From the Sector

• Innovation begins with creativity
• A pioneer of the manmade fiber industry

When the manmade fiber age began a century ago, a German company was responsible for the pioneering work involved. Barmag, established in 1922, was one of the world’s first companies to construct machines for the large-scale production of synthetic staple fibers. To this day, the leading manufacturer of manmade fiber spinning systems and texturing machines in Remscheid – a brand under the aegis of the Swiss Oerlikon Group since 2007 – has shaped technological progress in this sector; in future, with ever more innovations focusing on sustainability and digitalization.

Barmer Maschinenfabrik Aktiengesellschaft (Barmag) is founded in Barmen, located in the Bergische Land region, on March 27, 1922. The German and Dutch founders enter unchartered technological territory, one created as the result of a groundbreaking invention: in 1884, French chemist Count Hilaire Bernigaud de Chardonnet used nitrocellulose to produce the first so-called artificial silk, later known as rayon. The following decades see rapid development focusing on the search for synthetic textile fibers and their manufacturing technologies. As one of the first machine factories, Barmag battles its way through the eventful early years of the manmade fiber industry, the ‘Roaring Twenties’ and the Great Depression – and suffers the extensive destruction of its factories at the end of World War Two. Rebuilding is successful. With the unstoppable success story of purely synthetic plastic fibers such as polyamide, the company flourishes from the 1950s through to the 1970s, establishing sites in all international, for the textile industry at the time important, industrial regions and garnering prestige across the globe in the process. In the ups and downs of expansion, global competition and crises, Barmag reaches the very pinnacle of the market and becomes the preferred technological development partner for the manmade fiber industries in China, India and Turkey. The company has been a high-impact brand under the umbrella of the Oerlikon Group since 2007.

On the wings of innovation
Today, Oerlikon Barmag is a leading supplier of manmade fiber filament spinning systems and part of the Manmade Fibers Solutions business unit of the Oerlikon Polymer Processing Solutions Division. And our aspirations have not diminished: “The striving towards innovation and technological leadership has been, is and will always be part of our DNA”, emphasizes Georg Stausberg, CEO of Oerlikon Polymer Processing Solutions. In the past, this has been observable in such trailblazing innovations as the revolutionary WINGS generation of winders for POY in 2007 and WINGS for FDY in 2012. Currently, the focus of new and further developments is very much on digitalization and sustainability. Here, Oerlikon Barmag has – as one of the world’s first systems manufacturers – been implementing fully-networked smart factories for globally-leading polyester manufacturers since the end of the last decade. Within this context, digital solutions and automation are also helping to provide greater climate and environmental compatibility. This sustainability commitment is not only evidenced by the e-save label introduced for all products back in 2004: Oerlikon is endeavoring to also make all its sites carbon-neutral by 2030 and to acquire its energy exclusively from renewable sources. An ambitious target, whose achievement could be helped by the Oerlikon Barmag anniversary, states Georg Stausberg: “Innovation begins with creativity. And remembering the past provides plenty of motivation and inspiration for the future.”

• Mimaki’s Newest Product Series to Transform the Sign Graphics and Textile Markets with Improved Efficiency and Quality 
• Mimaki to launch the 330 Printer Series and the new entry-level cutting plotter series, the CG-AR

Mimaki Europe today announces a brand-new large format inkjet printer series, the 330 Series, including the JV330-160, CJV330-160 and TS330-1600, as well as a new range of CG-AR cutting plotters. Launched during the company’s Global Innovation Days event, the 330 Series leverages Mimaki’s cross-platform strategy, to offer a high-end yet cost effective printing solution across several sectors. Similarly, the CG-AR Series offers users new workflow enhancing, entry-level cutting plotter technologies available in three sizes. Both launches align with Mimaki’s objective to grow both its high-end and entry-level product range, to further encourage and support customers expanding and improving upon their printing services and product offering.

Introducing Mimaki’s latest printers – the 330 Series

Following on from the success of the 100 and 300 Plus Series, the 330 Series was developed to offer mid- to high-end printing models, focusing on high image quality and productivity. As a company renowned for its high-colour range, Mimaki’s newest printers can achieve high resolution, durable prints for both the Sign Graphic and Textile industries. 

The eco-solvent inkjet printers, the JV330-160 and CJV330-160, deliver the high-standard of colour required for indoor and outdoor sign graphics through the new “Deep Color Natural” input profile, offering eye-catching and vivid solid colours, natural skin tones as well as deep reds and neutral greys. With printing speeds of 21.0m2/h during standard mode while using 4 colours, this printer is ideal for print jobs that require quick delivery. The in-built cleaning mechanisms and monitoring features ensure an efficient workflow and allow for longer running times.

