From the Sector

Digitalization is a big story in the world of business. It’s all about change, making use of technology to transform attitudes and create new opportunities to grow revenue. At its heart is innovation, with new systems and intelligent use of data. In textiles, the entire value chain is going digital, as evidenced by the commitment of Swiss Textile Machinery Association member firms. Their story – presented here in six ‘chapters’ – spans industry sectors through spinning, weaving, finishing and nonwovens.

Cost savings and more
The process of digitalization in the textile industry today is continuous – faster in some segments than others – but noticeable everywhere. Automation is promising in many areas of finishing and making-up, where initial investments are being made. An example is folding of finished goods, previously a slow manual operation. Now, high-performance automatic folding machines from Swiss company Espritech deliver the potential for cost savings, unlocking new options for positive change at this most labor-intensive stage of production. For manufacturers in low-cost areas, the benefit results from its volume and is a simple financial one. In higher-cost segments, the application of this technology can be part of a completely new business model, taking production closer to the end customer.

Better process, better workplace
Pioneering in the field of digitalization embraces social responsibility along with the introduction of bold new technological innovation. That’s a commitment made by Uster, as it aims to shape future working practices in the textile industry in areas where its systems are applied. In fabric inspection, that means combining the strengths of human capabilities with the performance of Artificial Intelligence. Automatic defect classification with machine learning technology is the next leap in digitalization for fabric manufacturers, following on from automated detection of fabric faults, which is already well established in weaving and finishing mills. This will bring benefits in profitability for the manufacturer – as well as an improved working environment for their operatives, freed from repetitive tasks.

Information, flexible and fast
Access to data is critical in the digitalized world of textiles. It must be flexible, fast and secure, and available to all levels of the company – worldwide. Jakob Muller serves the narrow fabrics industry ideally with a digitalization portal, perfectly developed to provide essential production information. The portal is a browser-based production data acquisition system, with direct access to the machine controls. The system offers unique data monitoring and communication on a global framework. Digitized weave rooms present information 24/7 on desktops at the customer’s plant, as well as on tablets and smartphones remotely.

Making the most of it
Rieter takes advantage of latest digital technology to offer customers a unique experience. Their digital spinning suite helps spinners overcome their daily challenges and manage costs and efficiency more effectively. This all-in-one mill management system connects all the machinery, giving quick access to the right information and a holistic view, from bale to yarn. Users profit from full transparency, and are presented with recommendations based on long-standing experience and know-how. This is digitalization at its most practical, applied to allow spinners to make the most of their installed machinery.

Production, service, training – digital everything
As a solutions provider, Saurer puts digitalization at the core of business, integral to its technology offering to customers. Some latest examples include self-optimization of spinning machines, and a fully automated transport of cylindrical or conical cross-wound packages. These are automatically stored in an internal buffer system, for later feeding to subsequent processes. Of course after-sales service is also digital: the e-shop and machine information hub, together with the web-based training centre, ensure that knowledge is transferred to customers – turning employees into experts.

See the future system today
Autefa Solutions uses the concept of digital twinning, visualizing any real-world concept of a nonwovens line to make it easier for potential customers to grasp the idea. It’s also a big help for training and servicing needs. Most of all they digitalize important parts e.g. of a baling press line with perfectly interconnecting software tools. This is an excellent method for reducing commissioning times. Ordered bale presses reach technical readiness in the form of a digital twin, before they are commissioned in the real world. This typically halves the total time to get the line up and running.
Speaking on behalf of Swiss Textile Machinery Association members, André Imhof, CEO of Autefa Solutions Switzerland AG, says: “Making digitalization our friend opens doors for business model innovations, which is essential for our industry competitiveness. The approach is to digitalize everything that can be digitalized. We won’t stop.”

Swiss cutting system manufacturer Zünd Systemtechnik and Dutch composite automation company Airborne have expanded their collaboration. As a result of a new distribution agreement, customers will be able to benefit from state-of-the-art digital production solutions for automated processing of composite materials. Zünd and Airborne will jointly promote these production solutions through their sales and servicing networks.

Both companies are technology leaders offering solutions for composites manufacturing and processing – Zünd develops and manufactures digital flatbed cutting systems capable of processing reinforced fiber materials such as CFRP or GRP. Airborne, based in Den Haag in the Netherlands, provides fully integrated automation solutions for efficient composites processing.
 
