From the Sector

• New air purification and sulfur recovery plant up and running at the Lenzing facility
• Another step closer to meeting sustainability and climate targets
• Self-sufficiency in raw materials further enhanced

Lenzing Group is continuing to make great strides toward achieving carbon neutrality across the Group. The successful completion and commissioning of an air purification and sulfur recovery plant at the Lenzing facility marks another milestone in the Group’s ambitious strategy. Lenzing has invested some EUR 40 mn in this project since construction began in 2019.

Using state-of-the-art technology, the plant will enable carbon emissions to be reduced by 15,000 metric tons at the Lenzing facility. This will also make the group more self-sufficient in securing vital raw materials for processing, which will bolster the site’s competitive standing in terms of sustainability.

“As a result of this investment, Lenzing has made further progress towards implementing its climate targets, while achieving much greater autonomy with regard to one of its core raw materials”, says Christian Skilich, Member of the Managing Board at Lenzing Group.

In 2019, Lenzing set the strategic target of halving its group-wide greenhouse gas emissions per ton of product by 2030. Its goal for 2050 is to achieve climate neutrality.

Devan Chemicals recently added two more products to its range of bio-based textile finishes. One being a softener, the other one a quick-dry finish. Both are derived from vegetable oils and are in line with the company’s latest innovations on bio-based chemistry.

Due to the Covid-pandemic, serving as an accelerator for a worldwide green economy, the textile industry is increasingly seeking more sustainable and products fit-for-circular programs. According to McKinsey & Company, the textile industry will experience innovation surrounding sustainably sourced raw materials and bio-based chemical additives to accommodate increasing consumer demand.

Devan launched its first bio-based technology in 2019 and is fully committed to making bio-based versions of their existing textile finishes. ‘We have put ourselves on a mission to be able to extend our Bio-Based range further”, says Sven Ghyselinck, CEO of Devan. “We wanted to make an even bigger impact on circularity than before, therefore we looked into what fabric producers use a lot: softeners and moisture management systems. Only by focusing more on the large volume products, can we support the industry to have a bigger impact on sustainability. After the growing success of our natural antimicrobial BI-OME NTL, we are proud to now introduce our new natural Passerelle line”.

Passerelle Soft NTL is a durable softness technology based on vegetable ingredients. The technology is wash durable and can be used with natural fibres like hemp, cotton, but is also fit for synthetic fibres like rPES, PA. The bio content of the technology is above 85% (ASTM D6866-20).

Passerelle Quick-Dry NTL is a moisture management technology also based on vegetable ingredients. This bio-based finish enables high wicking and evaporation capability which helps to evaporate water/sweat easier and faster. The technology is also > 60% (28 days) biodegradable according to OECD 301B.

International technology Group ANDRITZ has always been at the forefront in providing innovative and sustainable solutions for the global nonwovens industry. Optimization of resource management, especially reducing the consumption of raw materials and other substances used and also keeping resources in use for as long as possible, are decisive factors in enabling nonwovens producers to offer competitive and sustainable products.

As a world market leader for nonwovens production equipment and services, ANDRITZ offers a full range of products to meet these challenging demands.

Maximizing the evenness of the product across the entire production line is one of the key success factors. The weight profiling product range of ANDRITZ – consisting of ProDynTM and ProWidTM – has been extended by ProWinTM. This new development is the combination of the two existing systems ProDynTM and ProWidTM. It allows nonwovens producers to achieve optimum weight profiling at the crosslapper delivery and increase their process speed by up to 15% at the same time. ProWin combines the long-term process experience and in-depth knowledge ANDRITZ has on needlepunch lines with innovative software to synchronize action across the line. Guillaume Julien, Head of Needlepunch Sales at ANDRITZ Nonwoven, explains,

“We have developed a self-regulating, advanced technology to reduce fiber deposits at the edges of the web and eliminate the “smile” effect across its width. ProWin enables producers to optimize the CV ratio autonomously and precisely while also generating significant fiber savings of up to 10% and increasing production speed. Thus, it also provides a faster ROI.“

When it comes to the spunlace process, a better product quality can be obtained by ensuring that the different equipment units in the production line are consistent with one another. The TT card, the Jetlace hydroentanglement unit, and the neXdry through-air dryer are the perfect combination to obtain premium visual quality and characteristics in the web. For an equivalent amount of fibers, this set-up is designed to produce an even web with significant bulkiness and an excellent MD:CD ratio without impacting the production capacity.

