From the Sector

Under its Baldwin brand, BW Converting will partner with Fi-Tech, Inc. at Techtextil North America to demonstrate its TexCoat™ G4 precision spray finishing system, an advanced, sustainable solution designed to reduce chemical waste, minimize water usage and cut energy consumption in textile manufacturing.
Held May 6-8 in Atlanta, Techtextil North America is the premier event for technical textiles and nonwovens in the United States. BW Converting will be present in the Fi-Tech booth A3207 to connect with textile professionals seeking to streamline operations while improving finishing quality and sustainability outcomes.
 
The TexCoat G4 applies chemistry with pinpoint accuracy — on one or both sides of the fabric — with no contamination, overspray or dilution. By eliminating pad baths and reducing the frequency of changeovers, the system significantly improves operational efficiency.
 
Also featured at Techtextil North America will be BW Converting's Baldwin Plasma Pure surface modification technology. Plasma Pure boosts adhesion and uptake in dyeing, coating and laminating processes by optimizing surface energy at the molecular level, without the need for added chemicals.

Demand for high performance solutions for bottle-to-bottle recycling is increasing worldwide. In view of this trend, the specifications for PET recycling machines to handle higher capacities are also growing. With VACUREMA® technology, EREMA offers a system that enables throughputs of up to six tonnes per hour.

"While the bottle-to-bottle market initially tended towards 3-tonne machines, over the past three years we have been seeing increasing demand for PET recycling solutions with throughputs in excess of three tonnes per hour," says Christoph Wöss, Business Development Manager for the Bottle segment at EREMA. In total, a dozen VACUREMA® machines with throughput capacities of four to six tonnes have been installed and commissioned worldwide since 2020. "Together, these large recycling machines produce almost 350,000 tonnes of rPET per year, which is a clear sign that this order of magnitude is now commonplace in the industry," adds Christoph Wöss.

With VACUREMA® technology, EREMA offers a proven system for throughputs between 600 and 6000 kilograms per hour. This technology achieves impressively efficient decontamination and gentle IV treatment and fulfils the strict requirements of the European and North American food safety authorities. Even the basic version produces food-grade rPET, providing the basis for a wide range of end applications. Whether the pellets are then used with SSP for IV adjustment for bottle-to-bottle or high IV applications, an additional upstream vacuum treatment enables direct connection to preform production, or the material is processed inline into sheets or fibres, the VACUREMA® is a versatile all-rounder with food-grade certification.

Advanced VACUNITE® technology for the highest rPET quality
Applications with especially high material quality requirements are covered by advanced VACUNITE® technology. It combines the proven VACUREMA® system with integrated vacuum-assisted SSP in a nitrogen atmosphere. This combination further optimises the material properties and significantly reduces the yellowing of the pellets, which is an important quality factor in bottle-to-bottle recycling. What is more, the closed nitrogen cycle and optimised process control ensure even lower nitrogen consumption, and ultimately, a particularly efficient and environmentally friendly process. VACUNITE® technology is available on machines for throughputs of up to 2500 kilograms per hour that feature particularly low energy consumption and a compact design.

Monforts has completed the installation of a Baldwin TexCoat™ G4 digital spray unit at its Advanced Technology Center (ATC) in Mönchengladbach, Germany.

It has been successfully integrated into one of the two full-size Montex stenter lines at the ATC and is now available for full customer trials, especially for making full use of the latest advanced sustainable finishing chemistries supplied by Archroma.

BW Converting’s TexCoat G4 enables softeners, antimicrobials, durable water repellents, flame retardants and many other water-based chemicals to be precisely applied to textile surfaces, and in combination with industry-leading Montex stenters can reduce water, chemistry and energy consumption by up to 50% compared to traditional pad application processes.