The goal of this partnership is to make it easier than ever for customers to access state-of-the-art digital cutting and automation solutions. In that endeavor, the competencies of both companies complement each other perfectly. Their combined expertise manifests itself especially in the areas of fully automated cutting, preforming, offloading and sorting.

Airborne’s automated kitting solutions reduce operating costs by maximizing material yield through optimized nesting. At the same time, they resolve the challenges inherent in sorting and grouping cut parts from complex nested layouts into laminate-ready kits with minimal operator intervention. Airborne offer a portfolio of solutions tailored to meet the individual needs of customers from affordable entry-level semi-automated products through to fully integrated and high productivity systems. All systems are "plug and play" and require no additional special programming. Airborne’s software generates the required robotics code directly from information derived from the nesting data and permits static or dynamic nesting and a sorting solution that adapts “on the fly”.

Zünd has been designing, manufacturing, and marketing digital cutting systems for more than 30 years. Zünd high-performance modular cutters are now in use all over the world. The Swiss family-owned company now in its second generation has established a global network of Zünd sales and service organizations under the leadership of Oliver Zünd. “This is a situation where two strong partners complement each other in much the same way as in strong partnerships we have established in other industries. It is a continuation of a long-standing company strategy. Airborne has excellent know-how in developing and manufacturing automated solutions for processing composites. Together we can offer our customers state-of-the-art technology and provide a technological answer to the growing demand for high-performance, innovative production systems in the composites market."

Joe Summers, Commercial Director for Airborne agrees: "Our partnership with Zünd brings a great deal of added value to our customers. Zünd shares our goal of creating greater cutting-room productivity. The Zünd cutter is key to converting materials with the greatest possible efficiency and maximum material usage."

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, joined forces to launch an eco-advanced alternative to the denim fabric washing process, including in some cases the mercerization, one of the most water-intensive and pollutant processes of denim fabric finishing.

It all starts with the spinning step where the cotton is turned into yarn. The second step is a pretreatment that will prepare the yarn for the dyeing step. The dyed yarn then goes through the sizing process, which is a treatment preparing it for weaving. At this stage, we have obtained a denim fabric that will go through a few more steps. First, the fabric may undergo a washing treatment or, in some cases, mercerizing treatment which consists of treating it with caustic soda in order to obtain a more lustrous, flat and less reddish blue and black denim.

In both traditional ways to clean the fabric, washing or mercerizing, multiple highly water intensive washings are required in order to restore optimal fabric pH and remove unfixed dyestuff and any undesired deposits or impurities from the fabric. One of such impurities released in the washing process is aniline, a substance that is classified as a category 2 carcinogen and considered toxic to aquatic life.

That is why Archroma and Jeanologia decided to team up and develop an alternative to the traditional fabric cleaning process and its subsequent water-intensive and water-polluting washings.

• The breakthrough alternative to the fabric cleaning concept presented by Jeanologia and Archroma combines the use of the aniline-free* PURE INDIGO ICON dyeing system of Archroma, and the water-free** and chemical-free “G2 Dynamic“ finishing technology of Jeanologia.
• The Archroma/Jeanologia solution allows to create aniline-free* denim, and improve the final aspect of the fabric through a fully chemical-free and almost water-free** cleaning alternative treatment.
• The Archroma/Jeanologia solution can also be used with additional Archroma coloration systems such as INDIGO REFLECTION or PURE UNDERTONES.

Umberto Devita, Business Development Manager at Archroma’s Competence Center for Denim & Casual Wear, who was the project leader for this new development, comments: “At Archroma, we strive to develop solutions in line with our principles of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it’s our nature”. It was therefore very inspiring to work with a partner who shares the same values of developing efficient new processes to bring all know-how to our customers to maximize value – for denim that looks as good as the good it creates.”

For Jean-Pierre Inchauspe, Business Director of G2 Dynamic at Jeanologia, “this association is another step to change traditional, more polluting and water consuming processes in the textile industry for new ones using technology, improving, and boosting subsequent production stages up to the finishing of the garment, making them more efficient and allowing companies to be more competitive, increase productivity and offer a product that is completely sustainable with high quality.”

