From the Sector

ANDRITZ will be presenting its innovative solutions for nonwovens production and textile manufacturing at INLEGMASH 2022 in Moscow, Russia, from March 14 to 17.

AIRLAY TECHNOLOGY
Protecting the environment and conserving natural resources require new technologies. In the textile-related industries, the current challenge is to develop industrially and economically viable solutions to use eco-friendly fibers in nonwovens. ANDRITZ focuses on the airlay nonwoven application for hemp fibers (used in mattress production, insulation, ...) and also geotextile end uses.

TEXTILE RECYCLING TECHNOLOGIES
ANDRITZ Laroche is a leading supplier of fiber processing technologies such as opening, blending, and dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. One focus of this product range lies on complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end uses. ANDRITZ will present recycling technologies for end-of-life textile products that can be used in multiple applications, such as automotive, insulation, mattresses, and furniture felts.

Customer awareness and regulations are pushing apparel brands to recycle their textile waste and use the recycled textile fibers in their own products. To support ANDRITZ customers, a team with process know-how is available to conduct customized trials in our advanced technical center located at the ANDRITZ Laroche facilities in Cours, France.

BAST FIBERS
For the demanding Russian market for technologies based on bast fibers, ANDRITZ will present innovative products and the valorization of bast fibers, in particular hemp.
ANDRITZ Laroche is a player in the textile waste recycling sector, with airlay nonwoven technologies but also bast fiber decortication and cottonizing lines.

These eco-friendly fibers are used to spin yarn mixed with cotton, saving cotton as raw material, which reduces the consumption of water, pesticides applied in its cultivation and chemicals used during the dyeing and finishing processes.

For its FW 22/23 collection, ECOSENSOR™ by Asahi Kasei Advance presents a high-tech fabric collection, which implements a new generation of values, with the aim of keeping nature, body and mind in harmony.

ECOSENSOR™’s new references meet the needs of the contemporary consumer, such as durability, wellbeing and performance. Furthermore, they are made with certified ingredients, through a completely traceable and transparent production process and supply chain. Being capable of combining active climate control, exquisite touch, lightness and comfort with sustainable values, ECOSENSOR™’ stands out as a unique eco-high-tech performance proposition in its market.

The whole collection is focused on advanced technology and environmental responsibility. Thanks to ECOSENSOR™ by Asahi Kasei Advance’s unique value-chain based on recycling technology, most part of its yarns are certified by the renowned GRS (Global Recycled Standard). Even the dyeing and finishing phases - key moments for  performance wear - have been certified by international labels such as bluesign® and OEKO-TEX® Standard 100.

Among the compositions of the fabrics, dominant are the recycled polyamide (58%) and polyester (39%) yarns. The stretch component present in 22 articles of the collection is based on ROICA™ EF by Asahi Kasei - the sustainable recycled stretch yarn made from pre-consumer waste. In addition, 8 fabrics of the FW22/23 collection are made of Bemberg™ by Asahi Kasei - the high-tech yarn born from the transformation of cotton linters through a fully circular, transparent and traceable process with an amazing precious hand, optimal moisture management characteristics,  whose end of life guarantees its biodegradability and it also carries GRS certification.

Featuring a total of 36 fabrics, the collection is composed of:

• 7 outerwear fabric
• 22 sportswear fabrics
• 7 innerwear fabrics

• Alchemie Technology asks world leaders to cut energy and CO2 emissions from global fashion industry

Alchemie Technology, innovator of low energy, waterless, textile dyeing and finishing technology, is calling on COP26 leaders to support the global fashion industry in the adoption of new manufacturing technology, which will dramatically reduce carbon emissions and fashion’s impact on climate change.

While the fashion industry is one of the most polluting on the planet, second only to oil and gas, and greenhouse gas emissions from textile dyeing at around 3% of global emissions outweigh that of all international flights and maritime shipping combined, it is an industry that can also reduce CO2 emissions the fastest, just by changing the way it dyes fabrics.  

Fabric dyeing is the most polluting part of fashion and activewear manufacturing, involving industrial scale dye baths and huge amounts of dye chemicals, steam, electrical power, and consequent high CO2 emissions.  Repeated washing of the dyed fabric, required to remove dye residue, is responsible for 20% of the world’s wastewater pollution and excess dye is discharged into waterways, affecting the health of some of the world’s poorest communities. In more regulated areas, water pollution is reduced through reliance on energy intensive water treatment plants.

However, an environmental step change can be achieved by adopting new digital technology that can dye fabrics with an 85% reduction in energy consumption and a dramatic 95% reduction of the 1.3 trillion litres of water currently used by the industry each year.

For example, dyeing one polyester shirt using current methods generates 4.5 litres of wastewater and produces 0.17 Kg of CO2, compared to low energy digital technology, which uses less than 0.2 litres of water and reduces carbon emissions to 0.03 Kg.  Multiply these numbers by the billions of garments dyed each year and the scale of the environmental problem, if nothing changes, is clear to see.  Equally, the amount by which the textile industry can improve its carbon footprint is dramatic and can be done quickly if action is taken now.
Dr Simon Kew, Managing Director, Alchemie Technology comments “The technology now exists to enable the textile industry to make a significant contribution to helping meet the world’s net zero, climate change goals. But it requires the support of governments through investment, grants and legislation and the critical effort of brands, and their manufacturing supply chains to work together to make the change.”

