From the Sector

Belgian textile innovator Devan Chemicals was lauded by Frost & Sullivan for its antimicrobial technology with proven quaternized silane chemistry, known under its trade name as BI-OME®.

RONSE, BELGIUM – The non-leaching attributes of the technology coupled with its ability to reduce microbial mutation make it a potential candidate for textiles where durability and safe human contact are highly valued.

Based on its recent analysis of the European antimicrobial technology for the textile market, Frost & Sullivan recognizes the Belgium-headquartered Devan Chemicals NV (Devan) with the 2020 European Technology Innovation Leadership Award. Devan’s highly relevant antimicrobial technology addresses issues concerning the contamination of PPE and textiles, including the spread of drug-resistant bacteria, viral transmissions, and hospital-acquired infections (HAIs). Its quat-silane technology, due to its non-migrating behaviour, physically punctures the microorganism cell to destroy it without interfering with cell DNA. Notably, it eliminates the adverse effects of leaching antimicrobials while providing high efficiency in the range of 99.9 percent to 99.99 percent, even after multiple washes.

"By providing non-migrating antimicrobial technology for the textile industry, Devan plugs the safety and performance gaps inherent in current inorganic and organic antimicrobial agents. Its antimicrobial technology, unlike silver- or triclosan-based technology, comprises non-migrating monomers and prepolymers such as organo-functional silane," said Monami Dey, Industry Manager, Frost & Sullivan. "The organo-silane polymers are covalently bonded and polymerized to the textile surface as a coating via padding, exhaust, and spraying techniques. The coating forms a non-leaching reactive surface and destroys the microbes on contact, without releasing harmful components into the environment."

Devan CEO Sven Ghyselinck is very happy with the award: “The best practice award is a nice recognition of the hard work we did in the last 6 months to evaluate the performance against viral activity. It’s great to see our efforts didn’t go unnoticed.”

Earlier this month Devan published new test results confirming the high performance virus-reducing capabilities of its BI-OME fabric coating technology on both unwashed and intensely washed fabrics. The Belgian company has worked closely with a series of international third party laboratories to test different fabric substrates against a wide range of enveloped viruses. Before washing, samples treated with Devan BI-OME score very good to excellent (99% and higher according to ISO 18184) results on virus reduction. Different substrates, like polyester, cotton and polycottons, were exposed to enveloped viruses like SARS-COV-2 (known to cause COVID-19), Feline Corona, Vaccinia (the EU standard for enveloped viruses) and Porcine Respiratory viruses. After 30minutes, BI-OME already reduced 99.96% of the activity of SARS-COV-2.

After washing, a decrease in virus reduction performance of coating technologies is normal and expected. However, BI-OME is confirmed to deliver only a minimal reduction, retaining up to 98.5% virus reduction even when the fabric is washed 25 times.

"Devan is working towards sustainability and green chemistry. For instance, its technology does not contain any harmful solvents such as formaldehyde or polychlorinated phenols and fulfills the regulatory obligations of the EU BPR," noted Dey. "Its commitment to promoting sustainability in textile finishes with a strong focus on GMO-free, kosher, as well as halal certifications, and recyclability has given the company an edge in launching new products at an accelerated pace to match customers’ most pressing concerns and demands."

One of those innovations is BI-OME NTL (natural), a natural, bio-based antimicrobial solution that guarantees an optimal freshness and hygiene for textiles. The active ingredient is the well-known Linseed oil, obtained from the dried, ripened seeds of the flax plant. The active ingredients in BI-OME NTL are GMO free, Halal, Kosher and recyclable.

Following the successful commissioning of two new Monforts Montex wide-width stenter lines and additional environmental management equipment at its plant in Germany, GtA – Society for Textile Equipment GmbH – is aiming to be the first textile finishing company to become entirely CO2-neutral in the manufacture of all of its products by 2025.

GtA is a partner company to Germany’s large-format digital printing fabric leader, Georg and Otto Friedrich GmbH, which has has this year been able to considerably expand its portfolio due to the new Monforts lines.

Headquartered in Gross-Zimmern, close to Frankfurt, Georg and Otto Friedrich GmbH and its partners in Germany have an annual production of 37 million square metres of warp knits for a range of end-use applications, including garments, automotive interiors and technical textiles, but increasingly with a concentration on digital printing substrates.

Fault-free textiles

A new standard in pure white, 100% clean and fault-free textile substrates has been demanded by this market in recent years due to the rapid growth in digitally-printed banners and billboards – often referred to as ‘soft signage’.