Monforts is providing vital support to dyeing and finishing manufacturers in their development projects, successfully boosting the quality and performance of many new finished products while at the same time maximising productivity and resource utilisation

“Our ATC houses two full Montex stenter finishing lines engineered to accommodate an extremely diverse range of processes, in addition to a Thermex range for the continuous dyeing of denim and other woven fabrics, a full color kitchen and a number of lab-scale systems for smaller batch trials,” says Monforts Head of Sales for South-East Asia Hans Wroblowski. “It enables our customers to test their own textiles and technical fabrics under fully confidential, real production conditions and using the results from these trials we are also able to make recommendations for improving many fabric finishes.

“The new TexCoat installation will make an important contribution to what we can achieve and we are excited to be working together with Archroma and Baldwin to bring further transformative change to the dyeing and finishing space.”

“This partnership is already creating a buzz in the industry and we have several textile manufacturers lining up to take advantage of running production trials at the ATC,” adds Rick Stanford, vice-president of global business development for textiles at BW Converting. “Together we are in a position as never before to accelerate the pace of transformative change in the dyeing and finishing space that will result in significantly lower energy, chemicals and water consumption with increased productivity and higher quality.”

“With the extension of our long-standing partnership with Baldwin – now including the processing expertise and knowhow of Monforts – the development of new concepts for chemical functionalisation and coloration will be taken a step further,” says Michael Schuhmann, Global Market Segment Manager for Technical Textiles at Archroma Textile Effects. “Additionally, we can now demonstrate potential savings and performance levels under actual industrial conditions, providing mill partners with clear proof of efficiency without disrupting their production.”

A collaboration that unites Monforts’ dyeing and finishing equipment, BW Converting’s Baldwin TexCoat G4™ digital spray technology and Archroma’s chemistries towards sustainable solutions is charting the course for the future of sustainable textile finishing.

Together, the three companies will support dyeing and finishing manufacturers, a critical part of the textile supply chain, in their development projects, boosting the quality and performance of their finished products, while at the same time maximizing the productivity and resource utilization of the finishing application process.  

Kicking off the partnership in the second half of this year, Monforts will install BW Converting’s full-width Baldwin TexCoat digital spray unit on a stenter frame at its Advanced Technology Center (ATC) at its headquarters in Mönchengladbach, Germany.

“Our ATC already houses two full Montex stenter finishing lines engineered to accommodate an extremely diverse range of processes, in addition to a Thermex range for the continuous dyeing of denim and other woven fabrics, a full color kitchen and a number of lab-scale systems for smaller batch trials,” explained Monforts Junior Technologist Saskia Kuhlen. “It enables our customers to test their own textiles and technical fabrics under fully confidential, real production conditions and using the results from these trials we are also able to make recommendations for improving many fabric finishes. The new TexCoat installation will make an important contribution to what we can achieve.”
 
TexCoat G4 revolutionizes the traditional water- and energy-intensive pad-dry-cure finishing process by precisely applying chemistry including softeners, antimicrobials, durable water repellents, flame retardants, resins and most other water-based chemicals across the textile surface only where it is required, on one or both sides of the fabric. The system can therefore reduce water, chemistry and energy consumption by up to 50% compared to traditional pad application processes.

The TexCoat G4 installation brings together the surface functions, fabric transport and thermal processing technology of Monforts stenter frames with Archroma’s specialty chemicals, applied with TexCoat’s contactless precision, to achieve optimum absorption and maximum efficacy, exceeding the performance of traditional pad applications.

“Archroma’s commitment to advancing sustainability solutions for technical textiles has led to a pivotal partnership with Baldwin, where the benefits of contactless precision spray combined with our innovative solutions have helped textile manufacturers achieve greater energy and water savings,” said Michael Schuhmann, Global Marketing Segment Manager for Technical Textiles, Archroma Textile Effects. “We are thrilled to take the partnership to the next level with the integration of a renowned equipment expert. Together, we will bring the best of our expertise in sustainable technologies to our customers around the world.”

“Baldwin has enjoyed a great relationship with Monforts and Archroma over the last few years,” added Rick Stanford, Baldwin’s Vice-President of Business Development for Textiles “Individually, we are working hard to assist our customers to achieve their sustainability and environmental targets but this is the first time the three companies have committed to working together with a focus on bringing transformative change to the dyeing and finishing space. It will result in significantly lower energy, chemical and water consumption with increased productivity and higher quality.  We strongly believe that this partnership will be greater than the sum of its parts.”

