From the Sector

Mayer & Cie. presented an overview of its current portfolio in the circular knitting sector at the ITM in Istanbul. Two machine types – the SF4 3.2 III and the Relanit 3.2 HS II – and various smart solutions that make circular knitting more efficient were on display. knithawk, a tool for the optical detection of knitting defects, met with interest among the visitors. The same was true for knitlink, Mayer & Cie's hub for digital solutions. Spare parts packages and conversion kits are also in demand for the long-term value retention of Mayer & Cie. machines.

Relanit 3.2 HS II
The Relanit 3.2 HS mechanical single jersey machine offers high productivity, especially in the context of elastic plating. It processes a wide range of yarns and qualities reliably. It is suitable for processing recycled yarns. Their energy consumption is up to a third lower than that of a circular knitting machine with conventional technology.

In Istanbul, Mayer & Cie. presented an updated version of its flagship, the Relanit 3.2 HS II. The new open-width take down is the single component that attracted the most interest. It ensures a uniform pull-off tension of the knitted fabric over its entire circumference. The knitted hose is only opened below the take-down rollers. Furthermore, the take-dwon is equipped with two drives: one for tensioning, one for rewinding. Both can be controlled separately.

Another innovation of the Relanit 3.2 HS is aimed at reducing downtimes: The needle with predetermined breaking point, which was developed together with Groz-Beckert, prevents it from breaking uncontrollably and, in the worst case, breaking needle butt. The new spring sinker is also a joint development with Groz-Beckert. This makes the Relanit 3.2 HS II run more smoothly, produce less noise as well as with less wear and tear.

SF4-3.2 III for lightweight three-tread fleece knitted fabrics
With its SF4-3.2 III, Mayer & Cie. is addressing a trend in the clothing industry that is reflected beyond Turkey: lightweight, elastic three-thread knitted fabrics in both pure cotton and blends.

New Control 5.0 machine control system
Both ITM machine exhibits were on display with the new Control 5.0 machine control system. Control 5.0 is a prerequisite for using knitlink, the hub for Mayer & Cie's digital applications. In this function, the machine control system attracted interest from various large customers.

In the standard SmartControl version, as shown in Istanbul, a so-called Smart Knob is attached to each machine foot. From there, all the functions that the machine operator needs for his work are available. More in-depth settings, such as those made by the knitting manager, are only possible from a mobile device. Any number of Mayer & Cie. machines can be operated from this at the same time.

knithawk
knithawk, a tool for optical defect detection, inspects the knitted fabric as it is produced. It sits in the single jersey machine directly at the knitting point. If knithawk detects a serious or recurring error, the machine is stopped. The tool also creates an error log.

Machine-specific upgrade and conversion kits
With its upgrade kits, Mayer & Cie. brings technological innovations to existing machines. These range from machine-specific upgrades, such as the Performance Kit for existing Relanit 3.2 models to the Senso Blue RS lubrication system.

In addition to the upgrade kits, Mayer & Cie. offers conversion kits for popular machine types. Two are currently available: for the MV4 3.2 II/MBF 3.2 and the S4-3.2 II/ SF4-3.2 III.

As part of the European Erasmus+ project AddTex, the partner organisations organised several hackathons at the universities of Boras (Sweden), UPC (Spain), PIN (Italy) and TUS (Ireland) in May. The aim is to connect students with real challenges in the industry and promote innovation in the areas of ecology, sustainability, digitalisation and design. The participants had received basic information in advance through the 45 training videos and training sessions of the free and public Smart, Digital and Green Skills Academy at https://addtex.eu.

The hackathon at the Italian university PIN (Polo Universitario Città di Prato) was organised and held together with the technical textiles department of the Industrieverband Veredlung - Garne - Gewebe - Technische Textilien e.V. (IVGT). Eight teams competed to develop innovative, sustainable ideas in just a few hours for the German family business Schmitz Textiles GmbH & Co. KG, Emsdetten. Schmitz Textiles, an expert in complete textile solutions for indoor and outdoor use for over 100 years, plans to offer exclusively sustainable products in the medium term and is looking for solutions to continuously increase the existing recycled share of yarns to 100 per cent.

Stefan Schmidt from IVGT presented the challenge via Teams Conference: "We are looking for a new business model for textile recycling at awning manufacturer Schmitz-Textiles in order to increase the existing proportion of recycled yarns and go beyond the exclusive use of recycled PET bottles. Schmitz Textiles has had an awning fabric made from 100% recycled polyester in its range since the end of 2023. The medium-term goal is to switch the entire range of awning fabrics to 100% recycled yarns. The company is looking for suitable solutions to achieve this.