With its resource-saving dyeing technology, We aRe SpinDye takes place in H&M's latest Innovation Stories collection called Co-exist.

The use of We aRe SpinDye's technology contributes to reducing both water consumption and CO2 emissions, which in turn leads to a lower impact on the world's ecosystem and creates conditions for our co-existence with nature.

Up to 24% of a garment's entire climate footprint occurs during dyeing. We aRe SpinDye's technology can reduce the consumption of the earth's resources in textile production. On average, the reduction of water is -75%, chemicals -90% and energy consumption and CO2 emissions -30%.

In just one year, the clothing industry uses 9 billion cubic meters of water (which is in line with the annual need for drinkingwater for the entire population of our planet) and 168 million tons of process chemicals to dye fabrics. We aRe SpinDye now hopes that more players in the industry will pay attention to the ways that are available when it comes to resource-efficient dyeing process and quickly implement this technology in their production.

"The enormous resource consumption in the dyeing process is a global problem that must be addressed on a broad front. It is therefore inspiring to work with major brands with an organization that is sensitive to cutting-edge expertise and at the same time shows a willingness to work together to achieve common goals", says Andreas Andrén, CEO of We aRe SpinDye.

The Turkish company ARIKAN Mensucat Industry and Trade Inc. was founded in 1993 and is located in Kahramanmaraş, one of the southernmost cities of the country. Today, the family-owned company employs around 1,500 people and finishes around 55 tons of knitwear every day. In addition to many well-known Turkish fashion manufacturers, ARIKAN also supplies international manufacturers in Europe, Russia, the Gulf States and other leading international markets.

The German machinery manufacturer BRÜCKNER supported the Turkish company from the very beginning. From the foundation of the dyeing and finishing plant, BRÜCKNER supplied three stenters for the finishing of the high-quality knitted fabric in 2014. Two more lines followed in 2016. For decades, BRÜCKNER has been the market leader for the finishing of knitted fabric. Especially for very fine and elastic fabric, special line configurations and technological know-how are necessary to be able to produce a high-quality end product. During the drying and heat-setting process, for example, extremely accurate and uniform temperature distribution over the entire length and width of the dryer is essential. In the BRÜCKNER stenter this is achieved, among other things, by the alternating arrangement of the thermal zones every 1.5 meters and by the proven split-flow air system.

The machine operators at ARIKAN appreciate the easy control of BRÜCKNER lines. The visualization is intuitively designed and offers many auxiliary systems for an optimized production process. In addition, significant energy savings can be achieved with just a few changes to the machine parameters.

The management at ARIKAN attaches great importance to energy saving, especially in the fabric finishing department. The drying process is one of the most energy-intensive in the entire process chain, therefore the biggest savings can be made here. These have a direct impact on the manufacturing costs of the textiles and thus on competitiveness in the market. In the meantime, talks are already in progress for another BRÜCKNER line which will include a very special feature: a combined heating system for the dryer. For many customers - and so also for ARIKAN in Turkey - e.g. steam energy is available free or very cheap. With the combined heating system developed by BRÜCKNER it is possible to use this steam energy for heating up the dryer and thus to achieve significant savings. If the available steam is not sufficient for a running process, it is automatically switched over to gas heating. This mode of operation does not only have an effect on the energy costs, but also makes a considerable contribution to environmental protection.

Combining expertise for more sustainable fashion
Ever wonder how much water was used to make your favorite cotton T-shirt? About 2,700 liters, or roughly three years of drinking water. What first comes to mind is probably the water that was essential to growing the cotton crop. Surprisingly, cotton is a drought-tolerant plant, and often less recognized is the strain that can be put on water resources to dye cotton textiles.

Progress is being made across the industry to lessen the strain on our precious water resources. Over the past several years, Dow collaborated with Cotton Incorporated to research and validate their product, ECOFAST™ Pure Sustainable Textile Treatment, that can help drastically reduce water and chemical use during the dyeing process. Major fashion brands are integrating it into their supply chain to dye more sustainably, without sacrificing color or quality.

Problem
Cotton dyeing is very resource-intensive and puts strain on local waterways. A large amount of water is used in the dyeing process – up to 5 trillion liters a year, or nearly enough to supply all of humanity with drinking water. Significant amounts of chemicals and dye are needed to get the desired colors consumers expect too. This is part of the reason textile mills account for 20% of industrial water pollution globally. Wastewater from the dyeing process can be polluting and require costly treatment and these challenges are found in regions that already face water scarcity.

Solution
Reforming processes in an industry as established as textiles is no easy feat. Collaboration across the sector is needed to bring about sustainable change. With that in mind, Cotton Incorporated approached Dow. They wanted help scaling a cotton technology to support more sustainable textile dyeing.Leveraging Cotton Incorporated’s industry expertise and Dow’s material science knowledge, they worked together to understand and validate the benefits of our patented ECOFAST™ Pure Sustainable Textile Treatment.