The substrates of choice for digital printing are 100% polyester warp knits which are resilient and allow excellent take-up of inks, and vibrant colours and clear and precise images to be achieved with digital printing techniques. The knitted construction also has the advantage of elasticity, which is a plus in terms of flexibility for installers.

Critically, the warp knitted fabrics have extremely smooth surfaces which is becoming increasingly important due to the general move away from PVC coatings which were the standard in the past.

It was to finish these fabrics for Georg and Otto Friedrich GmbH as well as providing such services for many other customers, that the GtA plant in Neresheim, Baden-Württemberg, was established in 2015.

The purpose-built plant on a greenfield site was initially equipped with a fully-automated, 72 metre long Monforts installation comprising a washing machine integrated with a 3.6 metre wide, seven-chamber Montex stenter. The line quickly went from single to double shift production and then to 24/7 operation  to meet demand.

Expanded widths

Building on the success of this installation, GtA has now installed two more Montex stenter lines – both in expanded working widths of 5.6 metres and purpose-built at Montex GmbH in Austria.

A six-chamber Montex unit is combined with a washing machine to guarantee the purity of the substrates, while a five-chamber line is integrated with a wide-width coating machine. This new coating capability at GtA has led to a number of new additions to the Georg and Otto Friedrich DecoTex range for digital printing, including wide width fabrics with flame retardant, antimicrobial and non-slip finishes.

The new Montex stenter lines benefit from all of the latest innovations from Monforts, including the Smart Sensor system for the optimised maintenance planning of key mechanical wear components on the stenters. A comprehensive overview of the condition of all parts at any time is now available for operators within the highly intuitive Qualitex visualization software.

With Qualitex, all article-specific settings can be stored and the formulations for thousands of treatment processes called up again at any time. Individual operators can also personalise their dashboards with the most important machine functions and process parameters.

Environmental commitment

GtA is run by a seasoned team of textile professionals led by Managing Director Andreas Niess.

“We have received excellent service from Monforts from the outset and we were happy to place the order for these two new lines as part of our ongoing cooperation,” he says. “With all of the latest Monforts advances in technology we are fully in control of all production and quality parameters with these lines, as part of our significant commitment to innovative environmental technology.”

The GtA plant, which operates in near-cleanroom conditions, has also been equipped with proprietary technology to fully exploit the Monforts air-to-air heat recovery systems that are now standard with Montex stenters.

“Around 30 per cent of our investment volume at the site goes to energy-saving measures and we are sure that this commitment is worthwhile,” Mr Niess says. “As an example, our integrated heat recovery system fully exploits the waste heat from the process exhaust air and the burner exhaust gases of the Monforts stenters, allowing us to achieve an exhaust air temperature of  between 30 to 34°C, compared to what would conventionally be between 140 to 160°C. Another focus has been on exhaust air purification technology and here too, the latest technology has been installed with integrated heat recovery elements.”

This, he adds, saves 52% of the energy that would normally be used – equating to 5,800,000 KwH per year. The necessary audits for energy-efficient companies are also carried out annually.

In addition, GtA has purpose-designed the automatic chemical mixing and dosing systems that feed the padders for the key treatments that are carried out on the fabrics through the stenters.

The company is going further, however, in its pursuit of clean production and raw materials.

"We want to be an asset and not a burden on our immediate environment and therefore do not use any additives containing solvents," Mr Niess says. “We were the first to use fully halogen-free flame retardant chemistry, and we use bio-based, finely ground alumina products for the washing process instead of surfactants. PES polyester yarns made from recycled material are also increasingly used and the latest additions to our raw materials portfolio, the RC-Ocean products, are made from recycled sea plastic.

“We are now planning a combined heat and power plant for the production of electrical energy and heat and we will also build a photovoltaic system that converts solar radiation into electrical energy. GtA wants to be the first textile finishing company to be CO2-neutral in the manufacture of all of its products by 2025. The complete heat supply and heating for the 13,000 square metre production hall, as well as the office building and the hot water supply for the domestic water, is already energy-neutral. We are convinced that this commitment will pay off in the long term and our positive business development proves that sustainability and business profitability are perfectly compatible.”

In addition to the products for Georg and Otto Friedrich GmbH, GtA  offers its manufacturing capacities for other customers as a contract service.

All products are manufactured in accordance with Öko-Tex Standard 100, product class 1 and the company is also involved in the research and development of new sustainable manufacturing processes, in cooperation with many regional universities and funding project partners.

Starting midth of July, brands and retailers can join the U.S. Cotton Trust Protocol, a new system for responsibly grown cotton that will provide annual data for six areas of sustainability in line with the UN Sustainability Goals. This year-on-year data available for the first time will allow brands and retailers to better measure progress towards meeting sustainability commitments.

