• 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.

• Achievement Ahead of Schedule

All of Sateri’s five viscose mills in China are now fully compliant with the emission limits set out in the European Union Best Available Techniques Reference Document (EU-BAT BREF) on Polymers, following recent verification of Sateri Jiangsu and Sateri China mills.

Verified by independent consultant Sustainable Textile Solutions (STS), a division of BluWin Limited (UK), the parameters assessed included resource utility efficiency, wastewater discharge and air emission.

Allen Zhang, President of Sateri said, “Sateri Jiangsu was established in 2019 following an acquisition while Sateri China was built in the same year. We had aimed to have both mills meet EU-BAT’s recommended emission levels by 2023. To achieve this two years ahead of schedule underscores our continuous efforts in process improvement and control of pollutant emissions, and resource utilization efficiency. We will continue to pursue manufacturing excellence and invest in best-in-class technologies for all our mills – existing, acquired, and newly constructed ones – as part of our Vision 2030 commitment towards closed-loop and cleaner production.”

Chen Xinwei, Chairman of China Chemical Fiber Industry Association, said, "China's regenerated cellulose fibre industry has been progressing steadily in recent years. As a major viscose manufacturer, Sateri has demonstrated leadership in benchmarking itself against advanced domestic and international standards, focusing on low-carbon development, energy-saving and emission-reduction technology, and cleaner production to advance sustainable development, as well as enhance the company’s competitiveness. All other players in the industry should be encouraged to follow suit."

Sateri is a member of the RGE group of companies; Sateri’s other three mills - Sateri Fujian, Sateri Jiujiang and Sateri China (Jiangxi) - had attained EU-BAT compliance in 2020.

After a long break, the international nonwovens industry will meet again in Geneva, Switzerland, from October 19 to 22, 2021 on the occasion of INDEX. DiloGroup offers tailormade production systems from one supplier and will inform about its portfolio and the latest equipment developments from fibre opening to the finished felt.

A new, simplified elliptical needle beam drive makes Hyperpunch technology also attractive for standard application. Hyperpunch HαV allows a more uniform stitch distribution in the preneedling process especially in combination with the new needle pattern 6000X. In a complete needling line this felt homogenization process can be improved further by using the new needle pattern 8000X which is a milestone in the needle pattern development process and results in endproduct surfaces with low markings over a wide range of advances/stroke.

The “3D-Lofter” which was first presented during ITMA 2019 in Barcelona offers a wider range of nonwovens applications by exploring the third dimension. A series of single web forming units which work according to the aerodynamic web forming principle deliver defined fibre masses in varied patterns on a base needlefelt. A stress oriented production of technical formed parts resulting in fibre savings or patterned DI-LOUR or DI-LOOP felts are two examples for this technology which explores new application areas for needlefelts The 3D-Lofter technology may also be used “inverted” for filling up bad spots in web mats and thus achieves a better homogeneity of e. g. spunlace, thermobond or airlay products.

The DiloLine 4.0 concept offer I4.0 modules which not only support the user but also facilitate quality control and maintenance by a maximum data transparency in production and control of operation. The Dilo solutions “Smart Start” for a fully automatic start of the production line or “DI-LOWATT” for energy savings are accompanied by Siemens solutions which can be selected via App or Data Cloud “MindSphere”.

Apart from machines for needling technology we offer in cooperation with partner companies also production lines including thermobonding and hydroentangling components.

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.

Materials science innovation pioneer Hologenix, LLC, whose CELLIANT® infrared technology is an ingredient in brands across many categories, has another important partner, bedding specialist Centa-Star. Based in Stuttgart, Germany and available throughout Europe, Centa-Star has introduced a new line of “Regeneration” duvets and pillows infused with CELLIANT mineralized fibers.  

Regeneration products, thanks to CELLIANT, are thermo-regulating with maximum breathability, promoting stronger performance, faster recovery and better sleep.

CELLIANT thermo-reactive minerals absorb the body heat and convert it into infrared energy, which is reflected back to the body.  The resulting temporary increase in blood flow and local circulation helps regulate body temperature and increases tissue oxygen. This leads to a more restful, restorative sleep as well as faster recovery and stronger performance.