Maximizing performance by minimizing the raw material input and the amount of waste produced is a real driver of cost optimization. This is why ANDRITZ has created and integrated a solution that allows nonwovens producers to retrieve the wasted edges of their spunlace fabric and re-use it as recycled fibers. As a result, roll-good producers can even obtain the same web characteristics as when using virgin fibers, and most importantly, the exact same quality.

ANDRITZ also offers – under the brand Metris – ANDRITZ digital solutions – a variety of several service apps for optimum customer benefit. The Metris Cost Management app is used to track raw material consumption. It is an advanced system aimed at monitoring fiber consumption and allowing in-depth diagnoses to investigate raw material losses and savings grouped by different process areas. Thanks to this Metris application, ANDRITZ customers are able to optimize their system’s consumption of raw materials.

All these innovations are available in ANDRITZ’s technical centers, where ANDRITZ process experts will be glad to welcome customers in order to discuss and define their product expectations.

• Recycled polyester becomes a production standard for zips' tapes: a new step in Riri Group’s green path.
• Riri is the first company in the fashion accessories industry to complete its transition towards an exclusive use of recycled polyester for zips’ tapes.

To Riri, being ‘Responsible today for a sustainable tomorrow’ means looking ahead, toward a real effort in bringing sustainability in operational decisions, even if they mean more management issues and lead to changes out of the comfort zone which is the result of years of experiences and processes. Riri Group thus becomes the first manufacturing company in the fashion accessories industry to introduce the use of recycled polyester as production standard for its zip range. This achievement marks another essential one in the sustainability path that the Swiss-Italian Group has walked since the 90s. This change fits perfectly the Group’s green approach which sees innovation for the future as one of the main pillars of the corporate strategy, as well as the commitment to protecting natural resources and to improving the
traceability and transparency of both materials and processes, in a framework that sees to rethink social and economic models. Riri’s slogan “excellence in details” can also be read as “sustainability in details” as it speaks to the company’s will to act putting sustainability first.

By employing recycled polyester as production standard for the zip range, the contribution to sustainability on a quantitative level will be significant:

• The company, in fact, will reduce emissions resulting from polyester purchase by 32%; thus, carbon footprint will be cut down by 3%, for zip production. As a result, 460,000 kg of
CO2 per year is saved, the same as 169 return flights from Geneve to New York.

• All the recycled polyester is GRS (Global Recycled Standard)-certified, highlighting Riri’s constant commitment to choosing suppliers that meet the industry’s international standards.

• The recycled polyester used in tapes for zips is made from recycled polyester fibers, both  pre- (20%) and post-consumer (80%).

• An important contribution is made to the goal of increasing the global use of recycled polyester, as stated by Textile Exchange, from 14% to 20% by 2030.

This choice shows once more the ability of the company to develop products that keep in mind the environment whilst preserving functionality, reliability and that visual taste that the world of fashion requires.

Indeed, Riri has introduced its first recycled polyester tape in 2013 and since then has been consistently increasing the use of GRS-certified recycled polyester that comes from recycled materials.

“We are proud of this step and the effect that it has on sustainability and the cultural change through which we approach the development and improvement of our products” states Renato Usoni, Riri Group’s CEO. “Our innovation is the result of a tireless research of low environmental impact materials, an approach that has been the foundation of our identity for many years, but that now is renewed once more to make another step toward the future”.

After starting the first "Dibella up" circular-flow concept in August 2020, thousands of high-quality bags have already been made from used hotel textiles. Now the company is presenting another upcycling project: As part of a feasibility study, organic Fairtrade napkins that could no longer be rented out by the company were turned into jeans.

