From the Sector

Giorgio Calculli has been appointed new managing director of ACIMIT, the Association of Italian Textile Machinery Manufacturers. A law graduate with a Master’s degree in training and employment policies, he has been on staff at ACIMIT since 2006 as head of the Association’s training, internal relations and technical department. Calculli takes over as ACIMIT managing director from Federico Pellegata, who after 25 years managing the Association has been appointed CEO of ACIMIT Servizi srl, the company set up by ACIMIT to provide services in support of associated member companies for the promotion of the Italian textile machinery industry in Italy and abroad.

“It has been a truly enriching experience,” asserts Federico Pellegata, “for which I am grateful to our associated members, ACIMIT’s Board, and the Association’s presidents who have served during my years in ACIMIT. However, my commitment to continue to promote the Italian textile machinery sector by no means ends here. As CEO of ACIMIT Servizi, I will continue to work relentlessly to ensure that ITMA, the world’s primary textile machinery trade fair, remains a representative showcase for the success of Italian manufacturers in the sector, as has been the case for the editions of the exhibition held in Italy in 2015 and 2023.”

ACIMIT managing director Giorgio Calculli comments: “I wish to thank the Board of ACIMIT for the appointment and for the opportunity to lend continuity to the work carried out by Federico Pellegata, for whom the success enjoyed at the latest edition of ITMA is only the most evident expression. I will work to further develop the membership base and ensure member companies receive maximum support from the Association in their business activities.”

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.”

As of the beginning of 2023, Zünd Systemtechnik AG acquired its long-standing sales partner Sign-Tronic S.A, which is based in Barcelona.

Sign-Tronic S.A. has been a wholly owned subsidiary of Zünd Systemtechnik AG since the start of 2023 and now operates under the name Zund Ibérica. Sign-Tronic S.A. was established in 1990 and has been an official sales and service partner of Zünd Systemtechnik AG since 1994. Zund Ibérica serves numerous customers in Spain, Portugal and Andorra.

Jordi Lorente is the new CEO of Zund Ibérica. For the time being, he will be actively supported by the previous co-owner and Managing Director Flemming Jensen. Rosa Miralles, also a co-owner, will continue to work in an executive capacity at Zund Ibérica.

Zund Ibérica currently employs 15 people. With more than 1,000 cutters installed, Zund Ibérica is one of the most experienced distributors of both digital cutting systems and software and workflow solutions on the Iberian market. It has its own showroom, which allows customers and interested parties to experience the many possibilities of Zünd’s digital cutting technology in person. Its staff consists of proven experts in consulting, training, installation, and service.

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.

A new fabric inspection technique for accurately detecting the most subtle of defects on patterned fabrics during high speed production has been developed by BTMA member Shelton Vision, of Leicester, UK.

The patent-pending system has been integrated into the company’s WebSpector platform and validated through factory trials on a purpose-built full scale in-house demonstration system with sophisticated fabric transport capabilities. As a result, a first system has already been ordered by a manufacturer of both plain and patterned fabrics, including camouflage, in Colombia. This follows the successful conclusion of a 21-month Innovate UK project in which techniques for the resolution of complex pattern deformations were developed by machine vision and computer scientists in the company, backed up by the machine vision and robotics department at Loughborough University.

Restrictions
Traditional methods for defect detection rely on human inspection which is ineffective, with detection rates under 65%, while the Shelton WebSpector machine vision system offers a sophisticated platform for automated defect detection of over 97%, but until now has been restricted to plain textiles.

While pattern matching and neural network approaches have previously been tried for patterned textiles, they have failed to provide a practical solution due to the extreme complexity associated with pattern matching on deformable substrates like textiles, as well as the time required to train a neural network for each pattern type.

Challenges
The challenge is that fabrics are not rigid and can be creased or stretched and are also subject to local distortion,” says Shelton Vision Managing Director and CEO Mark Shelton. “As a result, inspection without the technique we have developed, would lead to thousands of false positives. Our sophisticated pattern inspection software techniques ensure a clean image, allowing the detection of faults on fabrics running at speeds of up to a hundred metres a minute.”

The full system consists of:

• A camera and lighting system for optimum image capture at high speed and associated image processing hardware.
• Self-training software utilising statistical analysis to automate the system configuration for new textile products.
• An advanced suite of defect detection algorithms for the detection of all textile defect types.
• An AI-driven defect classification system which learns and automates defect naming in real time, as well as a real time defect grading capability based on client decision rules.
• A system for recording and retrieving complete roll map images for subsequent review and quality control.

The generation of textile roll maps with complete defect data allows for an optimised textile cut plan, improved downstream processing and quality assurance.

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.”
