• An innovative European project to process and recycle plastic textile waste
• A partnership to reach the objectives set by the European Union in reducing CO2 emissions by 2030
• A unique consortium rallying 16 public and private European organizations working together for more circular economy

Carbios joined WhiteCycle, a project coordinated by Michelin, which was launched in July 2022. Its main goal is to develop a circular solution to convert complex^[1] waste containing textile made of plastic into products with high added value. Co-funded by Horizon Europe, the European Union’s research and innovation program, this unprecedented public/private European partnership includes 16 organizations and will run for four years.
 
WhiteCycle envisions that by 2030 the uptake and deployment of its circular solution will lead to the annual recycling of more than 2 million tons of the third most widely used plastic in the world, PET^[2]. This project should prevent landfilling or incineration of more than 1.8 million tons of that plastic each year. Also, it should enable reduction of CO2 emissions by around 2 million tons.
 
Complex waste containing textile (PET) from end-of-life tyres, hoses and multilayer clothes are currently difficult to recycle, but could soon become recyclable thanks to the project outcomes. Raw material from PET plastic waste could go back into creation of high-performance products, through a circular and viable value chain.
 
Public and private European organizations are combining their scientific and industrial expertises:

• industrial partners (Michelin, Mandals, KORDSA);
• cross-sector partnership (Inditex)
• waste management companies (Synergies TLC, ESTATO);
• intelligent monitoring systems for sorting (IRIS);
• biological recycling SME (Carbios);
• product life cycle analysis company (IPOINT);
• university, expert in FAIR data management (HVL);
• universities, research and technology organizations (PPRIME – Université de Poitiers/CNRS, DITF, IFTH, ERASME);
• industry cluster (Axelera);
• project management consulting company (Dynergie).

 
The consortium will develop new processes required throughout the industrial value chain:

• Innovative sorting technologies, to enable significant increase of the PET plastic content of complex waste streams in order to better process them;
• A pre-treatment for recuperated PET plastic content, followed by a breakthrough recycling enzyme-based process to decompose it into pure monomers in a sustainable way;
• Repolymerization of the recycled monomers into like new plastic;
• Fabrication and quality verification of the new products made of recycled plastic materials

 
WhiteCycle has a global budget of nearly 9.6 million euros and receives European funding in the amount of nearly 7.1 million euros. The consortium’s partners are based in five countries (France, Spain, Germany, Norway and Turkey). Coordinated by Michelin, it has an effective governance system involving a steering committee, an advisory board and a technical support committee.

According to the World Health Organization (WHO), cardiovascular disease is one of the most common natural causes of death. Every year, it is the cause of death of around 17 million people worldwide. The Peter Dornier Foundation Prize 2022 has now awarded a research work that is to improve the medical care of people with insufficient heart valve function in the future and prolong the patients' lives.

The human heart is a high-performance machine: over the course of a person's life, it beats almost three billion times, pumping around 200 million litres of blood through the body. Enormous stresses that can sometimes lead to life-threatening signs of wear and tear. If a heart valve gets out of step, patients usually get artificial-mechanical or biological valves as a replacement. However, mechanical solutions imply patients to take blood-thinning medication for the rest of their lives. In addition, there may be audible closing noises. For example, almost a quarter of patients with mechanical heart valves complain of sleep disturbances. Biological heart valves, on the other hand, such as those made from animal tissue, require a great deal of manual work and have a shorter lifetime.

Potential of weaving for medical products demonstrated
For this reason, Graduate Engineer Mathis Bruns at the Institute for Textile Machinery and High-Performance Textile Materials Technology (ITM) at the TU Dresden is researching an implant alternative made of fabric. As part of a research project that also involved heart surgeons from the Dresden Heart Centre and the University Hospital in Würzburg, Mr. Bruns provided important findings for weaving an artificial heart valve in his diploma thesis. For his work entitled "Development of tubular structures with integrated valve function", Mathis Bruns has now received the Peter Dornier Foundation Prize 2022, endowed with 5,000 euros. In his laudation, Dr. Adnan Wahhoud, former head of the development department of air-jet weaving machines at DORNIER in Lindau, said: "With his work, the winner of the award demonstrates very clearly the potential of weaving technology to produce fabrics of complex form, geometry and structure with the aim of prolonging and improving people's lives." The award-winning thesis enriches research into three-dimensional tissues for use in medicine.

