From the Sector

Alchemie Technology, a leader in waterless, digital on-demand, smart dyeing technology, has today announced its partnership with HeiQ, a leader in textile innovation, as it prepares the production rollout of its NOVARATM digital multifunction finishing solution to the global textile market in Q3 this year.

NOVARA can apply single-sided, or simultaneous two-sided, coating of multiple finishes to specific areas of textile. For example, combining anti-odour and water repellence in one material.

“For example, using NOVARA for single-sided finishing of HeiQ Viroblock required 52% less chemistry, 66% water reduction and 50% less energy, whilst achieving a 99.7% reduction in antimicrobial activity after 15 washes at 400celsius. With the huge demand for high-performance antibacterial, antiviral finishing for face masks, medical apparel, gym wear, home furnishing, mattresses, and textiles for high-risk, high traffic areas such as train, plane seats, and more, our combined technology is critical for increasing protection and reducing environmental impact of these products” says Dr Simon Kew, Managing Director, Alchemie Technology.

NOVARA also enables unique lifestyle product innovations at lower production cost for fashion, sportswear, technical clothing, and upholstery such as combining sustainable odour control, skin care additives, and fragrance finishing, without impacting breathability, hand feel or wicking. It is suitable for finishing all fabric types, from 50 - 1000 gsm, including polyester, cotton, nylon and polycotton.

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.

• 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.

Reinach, Switzerland, and Westlake, Ohio, 2 February 2021 - Archroma, a global leader in specialty chemicals towards sustainable solutions, today announced a strategic partnership with technology innovator CleanKore, aiming to advance sustainable dyeing processes throughout the denim supply chain.

The agreement will allow Archroma and CleanKore to promote the benefits of each other’s technologies. This includes Archroma’s robust catalog of dyes and specialty chemicals along with CleanKore’s patented process of dyeing yarns at the denim mill that completely eliminates the need for potassium permanganate (PP) spray and laser booster to achieve the bright white abrasion effect in the garment finishing process. The result is a large and circular bright white core with a small ring of indigo dye. The technology does not just eliminate the chemicals associated in the PP spray and laser process, which is much safer for denim workers, it also allows to save significant amounts of water and energy throughout the manufacturing process from fabric to garmenting.

CleanKore initially looked at eliminating potassium permanganate due to its being classified as hazardous if inhaled or ingested, or in case of contact with the skin or the eye. It is also considered very toxic to aquatic life. No new equipment or capital expenses are needed to implement the CleanKore technology, which works on all denim fabric, including dark indigo, sulfur top/bottom and sulfur black.

This is where Archroma comes into the picture. Its global technical team of denim coloration specialists will provide support to denim mills seeking to implement the CleanKore technology and develop the desired looks and effects - with the right colors and chemical systems for their production set-up.

CleanKore estimates that the technology allows to save up to 15 liters of water per garment, or the equivalent to the drinking needs of 5 people per day, and up to 0.51 kWh of energy per garment, or the equivalent of five 100-watt light bulbs on for 1 hour. The CleanKore technology also leads to a 10% to 20% increase in production throughput, as a result of a faster garment wash-down and the elimination of PP spray.

For CleanKore CEO Darryl Costin Jr., the announcement comes at an ideal time for CleanKore: "We have successfully proven the technology with mill partners such as Arvind and other denim mills in Pakistan, Bangladesh, China, Vietnam, Thailand and the United States. The response from the industry has been overwhelmingly positive. Having a partner in Archroma, one that is highly respected for their innovation and emphasis on sustainability throughout the industry, will allow us to take CleanKore to the next level.”

Umberto Devita, Global Indigo Manager at the Archroma Global Competence Center for Denim & Casualwear, adds: "CleanKore is perfectly aligned with the 3 pillars of 'The Archroma Way to a Sustainable World: Safe, efficient, enhanced'. 'Safe' through the elimination of a potentially harmful substance and the protection of the denim workers, 'Efficient' through the reduction of resource consumption, improved productivity and cost-effective profile. And 'Enhanced' through the gorgeous colors and effects allowed with Archroma's innovations and systems, in particular our aniline-free* Denisol® Pure Indigo and Diresul® sulfur dyes. We look forward to help promoting an innovation that will help with many of the challenges facing our denim customers throughout the world. Because it’s our nature."

