From the Sector

The Karl Mayer Group is reducing its ecological footprint when it comes to energy utilisation: The Group's largest photovoltaic system to date has just been installed at its headquarters in Obertshausen.

Following the construction of a stable substructure, the first photovoltaic elements were installed on the roof of the assembly hall in Obertshausen on 16 February 2024. This will be followed by the step-by-step conversion of other roofs. If everything goes according to plan, around 6,000 modules will have been installed on an area of approx. 12,000 m² and over 60,000 metres of cable laid by the middle of the year.

"With a total output of 2.4 MWp, we will be able to generate over 35% of the total electricity consumption at the site ourselves," explains Michael Sustelo, Head of Facility Management at the Karl Mayer Group.

• Business situation remains poor and unchanged
• Manufacturers show prudence in forecasting future developments

 
According to ITMF’s Global Textile Industry Survey (GTIS) conducted in the middle of September 2023, survey participants exhibited a cautious sentiment regarding the current business situation. The indicator for the business situation stood at -27 percentage points (pp, see Graph 1) because companies in the entire textile value chain were struggling with rising costs and weak demand. Business expectations have remained unchanged since July at around +20 pp (see Graph 2). They have jumped into positive territory in January 2023 based on the assumption that the Chinese economy would give an additional boost, but this hope did not materialise. The analysis indicates that a hard landing of the global economy is not in sight.

Order intake recovered in May 2023, but flattened in July and remained very weak in September (-28 pp). The entire textile value chain is running on minimum levels of orders. As long as brands and retailers do not increase orders, the entire value chain will continue struggling. Order backlog slightly increased globally, from 1.9 months in July to 2.2 months in September 2023. This indicator had been on a falling trend since the end of 2021. The average capacity utilisation rate dropped again globally (69%). Textile manufacturers expect this rate to remain low in six months’ time as well.

Weakening demand has been the major concern in the global textile value chain for a year. In September 2023, this concern grew even stronger due to high inflation rates measured in the last few months, a phenomenon fueled by high energy and high raw material prices. Nevertheless, participants seem not to be concerned by order cancelations and inventory levels remain average along the textile value chain. 

Members of TMAS – the Swedish Textile Machinery Association – will be taking part in the forthcoming ITMA Asia + CITME exhibition, taking place from November 19-23 2023 at the National Exhibition and Convention Centre in Shanghai, China.

Weaving
In the area of weaving, 93% of the 114,000 new looms delivered in 2022 went to Asia, according to the latest figures from the International Textile Manufacturers Federation (ITMF), with China the top destination, followed by India.
As a result, TMAS members like Vandewiele Sweden AB and Eltex have a huge market to address that has been established over many decades.

Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of the market-leading Vandewiele Group, supplying weft yarn feeding and tension control units for weaving looms to the majority of weaving machine manufacturers. It also retrofits its latest technologies to working mills to enable instant benefits in terms of productivity and control.

Yarn and sewing thread monitoring
With nearly 70 years of expertise in yarn sensor technology, Eltex of Sweden AB has been at the forefront of new product development. Its EYE and EyETM systems are capable of accurately and efficiently monitoring the movement and tension of more than 1,000 yarns simultaneously. These systems are suitable for various applications and fibre types, including warping, winding, multiaxial weaving and new material applications.

Eltex sewing tension monitors, such as the ETM422, have been well-received by customers. This device can monitor the tension of sewing threads in real time, effectively improving the quality and safety of sewn products. Particularly in China's rapidly growing automotive manufacturing sector, the ETM422 has seen widespread use to meet the industry’s escalating demands for product safety and quality.

Dyeing and finishing
“Digitalisation, automation and AI have become the key enablers for sustainable gains across the entire textile industry and so much has been achieved in the past few years, especially in terms of automation,” says TMAS secretary general Therese Premler-Andersson. “One area in which TMAS members are really making a difference right now, is in replacing water and energy-intensive technologies for the dyeing and finishing processes with new digital technologies.”