Comber machines from Trützschler are already trusted by customers across the textiles industry and around the globe. The TCO 21 is the latest addition to their portfolio and was built to boost productivity,  ensure quality and support increased automation.

High productivity and raw material savings
One of the key benefits of the TCO 21 is its advanced processing speed. This next-generation combing machine is able to produce at a rate of up to 600 nips per minute. the TCO 21 can also be coordinated with Trützschler’s JUMBO CANS (Ø 1.200 mm). They not only reduce yarn defects due to fewer piecings which leads to quality improvements, but also offer a higher efficiency because of their larger dimensions. This, for example, has positive effects on the number of necessary cans and can transports – and results in lower personnel costs.

Excellent yarn quality
The TCO 21 comes with COUNT MONITORING as standard. This feature makes it possible for the machine operator to define limits for count variations via an easy-to-use display. Trützschler’s DISC MONITOR system of sensors measures the count continuously, and the machine alerts the operator and switches off if the limit is exceeded. In addition, the COUNT MONITORING function also includes spectrogram analysis.

Customers can further strengthen their focus on quality by choosing to add the COUNT CONTROL function to the TCO 21. It is managed via the same easy-to-use display, and offers automatic sliver count measurement, as well as spectrogram analysis. It also automatically regulates the main draft during production to balance count variations and ensure the desired sliver count. This feature is particularly attractive for customers who manufacture blends of cotton and synthetic, as it can also be used to avoid variations in the overall yarn composition.

Automatic optimization
The TCO 21 joins the TCO 12 from Trützschler as an combing machine that offers automatic PIECING OPTIMIZER technology, and that finds the right piecing setting without a single laboratory test, because of two functions: First by adjusting the piecing time in the combing cycle (timing function). Whereas the resetting of the detaching point (piecing time) is usually a very time-consuming task, it now takes only a few minutes and is performed automatically at a push on a button. Second the customer is helped to select specific detaching curve types (curve function) for their unique requirements.

Easy operation
The TCO 21 is simple to operate and maintain. The SMART TOUCH display is fast and intuitive, and a Radio-Frequency Identification (RFID) sensor quickly identifies each user and adapts the information on the display to their individual needs. The multi-colored T-LED display provides visual indications of the machine’s status or quality parameters over large distances which enables the operator recognizing them at a glance in the entire spinning mill. The TCO 21 is built with original Trützschler electronics that ensure high performance and durability: Their intelligent cooling system, that has already proven itself in the draw frame TD 10, contributes to a longer service life by reducing the operating temperature of electronic power components. Even if components have to be replaced at some point, the customer can keep their spare parts inventory small, because they can switch also electronics spare parts flexibly between different machine types, e.g. cards and draw frames. The option to add an automatic greasing function completes the easy operation of the TCO 21.

US Vice President Kamala Harris announced significant multimillion-dollar investments by Parkdale Mills and six other companies today, as part of the Administration’s Call to Action to the private sector to promote economic opportunity in the region, as her office works to address the root causes of migration.

Vice President Harris, who is overseeing diplomatic efforts with El Salvador, Guatemala, Honduras, and Mexico, announced several private sector commitments to strengthen economic opportunities in the Northern Triangle and made remarks at a White House roundtable, which included Anderson Warlick, Chairman and CEO of Parkdale Mills. The textile and apparel co-production chain is one of the most essential supply chains for employment and economic development in both the United States and the Northern Triangle region, currently supporting over 1 million jobs in the United States and the Central American region. The Dominican Republic-Central America Free Trade Agreement (CAFTA-DR) and its strong rules of origin are the primary reasons this co-production chain exists, which is seeing significant growth this year.

North Carolina-headquartered Parkdale Mills, one of the largest manufacturers of spun yarn and cotton consumer products in the world, will make a multimillion-dollar investment in a new yarn spinning facility in Honduras and make an additional substantial investment to support existing operations in Hillsville, Virginia. This investment will help customers shift 1 million pounds of yarn per week away from supply chains in Asia and China and enhance U.S. and CAFTA-DR co-production resilience and increase regional product offerings. Parkdale’s announced investment will create hundreds of jobs in Honduras and further support hundreds of employees in Parkdale’s Hillsville operations.  

Recently, administration officials from the U.S. Trade Representative’s office and the Vice President’s office met with the U.S. textile industry to reaffirm the importance of rules of origin in nearshoring production chains, helping address labor and environmental challenges and mitigating supply chain risk.