How can colors be more responsible?  
ECOFAST™ Pure is a pretreatment applied before the dyeing process to produce cationic cotton. This means the charge of cotton is permanently changed from negative to positive, so it acts like a magnet to attract negatively charged dye to the material. How does that benefit the textile mill? It significantly decreases the amount of water, chemicals, dye and energy needed to color cotton. A third party reviewed and validated life cycle assessment, available by request, helped further prove the benefits.

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

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

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

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

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

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

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

• 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.”

The human, environmentally-friendly and cutting-edge imprint of ECOSENSOR™ ultimate collection reflects a vision for a more responsible way of fabric manufacturing. A new force of nature, because story-telling truly must match the story-making.

• Kettelhack GmbH – a German leader in the dyeing and finishing of monochrome fabrics for high-quality and durable workwear and bed linen – has this year retired its existing Monforts sanforizing line after 35 years of daily service, replacing it with a new one.

The first line was installed in 1985 during a decisive time for the company.

Taking the helm in the early 1980s, Jan Kettelhack – the current CEO, owner and great grandson of Heinrich Kettelhack who founded the company back in 1874 – made a number of decisions that have secured its success over the following decades.

In 1982 Kettelhack had to vacate its existing plant in the city of Rheine due to urban development restrictions and despite a general sense of crisis in the European textile industry at that time, opted to relocate and build a new highly automated plant that was not reliant on mechanical and personnel-intensive processes. This was aligned with a greater focus on competitive international sales.

From 1986, the company’s proficiency as a specialist in solid-colour textiles led to workwear textiles becoming a bedrock of the business. Continuous investments in machinery and technical equipment have resulted in a fully integrated and rationalised single source site dedicated solely to what the company does best – the expert dyeing and finishing of textiles.

Crucial process steps

These stages in the textile value-added chain, Jan Kettelhack has observed, are crucial to the quality of a final product in workwear – whether it stands the test in everyday use, how comfortable it is, and how many washes it can withstand.

Central to this is the sanforizing process, which pre-shrinks a fabric by compressing it prior to washing. This limits any residual or further shrinkage in a made-up finished garment to less than 1%, to ensure perfect comfort and fit over an extended lifetime.

“We certainly can’t complain about the performance of the old Monfortex sanforizing line which gave us so many uninterrupted years of service, but certain spare parts for it were becoming increasingly hard to source, the control unit was becoming a little unstable and we couldn’t risk potential interruptions to our production schedule,” says Kettelhack plant manager Hendrik Pleimann. “In many ways, the new Monfortex sanforizer is much the same as the old one in terms of its mechanical reliability and robust construction, but of course today’s drives are much more efficient, and when it comes to the automation features and control units – and the data we can generate and analyse for increasing efficiency – that’s a whole new world.”

Qualitex 800

The two-metres-wide Monfortex line benefits from the latest Qualitex 800 control system which allows all parameters to be easily automated via the 24-inch colour touchscreen, including production speed, control of all fabric feed devices, rotation spray or steaming cylinder options, the width of the stretching field and the rubber belt pressure.

The integrated Compactomat system allows a continuous indication and control of the shrinkage values and the temperatures of the shrinking cylinder and felt calender. Up to 10,000 separate process parameter records can be generated and stored by the data manager.

Full line management can be optimised via the batch-specific calculation of all process material consumption and water and electricity use, with any standstill times analysed and immediately corrected for the future.

Any further assistance required is available via Monforts Teleservice, with direct connection to technicians and virtual access to machine analysis.

Professional

Commissioning of the new Monfortex line at Kettelhack commenced in January and it was fully operational in a relatively short time.

“This was a very professional installation provided by the Monforts team with whom we have a very good relationship dating back many years, and everyone knew what was required from both sides,” says Mr Pleimann. “Our operators have found the new line very user friendly and we are very pleased with how everything proceeded so smoothly. An unexpected benefit is that the new line is also a lot quieter, of course, which is something our operatives are appreciating.”

Key features of the Monfortex line are the proven fabric preparation, weft straightening and spreading units, prior to the compressive shrinkage machine with a 750mm shrinking cylinder, and a felt calender equipped with 2,000mm diameter drying cylinder. The line also features an integrated automatic grinding unit.

Customer service

Kettelhack is processing primarily cotton and polyester woven fabrics, with lyocell becoming increasingly popular in workwear for its softness and comfort.

As part of its customer service, the company stocks more than a million metres of grey fabric and at least 1.2 million metres of finished and rolled standard fabric in its warehouse at any one time, with a further 750,000 metres permanently in production.

While a significant cost, this commitment ensures Kettelhack customers can be fully flexible and rely on it as a partner.

“As a family-run company with around a hundred employees, Kettelhack operates very differently to bigger businesses which have to constantly consider their immediate quarterly profits,” Mr Pleimann concludes. “The thinking at Kettelhack is in terms of the next twenty years and ensuring that the business will be just as successful for the next generation as it is today. We also have a very flat organisational structure in which everyone is involved and takes an active part, which makes it a very nice place to work.”