The Trust Protocol underpins and verifies sustainability progress through sophisticated data collection and independent third-party verification. By working with Field to Market: The Alliance for Sustainable Agriculture and Control Union Certifications North America, the Trust Protocol enables brands and retailers to better track the cotton entering their supply chain. Brands who become members of the Trust Protocol will have access to aggregate year-over-year data on water use, greenhouse gas emissions, energy use, soil carbon and land use efficiency.

The Trust Protocol is a complement to existing sustainability programs and is designed from the ground up to fit the unique cotton mass-growing environment of the United States.

Last month the Trust Protocol was added to Textile Exchange’s list of 36 preferred fibres and materials that more than 170 participating brands and retailers can select from as part of Textile Exchange’s Material Change Index programme.

Sustainable solutions that pack a punch  

With over 6,500 visitors and more than 2,000 participants at a total of 720 minutes of live presentation sessions and with many potential new customers in the live info chat, the virtual interpack conference organised by Sappi was a resounding success. Sappi presented its latest developments, future prospects and current range of packaging and speciality papers at the event. In addition to further networking opportunities, the visitors took full advantage of the chance to get in contact with the Sales team.

• For the packaging of the future: sustainable, high-quality paper
• Second-generation barrier papers ensure optimal protection of goods as food packaging
• Providing what the world wants: fully recyclable packaging

Based on the motto ‘Pro Planet: Paper Packaging – welcome to the new pack-age’, the market leader in functional paper packaging presented numerous opportunities at its virtual interpack 2020 conference for its customers to package their food or non-food products in sustainable, premium packaging. In doing so, the company is contributing to the UN’s sustainability objectives. With the Sappi Guard range, Sappi presented barrier papers that render additional special coatings and laminations redundant and can be recycled in the paper stream. Featuring integrated barriers, they ensure that the product quality of foods and other goods is preserved. The second generation of barrier papers, now even more environmentally friendly, was also introduced at the virtual event. Another area of focus of the virtual interpack event was sealable papers, suitable for a wide range of packaging applications in the food and non-food sectors.

Of course, the concept of sustainability was also a key issue at the conference. As a home-compostable paper, Algro Nature meets the current demand for fully recyclable packaging. Sappi thus remains true to its goal of presenting its customers with more and more environmentally friendly solutions for the benefit of people and the environment.

‘We were overwhelmed by the success of our first virtual interpack conference, but we look forward to having direct contact again in spring 2021 in Düsseldorf,’ says Thomas Kratochwill, Vice President Sales & Marketing Packaging and Speciality Papers at Sappi Europe, with regard to the delayed interpack conference.

• Bemberg™ presents a great deal of novelties with a true key-statement for sustainability: Let’s Make it Circular!
• The lifespan of Bemberg™’s regenerated cellulose fiber Cupro derived from cotton is fully circular: from the source to manufacturing.

“Sustainability is the founding pillar of our company,” says SHUNSUKE SATO, sales manager of Bemberg™ by Asahi Kasei. “Indeed, the smart fiber is made from a cotton linter which is pre-consumer material, a natural derived source, that doesn’t deplete forestry resources”.

In Bemberg™’s production the whole sustainable closed-loop process is supported by the LCA study, signed by ICEA (Istituto per la Certificazione Etica e Ambientale) and validated by President of Ecoinnovazione Paolo Masoni ex Research Director of ENEA (Ente per le Nuove tecnologie, l’Energia e l’Ambiente).

While recyclability is granted by the Global Recycle Standard - GRS certification by the renown Textile Exchange (an influential guarantee that involves the whole production process and supply chain behind the company’s smart yarns), Bemberg™ yarns are also entirely biodegradable and ecotoxicity-free - meaning that at the end of their life circle they break down into the environment leaving no trace in terms of toxic substances as attested by the Innovhub-SSI report.

A special focus deserves Velutine™ Evo, the new fibrillation finishing technology for Bemberg™ fabrics only that guarantees another level of sustainable benefits without sacrificing the Bemberg™ amazing and unique touch. As part of the company’s continuous innovation, Velutine™ Evo brings better environmental, energy and water profiles for the benefit of Bemberg™ partners in the manufacture of their ranges.
The sustainable achievements of the new finishing technology have been measured by LCA - Life Cycle Assessment study by ICEA and proved to guarantee environmental benefits such as -16.5% of greenhouses gas emissions and -21% of overall consumption of energy resources. On top of that Velutine™ Evo means also -20.5% of electricity savings, -15.9% of steam production and -19.5% of water consumption.