Beyond textile finishing, Monforts, Baldwin and Archroma will work together to develop a versatile offering that will include coloration concepts and in the not-too-distant future the partners additionally plan to expand their collaboration to continuous spray dye applications developed by Baldwin.

DyStar has published its Integrated Sustainability Report for FY2023/24. For the past 14 years, DyStar has formally reported on its sustainability performance in accordance with the Global Reporting Initiative (GRI) Standards. This report also adopts the Integrated Reporting <IR> framework, which outlines the company's environmental, social, and governance (ESG) practices through the lens of six major capitals.

DyStar has demonstrated the effectiveness of its strategy in the latest report. For instance, their efforts in implementing energy-efficient initiatives across its operations have started to yield credible results. DyStar’s Scope 1 and Scope 2 emissions totaled 42,084 tCO2e, representing a 67% decrease from 2011’s baseline year and a 26% decrease compared to FY2022. Scope 3 accounted for 8.2% of DyStar’s total emissions profile, with over 80% primarily stemming from the transportation of goods and services.

In terms of energy management, the Group has increased its use of renewable energy by 20%. Additionally, several energy conservation initiatives have been implemented as part of a concerted effort to reduce energy consumption globally.

Operationally, there have been several improvements to procedures aimed at boosting water efficiency and achieving cost savings at all manufacturing sites.

Wastewater discharge was reduced by 37%, improving the intensity level to 8.04 m³ per ton of production compared to 8.71 m³ per ton the previous year. This improvement is also partially due to some of their sites operating under a “Zero Liquid Discharge Scheme” mandated by local authorities.

Key highlights of FY2023 include:

• Participated at ITMA Milan, where DyStar introduced a new range of bio-based DyStar products, dyes and auxiliaries containing renewable feedstock, as well as the Eco-Advanced Indigo Dyeing process.

• Celebrating diversity and inclusivity through global campaigns.

CARBIOS and FCC Environment UK, a recycling and waste management companies in the UK, have signed a Letter of Intent (LOI) to jointly study the implementation of a UK-based plant using CARBIOS’ PET biorecycling licensed technology.  CARBIOS’ biorecycling technology is key to supporting FCC’s continuing goal of contributing to the circular economy by exploring new processes and technologies to produce recycled PET (r-PET) from PET plastic and textiles. For CARBIOS, this LOI confirms interest from the waste management sector, in addition to plastic producers, and would mean a foothold for its technology in the UK.

FCC’s continuing contribution to the UK circular economy
Recycling has plateaued in the UK in recent years, but UK Government policy very much supports a continual move to a more circular economy which FCC Environment supports. Achieving a circular economy however requires innovation and investment to deliver real environmental change. Exploring biorecycling is one way of doing this, so FCC is keen to understand this technology better by seeking an evidence based view on the advantages of using enzymes for the treatment of PET such as lower energy consumption and better circularity of the polymers back into the PET production lines. The depolymerization process developed by CARBIOS also facilitates the recycling of all kinds of PET waste, including problematic fractions such as polyester textiles, into high-quality recycled PET.

UK PET biorecycling plant would process hard-to-recycle waste
In order to tackle the plastic waste crisis, CARBIOS has developed a enzymatic depolymerization technology that enables efficient and solvent-free recycling of PET plastic and textile waste into virgin-like products. CARBIOS has ambitious plans to become a leading technology provider in the recycling of PET by 2035. In addition to the world’s first industrial-scale enzymatic PET recycling plant which is currently under construction in Longlaville, France, this UK-based plant would process PET waste that is currently not recyclable using conventional recycling technologies, such as colored, multilayered or textile waste.