In small teams, the 30 students specialising in eco-design, textiles/sales and textiles/technology developed proposals and presented them in five-minute online pitches. Ralf Bosse for Schmitz Textiles and Iris Schlomski for the IVGT acted as the jury and assessed the individual presentations in the categories of degree of innovation, presentation, industrial application potential and potential for commercial success. Each idea presented and each presentation scored more or less points in the individual categories. In the end, the points scored were added up to determine the winning team, which can further develop its idea together with the company. For Schmitz Textiles, these are Eleonora Boccherini, Ilaria Ioja, Giorgio Gacci and Marianna Butera.

CARBIOS and TOMRA Textiles, a tech venture set up by the sorting technology company TOMRA, announce the signing of an agreement to collaborate on establishing an efficient stream in Northern Europe from textile waste collection, sorting and preparation to recycling using CARBIOS’ enzymatic depolymerization technology at its first commercial plant currently under construction in Longlaville, France

The monomers obtained will be used to produce recycled polyester (r-PET) fiber, closing the loop for polyester textile circularity.

The innovations from both TOMRA Textiles and CARBIOS contribute to addressing critical gaps in the value chain and significantly increase textile-to-textile recycling from its current rate of 1%¹. By accelerating a circular economy for polyester, a sustainable alternative to incineration or landfill is made available.

TOMRA Textiles is on a mission to close the gap in textile circularity, by contributing to designing and scaling textile sorting plants. Under this partnership agreement, TOMRA Textiles will explore specific, tangible measures to enable the preparation of post-consumer polyester waste for biorecycling according to CARBIOS’ specifications.

CARBIOS' biorecycling technology involves breaking down polyester fibers into their basic components using enzymes, which are then used to produce high-quality recycled PET materials such as fibers for the textile industry. The breakthrough collaboration with TOMRA will redirect the challenging PET fraction of polyester textile waste towards biorecycling, showcasing a mutual dedication to pioneering recycling solutions for a circular economy.

INDA, the Association of the Nonwoven Fabrics Industry, applauds the U.S. House of Representatives for passing the Wastewater Infrastructure Pollution Prevention and Environments Safety (WIPPES) Act (H.R. 2964). The WIPPES Act, which creates national standards for “Do Not Flush” labeling for non-flushable wipes, passed out of the House Committee on Energy and Commerce in December of 2023, and on June 12, it cleared the House floor in a bipartisan vote. The bill now awaits consideration in the Senate Science, Commerce, and Energy Committee.

This bipartisan legislation is intended to address the growing problem of sewer system clogs caused by improper disposal of consumer wipes that are not intended to be disposed of in toilets. This federal solution is the result of a years-long industry collaboration with wastewater operators which has resulted in the passage of similar legislation in seven states. The WIPPES Act will create a national standard based on existing state laws to ensure non-flushable wipes will carry prominent “Do Not Flush” labeling on packaging.

“INDA has championed this legislation for the past two years and we are encouraged to see it pass out of the House. We extend our thanks to the bill sponsors, our industry and wastewater partners, and INDA members as we take another step forward to make “Do Not Flush” labeling nationwide,” said Wes Fisher, Director of Government Affairs.

The WIPPES Act lead sponsors in the House are Representative Lisa McClain (R-MI) and Representative Mary Peltola (D-AK) and the bill was introduced in the Senate by Senator Jeff Merkley (D-OR) and Senator Susan Collins (R-ME).

Beaulieu International Group is investing €5 million to transition the fossil based energy supply of its Cushion Vinyl production plant in Wielsbeke, Belgium, to bio mass generated steam supply. A transition to renewable energy. To this end, B.I.G. is collaborating with A&U Energie, a company that converts non-recyclable wood waste into green energy and heat. This strategic move aligns with B.I.G.'s commitment to reach ‘net zero’ for their operations by 2030.

The transition from fossil energy to green steam and the switch to waste gas treatment without direct fossil energy brings significant benefits. First, the switch in technology will lead to 88% reduction in their Belgian Cushion Vinyl carbon footprint related to heat supply and waste gas treatment, compared to the current emissions. Second, the use of steam heating and electric energy provides improved energy efficiency. In addition, the use of steam systems is known for its safety and reliability, providing a safer and more stable heating solution for the Belgian Cushion Vinyl facility. Moreover, the switch to steam and electric energy allows for the use of green electricity in the future, if available.