Both models feature a newly designed unwinding system that allows three rolls of media to be loaded simultaneously, greatly reducing the time and manpower required to change print media. One operator can bring the desired media into position simply by turning the media changer. Another standard feature is an “XY slitter” - a highly precise cutting technology, which provides in-line X-axis and Y-axis sheet-fed cutting. This eliminates the unwinding and rough cutting from the workflow, helping printers to significantly speed up and streamline the post-process, with less interference needed.

The print-only model JV330-160 as well as the integrated printer and cutter CJV330-160 will be available globally in April 2022.

In addition to the Sign Graphics solutions, Mimaki has also released the TS330-1600, a sublimation transfer inkjet printer, for the textile industry. Enabling both high production and high image quality, and equipped with new functions to improve stable operation, the TS330-1600 can achieve a printing speed of 69m2/h in Draft mode with a 4-colour ink set, with the fastest mode reaching up to 135m2/h. The newest cleaning mechanism applies a cloth wiper that removes unwanted ink from the nozzle surface, reducing ink splatter and improving the overall upkeep of the machine.

Increasing efficiency with entry-level CG-AR plotting cutter series

Alongside the 330 Series, Mimaki has also launched the CG-AR Series plotting cutters. Available in three different sizes (CG-60AR, CG-100AR and CG-130AR), these plotters go above and beyond current entry-level options available today. Recognising customer demand of shorter delivery times, these cutters provide increased speed and accuracy, all with user-friendly operability. In addition, the cutters have the ability to handle a diverse range of materials, such as PVC, fluorescent and reflective sheets.

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 most textiles, finishing processes are not actually the last stage. Products often need an extra touch of expertise to make them perfectly ready for the customer. At this point in the value chain, that usually means manual tasks – but now there are technical solutions and intelligent systems which can handle complex operations better, while adding extra value and assured quality.
Automation brings reliability and efficiency, ultimately saving costs to produce the right quality every time. Swiss companies are specialized in many of these disciplines, with machinery for fabric inspection and presentation, labelling and tracking, folding and packaging. They have the technology to inspire a new vision at the post-production segment of the textile manufacturing processes. Optimization of workflows, with bottleneck management, is an obvious potential benefit. And it delivers measurable returns on investment. The wider picture with automation will prepare companies for the IoT and Industry 4.0.

New business models
The advantages of automation in mills with high-volume production are obvious: consistent quality, increased efficiency, waste reduction in some cases, as well as significant medium-term cost reductions in every case.
That description focuses on the aims of modern mills in low-cost markets. But producers in Europe and USA could reach out for more. For them, automation could be a game-changer, offering unique new opportunities.
Reshoring is a growing trend now. It shows great potential and is definitely driven by sustainability and changes in consumer mindsets. “We believe that the time is right – the machines and solutions certainly are – to push automation also to the very end of the production line, replacing intensive manual work and take the chance for reshoring. The current situation is kind of a transition time which is expected to last for a couple more years in the textile industry,” says Rueedi. He adds that any investments in these prime markets pay off much faster because of higher labour costs.
Innovation transformed through automation can do much more than simply replacing the nimble fingers of humans. It also enables new business models, guaranteeing prosperous future business, alongside greater job security.

Digital workflow and process control
The Swiss company Maag Brothers is a leading supplier of high-end machines for quality assurance in the final make-up processes, specifically fabric inspection, plating/folding, selvedge printing and packaging. Maag reports on a practical example from a mill in India which recognized the potential of automation.
An analysis at the customer’s mill identified the main goals as modernization of the workflow at quality control and packing processes. Maag’s new system covers tasks from fabric inspection to dispatch, and offers transparent and easily adjustable processes with real-time process control. It’s a digital solution, resulting in a slim organization, paperless, and the basis for further optimization towards Industry 4.0 to exploit its full potential. The customer’s own calculation showed a ROI for the installation at less than three years – along with a reduction in manpower and savings in fabric costs for shade samples.