The Paris 2024 Summer Olympic Games are just around the corner and a global sports frenzy is underway. However, intense summer workouts often lead to sportswear absorbing excessive sweat, becoming clingy and cumbersome, causing discomfort and potentially impacting performance. A research team from the School of Fashion and Textiles at The Hong Kong Polytechnic University (PolyU) has developed the iActive™ sportswear range which features a root-like liquid transport system and a skin-like active perspiration dissipater and utilises nature-inspired, anti-heat textile fabrics to expedite sweat removal, effectively reducing the weight and stickiness of activewear caused by sweat accumulation during exercise.

The human body has millions of sweat glands that are vital for regulating body temperature by dissipating sweat for evaporation to cool the skin’s surface. With unabating greenhouse gas emissions, the number of very hot days annually is expected to increase significantly. This will lead to elevated energy consumption and increased sweating during physical activity and outdoor labour. Even when wearing highly breathable clothes with good sweat-wicking properties, individuals may still experience discomfort due to excessive sweat accumulation.

A research team led by Dr SHOU Dahua, Limin Endowed Young Scholar in Advanced Textiles Technologies and Associate Professor of the School of Fashion and Textiles at PolyU, has invented the iActive™, intelligent, electrically activated sportswear with a nature-inspired active perspiration function.

Its nature-inspired technologies, including low-voltage-driven artificial “sweat glands” created by skin-like anti-heat textile fabrics and a root-like branching liquid transport system that aligns with the body’s sweat map, can actively and programmably remove sweat to a perspiration dissipater at the lower region of the sportswear. The all-textile sweat dissipater is compact and operates at a safe output voltage of approximately 5-9V, and its battery is easy to detach from the clothing, making it convenient for users to repeatedly wash the clothing by hand or in a washing machine to maintain hygiene. When the human body’s sweat rate is low, iActive™ can still be used independently without the battery.

Based on the optimised wettability pattern and gradient, the research team utilises a skin-like textile fabric to transport sweat one-way quickly and dissipate it from the inside to the outside. This feature reduces the stickiness and weight of clothing, improves breathability and ensures the garments remain dry and comfortable to wear. Experimental findings indicate that iActive™ creates a breathable and dry skin microclimate by dissipating sweat at a rate that is three times faster than the maximum human sweating rate. This innovation can also prevent discomfort from coldness and moisture after a workout. In comparison to traditional fabrics, the textile materials in iActive™ are 60% lighter and 50% less clingy when soaked, providing the wearer with all-round comfort and enabling sports enthusiasts and athletes to perform at their best.

Furthermore, a mobile app further aids personalised sweat management by wirelessly adjusting the sweat level of iActive™. This innovation is versatile and can be seamlessly integrated into a variety of textile materials to facilitate sustainable mass production. Beyond sportswear, iActive™ is also well-suited to protective clothing and workwear for individuals engaged in prolonged, high-intensity physical labour and outdoor occupations, including healthcare professionals, construction workers, firefighters, law enforcement officers and others, thereby significantly enhancing their work performance.

Dr Shou Dahua stated, “The extreme weather and high temperatures resulting from global warming have elevated the importance of heatstroke prevention and cooling measures on a global scale. Drawing on the vivid phenomena of thermal insulation and directed liquid flow in nature, we aim to foster innovation and sustainable advancement in garment manufacturing by inventing intelligent clothing and materials to address global challenges. We seek to harness the power of technology to infuse fresh perspectives into the traditional clothing industry, thereby enhancing its competitiveness.”

His research team has also developed a premium fabric named Omni-Cool-Dry™, drawing inspiration from volcano dwelling beetles. This fabric not only provides ultra-fast sweat dissipation and ensures all-day comfort with its dry and breathable features under dynamic thermal conditions, but also reflects solar radiation and emits body heat into the cold universe, enabling passive cooling. The team is working hard to leverage the benefits of both inventions to further enhance the sweat-dissipating and cooling capability of iActive™ sportswear.

Dr Shou Dahua, a core member of the PolyU Research Institute for Intelligent Wearable Systems and the Research Centre of Textiles for Future Fashion, has recently been bestowed with the 2023 Distinguished Achievement Award by The Fiber Society for his outstanding contributions to the fields of personal thermal and moisture management, intelligent wearables and soft robotics. The accolade is presented annually to an individual researcher worldwide. He has also received international innovation awards, including consecutive TechConnect Global Innovation Awards in 2021 and 2022. Moreover, his research papers have been published in various internationally renowned academic journals including Science Advances, PNAS, Advanced Functional Materials, and Advanced Energy Materials. Dr Shou will be chairing The Fiber Society Spring 2025 Conference at PolyU.