The TexCoat G4 non-contact spray technology for textile finishing and remoistening, for example, will be showcased in Shanghai by Baldwin. It not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to a customer’s requirements in terms of single and double-sided finishing applications. The TexCoat G4 can reduce water consumption by as much as 50% compared to traditional padding application processes.

West Yorkshire is to have a first-of-its-kind apprenticeship training course for textile engineering technicians, reflecting a resurgence in the industry locally, and more generally in the UK.

Calderdale College has partnered with the Textile Centre of Excellence (TCoE) and the British Textile Machinery Association (BTMA) to develop the bespoke Level 3 apprenticeship course which will start in September 2023.

Engineering Technician apprentices at Calderdale College will receive training from the TCoE, helping them to develop the engineering maintenance skills required to close the skills gap in West Yorkshire’s textile industry.

While the region has been a flourishing hub for textile excellence since the 19th century and is being revitalised through digitalization and the localisation of supply chains, its success is currently being hindered by an ageing workforce and high staff turnover.

Through adapting the engineering training at Calderdale College to address the current requirements of the textile industry, the unique new course will ensure the passing on of vital know-how and good practice aligned with the new skills demanded by Industry 4.0 and automation.

Collaborative Apprenticeships
Calderdale College has developed the programme over a two-year period through close collaboration with the TCoE and the BTMA, as well as through consultation with British heritage weaver AW Hainsworth and a number of other local textile companies.

The course launch follows on closely from the success of the Collaborative Apprenticeships project launched in 2022 at Calderdale College. To date, this has seen the college engage with over 100 local employers on the benefits of increasing the quantity and improving the quality of the apprenticeships that they offer, as well as encouraging others to introduce apprenticeships for the first time.

“Over the years, we’ve seen how beneficial apprenticeships can be for several sectors, particularly in terms of helping businesses to retain staff and ensuring that they have a steady flow of skilled workers coming in,” said Claire Williams, head of employer engagement at Calderdale College. “Having identified that employers in the textile manufacturing industry were struggling to find apprenticeship training that was designed around their needs, we knew that alongside employers and our partners, we needed to satisfy this critical gap in the market. We hope that this programme will act as a leading example for the rest of the industry to follow.”

ITMA 2023 was a successful platform for the flat knitting machine manufacturer STOLL to present its latest new developments. The business unit of the KARL MAYER GROUP will be following up this fair on 3 July with the launch of a further innovation package. With the solutions contained in this package, STOLL will be offering its customers additional added value when using their flat knitting machines - in line with the concept of bundling innovations.

The new features include an optimised central lubrication system that reduces both maintenance effort and oil consumption, this as standard from July 2023 for all models of the CMS and ADF series produced in Reutlingen.
Compared to the previous optional variant, it ensures more efficient and comprehensive lubrication. All needle bed elements, from the holding-down jack to the coupling part and intermediate slider to the selection jack, are now supplied with oil. The machine itself recognises whether lubrication is required. Independently of this, the lubrication intensity and oil distribution can be adapted to the individual machine conditions by setting various parameters, if required. To ensure that the required amount of lubricant is reliably supplied, a message is sent if the level is too low.

In addition, a new oil drain container as standard equipment for all CMS and ADF models catches used oil from the needle bed under the machine. This prevents soiling of floors or knitted fabrics. The emptying of the container can be efficiently managed by an adjustable reminder function. The neat and at the same time sustainable solution does not require cleaning agents or hoovers and offers the possibility to reuse the oil after cleaning through special filters, if necessary.

Users of CMS and ADF belt take-down machines can benefit from optimisations around the belt take-down. Thanks to the new STOLL innovation package, this can be turned forwards and backwards by means of a switch as standard in order to easily eliminate fabric wraps and thus reduce maintenance times. In addition, a mirror, which is also fitted as standard, ensures a simple visual check of the belt take-down.

