Aus der Branche

Members of TMAS – the Swedish textile machinery association – will display technologies in alignment with the theme of digitalisation at the forthcoming Techtextil and Texprocess 2024 exhibitions, taking place in Frankfurt from April 23-26th.

Automatic handling
The fully automated and digitised handling solutions for finished garments, home textiles and furniture of Eton Systems, for example, will be demonstrated at Texprocess.

Designed to increase value-added time in production by eliminating manual transportation and minimising handling, the individually addressable product carriers are fully managed and controlled by the latest ETONingenious™ software. This web based real-time data collection and information system continuously accumulates, processes and makes all production information instantly available to supervisors, quality control personnel and management.

Bespoke seams
Svegea will demonstrate its EC 300-XS colarette technology, which is used by garment manufacturers around the world for the production of tubular apparel components such as cuff and neck tapes and other seam reinforcements.

The EC 300-XS collarette cutter on show in Frankfurt is equipped with the latest E-Drive II system providing the operator with a very user-friendly touchscreen, providing full control of the cutting process. An accompanying FA 350 fully automatic roll slitting machine will also be demonstrated.

Digital finishing
At Techtextil meanwhile, Baldwin Technology Co. will provide full details of how its highly digitised TexCoat G4 non-contact spray technology for textile finishing and remoistening not only reduces water, chemicals and energy consumption, but also provides the flexibility to adapt to customer requirements in terms of single and double-sided finishing applications.

TexCoat G4 can reduce water consumption and chemical usage by as much as 50% compared to traditional padding application processes.

Yarn tension
Celebrating its 60th anniversary this year, Eltex will display the latest Eltex EyETM system for the continuous monitoring of yarn tension on warp beams.

The Eltex EyETM eliminates problems when warping, and also in subsequent weaving or tufting processes, monitoring the yarn tension on all positions in real-time and enabling a minimum and maximum allowable tension value it be set. If any yarn’s tension falls outside these values the operator can be warned or the machine stopped.

The Eltex ACT and ACT-R units meanwhile go beyond yarn tension monitoring to actually control yarn tension. This extends the application range greatly. The plug and play system automatically compensates for any differences in yarn tension that arise, for example from irregularities in yarn packages.

Accumulated know-how
Vandewiele Sweden AB benefits from all of the synergies and accumulated know-how of 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.

The company will present its latest X4 yarn feeders with integrated accessory displays (TED) as a new standard, as well as launching its own e-commerce platform – iroonline.com.

The TED function enables weft tension settings to be transferred from one machine to another, enabling a fast start-up the next time the same article is woven. The position of the S-Flex Tensioner is constantly monitored by an internal sensor – even if adjustment is made during power off.

X4 feeders are also available with integrated active tension control (ATC-W) as an option. With the ATC-W active tension control, the required tension is easily set and monitored on the integrated display. Once set, the system constantly regulates itself, ensuring consistent yarn tension during the weaving process which is constantly and accurately measured by the ATC sensor unit, sending a signal to the ATC operator unit resulting in consistently stable yarn tension at the required level.

Over the past year, TMAS, the Swedish Textile Machinery Association, has been working with ClimatePartner on a corporate carbon footprint (CCF) mapping project with its member companies, as a natural step towards supporting a more sustainable textile industry.

Over half of the members of TMAS are participating in the project, which involves calculating each operation’s Scope 1, 2 and 3 emissions in order to identify the current climate impact and areas where reductions can be made.

“Integrating climate action into strategies is becoming increasingly important in Europe and we have decided to take a pro-active role,” says TMAS secretary general Therese Premler-Andersson. “There is growing pressure from customers to be more transparant in this area and forthcoming legislation will soon make it necessary for all to take climate actions. TMAS members, however, recognise the benefit of taking action now, not least in terms of taking responsibility and demonstrating credibility.”

The CCF project’s scope examines all aspects of a business split into five areas:

• Facility Management (heating, electricity, water, cooling agents and waste disposal).
• Employee Mobility (commuting and company cars).
• Business Travel (flights travel by train, rental cars).
• Procurement (production, packaging and office materials).
• Logistics (inbound and outbound).