The first Bemberg™ partner to present a commercial collection enriched by Velutine™ Evo is the Portuguese Matias & Araújo. With an innovative spirit, dynamism and a determined entrepreneurial spirit, the company is a leading knitwear producer for the textile industry.

Bemberg™ collaborated also with the premium brand CAALO that is making its mark in the outerwear market with its Sustainably produced Functional-Luxury proposal. For SS20, CAALO uses Bemberg™ lining because of the sustainability properties and it’s unique colour.

CAALO uses as much eco-friendly and sustainable materials as possible without compromising on design or quality. This Bemberg™ lining was a perfect fit. This versatile blazer features a removable hood, hidden welt pockets, button closure, and removable cargo pockets.

Non-contact precision spray technology enhances productivity, sustainability and process control

Baldwin Technology Company Inc. has announced that it will showcase the TexCoat G4 non-contact precision spray fabric finishing system at the Techtextil North America tradeshow, held from May 12 to 14, 2020, in Atlanta (booth #3048).

With extensive sustainability benefits, unprecedented tracking and process control, and industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, as well as minimal water and energy consumption. 

Baldwin’s innovative non-contact spray technology eliminates chemistry dilution in wet-on-wet processes. The TexCoat G4 consistently and uniformly sprays chemistry across the fabric surface and applies it only where needed, on one or both sides of the fabric. Customers can expect no bath contamination during the finishing process, as well as minimal downtime during changeovers, which are made easy with recipe management that includes automated chemistry and coverage selection.

The TexCoat G4 also enhances sustainability by wasting no chemistry during color, fabric or chemistry changeovers, and because only the required chemistry volume is applied to the fabric, wet pick-up levels can be reduced by up to 50 percent—leading to 50 percent less water and energy consumption. Furthermore, in single-side applications, drying steps can be eliminated for various textiles, including those that are back-coated and laminated, thereby streamlining and simplifying the production process.

Focus on Sustainability and Climate Change

Passion for Cotton: The 35th International Cotton Conference Bremen starts on 25 March in the Hanseatic city’s historic Town Hall. But before subject-specific questions are discussed in depth in the individual sessions, the concise and inspiring keynotes by leading business experts from science and industry will draw attention to the current trends and challenges in the industry at the start of the conference. A large part of the presentations is shaped by the current discussion on environmental and sustainability issues and the resulting consequences for the global economy.

Climate Change and Sustainability

“Climate change - a storm in a teacup?” asks Kai Hughes, Executive Director of the International Cotton Advisory Committee, Washington D.C., USA, in a provocative speech. The aim of his presentation is to work out the challenges of climate change especially for agriculture and cotton production. This should form the basis for later discussion on concrete approaches and solutions within the cotton community.

With his lecture “The HUGO BOSS sustainability programme ... and what our customer has to do with it” Andreas Streubig, Director of Global Sustainability at Hugo Boss AG, Metzingen, Germany, rolls up the textile value chain from a different angle, starting at the consumer level. As a representative of a premium brand for women's and men's clothing, Streubig discusses sustainability as a strategic element of the corporate strategy and provides information on how elements of the strategy are being implemented at Hugo Boss.

Rüdiger Senft, Head of Sustainability at Commerzbank, Frankfurt am Main, Germany, looks at the changing role of banks in financing the cotton market. In addition to a general introduction to the topic of sustainability and banking regulation, Senft's presentation deals with the financing of the cotton trade from a social and ecological point of view.
The opening session on 25 March is hosted by Bill Ballenden, founder and owner of Dragontree, Swindon, UK, an online auction platform for the cotton trade. As a former cotton manager for Louis Dreyfus in Europe and Asia, Bill Ballenden has many years of experience in the industry.

Cross-Cutting Issues: Digitalisation, Gender, Value Chains

The subsequent session in the conference programme with the headline “A Wider View” is devoted to currently defining trends and important cross-cutting issues in the industry. This goes far beyond classic cotton themes.

A lecture by Mark Messura, Senior Vice President, Global Supply Chain Marketing for Cotton Incorporated, Cary, North Carolina, deals with the role of cotton in an increasingly digitally controlled supply chain. Significant keywords here are faster delivery times, vertical integration, transparency and traceability.

The presentation by Roger Gilmartin, Managing Director of Tri-Blend Consulting, Charlotte, USA, entitled “The secret recipe for timely, cost-optimised and high-quality cotton clothing” promises exciting and enlightening insights. Tri-Blend Consulting conducts studies on the performance of different cotton varieties during the entire consumption process to the finished yarn and evaluates them from an economic point of view.

Amy Jackson, from the Better Cotton Initiative, London, UK, presents ICA Liverpool's “Women in Cotton” initiative. With this commitment, the initiative aims to increase the influence of women in the cotton industry and give them a stronger voice, for example by building networks in cooperation.