Another solution of the STOLL innovation package from July 2023 includes new cams that enable split-stitch implementation without cam box modification. This reduces manual effort and thus conversion times and costs. The feature is standard on all fine gauges ADF and CMS machines.

For the W machines from STOLL, there is now a further inlay yarn carrier, the Qt, in addition to the previous Qw yarn carrier. The extension means that the number of inlay yarn carriers used in a system can be increased from the previous one to three. No additional system is required for the weft yarn, and the process steps weft yarn insertion and knitting take place in the same system.

At ITMA 2023, EFI™ Reggiani is presenting its sustainable Reggiani ecoTERRA pigment printing line up, the high-speed EFI Reggiani HYPER and Reggiani BOLT XS direct-to-fabric printing solutions, and EFI Inèdit end-to-end digital textile workflows.

The EFI Reggiani ecoTERRA solution is an all-in-one solution for water-based pigment printing that requires no ancillary equipment for pre- and post-treatment. By reducing water, energy and chemicals consumption in the overall process, customers can now obtain a sustainable, direct-to-fabric printing solution. For the first time at ITMA, EFI Reggiani is presenting its full ecoTERRA line up of four models, including a 340 printing width, with speeds ranging from 150 to 600 sqm/hour. This allows customers to choose the best TCO/ROI based on output volume and speed range.
 
Reggiani ecoTERRA water-based pigment inks deliver excellent wet and dry fastness properties, sharpness in detail, and durability while also ensuring printhead longevity with reduced maintenance costs. Thanks to the enhanced polymerisation and finishing unit, EFI Reggiani ecoTERRA also provides an enhanced tactile experience and fabric softness.
 
In addition to highlighting EFI Reggiani’s sustainable product offering, the company will also demonstrate the significant productivity and efficiency advantages offered by its portfolio of high-speed, high-performance digital textile printers at ITMA 2023. Attendees will discover how mass production can transition to a digital, on-demand workflow with the high speeds and high print quality of the EFI Reggiani HYPER scanning printer and the next-generation EFI Reggiani BOLT XS single-pass textile printer.

Visitors to the booth also will see EFI Reggiani’s new proprietary end-to-end digital printing workflow and the latest enhancements to EFI Inèdit digital textile software. Inèdit, now part of EFI Reggiani, is one of the leading developers of raster image processors (RIPs) and related software for digital industrial textile printing. The EFI Reggiani end-to-end workflow with Inèdit integration boosts productivity and production capabilities for digital textile print operations while ensuring maximum security for customer’s designs thanks to two-level encryption.
 
EFI Reggiani QUERY, the user-friendly, advanced data analysis tool to measure printer performance, keep track of real costs per metre, and monitor water and energy consumption, will also be demonstrated.

From April 25^th to 27^th, 2023, the Institute of Textile Machinery and High Performance Material Technology (ITM) of TU Dresden will be exhibiting at the pavilion SAXONY! at JEC World 2023.

The ITM will provide a comprehensive overview of its current research in the field of machine and product development along the entire textile process chain.

The upcoming JEC 2023 exhibition will highlight innovative Customised Connective Cores (CCC), which are custom-made core-insert structures additively manufactured using cellular metal and a form-fit integrated insert. These CCCs can be seamless integrated either as patches or as full-surface core material into lightweight panels, offering significantly improved load-bearing behavior (especially 4 times the load-bearing capacity and fail-safe behavior) compared to existing technologies. This breakthrough opens up new possibilities for fastening lightweight panels.

Another highlight at the exhibition is the repair process for fibre-reinforced composites (FRP) developed at the ITM. Instead of mechanically grinding the damaged area, the matrix in the repair area is locally dissolved using a UV-rays-induced depolymerisation process. Damaged fibres can thus be replaced by a customized repair patch. Free yarn ends on the textile repair patches are spliced with the UV-exposed yarn ends in the repair area using an adapted splicing process. In this way, a very clean, simplified and mechanically improved repair area can be achieved compared to the state of the art.