Primary data is being used wherever possible and emission factors originate from internationally recognised databases such as ecoinvent and GEMIS.

The ClimatePartner measurement programme is based on the guidelines of the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard (GHG Protocol), and factors in all greenhouse gases covered by the Kyoto Protocol. These are carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulphur hexafluoride (SF₆) and nitrogen trifluoride (NF₃).

Each of these gases affect the atmosphere differently and remain in the atmosphere for different lengths of time. Rather than reporting on each gas separately, they are expressed as a CO₂ equivalent (CO₂e) for the sake of simplicity. A CO₂e is essentially a conversion into a ‘global warming potential’ value that enables the influence of different gases on global warming to be compared.

TEXO AB, a member of TMAS, the Swedish textile machinery association, is currently seeing a surge in demand for its Compfelt weaving looms for press felt base fabrics.

“These are far from standard machines,” explains TEXO President Anders Svensson. “Off-the-shelf industrial weaving machines generally range in their working widths from 1.9 to 3.2 metres, with those purpose-built for technical applications such as geotextiles extending to wider widths of six metres and beyond. Meanwhile, one of the machines we have recently successfully delivered and commissioned has a working width of 23 metres and is not even the widest of the many such machines the company has engineered and delivered worldwide since its formation.”

A second recently-delivered line has a more modest working width – in relative terms – of 13 metres.

Paper machines
The demand for such machines comes from the suppliers of paper machine clothing (PMC) to paper mills, who in turn operate colossal machines for paper manufacturing.
On of the largest paper making machines is currently believed to be located on Hainan Island off the southern coast of China and is 428 metres long – roughly the length of four football pitches. Naturally, such machines require equally large-scale components, which is where TEXO comes in. All paper machines require a regular supply of PMC fabrics which are employed in three separate areas of the paper machine – the forming section, the press section and the drying section.

Press felts
TEXO Compfelt weaving machines are specifically employed for the production of endless (tubular) woven base fabrics for the press section of paper machines, where water is mechanically removed from the newly formed sheet of fibres. In the simplest press, the sheet is carried by the PMC fabric between two rolls, where water is squeezed out by the application of load and pressure. This can also be assisted by the use of vacuum and heat. The PMC fabrics here need to be replaced regularly, with a maximum lifespan of six months.

Press felts have become increasingly sophisticated over the years, consisting of complex woven base structures which are subsequently combined with nonwovens via needlepunching on equally huge machines. The woven base fabrics are primarily made from polyamide for its strength and hygroscopic and elastic properties.

Dobby harness
“A major refinement of the machine has been the ability to equip it with up to 24 dobby harness frames to meet the demand for sophisticated structures from the PMC manufacturers. Although the PMC business represents a small proportion of the total cost of manufacturing paper, it can have a significant impact on the quality of the paper, the efficiency of a machine and machine production rates.”

Another significant development has been that of a self supporting base pre-filled with concrete, which has eliminated the need to dig out foundations in a plant to support the machine.

Retrofits
TEXO’s looms are built to last, but technology moves forward, and the company is also currently active in the retrofitting of existing machines built as far back as the 1970s.

Integration
TEXO has also just integrated its offices and production centre at its base in Älmhult, Sweden, to create a unified 5,000 square metre site.

Fully integrated production lines from single source suppliers have increasingly become the norm in the textile industry and make complete sense in meeting today’s complex supply chain needs, according to TMAS – the Swedish Textile Machinery Association.

“Over the past few decades, textile mills have transitioned from consisting of collections of individual machines serviced and maintained largely by in-house mechanics as well as separate supplier companies for each part of the production line,” says TMAS Secretary General Therese Premler-Andersson. “Those in-house engineering service teams have diminished over the years, while the introduction of electronic drive systems in the 1980s and 90s also put an increased emphasis on the need for third party electrical engineers, operating separately to the machine builders.

“Subsequently, mechanical machines and electronic drive systems became much more integrated, and more recently, with the advent of digitalisation, entire production lines are becoming centrally controlled with remote, instantaneous connections to their suppliers for service and maintenance.

