• From fossil to renewable materials: Members advocate policy analysis and focused implementation of the renewable carbon strategy

The members of the Renewable Carbon Initiative (RCI) (www.renewable-carbon-initiative.com), founded in September 2020, have joined forces to shape the transition from the fossil to the renewable age for the chemical and materials industry. This means spreading the concept of renewable carbon and developing new value chains based on renewable carbon as a feedstock.

In the meantime, several activities have started from which future members can benefit as well. First and foremost is the kick-off to comprehensive policy analysis. What influence will forthcoming regulation have on chemicals, plastics, and other materials? When and where should the renewable carbon idea be emphasized and referred to?

The policy analysis will examine pending policies in the European Union – and a later expansion to America and Asia is planned as well.

A particular focus will be placed on upcoming policies and regulations and how they impact renewable carbon. The members are currently deciding on where to start specifically, but questions that may be considered are: What does the new climate law and the “Fit for 55-Package” mean for chemicals and materials? What can be expected from REACH and microplastics restrictions? How relevant is the “Sustainable Products Initiative” and the coming restrictions for Green Claims? Circular Economy, Zero Pollution and Sustainable Financing are keywords of the future European landscapes, which might become very concrete for chemistry and materials in the next few years. To what extent the concept of renewable carbon for materials is considered in policy already and how it could be further introduced in future legislation are two of the main questions investigated in the working group “Policy”.

This working group is open to all members of RCI. Policy experts provide the respective analysis as a foundation, organising discussions between members of the policy group and plan meetings with policymakers to introduce the Renewable Carbon concept.

Additional working groups have been created, one with a focus on communication, the other looking at the development of a renewable carbon label. In early September, a renewable carbon community will be launched as a starting point for even more interaction between the members, to discuss strategies, create new value chains and start project consortia.

The Renewable Carbon Initiative (RCI) is a dynamic and ambitious group of interested parties. Membership numbers have now more than doubled since the launch almost a year ago, with RCI now boasting 25 members, 6 partners and over 200 supporters. It welcomes all companies that are on the way to transform their resource base from fossil to renewable.

Iluna Group comes back to Milano Unica with a great and important goal: to relaunch the qualities and dimensions of sustainability by going beyond the ingredient.

Iluna’s new path, which was born in a moment when the market seems to speak about “fragility”, begins with the investment in the renewal of machines, which allow it to fly ever higher in terms of high-tech developments, quality, definition, effects of yarns and patterns. The journey into the new dimension of responsible quality continues with ad hoc developments in the field of GRS (Global Recycled Standard) certified recycled yarns, aimed at unprecedented effects both in look, in performance and in the hands of fabrics. Including cord yarn, shiny threads and an expansion of the range of GRS yarns, previously available only opaque. The cord yarn is a precious yarn with a ROICA™ EF premium stretch yarn core, GRS certified and developed with 50% of pre-consumer waste materials content - double, covered with an equally recycled shiny thread; the bright and translucent is instead to add brilliant effects so far not possible with a GRS yarn.

The printing processes are also born from this constant search for innovation towards new materials and new techniques, becoming more and more sustainable: Global Recycle Standard (GRS)-certified sublimation printing and register printing carrying Global Organic Textile Standard (GOTS) certification. This one overlap exactly on the design and color the details, reaching where the dye cannot reach.

Diversification has become essential in today’s competitive market and the fragility of the moments experienced in 2020 was the stimulus to return to being here again, to return to action. Flexibility is the watchword today, along with research. And Iluna has managed to go further: starting from the ingredients at the base of the materials, last year launched a collection with natural dyes made with GOTS certified plant-based dyes, up to proposing magnificent prints with extraordinary effects for this edition of the Milanese fair.

The three dimensions of sustainability, design and innovation are thus finally linked thanks to valuable partnerships with expert and excellent reference companies that have allowed these new developments and these unique results thanks to advanced technologies designed specifically for Iluna, which is today the only company to offer ingredients, natural colors and prints, all three strictly certified.

• Fraunhofer, SABIC, and Procter & Gamble join forces
• The Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE and its Institute for Environmental, Safety and Energy Technology UMSICHT have developed an advanced recycling process for used plastics.
• The pilot project with SABIC and Procter & Gamble serves to demonstrate the feasibility of closed-loop recycling for single-use facemasks.

Due to COVID-19, use of billions of disposable facemasks is raising environmental concerns especially when they are thoughtlessly discarded in public spaces, including - parks, open-air venues and beaches. Apart from the challenge of dealing with such huge volumes of essential personal healthcare items in a sustainable way, simply throwing the used masks away for disposal on landfill sites or in incineration plants represents a loss of valuable feedstock for new material.

