From the Sector

• 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 RUDOLF GROUP is an uncontested agent of positive change especially when it comes to pioneering technologies that help transforming the textile and fashion industries. A shining example of conscious leadership played by the RUDOLF GROUP over the past decades is the invention and introduction of fluorine-free Durable Water Repellency (DWR) for textile and apparel. Since 2003, the RUCO-DRY product line has gradually convinced the industry that water-resistance can be achieved through the study and replica of natural models. “Biomimicry and the study of lotus leaves and bird’s feathers were instrumental in developing the very first fluorine-free DWR’s” says Dr. Gunther Duschek, Managing Director at RUDOLF GROUP.

Fifteen years later, RUDOLF GROUP does it again and takes a significant leapfrog. It pushes the boundaries of R&D well beyond fluorine-free, embraces nature and introduces water repellent performance entirely based on natural components. “We are launching two brand new, distinctive product propositions entirely manufactured from natural sources that do not compete with human and/or animal nutrition” continues Dr. Duschek.

RUCO®-DRY BIO CGR is an absolute breakthrough and the first Durable Water Repellent (DWR) agent based on plant-derived processing wastes. In fact, RUCO®-DRY BIO CGR is made of natural waste that accumulates as by-product during the processing of cereal grains in the food industry. The leftover material that would otherwise be disposed of is refined to create a powerful water and stain repellent textile finish.

“By turning natural waste into DWR we have optimized the biologic character of RUCO®-DRY BIO CGR where the active component is made of more than 90% bio carbon” states Dr. Dirk Sielemann, R&D Director at RUDOLF GROUP. He continues: “Although most of the product is composed by recycled biomass, RUCO®-DRY BIO CGR meets the performance and durability of conventional water repellent textile finishes”.

RUCO®-DRY BIO NPE is an equally outstanding product innovation where DWR is entirely based on a carefully selected mix of natural plant extracts. The well-balanced mix of plant-based ingredients combines excellent water and stain repellent effects with breathability and a natural handfeel. 

Unlike other 100% renewable raw materials, those used in the making of RUCO®-DRY BIO NPE are chemically and genetically non-modified and are not used as food, feed or fuel. Furthermore, all of the plant extracts that compose RUCO®-DRY BIO NPE are subject to a strict conservation and sustainability framework. “That’s why the supply of RUCO®-DRY BIO NPE is likely to remain limited to the creation and marketing of performance outdoor and sports apparel programs embedding state-of-the-art sustainable technology” concludes Dr. Duschek.

Both RUCO®-DRY BIO CGR and RUCO®-DRY BIO NPE are marketed through the BIO-LOGIC trademark, registered by RUDOLF GROUP.

Sicomin’s latest marine collaboration with Sonntag Fins sees its industry leading GreenPoxy® 33 bio-based epoxy resin used for custom carbon fibre windsurf fins - combining speed, fatigue performance and sustainability for some of the fastest sailors afloat.

Targeted at windsurf slalom sailors, racers and speed sailors, each Sonntag fin is a custom made product, tailored specifically to the user based on a discussion about riding style, physical size and weight, as well as how the rider likes to load the fin whilst sailing.  This attention to detail and bespoke manufacturing places a huge importance on the performance and consistency of the raw materials used, with all new materials having to be validated in production, on the test rig in the lab, and on the water by the team riders.

With this in mind, Sonntag Fins approached Time Out Composite, Sicomin’s German distributor,  looking for a new resin system that could reduce cycle times and improve manufacturing output.  Bio-based systems were discussed, but the first product used by Sonntag was Sicomin’s SR1280 laminating system which delivered immediate results, enabling shorter cure cycles, and exceeding all of the previous mechanical test targets.

In 2020, Sonntag and Time Out Composite revisited the topic of a more sustainable epoxy resin system. It was the perfect time for Sonntag Fins, with their new unique bright green UV resistant outer finish, to go green on the inside too with Sicomin’s GreenPoxy® 33 resin.

