interaction with the Paris 2024 Olympic Games, which are due to open on 26 July, three weeks after Texworld Apparel Sourcing Paris

A new research project links some of Denmark's leading researchers in PFAS remediation with artificial intelligence. The goal is to develop and optimise a new form of wastewater and drinking water treatment technology using artificial intelligence for zero-pollution goals.

In a new research and development project, researchers from Aarhus University aim to develop a new technology that can collect and break down perpetual chemicals (PFAS) in one step in a purification process that can be connected directly to drinking water wells and treatment plants.

The project has received funding from the Villum Foundation of DKK 3 million, and it will combine newly developed treatment technology from some of Denmark's leading PFAS remediation researchers with artificial intelligence that can ensure optimal remediation.

"In the project, we will design, construct and test a new, automated degradation technology for continuous PFAS degradation. We’re also going to set up an open database to identify significant and limiting factors for degradation reactions with PFAS molecules in the reactor," says Associate Professor Xuping Zhang from the Department of Mechanical and Production Engineering at Aarhus University, who is co-heading the project in collaboration with Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering.

Ever since the 1940s, PFAS (per- and polyfluoroalkyl substances) have been used in a myriad of products, ranging from raincoats and building materials to furniture, fire extinguishers, solar panels, saucepans, packaging and paints.

However, PFAS have proven to have a number of harmful effects on humans and the environment, and unfortunately the substances are very difficult to break down in nature. As a result, the substances continuously accumulate in humans, animals, and elsewhere in nature.

In Denmark, PFAS have been found in drinking water wells, in surface foam on the sea, in the soil at sites for fire-fighting drills, and in many places elsewhere, for example in organic eggs. It is not possible to remove PFAS from everything, but work is underway to remove PFAS from the groundwater in drinking water wells that have been contaminated with the substances.

Currently, the most common method to filter drinking water for PFAS is via an active carbon filter, an ion-exchange filter, or by using a specially designed membrane. All of these possibilities filter PFAS from the water, but they do not destroy the PFAS. The filters are therefore all temporary, as they have to be sent for incineration to destroy the accumulated PFAS, or they end in landfills.

The project is called 'Machine Learning to Enhance PFAS Degradation in Flow Reactor', and it aims to design and develop an optimal and permanent solution for drinking water wells and treatment plants in Denmark that constantly captures and breaks down PFAS, while also monitoring itself.

"We need to be creative and think outside the box. I see many advantages in linking artificial intelligence with several different water treatment technologies, but integrating intelligence-based optimisation is no easy task. It requires strong synergy between machine learning and chemical engineering, but the perspectives are huge," says Associate Professor Zongsu Wei from the Department of Biological and Chemical Engineering at Aarhus University.

A collaboration between Deakin University researchers and Australia’s largest commercial linen supplier Simba Global is tackling a critical global issue, the spread of harmful microplastics through our laundry.

Clothing and textiles are estimated to generate up to 35 per cent of the microplastics found in the world’s oceans, making them one of the biggest contributors. But there is still a lot to be learnt about the characteristics of these microplastics and exactly how and why they are generated.

Researchers at the ARC Research Hub for Future Fibres in Deakin’s Institute for Frontier Materials (IFM) have teamed up with Simba Global, a global textile manufacturing and supply company, to better understand the extent and type of microplastics shed when their products are laundered. Simba Global wants to lead the charge to reduce the environmental impact of textiles.

Lead scientist IFM Associate Professor Maryam Naebe said working with an industry partner on the scale of Simba Global meant the research could have a huge real-world impact.

Simba Global is the major linen supplier to Australia’s hospitals, hotels and mining camps, resulting in 950,000 tonnes of textile products – including bedsheets, bath towels, scrubs and much more – going through the commercial laundering process each year. It also supplies international markets in New Zealand, Singapore and the US.

“As part of our research, we will investigate potential solutions including the pre-treatment of textiles to reduce the shedding of microplastics, or even increasing the size of the plastics that break down so they can be better captured and removed by filtration during the laundering process,” Associate Professor Naebe said.

“Microplastics are now ubiquitous in the environment, they’re in the air we breathe, the food we eat and the earth we walk on. The magnitude of the problem is bigger than previously thought.

“Of serious concern is the mounting evidence that microplastics are having a negative impact on human and animal health. There are not just physical, but chemical and biological impacts.”

Associate Professor Naebe’s team have taken the first steps in the project, analysing wastewater samples from commercial laundries with high-powered electron microscopes in their Geelong laboratory, part of the largest fibres and textiles research facility in Australia.