“Recognizing the challenge, we set out to explore how used facemasks could potentially be returned into the value chain of new facemask production”, says Dr. Peter Dziezok, Director R&D Open Innovation at P&G. “But creating a true circular solution from both a sustainable and an economically feasible perspective takes partners. Therefore, we teamed up with Fraunhofer CCPE and Fraunhofer UMSICHT’s expert scientists and SABIC’s Technology & Innovation specialists to investigate potential solutions.”

As part of the pilot, P&G collected used facemasks worn by employees or given to visitors at its manufacturing and research sites in Germany. Although those masks are always disposed of responsibly, there was no ideal route in place to recycle them efficiently. To help demonstrate a potential step change in this scenario, special collection bins were set up, and the collected used masks were sent to Fraunhofer for further processing in a dedicated research pyrolysis plant.

“A single-use medical product such as a face mask has high hygiene requirements, both in terms of disposal and production. Mechanical recycling, would have not done the job”, explains Dr. Alexander Hofmann, Head of Department Recycling Management at Fraunhofer UMSICHT. “In our solution, therefore, the masks were first automatically shredded and then thermochemically converted to pyrolysis oil. Pyrolysis breaks the plastic down into molecular fragments under pressure and heat, which will also destroy any residual pollutants or pathogens, such as the Coronavirus. In this way it is possible to produce feedstock for new plastics in virgin quality that can also meet the requirements for medical products”, adds Hofmann, who is also Head of Research Department “Advanced Recycling” at Fraunhofer CCPE.

The pyrolysis oil was then sent to SABIC to be used as feedstock for the production of new PP resin. The resins were produced using the widely recognized principle of mass balance to combine the alternative feedstock with fossil-based feedstock in the production process. Mass balance is considered a crucial bridge between today’s large scale linear economy and the more sustainable circular economy of the future, which today is operated on a smaller scale but is expected to grow quickly.

“The high-quality circular PP polymer obtained in this pilot clearly demonstrates that closed-loop recycling is achievable through active collaboration of players from across the value chain”, emphasizes Mark Vester, Global Circular Economy Leader at SABIC. “The circular material is part of our TRUCIRCLE™ portfolio, aimed at preventing valuable used plastic from becoming waste and at mitigating the depletion of fossil resources.”

Finally, to close the loop, the PP polymer was supplied to P&G, where it was processed into non-woven fibers material. “This pilot project has helped us to assess if the close loop approach could work for hygienic and medical grade plastics”, says Hansjörg Reick, P&G Senior Director Open Innovation. “Of course, further work is needed but the results so far have been very encouraging.”

The entire closed loop pilot project from facemask collection to production was developed and implemented within seven months. The transferability of advanced recycling to other feedstocks and chemical products is being further researched at Fraunhofer CCPE.

• Swiss weaving machinery manufacturers are in the forefront of novel application development

Shoes and electronic calculators are probably not the first products people would associate with the textile weaving process. But they certainly signpost the future for woven fabrics, as two examples of the ever-wider possibilities of latest technology in the field. Fashion and function already combine in the increasing popularity of woven fabrics for shoes, and this is a present and future trend. Calculators in fabrics? That’s another story of ingenious development, using so-called ‘meander fields’ on the back and keys printed on the front of the material.

These glimpses of the outlook for modern weavers are among the highlights of developments now being pioneered by Swiss textile machinery companies. All weaving markets require innovation, as well as speed, efficiency, quality and sustainability. Member firms of the Swiss Textile Machinery Association respond to these needs at every point in the process – from tightening the first thread in the warp to winding the last inch for fabric delivery. They also share a common advantage, with a leading position in the traditional weaving industry as well as the expertise to foster new and exciting applications.

Technology and research cooperation
The concept of a ‘textile calculator’ was developed by Jakob Müller Group, in cooperation with the textile research institute Thuringen-Vogtland. Müller’s patented MDW® multi-directional weaving technology is able to create the meander fields which allow calculator functions to be accessed at a touch. A novel and useful facility, which suggests limitless expansion.

Today, the latest woven shoes are appreciated for their precise and comfortable fit. They score through their durability, strength and stability, meeting the requirements of individual athletes across many sports, as well as leisurewear. Stäubli is well known as a leading global specialist in weaving preparation, shedding systems and high-speed textile machinery. Its jacquard machines offer great flexibility across a wide range of formats, weaving all types of technical textiles, lightweight reinforcement fabrics – and shoes.

It’s possible to weave new materials such as ceramics, mix fibers such as aramid, carbon and other, and produce innovative multi-layers with variable thicknesses. Such applications put special demands on weaving machines which are fulfilled by Stäubli high-performance TF weaving systems.