“I would like to sincerely thank Vice President Harris for making this announcement and leading the effort with private industry to create more economic opportunities in northern Central America and the United States,” said Anderson Warlick, Chairman and CEO of Parkdale Mills. “Parkdale’s investments will support good paying jobs in the United States and in the Central American region and significantly increase our extensive product offering and capacity, including the production of sustainable specialty yarns.

Parkdale sees an enormous opportunity for brands and retailers to re-shore and nearshore production supply chains and double the size of U.S.-CAFTA-DR trade, because of the rules of origin in our trade agreement and a shift in sourcing by brands and retailers mitigating their supply chain sourcing risks.  We are excited about what this opportunity means for jobs in the U.S. and the region for this critical production chain and couldn’t be more thrilled to be part of this effort.  We look forward to working with the Vice President and her team on strengthening the textile and apparel production chains in the U.S. and region.”

National Council of Textile Organizations (NCTO) President and CEO Kim Glas, said, “This is an exciting and important announcement by Parkdale and Vice President Harris. Our industry has invested billions of dollars in the U.S. and in the region as a result of the investment-based rules of origin in the CAFTA-DR agreement, which ensures the job benefits of the agreement are reserved for the parties to the agreement.  Additional substantial announcements on further investment in textile and apparel production are expected soon.

As brands and retailers are seeking more environmentally sustainable, vertically integrated, transparent, and quick turnaround supply chains, our collective industries stand ready to work with companies that are seeking to mitigate sourcing strategies as Asian supply chains have faced enormous production constraints.  Further verticalization in the industry, like Parkdale’s announcement today, allows broader product diversification and grows jobs across the textile and apparel production chain.

We are thrilled with today’s announcement because it is a win-win for American and Central American workers and our environment and a huge opportunity to further recalibrate supply chains out of China and Asia. This valuable co-production chain between the U.S. and the CAFTA-DR region accounts for $12 billion in two-way trade and billions of dollars of investment. Significant growth is occurring in our sector and is expected to continue as supply chains continue to recalibrate.  We are delighted about this today’s announcement and appreciate the Administration’s strong support.”

Fibre Extrusion Technology, UK is celebrating a successful INDEX20 nonwovens exhibition in Geneva, Switzerland, which closed on 22 October. Although the company has a long history in supplying meltspinning equipment for the nonwovens sector, this represents its first venture at a dedicated nonwovens show.
 
FET’s Managing Director, Richard Slack explains. “Techtextil and ITMA have previously been our main exhibitions of choice, but INDEX20 was an ideal vehicle for FET to launch our new laboratory scale spunbond system, which enables client development of nonwoven fabrics in a number of formats and polymers.”
 
FET already has spunbond systems in the field, including composite systems which utilise both spunbond and meltspun functions. The growth in global nonwovens technology, partly driven by demand for pandemic-related materials, is forecast to continue.
 
“We were delighted with the response at INDEX”, continued Richard Slack. “There was considerable interest shown in the new spunbond system and its potential for lab scale innovation. It’s clear that the industry is seeking new alternatives to synthetics at the moment, and our technology is able to assist with the testing and assessment of many of the new feedstocks being pioneered in this extremely inventive sector, where everyone is suddenly talking and cooperating with everyone else, regardless of whether they are generally competitors. We recorded in excess of 20 serious enquiries from totally new contacts and sectors, including blue chip companies in the hygiene, medical and packaging industries.”
 
“There were initial concerns about projected attendance figures, especially from China and USA companies, but we experienced good footfall from key decision makers, especially those from Europe. It was encouraging to at last experience the opportunity for face-to-face contact with old and new customers on a large scale and we are now starting to reap the benefits with enquiries continuing to flow in”.

Jerker Krabbe of Eton Systems, Semir Paclica of Baldwin Technology and Sven Öquist of Coloreel will contribute a wealth of experience from a wide range of industries to the Swedish Textile Machinery Association.

Jerker Krabbe joined Eton Systems, one of the leaders in intelligent overhead conveyor systems, as CEO six months ago, and has more than 25 years of commercial, operational and international experience within several well-known companies such as Electrolux, Husqvarna, Gunnebo and Assa Abloy, and most recently as CEO of Sector Alarm AB.