Test fins were produced with the new material performing well in production trials. Pure resin samples were also tested and post-cured at 140 ̊C, with the new GreenPoxy® 33 samples showing significantly higher elongation at maximum resistance, meaning the cured epoxy was less brittle and susceptible to damage should a customer’s fin meet a rock. With mechanical properties improved, Sonntag switched production to GreenPoxy® 33 in August 2020.

Sonntag fins are manufactured in CNC machined aluminium moulds using GreenPoxy® 33 and a bespoke lay-up of woven, stitched biaxial and heat-set unidirectional carbon fibre fabrics in four steps:
• The first step in the moulding process is the application of Sonntag’s unique green in-mould coating.
• Next, the individual fabric plies, cut using precisely machined templates, are placed into the mould and then wet-out with the low viscosity epoxy. With the laminate stack complete, the mould is closed and loaded into a heated press for around 2 hours to consolidate and cure the fin.
• After curing, the demoulded fins are tempered in an oven at 140 ̊C, then only a light sanding is required to create the final surface roughness for optimum flow characteristics in the water.
• Finally, the fins are cut to the required length and the base adapter is molded to the epoxy-carbon blade in a specific mould.
With each fin being optimized for its rider, it is critical that each piece produced will bend and twist in exactly the way it has been designed to do so, providing the rider with exactly the feel and feedback they want for their board and fin. Each Sonntag fin is tested on a unique CNC controlled servo and stepper motor driven test bench that Joerg has developed, building a database of test results that not only ensures the products perform as designed but also validating the consistency of the manufacturing process and raw materials.
“We produce high-performance windsurfing fins that need to accommodate significant loads during sailing. Fins need to combine flexibility with extremely high torsion stiffness that places high interlaminar shear forces on the resin, especially in our softer fins.” commented Joerg Sonntag, MD, Sonntag Fins. “A key requirement for us is a resin that maintains its mechanical properties for many years, and this is where the Sicomin systems deliver”

• Composite textiles for modern mobility
• Extremely lightweight, high tensile components by vombaur

In the snow, on a plane, in an electric vehicle or on a bicycle: no matter where and how we are on the road – composite textiles by vombaur ensure that we make good progress. With materials that are both extremely light and extremely reliable.

Lightweight components for modern mobility
Modern mobility relies on high-tech lightweight components Narrow textiles by vombaur are woven from high-performance fibres. On looms that are specially made for particularly demanding composite textiles: the textile company uses special machines to produce high-tech woven tapes with closed selvedges and elasticated UD tubulars that retain their 0° orientation over the entire length of the component – regardless of the diameter. Since they do not exhibit undesired break points caused by seams or welding, they not only have a particularly high bursting strength, they are also extremely reliable and durable.

Challenging applications
"From snowboards to aerospace – the applications for our composite textiles are demanding; the mechanical, chemical and thermal requirements are extreme," explains COO Christoph Schliefer. "As a development partner, we at vombaur are therefore often involved in product development at an early stage. We specify our woven tapes and tubulars individually for each project to suit the specific task at hand."

High quality raw materials, wide variety of geometries
The variety of shapes is virtually unlimited. vombaur manufactures 3D fabrics for composites in individual special shapes from carbon, aramid, glass or hybrids. Curves, edges, tubulars, spiral fabrics – the shape of the 3D fabrics, like the material itself, depends entirely on the task at hand. Powder or non-woven coatings create additional important properties.

Pioneering tech tex
"Developments in the field of modern mobility are happening at a rapid pace," emphasizes Schliefer. "With our composite textiles for extremely lightweight and high tenacity components, we at vombaur are also pushing these developments forward."

The textile industry, one of the major industrial sectors worldwide, is going through a significant revolution, with changes taking place in various sections of textile processing. Biotechnology and biomimicry, for example, are continuously playing an important role in redefining the influence of the textile industry on society, and so is progress made in auxiliary chemistry, with advances investigated and then applied in almost every section of textile processing.  The outcome is amazingly promising.

Modern, real science is inextricably intertwined with environmental consciousness and they are definitely not mutually exclusive.