“In this context, the integration of machinery and automation specialists as single-source suppliers makes perfect sense, while partnerships between machine builders and their customers have never been more important.”

The recent acquisition of Nowo textile machinery from its previous owner, Brandstones Ab Oy, by TMAS member ACG Kinna, she adds, is a good example of this general trend.

Nowo, headquartered in Turku, Finland, designs, manufactures and exports high-end textile production machinery mainly for the fibre processing industry. At the end of the 1980s it introduced the highly successful Nowo Vac pillow filling system, which has been its best-selling system, alongside the Noworoll ball fibre machine, introduced in the 1990s.

Nowo’s machine range covers the entire production process from bale opening to weighing and filling, and complete production lines are tailored to the specific needs of customers. The company can also deliver individual machines such as bale openers, cards, cross-lappers, pickers, mixing devices, material silos, sucking devices, anti-static units etc. Seven patents cover the company’s technologies.

Founded in 1977, ACG Kinna Automatic, based in Skene in Sweden, specialises in customised and cost-efficient solutions for the production of pillows and quilts. All of its design, manufacturing and final line testing is carried out in Sweden and the reliability and longevity of its machines has earned it the trust of the world’s largest furniture and home decoration retailers and Europe’s largest manufacturer of pillows and duvets, among many customers.

Members of TMAS – the Swedish textile machinery association – are proving instrumental in pioneering new sustainable processes for the dyeing, finishing and decoration of textiles.

The wasteful processes involved in these manufacturing stages are only one component in the development of viable circular supply chains for textiles that are now being established in Sweden.

At the recent Conference on Sustainable Finishing of Textiles, held across three separate afternoons on September 30^th, October 1^st and October 7^th, delegates heard that Sweden will introduce extended producer responsibility (EPR) for waste textiles and clothing at the beginning of 2022, ahead of the adoption of a similar European Union-wide EPR system in 2025.

New fibers
Swedish companies are also active in the development of new fibers derived from waste clothing, building on the country’s legacy leadership in pulp and paper production.

At the Sustainable Finishing of Textiles Conference, however, it was said that all of the environmental gains made by such sustainable new fibers can potentially be cancelled out in the further processing they are subjected to – and especially in resource-intensive conventional dyeing, finishing and decoration.

TMAS members Baldwin Technology and Coloreel have both developed solutions to address this issue.

TexCoat G4
During the conference, Baldwin’s VP of Global Business Development Rick Stanford explained that his company’s TexCoat G4 non-contact spray technology significantly reduces water, chemistry and energy consumption in the finishing process. It consistently and uniformly sprays chemistry across a fabric surface and applies it only where needed, on one or both sides.

Instant coloring
Coloreel’s CEO Mattias Nordin outlined the benefits of his company’s technology which enables the high-quality and instant coloring of a textile thread on-demand and can be paired with any existing embroidery machine without modification. This enables unique effects like shades and gradient to be achieved in an embroidery for the first time.

Founded in 1952, Svegea of Sweden – a member of TMAS, the Swedish textile machinery association – has over 60 years of experience in exclusively designing, manufacturing and installing high quality collarette band cutting machines worldwide.

These are used by garment manufacturers around the world for the production of tubular apparel components such as waistbands, cuff and neck tapes and other seam reinforcements, such as Triteks Trejd.

Founded in 1994, this family-owned business employs over 280 people at its plant in Prilep, North Macedonia, where high quality cotton fabrics are expertly converted into the products of the Tritex Underwear brand.

The Prilep operation encompasses the processing of fabrics, design, cutting, sewing, quality control and packing in a fully integrated workflow.

With around 200 sewing machinists, the Tritex product range encompasses briefs, boxers, slips, t-shirts, pyjamas and body slips which are primarily sold to countries within the European Union, as well as the domestic market.

The company has also just completed the digitalisation of its full production via the in-house DPC-SYS system, installing around 200 industrial PCs linking each of its workstations and departments.

Triteks Trejd currently operates three of the latest Svegea collarette cutting machines and is highly satisfied with their performance, as well as the service provided by the Swedish company.