Perfectly labelled, efficient data...
Smooth processes start with a label. Swiss company Norsel is an expert in grey fabric labelling systems, for piece tracking through all textile processes. High-quality label printing and proper sealing on all kind of fabrics ensure readability and sustainability after dyehouse processes such as mercerizing, high temperature dyeing and even hot calendering. No roll mix-up during dyeing, easy sorting of fabric rolls and rapid delivery make processes in the mill much more efficient. Using RFID codes lifts fabric inventory control to the highest level, with all information readily transferred to a database and integrated through any ERP software.
It’s a foolproof way to avoid the risk of human errors from hand-written notes on grey fabrics and article sheets, by opting for reliable, secure and forward-looking solutions.

Sample collections – the silent salesmen
First impressions count, so fabric producers like to present their collection perfectly – and that’s only possible with automated solutions. Swiss producer Polytex continuously refines its solutions, underlining its leading position in sample making equipment. Fully-automatic high-performance sample production lines are designed to satisfy the highest expectations. Fully-automatic lines or robotic machines set the standards for quality and performance. Even the most demanding clients can achieve their goals with impeccable samples, quickly and efficiently made, for flawless collections that are sure to impress.

Automation drives buying
First impressions are also the trigger for quick purchase decisions. The proof is there on every store shelf. Customers of Espritech are also well aware of it. They trust this Swiss producer of automated folding machinery to provide the final touch of class to home textiles and apparel products before they go on display. The folding systems are generally large mechatronic devices, loaded with latest technologies in mechanics, electronics, sensors and pneumatics. “Textile producers are amazed how folding machines solve the tricky task of reliably handling chaotically behaving materials. They see process optimization potential and the impact. We observe a slow but continuous change of mindset installing sophisticated technology even in the last steps of textile finishing,” says Philipp Rueedi, CFO at Espritech.

International technology group ANDRITZ will present its innovative nonwovens and textile technologies at the booth of its Indian representative PRN Techtex at Techtextil India 2021 in Mumbai, India, from November 25 to 27, 2021. A special focus will lie on its technologies for air-through bonding, needlepunch, textile recycling, and processes for biodegradable wipes, like spunlace and WetlaceTM.

Air-through Bonding
Air-through-bonding lines are the preferred choice for producing nonwovens with the best quality of softness and bulk for acquisition distribution layers, top sheets, and back-sheet products. With ANDRITZ carding machines and the new flat belt oven, customers benefit from high-performance fabrics from 16 to 80 gsm, produced with bicomponent fibers. Several Chinese customers have already invested in ANDRITZ aXcess carding machines, which provide perfect web uniformity. In addition, the CETI (European Center for Innovative Textiles) in Lille, France, has installed an air-through-bonding oven from ANDRITZ.

Textil-recycling Technologies
Recently, ANDRITZ acquired Laroche SAS, a leading supplier of fiber processing technologies such as opening, blending, dosing, airlay web forming, textile waste recycling, and decortication of bast fibers. The product portfolio further complements and increases the ANDRITZ Nonwoven product range. 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.

Needlepunch Technologies
Driven by the dynamic market for durable nonwovens, ANDRITZ has developed an elliptical pre-cylinder tacker – the PA3000. With this modern machine, ANDRITZ is responding to customer demands for higher capacities and lighter products. The PA3000 is an optimized cylinder pre-needleloom, which offers greater speeds and widths and has been specially developed for lighter webs. There is no friction between the web and the rolls, and there are no issues with the visual appearance.

ANDRITZ is also focusing on its latest needling technology for producing veloured felts, mainly for applications in the automotive industry.

In addition, ANDRITZ will be presenting the next generation of its batt-forming technology, the ProWin system. ProWin is a further development of ProDynTM and ProWidTM, which have achieved a high level of acceptance on the market with around 200 systems installed. This technology improves the current weight-profiling options and increases the actual production capacity.

Production of Bio-Wipes
For many years now, ANDRITZ has offered different nonwoven processes, such as spunlace and Wetlace, with one goal in mind: reduction and elimination of plastic raw materials while maintaining the high quality of the desired product properties. The latest development in this field is the ANDRITZ neXline wetlace CP line. This is a fully engineered production line, combining the benefits of wetlaid and drylaid technologies to produce a new generation of biodegradable wipes. This process achieves high performance entirely with plastic-free raw materials. The added benefit of using a blend of fibers, like wood pulp, short-cut cellulosic fibers, viscose, cotton, hemp, bamboo, or linen, without chemical additives, results in a 100% sustainable fabric.

Picanol has introduced its latest generation of airjet and rapier weaving machines, which have been called the “Connect” generation. These new generation weaving machines focus on connectivity and an increased level of data availability. With this new generation, Picanol is launching several new functionalities such as a digitalized Gripper stroke setting, Gripper tape monitoring, Climate control, Shed angle measurement, and fully integrated Power monitoring.