Weaving replacement heart valves without seams
"A particular advantage of our approach is the integral production method", says foundation prize winner Mathis Bruns. “The geometry and function of a heart valve is that complex that woven heart valves could not be produced in this form previously. Through the combined use of a rigid rapier weaving machine with bobbin shield and a Jacquard machine, it is possible to weave the replacement heart valve in such a way that it no longer has be sewn together. Even the tubular structures for the blood vessels and the integrated valve function are ‘all of one piece’. Seams are always a weak point in textile medical products," Mr. Bruns adds. “Another advantage of the woven heart valve is the possibility to insert it by the help of minimally invasive surgery. Hence, the folded valve which is about the size of a tea light is to be pushed with a catheter via the bloodstream to the target position in the heart and unfolded there. The patient's chest and heart would then no longer have to be cut open”, explains prize winner Mr. Bruns.

Textile structure is similar to human tissue
A wide variety of medical products have always been produced on DORNIER weaving machines. Customers use them to produce fabrics for bandages, prostheses, blood filters and orthoses among other things. For Mathis Bruns, it is only evident that implants such as heart valves will more and more be woven on the machines from Lindau in the future. "Textile tissue is very similar to human tissue," he says. The human body consists largely of thread-like materials, just as a textile fabric is made up of thousands of individual threads. "Muscle fibres convey force impulses, nerve tracts send stimuli such as pain and brain cells convey information via thread-like dendrites and axons." Because of their ‘thread-like properties’, woven implants are therefore particularly suitable for medical applications.

EFI™ Reggiani, the industrial textile printing business of printing technology company Electronics For Imaging, Inc. (EFI), has broken ground on a new textile campus to accommodate ongoing growth. The new 20,000-square-metre campus in Comun Nuovo, Bergamo, Italy, is expected to be completed midyear in 2023.

Sustainability and employee well-being at the centre
The new facility was designed with environmental sustainability and employee well-being in mind. That focus includes plans to install 400 kilowatts of solar panels supplying 60% of the facility’s total energy requirements. Moreover, the building will benefit from superior thermal insulation that will ensure a reduction in heating and cooling costs. Numerous skylights in the facility will provide better natural lighting and a reduction in artificial lighting usage.
 
Green space on the campus was a priority in the design process, covering an estimated 20% of the total area. For a more welcoming work environment, the campus will also feature a canteen and gymnasium for employee use.
 
A 3,000-square-metre demo centre in the new facility will be nearly twice as large as the current EFI Reggiani demo centre in Grassobbio, Italy, offering a high-end, high-tech showcase for state-of-the-art EFI Reggiani printers, as well as Mezzera pre- and post-treatment and Jaeggli yarn treatment products. The demo centre will also feature EFI Reggiani’s recently acquired portfolio of Inèdit raster image processing (RIP) and workflow software solutions.
 
Transforming the textile industry through innovation in green
Since the launch of its first analogue printer, to its newest digital solutions, EFI Reggiani has at its core a heritage and expertise that have contributed to the transformation of the textile industry worldwide. With its total commitment to providing “Innovation in Green,” EFI Reggiani’s leadership is the result of extensive research targeted at improving productivity, quality and sustainability in its customers’ operations. The company is focused on optimising the textile manufacturing process – and reducing energy use, water consumption and overall environmental impact – to ensure customers’ business growth and profitability.
 
Over the years, EFI Reggiani’s product portfolio has continued to expand, ranging from rotary and flatbed printing machines, to scanning/multi-pass digital printers, to fast digital textile printers.

New ideas were exchanged, brainstormed, and discussed freely at members’ booths at the Swiss Textile Machinery Pavilion during the recent Techtextil in Frankfurt. “Customers and researchers met Swiss textile machinery companies to explore the possibility of the not-yet-invented. “We regard our Pavilion as the place where future innovations catch a spark,” says Cornelia Buchwalder, Secretary General of the Swiss Textile Machinery Association. Further developments in the field of hybrid yarns were a hot topic. One example of this involves producing a yarn which has all the typical characteristics and advantages of carbon – but which also prioritizes careful use of resources, combining carbon fibres with thermoplastics.

Technical textiles cover a vast range of applications, and it’s still growing thanks to intensive research by specialist institutes and universities. Many members of the Swiss Textile Machinery Association maintain long-standing partnership with such bodies. Innovations are often joint efforts.