Mayer & Cie. presented an overview of its current portfolio in the circular knitting sector at the ITM in Istanbul. Two machine types – the SF4 3.2 III and the Relanit 3.2 HS II – and various smart solutions that make circular knitting more efficient were on display. knithawk, a tool for the optical detection of knitting defects, met with interest among the visitors. The same was true for knitlink, Mayer & Cie's hub for digital solutions. Spare parts packages and conversion kits are also in demand for the long-term value retention of Mayer & Cie. machines.

Relanit 3.2 HS II
The Relanit 3.2 HS mechanical single jersey machine offers high productivity, especially in the context of elastic plating. It processes a wide range of yarns and qualities reliably. It is suitable for processing recycled yarns. Their energy consumption is up to a third lower than that of a circular knitting machine with conventional technology.

In Istanbul, Mayer & Cie. presented an updated version of its flagship, the Relanit 3.2 HS II. The new open-width take down is the single component that attracted the most interest. It ensures a uniform pull-off tension of the knitted fabric over its entire circumference. The knitted hose is only opened below the take-down rollers. Furthermore, the take-dwon is equipped with two drives: one for tensioning, one for rewinding. Both can be controlled separately.

Another innovation of the Relanit 3.2 HS is aimed at reducing downtimes: The needle with predetermined breaking point, which was developed together with Groz-Beckert, prevents it from breaking uncontrollably and, in the worst case, breaking needle butt. The new spring sinker is also a joint development with Groz-Beckert. This makes the Relanit 3.2 HS II run more smoothly, produce less noise as well as with less wear and tear.

SF4-3.2 III for lightweight three-tread fleece knitted fabrics
With its SF4-3.2 III, Mayer & Cie. is addressing a trend in the clothing industry that is reflected beyond Turkey: lightweight, elastic three-thread knitted fabrics in both pure cotton and blends.

New Control 5.0 machine control system
Both ITM machine exhibits were on display with the new Control 5.0 machine control system. Control 5.0 is a prerequisite for using knitlink, the hub for Mayer & Cie's digital applications. In this function, the machine control system attracted interest from various large customers.

In the standard SmartControl version, as shown in Istanbul, a so-called Smart Knob is attached to each machine foot. From there, all the functions that the machine operator needs for his work are available. More in-depth settings, such as those made by the knitting manager, are only possible from a mobile device. Any number of Mayer & Cie. machines can be operated from this at the same time.

knithawk
knithawk, a tool for optical defect detection, inspects the knitted fabric as it is produced. It sits in the single jersey machine directly at the knitting point. If knithawk detects a serious or recurring error, the machine is stopped. The tool also creates an error log.

Machine-specific upgrade and conversion kits
With its upgrade kits, Mayer & Cie. brings technological innovations to existing machines. These range from machine-specific upgrades, such as the Performance Kit for existing Relanit 3.2 models to the Senso Blue RS lubrication system.

In addition to the upgrade kits, Mayer & Cie. offers conversion kits for popular machine types. Two are currently available: for the MV4 3.2 II/MBF 3.2 and the S4-3.2 II/ SF4-3.2 III.

Lightweight design is a key enabler for addressing the energy transition and sustainable economy. Following the liquidation of the state agency Leichtbau BW GmbH, a consortium consisting of the Allianz Faserbasierter Werkstoffe Baden-Württtemberg (AFBW), the Leichtbauzentrum Baden-Württemberg (LBZ e.V. -BW) and Composites United Baden-Württemberg (CU BW) now represents the interests of the lightweight construction community in the State.