In addition to transitioning to 100% green energy, Beaulieu International Group is also dedicated to advancing the circular economy. These efforts encompass various initiatives, including increasing the use of recycled and reused materials. For example, 50% of B.I.G.'s PVC floor coverings are already fully recyclable. Additionally, they are actively working to reduce the environmental impact of their solutions by 42% at the end of their life cycle, striving to minimize product emissions to nearly zero, and eliminating pollutants. Recently at the Belgian Flanders Flooring Days, Beauflor launched its Twilight collection, a cushion vinyl floor created with PVC from 100% bio and circular sources resulting in a 40% reduced CO₂ footprint compared to their conventional heterogeneous CV flooring for residential applications

Furthermore, their cushion vinyl brand Beauflor launched the ReLive concept, a specialized program designed for a circular future, ensuring the collection, sorting, and recycling of PVC flooring cutting waste. Currently, this program focuses on post-installation waste and is exclusively available in France, with the goal of expanding its reach to other EU countries.

Through the establishment of strategic partnerships dedicated to finding innovative ways to repurpose waste materials previously slated for incineration, B.I.G. underscores its commitment to sustainable solutions and collaboration with like-minded organizations. 75% of B.I.G.'s post-industrial waste is now being successfully recycled.

The Lectra Group company announced a new collaboration between TextileGenesis, the textile traceability platform and the Forest Stewardship Council (FSC®). It will enable the implementation, via the TextileGenesis platform, of new solutions to ensure the traceability of cellulose fibers from responsibly managed forests.

In fashion, many textiles such as viscose, lyocell and modal use man-made cellulose fibers. These fibers are themselves made from wood pulp, the production of which can contribute to deforestation.

Founded in 1994, the Forest Stewardship Council (FSC®) is an international NGO whose mission is to promote responsible forest management worldwide. In particular, the organization offers certification for products and raw materials which have been obtained from wood grown in responsibly managed forests, and comes from supply chains where social rights of workers, communities and indigenous peoples have been safeguarded.

Amit Gautam, founder and CEO of TextileGenesis, explains: "We've already been working with Man Made Cellulosic Fiber Producers for several years to facilitate, thanks to our blockchain-inspired technology, the traceability of fibers manufactured by the most virtuous producers, and we've integrated their analysis criteria into our platform. By also becoming an FSC® partner today, we're taking things a step further. This new collaboration will support companies in the traceability of FSC certified fibers and support the administration and data management of FSC Chain of Custody certification. All players in the value chain will benefit from increased transparency and much more reliable upstream data. Fashion brands will be able to demonstrate much more easily that their garments use textiles made from responsibly sourced man-made cellulose fibers."

Fabian Farkas, FSC International Chief Commercial Director, adds: “We are seeing a rapid increase in interest in FSC certification from the textile industry, marking a very positive trend. Through this collaboration with TextileGenesis, we aim to simplify the administrative part of FSC certification for companies within the textile supply chain by automating many required data processes. Our goal is to empower brands to identify opportunities for seamless progress in meeting their FSC procurement policies.”

Following the signature in October 2023 of a memorandum of understanding with the International Cotton Association (ICA) and the launch last January of two consortiums with footwear and leather players, and more recently the announcement of its partnership with the Aid by Trade Foundation (AbTF), the initiator of The Good Cashmere Standard® (GCS), TextileGenesis confirms, with this new collaboration with the FSC®, its central place in the ecosystem of players mobilizing for more sustainable and responsible fashion.

The Western Development Commission (WDC) announces the successful funding of the THREAD project. Supported by the Interreg Northern Periphery and Arctic Programme, THREADs (Textile and Habiliment Reuse for the Environment and NPA Area Development) is set to launch a transformative three-year initiative starting in September 2024, focusing on innovative textile waste management.

THREADs aims to significantly reduce textile waste in the Northern Periphery and Arctic region. With a total budget of €1.5 million, the project will implement a range of innovative approaches across the textile lifecycle—from design to disposal. This initiative includes trialling smart waste collection methods, enhancing circular practices, and integrating social inclusion initiatives in circularity efforts. Additionally, the project will explore new business models to support sustainable practices.

The project unites a diverse group of partners from across Europe, reflecting a collaborative effort to tackle an urgent environmental issue. The lead partner, Kajaani University of Applied Sciences from Finland, is joined by other key stakeholders including the Municipality of Kittilä, Kiertokaari Ltd, Remiks Husholdning AS from Norway, Technological University of the Shannon – Forge Design Factory from Ireland, University of Boras and Lulea Miljoresurs AB from Sweden, and the Icelandic Textile Center.

The funding announcement marks a crucial step towards implementing effective solutions that address both the environmental impact of textile waste and the challenges posed by fast fashion in sparsely populated areas. By focusing on sustainability and efficient resource use, THREADs is poised to create meaningful change in the way textile management is approached in the NPA region.

A new type of pure synthetic leather meets the requirements of the European Ecodesign Regulation. Made from a bio-based plastic, it is biodegradable and meets the requirements for a closed recycling process.