Feel-good technical fabrics
Some technical textiles feel like a second skin. A well-known example is activewear from the ‘sport tech’ field. Activewear includes breathable clothing, usually consisting of a three-layer-laminate: an inner lining, a breathable membrane in the center, and an outer fabric. The challenge is to bond the individual layers without losing breathability or softness, while meeting technical requirements such as resistance to a number of wash cycles.

Bonding solutions meeting top quality requirements, as well as ambitious standards for environmental protection and sustainability, were reinvented by the Cavitec brand from the Santex Rimar Group. This company’s hotmelt technology uses one-component polymers applied to textiles in a hot, molten state. Bonding based on hotmelts is both water- and solvent-free. Drying and exhaust air cleaning are not necessary, which is an ecological advantage. Energy consumption is also significantly lower. Cavitec hotmelt technology is also developed for laminated medical protection fabrics which are safe, high-quality and sustainable. These fabrics can be washed, sterilized, and used again.   

A second skin with added value is the result of Jakob Müller Group’s cooperation with an institute for an established outdoor fashion brand. They have devised a heating mat applied as an inner jacket. Outdoor gear with a heated inlay offers the wearer a comfortable feeling even in a cold climate. The heating mat is particularly light, breathable, flexible and adjustable to three temperature levels.

Fabrics with these advantages are now possible thanks to multi direct weaving (MDW) technology from the Jakob Müller Group. A lacquer-insulated heating strand is inserted into the base textile as a ‘meander’ using MDW technology. The technology is offered with both label weaving machines and the latest generation of ribbon weaving machines. The textile pocket calculator is another MDW based future-oriented application developed in cooperation with a textile research institute.

Safety and health
Life-saving reliability is a must for vehicle airbags. They have to fulfil high security aspects, and must remain inflated for several seconds when an accident occurs. Airbags made of flat-woven fabric – cut and seamed – can show weakness at seams during the inflation phase. Latest Jacquard technology by Stäubli enables one-piece-woven (OPW) airbags to be produced, creating shape and structure in a single process. The final product is an airbag consisting of a sealed cushion with woven seams. OPW airbag weaving reduces the number of production steps, and increases the security aspects.
Another big advantage of Stäubli’s new weaving technology is the flexibility in formats required in today’s mid- and upper-range cars, where lateral protection (in the seat or in the roof over the door) has become standard and is designed in line with the car shape. Safe airbags are woven on modern high-speed weaving machines. The warp material, the variety of fabric patterns, and the importance of precisely shaped airbags require the use of a robust and reliable Jacquard machine.

A revolution for orthopaedic patients is a knitting machine from Steiger Participations, which uses compressive yarns developed to meet the needs of the specific health market. This machine model was exclusively designed for production with inlaid elastic yarns and offers optimum performance with guaranteed final product quality.

In the orthopaedic field, many Steiger flat knitting machines have already been operating as automatic, custom-made production systems. For example, the dimensions of an injured limb are taken by the doctor and fed into a web-based application. The doctor selects the compression class in the various sections of the item and a data file created by the software automatically applies a preconfigured program. With no human intervention required, the program is generated and produced on the machine, precisely matching the patient’s dimensions. Each product is different, and generally available within 48 hours.

Carbios has signed an agreement with On, Patagonia, PUMA, and Salomon, to develop solutions that will enhance the recyclability and circularity of their products.
 
An important element of the two-year deal will be to speed up the introduction of Carbios’ biorecycling technology, which constitutes a breakthrough for the textile industry. Carbios and the four companies will also research how products can be recycled, develop solutions to take-back worn polyester items, including sorting and dismantling technologies, and gather data on fiber-to-fiber recycling as well as circularity models.
 
The challenge the four brands share, is that their ambitious sustainable development goals can only partially be met by conventional recycling technologies which mostly target bottle-to-fiber recycling. Future regulations will require more circularity in packaging and textile. Yet the market consensus is that there will soon be a shortage of PET bottles, as they will be used for circular production methods in the Food & Beverage Industry.   
 
Carbios’ innovative process constitutes a technological breakthrough for the recycling of polyester (PET) fibers, which are widely used in apparel, footwear and sportswear, on their own or together with other fibers. PET polyester is the most important fiber for the textile industry with 52 MT produced, even surpassing cotton at 23MT. The biorecycling process uses an enzyme capable of selectively extracting the polyester, recovering it to recreate a virgin fiber. This revolutionary technology makes it possible to recover the PET polyester present in all textile waste that cannot be recycled using traditional technologies.
 