At RUDOLF GROUP modern, real science means pushing R&D so to constantly explore new technology and innovations that help transform the textile and fashion industries. We work to reduce the overall dependency on traditional and virgin resources.  Getting textile manufacturers as well as brand and retailers on board is key to achieve real change. By 2030 we aim for a significant fraction of our products to be either sourced through paths alternative to the traditional petrochemicals, or by upcycling waste and/or byproducts from other industries.

“This is the kind of genuine, tangible, environmental consciousness that truly defines us and that entails that RUDOLF GROUP has a responsibility for the needs of society as a whole.” Said Alberto De Conti, Head of Rudolf Fashion Division “We have a maniacal attention to the environmental impact of our operations and products. We have truly embedded in ourselves the notion that “sustainability” is a key issue and critical to the long-term survival of our company and of society at large. “

The combination of modern, real science and environmental consciousness leads to what RUDOLF GROUP call aspirational chemistry something unique and something that positions us as shining example and guiding light throughout the industry. That is, in fact, BETTER CHEMISTRY.

Two are the innovations rooted in aspirational chemistry that RUDOLF HUB1922 presents. The first one is our WASHLESS technology and the second one is a brand new launch: LASER SMOOTHER, which supports laser technology and helps creating much better denim looks.

WASHLESS

HUB1922 WASHLESS, which can be applied to both denim and non-denim, is the simultaneous application of
-    proprietary fluorine-free DWR (Durable Water Resistance) based on biomimicry to repel dirt
-    anti-microbial, anti-bacteria and anti-viral, non-migrating chemistry to stop body odour.
The combination of the 2 translates into garments that don’t require to be washed as much.

Life cycle assessment studies on clothes, detergents and washing machines show that home laundering is always the most energy‐demanding period during these products' life cycle, even higher than production or transportation phases.

“WASHLESS aims at changing consumer habits in clothing maintenance to a more environmentally friendly direction and represents a change that is the most feasible and efficient. Making washing machines obsolete is impossible, but even though the technologies in clothes cleaning have improved greatly, the washing frequency has not been reduced. We own more and more clothing and wash it more frequently. This increased amount of washing counteracts the technological improvements in home laundry. “ said De Conti.

It is only by understanding the climate change impact associated with home laundering that product innovations and consumer education can be explored. Studies consistently show that a carbon dioxide reduction of 105 MT and electricity savings of 142 thousand GWh can be obtained by reducing home laundering, on average, by 1/3. This is roughly equivalent to removing 12% of the 140 M passenger cars in the US, or taking 23 coal power plants off the grid. In addition, more than 60% of water consumed while laundering (2,000 billion liters) can be reduced through these strategies.

LASER SMOOTHER

Laser denim is the current dominant technology available to the denim industry to create locally abraded areas, vintage effects, whiskers, patterns, patches, and even intentional holes and tears in a garment. Laser technology uses less water, harmful chemicals (such as potassium permanganate) and energy to create a wide variety of denim looks.

However, laser is not always able to produce the desired look, on the desired fabric, in the desired time. Therefore, chemical companies have been developing laser boosters that can be pre-applied to the garments in order to intensify the effect of the laser to mimic heavier bleaching applications. Unfortunately, laser boosters can create blurred images where the definition is lower and the overall image less natural.

The brand new RUDOLF HUB1922 LASER SMOOTHER is an all-in-one formulation, very easy to pre-apply to garments before laser burning and that return a very natural image which is very similar to the highly desirable hand scraping. Laser smoother can be applied by traditional exhaust or through nebulization and it dries at normal temperature in normal tumble driers.  Advantages of LASER PRIMER are:

•    Remarkable enhancement of the fabric’s characteristics (heightening of material)
•    Overall effect much more natural and similar to manual scraping (craftsmanship dimension)
•    Reduced required laser power to achieve the wanted effect (conspicuous energy saving)
•    A faster laser burning process (significant time saving, depending on the final effect)
•    Any other chemical spray is not required (environmental friendliness)
•    Reduced cost compared to other solution (financial viability)

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.

