Sustainability of process efficiency being among the most pressing ones.

The Dutch company Knitwear Lab helps visions become reality. The creative think tank offers capacities in the areas of R&D, design, knitwear development and production of prototypes and small quantities and has thus implemented a wide range of projects in recent years. The objects range from medical products and high-tech sportswear to smart textiles with integrated sensors. Sustainability activities are also part of the repertoire, such as the production of yarns from recycled waste.

Knitwear Lab operates at two locations for its diverse tasks: Almere in the Netherlandsis available for development work. In Istanbul, there is a branch for production. Both Knitwear Lab sites each have five STOLL flat knitting machines, including models from the modern ADF range. Prototypes are produced in Almere and there is small-scale production. The production plant in Istanbul specializes in the manufacture of high-quality knitwear in small quantities. STOLL is also involved in the creative processes. For the industrial development of knitwear, Knitwear Lab offers Virtual Knitting, a revolutionary method that combines virtual and physical elements of pattern development and knitwear production to reduce waste and pre-production steps. Customers can use Virtual Knitting to create realistic, producible collections, simplify their design iteration processes and take advantage of the wide range of real-life colorways. The basis for this is comprehensive knitwear expertise, the latest 3D software and the CREATE PLUS patterning software, which was developed by STOLL together with KM.ON.

"The 3D visualization of CREATE simplifies communication with the customer considerably. We use this function every day," says Annika Klaas, Senior Knitwear Programmer. She personally appreciates the uncomplicated grading and exchange of stitch dimensions and the much faster and more efficient work with Dimensioned Shapes that this makes possible. This helps her in her day-to-day work. "We often have requests to realize the same product in different yarns, which now works much faster," says the programmer. Further simplifications would include minor optimizations in terms of the efficiency and user-friendliness of programming and additional import and export options for shapes. Discussions on implementation are already underway.

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.”

The kick-off meeting for the "Trends and Design Factors for Hydrogen Pressure Vessels" project, recently held at AZL Aachen GmbH, was a successful event, bringing together more than 37 experts in the field of composite technologies. This event laid a solid foundation for the Joint Partner Project, which currently comprises a consortium of 20 renowned companies from across the composite pressure vessel value chain: Ascend Performance Materials, C evotec GmbH, Chongqing Polycomp International Corp. (CPIC), Conbility GmbH, Elkamet Kunststofftechnik GmbH, F.A. Kümpers GmbH & Co. KG, f loteks plastik sanayi ticaret a.s., Formosa Plastics Corporation, Heraeus Noblelight GmbH, Huntsman Advanced Materials, Kaneka Belgium NV, Laserline GmbH, Mitsui Chemicals Europe GmbH, Plastik Omnium, Rassini Europe GmbH, Robert Bosch GmbH, Swancor Holding Co. Ltd. Ltd., TECNALIA, Toyota Motor Europe NV/SA, Tünkers do Brasil Ltda.

The project follows AZL´s well proven approach of a Joint Partner Project, aiming to provide technology and market insights as well as benchmarking of different material and production setups in combination with connecting experts along the value chain.

The kick-off meeting not only served as a platform to foster new contacts and get informed about the expertise and interests of the consortium members in the field of hydrogen pressure vessels, but also laid the groundwork for steering the focus of the upc oming project's ambitious phases. As a basis for the interactive discussion session, AZL outlined the background, motivation and detailed work plan. The central issues of the dialogue were the primary objectives, the most pressing challenges, the contribut ion to competitiveness, and
the priorities that would best meet the expectations of the project partners.

Discussions covered regulatory issues, the evolving value chain and the supply and properties of key materials such as carbon and glass fibres and resins. The consortium defined investigations into different manufacturing technologies, assessing their matu rity and potential benefits. Design layouts, including liners, boss designs and winding patterns, were thoroughly considered, taking into account their implications for mobile and stationary storage. The group is also interested in cost effective testing m ethods and certification processes, as well as the prospects for recycling into continuous fibres and the use of sustainable materials. Insight was requested into future demand for hydrogen tanks, OEM needs and strategies, and technological developments to produce more economical tanks.

The meeting highlighted the importance of CAE designs for fibre patterns, software suitability and the application dependent use of thermoset and thermoplastic designs.

The first report meeting will also set the stage of the next project phase, which will be the creation of reference designs by AZL's engineering team. These designs will cover a range of pressure vessel configurations using a variety of materials and production concepts. The aim is to develop models that not only re flect current technological capabilities, but also provide deep insight into the cost analysis of different production technologies, their CO₂ footprint, recycling aspects and scalability.

AZL's project remains open to additional participants. Companies interested in joining this initiative are invited to contact Philipp Fröhlig.