Great weaving results are impossible without perfect warp tension, now available thanks to the world-leading electronic warp feeding systems of Crealet. Some market segments in weaving industry today demand warp let-off systems which meet individual customer requirements. For example, the company has recognized expertise to understand that geotextile products often need special treatment, as provided by its intelligent warp tension control system. Individual and connective solutions are designed to allow external support via remote link. Crealet’s warp let-off systems are widely used in both ribbon and broadloom weaving, for technical textiles applied on single or multiple warp beams and creels.

Functional, sustainable, automated
Trends in the field of woven narrow fabrics are clearly focused on functionality and sustainability. The Jakob Müller Group has already embraced these principles – for example using natural fibers for 100% recyclable labels with a soft-feel selvedge. It also focuses as much as possible on the processing of recycled, synthetic materials. Both PET bottles and polyester waste from production are recycled and processed into elastic and rigid tapes for the apparel industry.

For efficient fabric production environments, it is now recognized that automated quality solutions are essential. Quality standards are increasing everywhere and zero-defect levels are mandatory for sensitive applications such as airbags and protective apparel.

Uster’s latest generation of on-loom monitoring and inspection systems offers real operational improvements for weavers. The fabric quality monitoring prevents waste, while the quality assurance system significantly improves first-quality yield for all applications. Protecting fabric makers from costly claims and damaged reputations, automated fabric inspection also removes the need for slow, costly and unreliable manual inspection, freeing operators to focus on higher-skilled jobs.

Smart and collaborative robotics (cobots) offer many automation possibilities in weaving rooms. Stäubli’s future oriented robotics division is a driver in this segment with first effective installations in warp and creel preparation.

Control and productivity
Willy Grob’s specialized solutions for woven fabric winding focus on reliable control of tension, keeping it constant from the start of the process right through to the full cloth roll. Continuous digital control is especially important for sensitive fabrics, while performance and productivity are also critical advantages. In this regard, the company’s large-scale batching units can provide ten times the winding capacity of a regular winder integrated in the weaving machine.

The customized concept by Grob as well as design and implementation result in great flexibility and functionality of the fabric winding equipment – yet another example of Swiss ingenuity in textile machinery.  
There is even more innovation to come in weaving – and in other segments – from members of the Swiss Textile Machinery Association in future! This confident assertion is founded on an impressive statistic: the 4077 years of experience behind the creative power of the association’s member firms. It’s proof positive that their developments grow out of profound knowledge and continuous research.

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, today announced the launch of ‘Pad-Ox G2 Cold’, a water-saving dyeing process at room temperature for casual looks.

Archroma initially introduced its eco-advanced Pad-Ox dyeing process for woven fabrics, and then used it as part of its ADVANCED DENIM concept. By combining the oxidation and fixation steps, it is possible to shorten the dyeing process and thus realize substantial resource savings in water, wastewater, cotton waste, and energy.

Over the years the company has worked with its textile manufacturers and partners to improve the Pad-Ox process, in particular woven applications such as chinos and casual wear. To achieve maximum positive impact, Archroma is using its Diresul® range of low sulfide sulfur dyes and, more recently, its innovative plant-based range of EarthColors®. A wide selection of dyes from these two ranges have received the Cradle-to-Cradle Product Innovation Institute’s Platinum Level Material Health Certification.

Meanwhile, Jeanologia has been working on the technology side, with laser and eco-finishing solutions for more than 25 years, accompanying the textile industry on their way to producing with zero discharge. In 2008, the company introduced its G2 Dynamic the first ozone treatment for continuous fabric that dramatically reduces the amount of water and chemicals used, while at the same time saving costs at the mill and eventually at the garment finishing facilities. This technology makes fabric more stable and consistent and prepares the fabric better for the use of other technologies like laser. This machinery can be used along with Pad-Ox technology to help cleaning fabric thus improve fastness results. While it allows process to work at room temperature.

Project focus on water saving
Archroma and Jeanologia therefore understandably decided to team up and combine their expertise in sustainable dyeing and finishing technologies. The objective of the project was to improve the Pad-Ox dyeing process even further, in particular in one area that still offered room for positive impact: temperature and fastnesses.

The new ‘Pad-Ox G2 Cold’ dyeing process works thanks to the insertion of very small machinery into the existing finishing range process, using cold processing and thus operating with much less water, carbon footprint and energy than traditional benchmark fabric finishing processes, whilst retaining the water and other resource savings offered by the Pad-Ox technology.

Maximum savings can be achieved by mills and garment manufacturers who wish to switch from a conventional dyeing process straight to ‘Pad -Ox G2 Cold’ to obtain high quality fabrics for comfortable and casual wear.