Centa-Star Regeneration products are available online throughout Europe in selected department stores in Germany, Austria and Switzerland, including KaDeWe Berlin, Betten Rid in Munich, Karstadt or Kaufhof stores, in well-sorted furniture shops, in upscale specialist shops.

To ensure product protection and prevent brand piracy, GRAFE has developed a simple and elegant solution that also offers a high level of security. The basis is special markers. "The highly complex pigments with special physical properties designed for this purpose are used in minute quantities within the plastic matrix. With an appropriately calibrated detector, products equipped with them can thus be read and authenticated," explains Business Development Manager Florian Ludwig. At the same time no changes in properties can usually be observed. The detectors can use an LED display to check within seconds whether the unique marker is contained in the product and whether this item is the original product.

In general, there are two options: x ray and light fluorescence, i.e. fluorescent X-rays or light. With the first option, the base color has no influence (not even black) and the customer benefits from low addition dosage and batch price, but this method requires higher investment. "With light fluorescence, on the other hand, detection is done by a measuring device, which is preconfigured by our partner or by us directly. Different types are available, from handy hand-held measuring devices to stationary office solutions to inline spectrometers, in order to have a control take place directly during production," Ludwig explains. With this method, the masterbatch dosage is based on the base color, among otherv things. The method of operation is fast and simple, and the necessary investment is also manageable.

From injection molding and extrusion to transparent and fiber applications, almost all areas of plastics processing come into question.

• Long-term partnership between the Austrian textile producer FEINJERSEY and the German textile machinery manufacturer BRÜCKNER

The Feinjersey Group is an internationally operating textile company and supplies the "global players" of the textile industry worldwide. The value chain of the company, which is based in Götzis, Austria, ranges from yarn processing to the finished product.

As a fully integrated production company, the internationally active textile company Feinjersey attaches great importance to a high quality standard and guarantees care at every step in the process chain. With approx. 250 employees and annual sales of around 45 million euros, the company knits, dyes and finishes top-quality knitted fabrics as well as elastic woven fabrics for a wide range of applications.

Products are made for the fashion, sports, workwear and technical textiles sectors. Among other things, fabrics for the automotive industry, laminating backings and coating substrate for artificial leather or foils, construction textiles or fabrics for medical technology are all produced.

The Austrian textile manufacturer has been certified with the Bluesign textile seal and ensures efficient use of resources with modern machinery. Water and energy consumption as well as pollutant emissions are to be reduced to a minimum.

In textile finishing in particular, the focus is on minimising energy consumption as this process is the most energy-intensive in the entire process chain. Feinjersey uses its own photovoltaic system for this purpose, as well as the heat recovery and exhaust air purification systems on the stenter frames. By using the waste heat from production, the company's buildings are heated. All six stenter frames at Feinjersey are made by BRÜCKNER and produce with three-stage heat recovery and exhaust air purification systems.

The latest BRÜCKNER line has a working width of 4.20 m and is mainly used for the finishing of high-ly elastic and extremely sensitive knitted fabric. In order to avoid yellowing on the fabric, the stenter is equipped with an indirect gas heating system. The knitting oil vapours coming from the fabric during the heat-setting process are extracted from the dryer and cleaned in a BRÜCK-NER ECO-AIR exhaust air cleaning system before being extracted to atmosphere. The complete exhaust air treat-ment on the newest stenter is carried out by a multistage BRÜCKNER ECO-HEAT and ECO-AIR system.

• Renewably Sourced Materials to Help Replace Petrochemicals in Apparel for a Healthier Planet

lululemon athletica inc. (NASDAQ:LULU) announced a multi-year collaboration with sustainable materials leader Genomatica to bring renewably-sourced, bio-based materials into lululemon’s products. This represents lululemon’s first-ever equity investment in a sustainable materials company and Genomatica’s largest partnership within the retail industry. Together, the two companies will create a lower-impact, plant-based nylon to replace conventional nylon, which is the largest volume of synthetic material currently used to make lululemon products.

Genomatica uses biotechnology and fermentation to convert plant-based ingredients into widely used chemical building blocks, like those used to make nylon. These building blocks are converted to pellets and yarns, and the companies will be working closely with lululemon’s fabric supply chain to incorporate this material into future products. Through this collaboration, the companies seek to create positive change within the $22B global nylon market by building more sustainable supply chains.