HeiQ AeoniQ™ becomes an active brand partner of the Canopy initiative with eleven other companies to address the growing climate and biodiversity crises by committing to keep Ancient and Endangered Forests out of our man-made cellulosic fiber supply chain.

The commitments that HeiQ AeoniQ™ is making are part of solutions-driven non-profit Canopy’s Pack4Good and CanopyStyle initiatives which currently represent collectively 950 brand partners. Together, the initiatives are shifting supply chains away from vital forests to low-impact, circular Next Gen Solutions.

“We must rapidly replace oil-based polyester in the textile industry causing microplastics, global warming, landfill and ecosystem degradation. Cellulose is the most abundant biopolymer in the world and is best suited to replace polyester. However, we must pay attention to cellulose feedstock sources. Our forests, a potential cellulose feedstock, are one of the most important solutions to addressing the effects of climate change. Approximately 2.6 billion tons of carbon dioxide, one-third of the CO₂ released from burning fossil fuels, is absorbed by forests every year. Around 12.5% of global greenhouse gas emissions (5-10 GtCO₂e annually) come from deforestation. We are losing forests at an alarming rate. Every year, around 10 million hectares of forests globally are destroyed. We need immediate action to increase forests again. Canopy is our go-to partner to replace polyester with circular & sustainable cellulose feedstock for our innovative HeiQ AeoniQ™ fiber revolution.” said Carlo Centonze, HeiQ Group CEO.

Paper packaging is also a key driver of forest loss globally, as 3.1 billion trees are cut down annually to produce the boxes and bags in which products are packaged and shipped. Paper packaging production has increased by 65% over the past two years.

“The range of companies and sectors represented in today’s announcement reflects the breadth of market response to the growing climate and biodiversity crises and intensifying supply chain disruptions,” said Nicole Rycroft, Founder and Executive Director of Canopy. “Today’s brand partners add significant momentum to global conservation efforts and the movement to transform ‘take, make, waste’ supply chains to be lower-impact and Next Gen.”

Today, as part of Pack4Good, HeiQ AeoniQ™ committed to:

• Eliminate Ancient and Endangered Forests from our paper packaging supply chain.
• Reduce material use through design innovation.
• Maximize recycled content.
• Explore and scale alternative Next Gen fibers (such as agricultural residues).
• Where virgin fiber is necessary, use FSC-certified fiber.

Archroma celebrated 100 years of sulfur dye innovation at its manufacturing and research hub in Castellbisbal, near Barcelona in Spain.

The milestone was marked at an on-site ceremony attended by more than 250 guests, including authorities from the Catalan government, senior Archroma leaders from Spain and overseas, current and former staff, key customers and suppliers and other important stakeholders.

The Castellbisbal site traces its roots back to 1921, when Joan Cardoner Vidal founded a dye manufacturing company that was eventually bought by Sandoz, which was subsequently acquired by Clariant, and later, SK Capital to create Archroma. Its breakthroughs have helped sulfur dyeing technology become a staple in the production of denim, casual wear and workwear fabrics over the past 100 years, with excellent color fastness and cost-efficiency.

Home to a leading research center that has contributed numerous innovations, Castellbisbal is particularly known for the creation of Archroma’s DIRESUL® RDT range in the 1980’s, which entered the market as the first low sulfide pre-reduced sulfur dyes.

Recently, Archroma developed the cutting-edge DIRESUL® EVOLUTION BLACK which enables a significant impact reduction in the dye synthesis, allowing for the creation of new black denim styles.
Among patented technologies from the Castellbisbal-based research team are the DIRESUL® EarthColors and FiberColors dyes, which use waste from the food and textile industries respectively as raw materials. These revolutionary innovations manufactured at Castellbisbal for customers, brands and retailers, help to advance circularity in the textile industry.

Today it is an important hub for large-scale production of synthetic textiles and skilled workforce. The textile Industry in Surat produces est. 25 Million meters of fabrics per day. It is also considered to be the financial capital and the growth engine of Gujarat.

Archroma and Shima Seiki have expanded their partnership to bring the industry’s largest library of colors for cotton and polyester to the SDS®-ONE APEX design, planning and virtual sampling system and APEXFiz® (hereafter SDS®-ONE APEX series) subscription software.

Now offering a total of 5,760 color references, SDS-ONE APEX series has added all 1,440 colors for polyester from The Color Atlas by Archroma® to its color library of 4,320 Color Atlas colors for cotton poplin. The new polyester collection ranges from neutral earth tones to vibrant jewel tones and on-trend fluorescent colors, with shades suitable for sportswear, fashion, home furnishings, automotive textiles and more.

The extended color library in SDS®-ONE APEX series will help designers and manufacturers to visualize and evaluate their design choices on realistic fabric simulations and then put them into production with dyes and finishes that meet their desired sustainability profile. The Shima Seiki system also offers a smooth transition to machine programming for quick and accurate production, reduced waste and accelerated time to market.