Semir Pavlica has a master’s in finance and started his career at the SEB banking group before joining Baldwin Technology five ago. He is now managing the company’s process improvement and performance.

Sven Öquist joined Coloreel as Vice President of Sales in April this year. He has an international background with previous positions as Managing Director/CEO for a number of Swedish companies. He has also led the global sales team at Polestar, the electrified brand of Volvo Cars.

Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic. It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change. Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That are the motives for Trützschler to develop the intelligent card TC 19i, which sets a new benchmark for energy-efficient carding.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.

In a head-to-head comparison between the TC 19i and a high-performance card from a competitor, the TC 19i consumed at least 10 % less energy per kilogram of material produced when manufacturing rotor yarn from a cotton and cotton waste mix. The compared energy values included electric power consumption and energy required for suction and compressed air and were measured in both cards at the same production of 180 kg/h. A 10 % reduction in energy per kilogram of sliver produced, as proven here by TC 19i, can have a significant impact on a spinning mill’s profitability; annual savings worth a five-digit sum are frequently possible, depending on factors such as the output of the mill. The customer trial also showed TC 19i’s excellent reliability at the customer’s usual production rate of 180 kg/h, and even demonstrated stable performance at 300 kg/h in the same application. Because the TC 19i with T-GO gap optimizer realizes maximum production rates at no compromise in quality, manufacturers can reduce their energy demand and investment costs drastically: Less machines are needed to achieve the desired output, and energy consumption per production is reduced.

This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model.

Fibre Extrusion Technology of Leeds, UK has delivered nine meltspinning systems to clients in the biomedical sector since the onset of the Covid-19 pandemic, with a similar number currently on order for 2021/22. This way FET could confirm the position as an acknowledged world leader in meltspinning equipment for the production of precursor materials used in medical devices and as a default supplier for absorbable suture production systems, with orders virtually doubling year on year.

Recent installations include a multi-functional system that can produce both multifilament and monofilament pre-cursor fibres, but nonwoven systems have been particularly prominent, driven by the burgeoning demand for FFP3 masks, gowns and other medical products required during the pandemic. These have been sold to medical device manufacturing companies across the globe, including the Far East, USA and Europe. Research organisations have also invested in FET systems for biomedical applications, the most recent being the University of Leeds in a laboratory scale Spunbond system.

The FET in-house Process Development Laboratory and ongoing collaboration with biomaterial polymer suppliers has helped to optimise the biomedical melt spinning technology. The Laboratory is at the disposal of customers for all aspects of confidential testing and evaluation. To further increase this competitive edge, FET will be opening a new Process Development Laboratory and Visitor Centre in early 2022.

• Achievement Ahead of Schedule

All of Sateri’s five viscose mills in China are now fully compliant with the emission limits set out in the European Union Best Available Techniques Reference Document (EU-BAT BREF) on Polymers, following recent verification of Sateri Jiangsu and Sateri China mills.

Verified by independent consultant Sustainable Textile Solutions (STS), a division of BluWin Limited (UK), the parameters assessed included resource utility efficiency, wastewater discharge and air emission.

Allen Zhang, President of Sateri said, “Sateri Jiangsu was established in 2019 following an acquisition while Sateri China was built in the same year. We had aimed to have both mills meet EU-BAT’s recommended emission levels by 2023. To achieve this two years ahead of schedule underscores our continuous efforts in process improvement and control of pollutant emissions, and resource utilization efficiency. We will continue to pursue manufacturing excellence and invest in best-in-class technologies for all our mills – existing, acquired, and newly constructed ones – as part of our Vision 2030 commitment towards closed-loop and cleaner production.”

Chen Xinwei, Chairman of China Chemical Fiber Industry Association, said, "China's regenerated cellulose fibre industry has been progressing steadily in recent years. As a major viscose manufacturer, Sateri has demonstrated leadership in benchmarking itself against advanced domestic and international standards, focusing on low-carbon development, energy-saving and emission-reduction technology, and cleaner production to advance sustainable development, as well as enhance the company’s competitiveness. All other players in the industry should be encouraged to follow suit."

Sateri is a member of the RGE group of companies; Sateri’s other three mills - Sateri Fujian, Sateri Jiujiang and Sateri China (Jiangxi) - had attained EU-BAT compliance in 2020.