Navdeep Singh Sodhi, International Strategic Management Consultant at the Gherzi Textile Organisation, Switzerland, gives an insight into the current development of the value chain for cotton, textiles and clothing in Africa. Looking ahead to the coming decades, also in view of population growth, Africa is seen as having a high potential for building economic structures to improve income and prosperity.

Thomas Schneider, Professor at the University of Applied Sciences in Berlin and active in the field of production planning and control, textile materials and materials testing will host the session. A leading light in his field, Thomas Schneider has more than 30 years of experience in scientific and application-oriented research in the textile and fibre sector, including at the Fibre Institute Bremen e.V.

The Lenzing Group completed the second pilot production plant announced in May 2018 for its innovative filament yarn TENCEL™ Luxe. Construction of the facility at the Lenzing site involving investments of EUR 30 mn could be concluded on schedule and within budget after 20 months of intensive work. The new pilot production line, which was put into operation in the middle of December 2019, gives Lenzing sufficient capacity for commercial programs and further application development.

Innovation in the eco-couture segment
Thanks to TENCEL™ Luxe, Lenzing is able to embed the issue of sustainability in the premium luxury market in combination with superior aesthetics. The properties of the fine filament yarn can be compared to those of silk due to its airy feeling on the skin and the matte finish. At the same time, TENCEL™ Luxe also stands out because of its extensive strength and high level of environmental compatibility. It is perfectly suited for very fine fabrics and as a blending partner for silk, cashmere and wool. “TENCEL™ Luxe opens up new markets for Lenzing and thus contributes to the successful implementation of their sCore TEN corporate strategy.

To Accelerate Public-Private Cooperation in Supply Chain Transparency

Asia Pacific Rayon (APR) has joined the first neutral and public traceability platform capable of visualising blockchain-based supply chain data from multiple companies and sources. It aims to help businesses across industries respond to consumer demands for ethical and environmentally friendly products.
The neutral and safe space for collaboration is provided by the World Economic Forum and created in collaboration with Everledger, Lenzing Group, TextileGenesis™, and the International Trade Centre. APR will contribute to Phase 2 of the initiative which seeks to incorporate more data sources.

“APR has started harnessing the potential of enterprise blockchain technology to enable customers to trace finished products back to the plantation forest origins on a smartphone app. To be able now to connect our data to other similar industry initiatives is a natural next step for APR, as is extending the benefits of our upstream traceability to the rest of the textile value chain.

Enhancing Follow Our Fibre with New Mill Sustainability Dashboard

Launched in mid-2019, APR’s blockchain-based Follow Our Fibre allows customers and stakeholders to scan its viscose product with a user-friendly app to access data that traces the product’s journey from plant nursery to viscose manufacturing and on to seaports. In October 2019, APR announced a collaboration with TrusTrace to integrate Follow Our Fibre with the latter’s T-Trace module. This helps connect APR’s upstream data to downstream textile value chain actors such as yarn and fabric customers and fashion brands.

More recently, a sustainability dashboard tracking key mill environmental performance indicators has been added to Follow Our Fibre. The dashboard presents APR’s performance in its first year of operations where a baseline has been established for quarterly tracking, reporting and continuous improvement.
The performance indicators follow key industry standards being set by ZDHC for Man-Made Cellulosic Fibres (MMCF), as well as the European Union Best Available Technologies (EU BAT).

In the 2019 `Hot-Button´ report issued by the forest conservation organisation Canopy, Kelheim Fibres attained a “green shirt” ranking. Many fashion brands already value the `Hot-Button´ report as a reliable indicator for sustainability for viscose fibre producers.

Raw material wood sourced only from certified sustainable forestry
The CanopyStyle initiative aims to achieve that no wood from ancient and endangered forests is used to produce viscose fibres. The audited companies must prove that they avoid these fibres and have implemented appropriate rules and procedures to check the origin of the wood. Performance in the areas environmental protection and innovation have been examined and evaluated by qualified external auditors; the report will be posted publicly in the first quarter of 2020.

Sustainable fibres for a changing market
“For years now Kelheim Fibres has consistently recognised the importance of sustainability and environmental protection. Now that resource saving and alternatives to plastics are of focal interest to the public and to the economy, our products are meeting with an even better reception from the market. Fibres produced in Germany with low emissions from certified sustainable timber meet the needs of customers seeking products that have a low risk of sourcing from ancient and endangered forests. “Having been awarded a `green shirt´ in the `Hot-Button´ ranking once again underlines this absolutely clearly!” says Matthew North, Commercial Director at Kelheim Fibres.