Each of the 5,760 Color Atlas color references in the SDS®-ONE APEX series design software is available as a physical color standard that includes precise dyeing recipes and compliance data, as well as access to expert technical support from Archroma around the world.

“Polyester remains the most popular choice across many textile segments where high performance is a must. Users of Shima Seiki’s advanced SDS®-ONE APEX series platform will now be able to select from the industry’s largest library of colors for both cotton and polyester and, more importantly, trust that their choice can be reliably executed,” Chris Hipps, Head of Strategic Business Development, Archroma Color Management, said.

“Our colors are formulated with dyes that comply with international eco-standards and work with Archroma’s groundbreaking coloration systems, like FAST SPORT,” he continued.

Founded in 2013, NOPINZ is a UK-based manufacturer of clothing for cyclists and triathletes. The company's first product was the ‘SpeedPocket’, a product that allows competitors to attach their race numbers more easily (and with ‘no pins’) while improving the all-important aerodynamics. Soon recognising the customer demand for premade attire with incorporated number pockets, the company embarked on a mission to manufacture these new product lines itself. Today, NOPINZ boasts a diverse portfolio, with 60% of its products made in-house, catering to a growing customer base across the UK and international markets. NOPINZ creates speed suits for some of the world’s top cycling teams, as well as competitive amateurs.

NOPINZ places a strong emphasis on sustainability and is committed to minimising its environmental impact. Using a microfactory approach gives better oversight and control of the manufacturing process, including sourcing materials sustainably and locally where possible, reducing transportation, and improving access to recycling. “Our ‘zero to landfill’ policy, means that we reduce our wastage where possible and either recycle or donate excess product to charity,” Blake adds. “We hope to become a B-Corp company in the future.”

“We tested out a few printers, before we ultimately settled on Mimaki,” Blake Pond, the founder of NOPINZ explained. Now the company’s line-up entirely consists of Mimaki’s textile dye sublimation solutions.
“During our search we prioritised the ability to produce fluorescence and accurately replicate colours. Customers often come to us with existing kit made by other manufacturers, which they want to match, so accurately replicating colour is extremely important. And even without existing kit, customers occasionally ask for specific pantone colours. When it comes to cycling kit, colour is often pivotal when considering where to buy from.”

As two flagship dye sublimation printers, both the TS300P-1800 and TS55-1800 are equipped to print on the various technical fabrics that are needed for cycling attire and faithfully reproduce colours to meet customer expectations.

The combination of high strength and rigidity with sustainability and a neutral carbon footprint makes flax the ideal raw material for natural fibre-reinforced plastics. vombaur offers composite textiles made of this natural fibre for the automotive, wind power, construction or sports industries and many other sectors.

Flax fibres are rigid and tear-proof. They have natural bactericidal properties, are virtually antistatic, stain resistant and easy to spin. Humans have taken advantage of these properties to manufacture robust, stain-resistant and lint-free textiles. Between the late 19^th and late 20^th centuries, cotton largely replaced natural fibres. Because flax can be grown in Europe and consumes less energy and water than cotton production, the material's importance is currently growing again, for both clothing and composites. Regional textile value added chains in Europe – flax makes them possible.

Ideal mechanical properties
vombaur makes the mechanical properties of flax usable for lightweight design. Because flax fibres are particularly rigid and tear-resistant, they ensure great stability in natural fibre-reinforced plastics (NFRPs). And thanks to their low density of 1.50 g/cm3, the fibres weigh virtually nothing. On top of this, fibre-reinforced plastics are less prone to splintering than glass fibre-reinforced plastics.

Excellent carbon footprint
The cultivation of flax binds CO₂ and the production of natural fibre-reinforced plastics (NFRPs) generates approximately one third less CO₂ emissions compared with conventional fibre-reinforced plastics. Energy consumption is substantially lower. This saves resources. The use of flax fibre tapes by vombaur in lightweight design applications also improves the product's carbon footprint and contributes to a secure, regional supply chain.

Recycling without impacting on quality
Flax offers another sustainability benefit: more recycling cycles than glass- or carbon fibre-reinforced plastics – without impacting on quality. Thermoplastic fibre-matrix prepregs are melted and reused in the recycling process. The natural fibres can be used in other products such as natural fibre-reinforced injection moulded parts.

Sustainable product developments for many industries
"Orthoses for high-performance sports, high-tech skis, wind turbines, components for the automotive industry or aerospace, but also modern window profiles – the application scope for our lightweight design flax tapes is amazingly diverse", as Carl Mrusek, Chief Sales Officer at vombaur explains. "After all, wherever flax tapes are used, three key properties come together: light weight, strength and sustainability".