“Following the successful launch of our digital platform PicConnect earlier this month, we have now released a new generation of weaving machines, which are known as the Connect generation. Our Connect generation weaving machines can provide the correct data and are loaded with new and never-before-seen functionalities. This is clear proof that for Picanol “Driven by Data” is not just a slogan but a commitment. Not only have these innovations allowed us to make big improvements when it comes to our four design principles – Smart Performance, Sustainability Inside, Intuitive Control, and, of course, Driven by Data – but when combined with our new digital platform they will allow you to amplify your own intuition.” comments Johan Verstraete, Vice President Weaving Machines.

From now on, the range of Picanol weaving machines will have the “Connect” suffix. For the airjet weaving machines, this means: OmniPlus-i Connect and TerryPlus-i Connect, while for the rapier weaving machines, this means: OptiMax-i Connect and TerryMax-i Connect. These new machines are built around Picanol’s four main design principles:

Smart Performance
On the OptiMax-i Connect, Picanol has introduced a lubrication monitoring sensor in combination with a temperature sensor. The combined data they provide allow the user to make sure the gripper tapes are in optimal condition for maximum performance. As an option, a gripper stroke measurement sensor is also available. This not only dramatically simplifies the setting of the gripper stroke, but also enables the user to realize higher machine speeds when weaving reduced widths – a pure extra output combined with more user-friendliness.

Sustainability Inside
Even though it was 25 years ago that the Sumo Drive concept was launched, it remains the most powerful, versatile and energy friendly machine drive available. And it has been even further optimized. It features an optimized sheet metal package for lower energy consumption, optimized oil cooling circuit for a better performance and a built-in temperature monitoring. Moreover, the Connect machines can be equipped with a Power monitoring module, which allows the user to keep track of the power consumption of each machine over time. Every Connect machine also has a built-in ambient temperature and humidity sensor, which will help to optimize the climate control in the weaving shed at the lowest cost. And as raw material is the biggest cost factor, each machine can also be equipped with raw material use monitoring.

Driven by Data
As the machine has more sensors than ever before, it also generates more data. To enable a fast reaction to all these sensor data, the BlueBox control unit has been further optimized: better heat management guarantees short reaction cycles combined with the long lifetime of components. To have a good view of all of the data generated, a special sensor dashboard screen is available in the BlueTouch display: with a simple touch of the screen, the current and historical power consumption, temperature, humidity, material consumption, and – on the OmniPlus-i Connect – also the air consumption, can be monitored. The BlueTouch display is now also equipped with an Action center, an electronic logbook where all actions such as maintenance interventions can be logged or scheduled beforehand. The machine manual is now available on the BlueTouch display, and with the context-based help function the help pages related to the operation the user wants to perform appear with one touch of his/her fingertip. The built-in web browser even allows the user even to consult, for example, tutorial videos on the web to guide them through a setting procedure.

Intuitive Control
The Connect generation was designed to focus on what really matters: weave the highest possible grade A fabrics at minimal costs. A large set of tools have been installed to facilitate this goal. One of the most remarkable ones is the Harness frame stroke measurement – until recently, it was only available on the revolutionary SmartShed, but it is now also available on the cambox and dobby machines. Combined with the shed visualization and simulation, it offers a quantum leap in terms of optimizing the user’s shed settings without losing any time or taking any risks. The colors of the programmable Smart signal lights with stop timing functionality are now repeated around the push buttons, allowing even better visibility and the prioritization of interventions by the weaver. A full-fledged Access control system not only limits the access to certain pages and settings depending on the user, but also allows a tailored dashboard to be established for each user profile.

• At this year’s INDEX from October 19th to October 22nd, Truetzschler Nonwovens, Truetzschler Card Clothing and Voith introduce new solutions for manufacturing a broad range of sustainable nonwovens for wipes, hygiene or medical textiles at booth 2327.

Plastic-free initiatives worldwide affect everyone: consumers, product developers, nonwoven producers and finally nonwoven machinery suppliers.

Truetzschler Nonwovens and Voith address the quest for more sustainable and affordable nonwovens in the wipes segment by two proven technologies for manufacturing pulp-based nonwovens. Firstly, WLS (Wet-Laid/Spunlaced) lines. More than a handful are in service worldwide and mainly target the flushable wipes market. At INDEX we’ll introduce our latest nextLevel/WLS baby and body wipes, a joint development by Voith and Truetzschler.