The team recently presented a new scientific paper at the Association of Universities for Textiles (AUTEX) Conference 2023, which started the important process of formally categorising these types of microplastics, as well as developing standard terminology and testing methods.

“Because our understanding of microplastics is still in its infancy, we needed to start right at the beginning,” Associate Professor Naebe said.

“We need to have a standard definition of what is a microplastic. Up to this point that has been lacking, which makes it difficult to compare and incorporate other studies in this area.

“We are now developing a systematic method for sampling and identifying microplastics in laundry wastewater. It has been tricky to measure the different sizes, but this is important information to have. For example, there are studies that suggest some sizes of microplastics are causing more issues in certain animals.

“The next step will be establishing an essential method to prevent the release of microplastics from textile laundering. This may involve a coating on the surface of the textile or better ways to collect the waste during the washing process.”

Simba Global Executive Chair Hiten Somaia said the company had a strong focus on sustainability, driven by the business’ purpose statement.

“We are proud to partner with Deakin University in what is the first significant research into textile microplastic pollution in Australia. What we are most excited about is sharing the results of this research with all other textile markets in Australia – including clothing – and putting an end to microplastic pollution from textiles.”

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, has received an initial payment of €1.2 million from the French Agency for Ecological Transition (ADEME) for the OPTI-ZYME research project, carried out in partnership with INRAE2, INSA3 and CNRS4 via the TWB5 joint service and TBI6 research units, a project co-funded by the French State as part of France 2030 operated by ADEME. With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.

Lectra will now directly manage the production of its cutting equipment manufactured in China, primarily dedicated to its Asian customers. The Suzhou site, located to the west of Shanghai, will thus benefit from the standards of operational excellence already implemented by Lectra at its two other plants in Bordeaux-Cestas, France, and Tolland, USA.

Lectra's teams have over 35 years’ experience in the Asia-Pacific region, which in 2022 generated 25% of the Group's revenues.

Since the acquisition of its competitor, Gerber Technology, in 2021, Lectra had been relying on a plant belonging to Dutch group VDL Groep (VDL), to manufacture Gerber-brand multi-ply cutters and spreaders.

For its industrial activities, Lectra aimed to adopt the same standards of operational excellence in China as those currently in effect at its Bordeaux-Cestas and Tolland sites. The Group therefore created a new subsidiary, Suzhou Lectra Equipment Manufacturing Co. Ltd., to take over from subcontractor VDL as of December 1, 2023.

Following the takeover of in-house production at the Tolland site in October 2022, the creation of the Suzhou Lectra Equipment Manufacturing Co. Ltd. subsidiary marks a new milestone in the deployment of Lectra's industrial excellence strategy on a global scale. The Group intends to give priority to regional industrial production, which is beneficial to the local economy.

Mahlo GmbH + Co. KG will present its systems and solutions for efficient and high-quality textile production and finishing together with Shanghai Kuantex at ITMA Asia (November 19 and 23). The focus will be on the machine manufacturer's new straightening concept, the Orthopac RXVMC.

"In the new straightening concept, special attention was paid to the straightening mechanics and their interaction with the analysis electronics of the probe system," explains Sales Manager Thomas Höpfl. The control concept is also new. A probe group at the leveler infeed detects distortions even before they reach the correction rolls. In this way, the rolls are brought directly into position and the fabric is corrected from the very first centimeter. A scanner group at the outfeed also detects possible residual distortion, which is corrected at the second straightening module. This enables an even more precise and faster response when it comes to reacting to rapidly changing distortions. The Orthopac RXVMC therefore shows its full strength when straightening knitwear and fabrics sensitive to distortion.

Also contributing to high-quality textile production and finishing is the Famacont PMC for controlling weft and stitch course density, which will also be on show at ITMA Asia. The Famacont PMC-15 uses a sensor to measure the yarn or stitch density and compares it with the target value stored in the recipe data management system. The detected deviation of the yarn density from the target value is used to fully automatically regulate the leading during the needling process on the stenter frame. Interested parties can have the mode of operation explained to them at the Mahlo booth with the help of a demo tower and their own or provided fabric samples.

Another major topic remains Industry 4.0, because the best measured data is of no use if it cannot be utilized. Mahlo has continuously developed its digital environment mSmart. "Our systems generate data that the customer can use immediately to regulate goods on-line. At the same time, all measured values are backed up in our data management system mLog enhanced and can be retrieved at any time. With this historical data, processes can be optimized and weak points in the process can be minimized," explains Sales Manager Thomas Höpfl.