The diverse possibilities offered by the structure and process simulation of textile high-performance materials and textile manufacturing processes will also be presented. By means of multi-scale modelling and simulation, a profound understanding of materials and processes is achieved at the ITM. Finite element models on the micro, meso and macro scale have been developed and validated for this purpose. Examples from current ITM research projects demonstrate the various possibilities and areas of application of modern simulation methods in the field of textile technology.

Moreover, an innovative process for the integral manufacturing of 3D rib-stiffened preforms with complexly arranged stiffeners in 0°, 90° and ± 45° orientation was developed and successfully implemented at the ITM. Due to the process-integrated structure fixation and the continuous fibre reinforcement between shell and rib structure, the 3D preforms are perfectly suited for the production of highly load-bearing FRP components with increased bending stiffness, which will be exhibited at JEC. Hence, the lightweight construction potential of high-performance fibres can be fully exploited.

A successfully established development are partially flowable 2D textile reinforcement fabrics that are continuously manufactured in one single process step. For this purpose, the entire process chain was developed at the ITM, which allows a cost-effective and high-volume production of load-bearing thermoplastic 3D FRP components with continuous fibre reinforcement between shell and stiffeners.

At JEC 2023, the ITM will also present a partially embedded textile latice girder as reinforcement for carbon concrete applications, which was produced by means of an innovative textile manufacturing process based on the multiaxial warp knitting technology. Through the development of a customized warp insertion, manipulation and take-off system as well as appropriate shaping methods, it is now possible to produce tailored textile semi-finished products, e.g. for use in wall and ceiling panels. These textile latice girders represent a resource-saving alternative to conventional steel girders due to the reduced among of concrete required and the additional cavity for media and cable guidance.

The integration of textile actuators and sensors in FRP provides structures with additional functionalities. The research and application of such interactive FRP with different matrix materials (e.g. with thermoset, elastomer or concrete matrix systems) for structural health monitoring or adaptive systems is one of the key research areas of the ITM.

Moreover, the development and implementation of innovative yarn constructions based on recycled high-performance fibres (e.g. rCF, rGF, rAR) for sustainable FRPs is successfully promoted at ITM. By use of a special carding machine, recycled fibres are opened up, separated and joined to form a wide, uniform ribbon. Subsequently, innovative hybrid yarn constructions made of evenly mixed recycled high-performance and thermoplastic fibres with variable fibre volume fractions can be manufactured by means of various spinning technologies. Selected yarn constructions and components will be showcased at JEC.

Textile companies could take full advantage of expanded print opportunities with EFI™ Reggiani textile solutions presented at the 8-13 December India ITME Exhibition in Greater Noida.

The EFI Reggiani TERRA Silver printer was shown at ITME 2022: a solution to enter the industrial printing segment with a short, smart and green process. The EFI Reggiani TERRA Solution eliminates the need for steaming or washing on direct-to-textile applications, using a greener, more efficient polymerisation process that takes place as the printed textile goes through the printer’s on-board dryer. As a result, users can achieve superior printing results while using less time, water, and energy.

The EFI Reggiani exhibit at ITME was also promoting:

•  EFI Reggiani HYPER printer, a scanning printer available in 1.8-metre, 2.4-metre or 3.4-metre widths that prints at up to 20 linear metres per minute peak speed, making it the fastest textile scanning printer on the market;
• Mezzera Concord, the continuous rope washing line from the specialist in washing solutions that transports fabric by overflow for tensionless running with an independent squeezing mangle for each channel;
• One of the industry’s broadest line-ups of high-end, superior-quality textile inks, including EFI Reggiani AQUA and EFI Reggiani Diamond reactive, IRIS dye-sublimation, ARIA direct disperse, FUOCO acid, and GEA and TERRA pigment inks; and
• Inèdit, recently acquired by EFI Reggiani, a developer of raster image processors (RIPs) and related software for digital industrial textile printing with their product portfolio that features proven, highly advanced workflow solutions for textile profiling, calibration, design integration and much more.