Many synthetic leathers consist of a textile substrate to which a polymer layer is applied. The polymer layer usually consists of an adhesive layer and a top layer, which is usually embossed. The textile backing and the top coat are usually completely different materials. Woven, knitted, or nonwoven fabrics made of PET, PET/cotton, or polyamide are often used as textile substrates. PVC and various polyurethanes are commonly used for coatings. The use of these established composite materials does not meet today's sustainability criteria. Recycling them by type is very costly or even impossible. They are not biodegradable. The search for alternative materials for the production of artificial leather is therefore urgent. In 2022, the EU adopted the Sustainable Products Initiative (SPI) ("Green Deal"). It includes an eco-design regulation that considers a product's life cycle in the conservation of resources. For textile and product design, this means incorporating closing the loop or end-of-life into product development.

In an AiF project carried out in close cooperation between the DITF and the Freiberg Institute gGmbH (FILK), it has now been possible to develop a synthetic leather in which both the fiber material and the coating polymer are identical. The varietal purity is a prerequisite for an industrial recycling concept.

The aliphatic polyester polybutylene succinate (PBS) was recommended as the base material because of its properties. PBS can be produced from biogenic sources and is now available on the market in several grades and in large quantities. Its biodegradability has been demonstrated in tests. The material can be processed thermoplastically. This applies to both the fiber material and the coating. Subsequent product recycling is facilitated by the thermoplastic properties.

In order to realize a successful primary spinning process and to obtain PBS filaments with good textile mechanical properties, process adjustments had to be made in the cooling shaft at the DITF. In the end, it was possible to spin POY yarns at relatively high speeds of up to 3,000 m/min, which had a tenacity of just under 30 cN/tex when stretched. The yarns could be easily processed into pure PBS fabrics. These in turn were used at FILK as a textile base substrate for the subsequent extrusion coating, where PBS was also used as a thermoplastic.

With optimized production steps, PBS composite materials with the typical structure of artificial leather could be produced. Purity and biodegradability fulfill the requirements for a closed recycling process.

KARL MAYER GROUP has developed a sophisticated system for considerable energy savings when operating the cylinder dryers in its PROSIZE® sizing machines and BLUEDYE dyeing plant.

Saving costs with inline energy recycling
The innovation is called CASCADE and focuses on steam as a heating medium in cylinder dryers. And for good reason: according to the IPCC report by ITMF Zurich, one tonne of steam cost between USD 20 and just under USD 27 internationally in 2021. The new solution relies on reuse to reduce the amount of process energy required.
"CASCADE recirculates parts of the process steam in cylinder dryers, enabling genuine, efficient energy recycling within the machine," explains Karl-Heinz Vaassen, Head of Textile Drying at KARL MAYER.
The customer benefits from significantly lower energy costs and CO2 emissions. With a view to the Asian market, a dryer with 14 cylinders and a running time of 7,000 working hours can achieve cost savings of up to USD 17,000 per year.

Precise, real savings values are available when looking at the machine dashboard. A sensor provides real-time data on the amount of steam circulating in the circuit, from which the corresponding reduction in CO2 equivalents can be calculated.

Utilizing the pressure drop
CASCADE reuses part of the invested process energy and uses the flash-steam in conjunction with the pressure ratios, which - nomen est omen - decrease in cascades in the different zones of the cylinder dryer.
The highest working pressure prevails in the first cylinder section. The heat transfer medium steam emits large amounts of energy for yarn drying and condenses without temperature loss.

The resulting hot condensate is not immediately discharged from the machine, but is instead fed into a flash tank, where vapor exhaust is formed as a result of the pressure reduction. In conventional systems, the carrier medium for gases is only created in the return line towards the boiler house and is eliminated as undesirable. Instead of being utilised in the process, it escapes into the environment. With the CASCADE system, this "freshly recycled steam" is used for the heat supply in the second cylinder section, but not without prior treatment.

In the system patented by KARL MAYER, the recycled steam is intelligently mixed with live steam and thus raised to the level of the required process conditions for use in the cylinder section at the end of the dryer. Here, the fabric moisture is reduced to the desired residual value at medium pressure and temperature conditions.

Market launch is underway
CASCADE was filed for patent by the KARL MAYER GROUP. It was published in September 2023.
The innovative solution at no extra charge was presented at ITM 2024 in Istanbul and was a visitor highlight at the KARL MAYER GROUP stand.

From January 2024, CASCADE will be part of the PROSIZE® as standard. The first sizing machine with the upgrade for greater energy efficiency will be delivered in the second quarter of this year. It will go to a manufacturer in Europe. In the next step, CASCADE will be integrated into other dryer types and will also be available for the BLUEDYE.