The Lightweight Design Agency for Baden-Württemberg is set up for this purpose on behalf of and with the support of the State. The Lightweight Construction Alliance BW is the central point of contact for all players in the field of lightweight construction in the State and acts in their interests at national and international level. Professor Markus Milwich from the German Institutes of Textile and Fiber Research Denkendorf (DITF) represents the agency.

The use of lightweight materials in combination with new production technologies will significantly reduce energy consumption in transportation, the manufacturing industry and the construction sector. Resources can be saved through the use of new materials. As a cross-functional technology, lightweight construction covers entire value chain from production and use to recycling and reuse.

The aim of the state government is to establish Baden-Württemberg as a leading provider of innovative lightweight construction technologies in order to strengthen the local economy and secure high-quality jobs.

Among others, the "Lightweight Construction Alliance Baden-Württemberg" will continue the nationally renowned "Lightweight Construction Day", which acts as an important source of inspiration for a wide range of lightweight construction topics among business and scientific community.

Professor Milwich, an expert with many years of experience and an excellent network beyond the State's borders, has been recruited for this task. In his role, Milwich also represents the state of Baden-Württemberg on the Strategy Advisory Board of the Lightweight Construction Initiative of the Federal Ministry for Economic Affairs and Climate Action, which supports the cross functional-technology and efficient transfer of knowledge between the various nationwide players in lightweight construction and serves as a central point of contact for entrepreneurs nationwide for all relevant questions.

From 2005 to 2020, Professor Milwich headed the Composite Technology research at the DITF, which was integrated into the Competence Center Polymers and Fiber Composites in 2020. He is also an honorary professor at Reutlingen University, where he teaches hybrid materials and composites. "Lightweight design is an essential aspect for sustainability, environmental and resource conservation. I always showcase this in research and teaching and now also as a representative of the lightweight construction community in Baden-Württemberg," emphasizes Professor Milwich.

Autoneum’s sustainable, textile and lightweight Propylat technology reduces both interior and exterior noise of vehicles. Propylat was originally developed by Borgers Automotive, which was acquired by Autoneum in April 2023. The versatile technology is characterized by a flexible material composition of natural and synthetic fibers with a high recycled content and contributes to significant waste reduction thanks to its complete vertical integration. In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

The ongoing electrification of mobility as well as increasingly strict regulatory requirements for vehicle performance in terms of sustainability and acoustics are presenting new challenges to car manufacturers worldwide. With Propylat, Autoneum now offers another lightweight, fiber-based and versatile technology whose sound-insulating and -absorbing properties as well as high content of recycled materials help customers address these challenges. Propylat-based products not only contribute to reducing pass-by noise and improving driver comfort, but they are also up to 50 percent lighter than equivalent plastic alternatives; this results in a lower vehicle weight and, consequently, less fuel and energy consumption as well as lower CO2 emissions.

Autoneum's innovative Propylat technology consists of a mixture of recycled synthetic and natural fibers – the latter include cotton, jute, flax or hemp, for example – that are consolidated using thermoplastic binding fibers without adding any further chemical binders. Thanks to the flexible fiber composition and the variable density and thickness of the porous material, the properties of the respective Propylat variant, for example with regards to acoustic performance, can be tailored to individual customer requirements. This allows for a versatile application of the technology in a variety of interior and exterior components such as wheelhouse outer liners, trunk trim, underbody systems and carpets. For instance, Propylat-based wheelhouse outer liners significantly reduce rolling noise both inside and outside the vehicle while at the same time offering optimum protection against stone chipping and spray water.

In terms of sustainability, Propylat always contains a high proportion of recycled fibers – up to 100% in some variants – and can be manufactured with zero waste. Thanks to the full vertical integration of Propylat and Autoneum’s extensive expertise in recycling processes, the technology also contributes to a further significant reduction in production waste. Moreover, the Propylat PET technology variant, which consists of 100% PET, of which up to 70% are recycled fibers, is fully recyclable at the end of product life. For this reason, Propylat PET has been selected for Autoneum Pure – the Company’s sustainability label for technologies with excellent environmental performance throughout the product life cycle – where it will replace the current Mono-Liner technology going forward.

Propylat-based components are currently available in Europe, North America and China.