• Formula 1 cars will be cheaper in future

Carbon is the stuff Formula 1 cars are made of, at least the bodywork. But until now, carbon has been expensive. It can be produced more cheaply and efficiently if artificial intelligence monitors the production processes. A camera system combined with artificial intelligence automatically detects defects in the production of carbon fibres. This makes expensive manual inspection of the carbon fibres obsolete and the production price of the carbon fibre can be reduced in the long term.

For this idea, the young engineer Deniz Sinan Yesilyurt received the second prize of the "Digitalisation in Mechanical Engineering" Young Talent Award on 6 December.

Carbon fibres are sought after because of their good properties. They are very light - they weigh up to 50 percent less than aluminium. The combination of low weight and good mechanical properties offers many advantages. Especially in times of the energy transition, lightweight materials like carbon are more relevant than ever before. At the same time, carbon fibres are as resistant to external stresses as metals. However, achieving these good properties of carbon fibres is very complex.

Up to 300 individual fibre strands - bundles of individual fibres - have to be monitored simultaneously during production. If carbon fibres tear, it costs time and money to sort out the damaged fibres. This is just one example of various defects that can occur in the fibres during production.

Therefore, Deniz Sinan Yesilyurt attached a camera to the carbon fibre line that takes pictures of various fibre defects during production and collects them in a database. The artificial intelligence in the camera's information technology system evaluates the fibre defects by assigning the images to predefined reference defects. In doing so, it recognises various fibre defects with a classification accuracy of 99 per cent. The process can also be used in other areas that produce chemical fibres.

Deniz Sinan Yesilyurt received the prize from the German Engineering Federation (VDMA) in Frankfurt am Main, Germany. He is a Bachelor's graduate at the Institut für Textiltechnik (ITA) of RWTH Aachen University. The full title of his bachelor's thesis is: "Development of a Kl-supported process monitoring using machine learning to detect fibre damage in the stabilisation process". The VDMA awarded the prize to a total of four theses from different universities. The prize is awarded for outstanding theses and was offered in Germany, Austria and Switzerland.

Monforts will be presenting its finishing technologies at the forthcoming Igatex textile machinery exhibition, which takes place from December 1-4 at the Lahore Expo Centre in Pakistan.

The importance of the textile industry to Pakistan’s economy cannot be overstated – it accounts for 60% of the country’s overall exports and some of its industry’s players are very major employers. In the year to June 2022, Pakistan’s textile exports climbed by 25% to a record value of $19.3 billion according to the country’s Bureau of Statistics, as security of deliveries – especially to Europe and the USA – worked in the country’s favour, in the light of the Covid-19 pandemic and subsequent supply chain issues. It has a key role to play in quickly getting the country back on its feet after the devastation.

Monforts customers in the regions around the country’s three biggest cities of Karachi, Lahore and Faisalbad include all of the main players in the fields of home textiles and denim production, including Afroze, , Al Karam Artistic Milliners, Azgard-9, Crestex, , Gul Ahmed, Interloop, Liberty Mills, Lucky Textile Mills, Mustaqim, Naveena (NDL), Rajby Industries, Sapphire Finishing, Soorty, Style Textile and US Denim.

These companies rely on established Monforts technologies including Montex stentering equipment, Monfortex sanforizing units and Thermex dyeing ranges. The company’s Matex Eco Applicator minimum application system has also proved a big hit in recent years.

Monforts has also achieved considerable success in Pakistan with its Econtrol®* dyeing system  – an effective and established dyeing process. More than 40 Thermex continuous dyeing ranges have been installed in Pakistan in recent years and operator training on the Econtrol®* process by sophisticated technologists is an additional service.

The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step. Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

An immediate wash off is also unnecessary, allowing for flexible production planning. The process is suitable for pale to dark shades with very good fastness properties. Also waste water treatment is improved by this technology.