PET plastics and fibers are used to make everyday consumer goods such as bottles, packaging and textiles. Today, most PET is produced from fossil resources, then used and discarded according to a wasteful linear model. By creating a circular economy from used plastics and fibers, Carbios’ biorecycling technology offers a sustainable and more responsible solution.

Iluna Group is exhibiting at the upcoming Première Vision, from July 5-7, with the aim of promoting a new fashion that combines aesthetic research and environmental responsibility.
 
The key word of this new collection is “experimentation”: the search for new solutions that can offer consumers style, sustainability and well-being translates into innovative blends, natural dyes and smart prints.

This season, the Iluna team is introducing for the first time GOTS-certified organic cotton inside its gallons and allovers, to add a natural touch to its Green Label line. Among the smart ingredients chosen by Iluna Group are Renycle® and Q-Nova, both GRS-certified pre-consumer recycled polyamide yarns, in addition to premium recycled stretch ROICA™ EF by Asahi Kasei. The result is a comfortable and ultralight product that remains true to a high value of creativity and responsibility.

In terms of aesthetic innovation, explorations continue with a yarn blend of FSC-certified viscose and polyamide, resulting in striking new Textronic designs. The 3D effect embossed designs create a cloud effect that, combined with Lurex, shows unexpected glows.

Moreover, the continuous path through the new dimension of responsibility continues in several directions: developments in GRS (Global Recycled Standard) certified recycled yarns aimed at unprecedented effects in both look, performance and hands; experiments with 16 different natural dyestuffs; and continued investment in technologies that can ensure significant savings in water and energy consumption, including GREENDROP, the new GOTS-certified digital pigment printing system.

The ReHubs initiative brings together key European and world players to solve the European textile waste problem by transforming “waste” into a resource, and to boost textile circular business model at large scale.

This collaboration is set to turn the societal textile waste issue into a business opportunity and to fulfil the EU ambitions of the Green Deal, of the mandatory texile waste collection by end 2024 and the transition into Circular Economy.

In 2020 EURATEX launched the ReHubs initiative to promote collaboration across the extended textile value chain and considering all perspectives on chemicals, fibers making, textiles making, garments production, retail and distribution, textiles waste collection, sorting and recycling.

In June 2022 ReHubs completes a Techno Economic master Study (TES) which researches critical information on the feedstock (textile waste) data, on technology, organizational and financial needs to recycle 2.5 million tons of textile waste by 2030 and to effectively launch the ReHubs.

EURATEX’s ReHubs initiative plans to pursue fiber-to-fiber recycling for 2.5 million tons of textile waste by 2030
According ReHubs Techno Economic Master Study (TES), the textile recycling industry could generate in Europe around 15,000 direct new jobs by 2030, and increase need for nearshoring and reshoring of textile manufacturing.

The textile recycling industry in Europe could reach economic, social and environmental benefits for €3.5 billion to €4.5 billion by 2030
“Transform Waste into Feedstock” announced as first project supported by the ReHubs, and aiming at building up a first 50,000 tons capacity facility by 2024.

Europe has a 7-7.5 million tons textile waste problem, of which only 30-35% is collected today.  

Based on the ambitious European Waste law, all EU Member States must separately collect the textile waste in 2 years and half. While some countries are designing schemes to face the waste collection challenge, currently no large-scale plan exist to process the waste.

The largest source of textile waste (85%) comes from private households and approximately 99% of the textile waste was made using virgin fibers.

Euratex  assesses that to reach a fiber-to-fiber recycling rate of around 18 to 26 percent by 2030, a capital expenditure investment in the range of 6 billion € to 7 billion € will be needed, particularly to scale up sufficient sorting and processing infrastructure. The economic, social, and environmental value which could be realized, potentially total an annual impact of €3.5-4.5 billion by 2030.

Once matured and scaled, the textile recycling industry could become a profitable industry with a total market size of 6-8 billion € and around 15,000 direct new jobs by 2030.

Next steps of the ReHubs initiative

• A European textile recycling roadmap proposing Objectives and Key Results to recycle fiber-to-fiber 2.5 million of textile waste by 2030
• A leading collaboration hub with large players and SMEs from across an extended European textile recycling value chain
• A first concrete portfolio of 4 launching projects:
  - Transform textile waste into feedstock
  - Increase the adoption of mechanically recycled fibers in the value chain
  - Expand capacity by solving technical challenges for thermo-mechanical textiles recycling
  - Create capsule collection with post-consumer recycled products

The 1^st project addresses current sorting technologies which have limits to identify materials with sufficient accuracy for the subsequent circular recycling processes. The “Transform Waste into Feedstock” project will focus on further developing and scaling such sorting technologies. The project group led by Texaid AG aims on building up a first 50,000 tons facility by the end 2024.