The second "Dibella up" project promises successful recycling of used object textiles. Within the framework of a feasibility study, almost 5,000 discarded napkins were used for jeans production in Pakistan. The special feature of the process is the traceability of the raw materials through all processing stages.

The napkins made of pure organic Fairtrade cotton originated in India. There, the fibres were grown and harvested by micro-farmers of the Chetna cooperative and then processed into durable textiles by a certified company. From Dibella, the napkins went to Lamme Textile Management, where they went through the use process in laundry and catering for many years. All stages were traceable by means of a "Respect Code" with which each piece was marked.

In the recycling project, the original supply chain was reversed: Dibella transported the organic Fairtrade napkins discarded by Lamme Textile Management to Pakistan. There, the goods were shredded and the organic Fairtrade cotton fibres recovered in a full-scale textile plant specialising in sustainability. In the next step, they were mixed with "fresh fibres", spun into yarns for denim production, woven, finished with sustainable processes, subjected to quality tests and then made up into jeans.

• 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.

• Major Monforts denim customers continue to pioneer new initiatives that are pushing the boundaries of sustainable production.

Recycling their cotton waste has become one way these companies can do more with less, and at the recent Kingpins24 Flash online event, Sedef Uncu Aki, director of Orta, headquartered in Istanbul, Turkey, announced a new partnership with leading recycling operation Gama Recycle.

Traceable
“Through this local partnership we will supply the waste from our spinning mills and return around 3,000 tons of premium quality cotton back to them,” she said. “We have established a truly controlled and traceable system and partnering with a domestic recycling centre is important because a lot the carbon emissions associated with recycling usually come from transportation.”

Orta’s ZeroMax range meanwhile uses no cotton at all, being based on Lenzing’s Tencel cellulosic fibre, while the company’s involvement in denim production for a recent launch by Levi Strauss, of jeans made with organic cotton and Circulose – a breakthrough material developed by re:newcell of Sweden and partners – was hailed as a further step forward.

To make Circulose, re:newcell repurposes discarded cotton textiles, such as worn-out denim jeans, through a process akin to recycling paper. The incoming waste fabrics are broken down using water. The colour is then stripped from these materials using an eco-friendly bleach and after any synthetic fibres are removed from the mix, the slurry-like mixture is dried and the excess water is extracted, leaving behind a sheet of Circulose. This sheet is then made into viscose fibre which is combined with cotton and woven into new fabrics.

Circular Park
Omer Ahmed, CEO of Artistic Milliners also announced plans for his company’s new 70,000 square-foot Circular Park in Karachi, Pakistan, at Kingpins24 Flash.

Once complete, this will add three million square metres of additional denim capacity a month to the company’s production and take its total recycled output to a monthly five million metres.
Ahmed observed that there is currently a lack of sustainable fibres that are readily available to use for denim production at scale.

“Organic cotton is too expensive, and in my opinion always will be,” he said. “Cottonised hemp is also not cheap and it’s hard to mix with cotton, while the new regenerated cellulose fibres that are now emerging are promising, but currently in short supply. Recycled polyester is meanwhile still based on petroleum resources which we want to move away from. As a consequence, there are only a few other options for us as a manufacturer and this new project will help us minimise our own waste while significantly lowering our carbon footprint.”

Other Monforts denim customers to introduce cotton fibre recycling operations at their plants recently include AGI Denim, Bossa and Soorty.

Vertical savings
Refresh is the name of the latest collection from AGI Denim – reflecting the company’s significant reduction in water consumption.

The company has just opened new fibre spinning and denim mills at its complex in Karachi, Pakistan.

“Over the years we’ve gone through a series of backward integration steps to become fully vertical,” said AGI Denim executive director Ahmed Javed, at Kingpins24 Flash. “In our latest expansion, we revisited every step of the production processes in order to make resource savings.”