Singapore – As global interest in sustainable textile production continues to soar, mills that have adopted Huntsman Textile Effects’ all-in-one ERIOPON® E3-SAVE textile auxiliary for polyester processing, which launched one year ago, have collectively saved more than 130 million liters of water.

Demand for polyester fabric is being driven by seemingly insatiable consumer appetite for sportswear and athleisure clothing. Sales in the sector have been on an upward trend for several years and are even proving resilient amid Covid-19 market disruption. However, dyeing of polyester and its blends has traditionally been resource intensive, time consuming and costly.

Huntsman Textile Effects’ next-generation ERIOPON® E3-SAVE textile auxiliary was engineered to address these challenges. It eliminates the need for separate pre-scouring, allowing pre-scouring, dyeing and reduction clearing to be combined in a single bath. Mills that use ERIOPON® E3-SAVE can thus dramatically shorten the polyester dyeing process and save water, energy and cost.

“Our innovations aim to help mills improve their productivity and competitiveness while also contributing to the textile industry’s shift to more sustainable practices and a reduced environmental footprint,” said Kerim Oner, Global Marketing Manager, Huntsman Textile Effects. “With ERIOPON® E3-SAVE, we have harnessed the unparalleled technical expertise and application know-how of our research and field teams to develop a product that is proven to reduce costs for mills and that meets current and anticipated industry sustainability standards.”

Dae Young Textile Vietnam Co., Ltd, a forerunner in sustainable textile production in Asia, was an early adopter of the ERIOPON® technology. Results from bulk production show that ERIOPON® E3-SAVE has reduced process time by over 20 percent and water consumption by over 50 percent, delivering annual cost savings of up to 30 percent.

“ERIOPON® E3-SAVE delivers a combination of best-in-class performance and value. It allows us to have the shortest possible processing cycle, which is key for us to deal with increasing industry pressure for faster turnarounds,” Jeong Won Oh, General Manager, Dae Young Textile Vietnam, said. “Alongside dramatic time savings, we are also saving water, energy and ultimately cost. Huntsman’s best-in-class products and high level of technical support help keep businesses like us productive.”

This unique polymer technology of ERIOPON® E3-SAVE promotes controlled exhaustion to ensure right-first-time level dyeing. It extracts oil and oil-based impurities from the fiber during processing and displays a high affinity to disperse dyes, enabling the rapid removal of unfixed surface dyes from the fiber during reduction clearing. The technology also enhances reproducibility and improves wet- and rub-fastness.

ERIOPON® E3-SAVE saves time, water, energy and cost in polyester dyeing by combining pre-scouring, dyeing and reduction clearing in a single bath. An advanced multi-action dyeing auxiliary in the dyEvolutionTM range, it delivers environmental and economic sustainability.

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.

After becoming the first company in the world awarded both the rigorous EU Ecolabel and Nordic Swan Ecolabel, ISKO has recently reached another important milestone in its long-standing responsible journey: it has become the first Turkish denim manufacturer awarded with STeP by OEKO-TEX® modular certification system.

The certification results in a powerful tool to implement the company’s Responsible Innovation™ approach. This mindful and holistic vision tackles environmental and social responsibility to reach the goal of a 100% sustainable and ethical denim production, based on three main pillars – creativity, competence and citizenship.

“Responsibility and innovations go hand in hand, at ISKO,” explained Senior Sustainability and CSR Executive Ebru Ozkucuk Guler, “To be awarded with such a prestigious certification is proof that one has to look at the big picture: sustainable actions need to involve and take into account the entire value chain, in the long run, considering not only production steps but also the development of a healthy and safe work environment. It is the perfect ending to a very fulfilling year, we are eager to see what 2020 will bring.”