Energiapura – Production of reusable, customised protective masks that are also fashion accessories

• The Italian company, a specialist manufacturer of functional sportswear, conducted research and began producing masks in response to the COVID-19 crisis
• Using Mimaki sublimation printers, the masks can be customised, getting away from their connotation with hospitals and transforming them into a fashion accessory

From functional sportswear to combatting the spread of the Coronavirus: Energiapura, an Italian company has developed a mask that meets the Class I medical device requirements. The EP PA 2020 (Energiapura Pure Air) facial device, optimised for air filtering and breathability, provides protection while working, and can be reused. But Energiapura has gone even further, branding and customising the masks with sublimation printing.
The EP PA 2020 mask, compliant with 93/42 EEC Medical Devices – Class I washable, meets the essential requirements of UNI EN 14683:2019. Having redirected the manufacturing process, Energiapura is now stepping up production levels to meet the rising demand from hospitals, pharmacies, chemists, companies and consumers.

Pure Air, Energiapura’s mask
The EP PA 2020 is based on a functional concept: protection, breathability and reusability are the main principles. EP PA 2020 is made up of three layers of fabric: the first, the outer layer, is DWR-treated polyester, the second is TNT polyester, providing a filtering function, and the third, which comes into contact with the face, is polyester containing special fibres, such as coolmax and carbon.  Therefore it can be reused via normal washing and steam ironing, which also sterilises it.
The CEO of Enegiapura, Alberto Olivietto explains the idea of the customisation of the mask: “We wanted to disassociate our masks from the hospital image. By decorating them with company branding and designs provided by customers.” This is where the Mimaki JV300 wide-format printer comes in.

• Metallic sheen and concealed safety

Net-like structures, metallic sheen, concealed safety, naturally-warming fabrics with Nilit® Heat yarn made of coffee charcoal and PFC-free bio technologies based on renewable raw materials are just some of the highlights of the Schoeller 2019/20 Winter Collection, developed and produced amidst the mountains of Switzerland. Color effects create metallic surfaces on functional textiles and exciting multi-colored looks with richly contrasting reverses.

METALLIC SHINE

The new schoeller®-spirit qualities provide grand style in winter 2019/20. The softly-flowing warp-knitted goods play with transparency and metallic looks. In forest green, silver or copper and aluminized reverse, this season’s  showpieces are also reflective. This play with light continues in the crosswise elastic lightweight with a reflecting dot design. This cool print with concealed safety in two-tone silver grey or khaki green ensures outstanding visibility at twilight. Additional water repellence is provided by the fluorocarbon-free ecorepel® Bio technology, based on renewable raw materials.

WARM FABRICS

The new schoeller®-dryskin qualities ensure a pleasantly warm body climate in winter 2019/20. Thanks to the insulating Nilit® Heat yarn on the interior, which captures and stores the body’s own heat, these fabrics warm the wearer naturally. This unique yarn produced using coffee charcoal posseses antibacterial properties and offers maximum clothing comfort at winter temperatures. The focused pants and jacket qualities in a variety of weights in fresh mandarin, deep aubergine, petrol or light stone also impress with their high abrasion resistance, ideal moisture management and reliable water repellence thanks to PFC-free ecorepel® Bio technology. The same natural heat retention is offered by the cozy schoeller®-naturetec in washable, mulesing-free wool and ecorepel® Bio in dark petrol, navy or rust.

MULTI COLOR

In addition to sustainable fabrics and technologies, winter 2019/20 is dominated by multi-coloration. The highly-elastic multi-colored schoeller®-prestige and schoeller®-dryskinqualities lead to completely new color effects and nuances. Ever-changing, exciting effects result from beautiful mossy greens and dark blue and grey variations to burnt henna and chocolate color combinations. Always with a contrasting color on the reverse, they are real eye-catchers which of course also impress in functional terms. In addition, the schoeller®-dryskin qualities are finished with the PFC-free ecorepel® Bio technology.