Innovations have included the installation of proprietary robotics for garment finishing, but the most attention has been paid to water savings.

“Pakistan is one of the largest cotton-producing companies in the world and we’re fortunate that the type of cotton that is grown here is well suited to denim production and also helps us lower our carbon footprint, with everything done in close proximity,” Javed said. “In the lifecycle of a pair of denim jeans, however, cotton fibre production contributes 68% of water consumption. While we cannot control how much water cotton needs for it to grow, we can rethink the way we use it in our factory.”

Refresh-branded denims are washed from 100% recycled water as a result of the company’s new wastewater treatment plant, which puts production wastewater through a series of steps beginning with equalisation, followed by aeration and concluding with sedimentation. The water travels through filtration and ultrafiltration systems before being subjected to an activated carbon system and finally a reverse osmosis system to reduce any dissolved salts.

AGI now recycles 4.4 million gallons of water each month – enough to wash a million pairs of jeans.

Sustainable
Monforts has a leading position in the field of denim finishing with its well proven Thermex continuous dyeing systems, Montex stenter dryers and other lines for resource-efficient and economical processing.

“Our denim partners are constantly setting themselves new goals in respect of sustainable production – and more importantly, achieving them,” says Hans Wroblowski, Monforts Head of Denim. “We work closely with them with the aim of constantly optimising processing parameters and achieving further savings in energy, water and raw materials throughout the dyeing and finishing stages of production.”

The latest Monforts innovation for denim is the CYD yarn dyeing system. This technology is based on the effective and established dyeing process for denim fabrics that is now being applied for yarn dyeing. The CYD system integrates new functions and processes into the weaving preparation processes to increase quality, flexibility, economic viability and productivity. A full CYD line is now available for trials at the company’s Advanced Technology Centre in Mönchengladbach, Germany.”

• AFRY engineering partner when Renewcell expands operations to lead the fashion industry into a sustainable and circular future

Renewcell has awarded AFRY an engineering assignment for their recycled textile materials production expansion at SCA's Ortviken paper mill in Sundsvall, Sweden. The assignment includes project and construction management services, process, mechanical and piping engineering, electrical, automation and instrumentation engineering, fire and HVAC design, as well as civil design. The project is a continuation of AFRY's previous feasibility studies.

The trend in textiles and design requires sustainable fashion. Customers require fashion companies to reduce their environmental impact through new technologies and innovations for the circular economy. One important element is recycling of textile fibers that is a path towards a more sustainable fashion.

Renewcell is a multi-award-winning textile recycling company based in Sweden. The company’s vision is to inspire an Industrial Evolution towards a sustainable world by producing high quality materials from recycled textiles. “There is a way to put fashion first without putting the environment in second place” – Renewcell describes their business concept. With their technology, the company has succeeded in recycling and regenerating textile fiber from old clothes to turn into new clothes. For example, H&M, a partner of Renewcell, has launched a garment that is half made with Renewcell’s fabric.

Today, Renewcell has a demo plant in Kristinehamn, Sweden, with the possibility to recycle over 4,500 tons of textiles each year. The company has now signed a major agreement with one of the world's largest producers of viscose fiber. With that as a basis, together with a well-proven process and technology, they are now building a full-scale production plant in Sundsvall, Sweden. When the new plant is ready for production, it will have the capacity to recycle 60,000 tons of textile waste annually, which is just over half of Sweden's annual textile consumption. The new plant is expected to be commissioned in 2022.

“We are pleased to continue the partnership with AFRY, which began with the feasibility study they delivered in 2020. With AFRY, we feel secure in having a partner with both world-leading expertise and the ability to deliver projects on time and within budget. Together, we lead the fashion industry into a sustainable and circular future,” says Christer Johansson, Project Director at Renewcell.

“We are extremely proud to be part of Renewcell’s investment. We are excited to contribute in this transition towards more sustainable solutions for the future and look forward to continue this journey together with Renewcell,” says Ulf Strenger, Business Unit Manager at AFRY.