The second focus is on carded/pulp (CP) products. A CP line – including a TWF-NCT card placed between the HydroFormer and the AquaJet is already running to full capacity at customer site. Various CP materials, including innovative nextLevel/CP wipes, will be on display at the booth and invite visitors to discuss characteristics, benefits, line concepts and equipment.

When talking sustainable nonwovens, solutions for efficiently manufacturing biodegradable nonwovens from virgin cotton fibers, comber noils and viscose/lyocell fibers must not be missing. Visitors can look forward to directly comparing cotton nonwovens to a broad range of cellulose-based material.

Truetzschler Card Clothing, our in-house competence center with respect to card clothings and comprehensive service, presents its latest development, the Z wire for high-speed roller cards. A new geometry minimizes fiber fly and allows for better carding and more stable web forming.

„Your reliable partner in the nonwoven industry“ – the slogan speaks for itself: Oerlikon Nonwoven is exhibiting at the world’s leading nonwovens trade fair – the INDEX in Geneva, Switzerland (October 19-22, 2021) – with one of the market’s broadest portfolios. The Neumünster-based systems constructor will be focusing on market- and customer-oriented system solutions for filtration, hygiene, medical, geotextile and other industrial applications. Trade fair visitors can delve deep into the company’s comprehensive product and process know-how both live at trade fair stand no. 2314 and via the INDEX online platform.

• Nonwovens for filtration, insulation and sorption applications
• Comprehensive spunbond portfolio
• Quality Sized Right-Technology: spunmelt systems for the hygiene and medical market
• Wipes using Oerlikon's Phantom technology
• Airlaid technology for sustainable nonwovens

• 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.

Originally conceived as a low-cost, high-volume alternative to knitting and weaving, nonwovens was already expanding its market boundaries by the 1970s with new applications in ‘disposables’ such as diapers, hygiene and teabags.

In the past five decades, the nonwovens business has exploded in all directions, reaching a global market worth USD 40.5 billion in 2020, projected to grow to USD 53.5 billion by 2025. This annual growth rate of 5.7% (MarketsandMarkets, Nonwoven Fabric Market Report) is based on countless new applications and expansion into durable, as well as additional disposable, products.

Major growth drivers include the hygiene sector, and filtration media for power plants and air conditioning systems. Especially during the peak of the COVID pandemic in 2020 and 2021, demand in the hygiene sector multiplied. Worldwide capacities for both meltblown and spunlace production rocketed compared to a normal business year. Swiss Autefa Solutions, for example, significantly benefited from this trend, notably with the launch of a fully-automatic machine for producing face masks.

The automotive industry is the second big growth area, with many new applications being pioneered. The trend to electric and hybrid vehicles has helped this, as nonwovens reinforced with carbon fibres are widely used as battery housings.

Swiss nonwovens competence
Innovative applications across all sectors have driven the rapid evolution of sophisticated nonwovens machinery. Today’s trends demand higher productivity, sustainability and Industry 4.0 compatibility – demonstrated by the full equipment portfolio of Swiss Textile Machinery member Autefa Solutions. With V-Jet Futura, the company recently sealed the link in its product range between web forming and drying technology. This latest Hydroentanglement Machine, together with the SQ-V Square Drum Dryer, embodies advanced technology combined with significant reductions in energy consumption compared to other process solutions.

A vital contribution to nonwovens production is offered by Rieter subsidiary Graf, a leading supplier of clothing and combs for carding and combing processes in spinning and nonwovens. Graf's Hipro card clothings – suitable for any man-made fibres in the nonwovens sector – are focussing on higher productivity. Their superior performance delivers up to 10% higher throughput and greater carding efficiency compared to conventional clothings. These reliable card clothing elements also ensure a consistently reproducible high web quality, as well as 20% fewer failures in the web, thanks to the precise fibre transfer to and from the cylinder.

Another constant trend in nonwovens today is the drive for better quality. Manufacturers want to take charge of contamination levels in their processes, as well as eradicating defects which may arise during production. Uster Technologies, a leading provider of quality management solutions from fibre to fabric, offers a combined solution to achieve both these required quality standards. At the fibre preparation stage, Uster Jossi Vision Shield N ensures the best possible initial inspection and removal of contamination. Then, at the end of the production sequence, Uster EVS Fabriq Vision N handles automated detection and marking of all the main defects caused during production. This combined solution avoids material waste and takes full advantage of the potential for process optimization.