The viscose specialities manufacturer Kelheim Fibres has won the Techtextil Award in the "New Concept" category for their project "Cellulose-based nonwovens for highly absorbent reusable products".
This award is intended to make cutting-edge developments visible, promote unconventional thinking and intensify the dialogue between researchers, manufacturers.

The starting point for the innovation was the search for a washable and thus reusable absorbent pad made of completely bio-based materials for the cloth diaper of the Berlin-based start-up Sumo.
Two main requirements of the application are obvious: A fast and efficient liquid distribution and high absorbency should minimise rewetting and leakage. Both are ensured by speciality viscose fibres from Kelheim, which have been making this essential contribution to absorbent hygiene products such as tampons for many years. The obvious solution was therefore to optimally utilise the synergies between knitted and woven structures with nonwovens.

In doing so, the advantages of nonwovens in combination with speciality viscose fibres in terms of absorbency (through e.g. more open-pored structures) have been perfectly transferred from the field of disposable to the world of reusable products. For reusable products, however, there is another challenge to overcome: they must remain stable during washing and over several cycles of use. To ensure this, an innovative nonwoven construction was developed in close cooperation with the STFI. These nonwovens can be used as a stand-alone solution or integrated into a textile structure.

The sustainable collaboration and innovation between Indorama Ventures (IVL), Auping and TWE Group presented a certified cradle to cradle process for mattress components across nonwoven applications, at Techtextil, Frankfurt, 21st to 24th June 2022.

Using circular research and design, the industry partnership between IVL Mullagh (Ireland), Auping and TWE Group has resulted in a perpetual, sustainable economic business model, for manufacturers globally. The inclusion of safe raw materials within mattress manufacturing allows the materials to be easily disassembled at the product’s end of use in order to be further reused as same components or recycled into new raw material at the same quality level, to enable versatile textile applications.

Designed for disassembly to optimize the use of existing resources, reduce carbon footprint and support customer objectives all along their customers’ supply chain. This circular industry collaboration begins with design, where the mattress is constructed using only two different base materials, 100% PET polyester textiles and steel wire pocket springs connected with Niaga®️, a non toxic reversible adhesive, making the mattress easy to disassemble and recover.

IVL, Auping and TWE’s shared vision for a better world is demonstrated through their connected and innovative circularity that helps to close the loop. Auping collects, sorts and separates the collected fabrics, which then go to IVL Mullagh for processing, melting and extrusion to form polyester staple fiber. These staple fibers are then converted by TWE Group into nonwovens for use in Auping’s Evolve mattress, a fully circular mattress. Following the end of mattress use, the material recovery process simply starts again.

Auping estimates that annually more than 40 million mattresses are disposed of in Europe alone, the majority of which are incinerated. Their take back system in the Netherlands ensures that when their new mattress is delivered, the old mattress is retrieved and recycled, irrespective of the brand, ensuring existing materials are continually optimized, diverted from landfill and kept in use to achieve a circular economy.

Natural fibers are among the most important raw materials in the textile and fashion industry worldwide. For centuries, they have fed millions of people through their cultivation or breeding, and it is impossible to imagine daily life without them. Especially at the moment, natural fibers are gaining special importance due to the intense discussions about sustainable living. Even though natural fibers have accompanied mankind for a long time, they are changeable, technical, and adaptable to the challenges of the textile industry.

The Discover Natural Fibres Initiative (DNFI) is celebrating natural fibres in a program to be conducted during Heimtextil in Frankfurt on 23 June. Anyone with an interest in the role of natural fibres in the world economy, economic indicators of textile activity, innovations in natural fibre research, and updates on proposed EU legislation affecting textiles is welcome to attend.

The program will include various presentations by the previous and current award winners, presentations, and discussions:

Overview of world natural fibre production, employment, and value,

• Economic indicators and impacts of coronavirus on textile industries,
• Updates on innovative uses of natural fibres:
• Use of wool in automobile insulation applications for enhanced sustainability,
• Using cellulose from cotton to produce a biodegradable plastic substitute,
• Manufacturing waterproof fabric from a blend of cotton and jute as sustainable
• Substitute for polypropylene tarps
• Proposed EU textile legislation and potential impacts on natural fibres
