From the Sector

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.

• “The Atlas MAX technology provides a marked improvement in quality; it gives you that edge and something different."

Kornit Digital Ltd. (NASDAQ: KRNT), a worldwide market leader in sustainable, on-demand, digital textile production technologies, announced today that Peterborough, United Kingdom-based print provider Snuggle has installed two Kornit Atlas MAX systems for superior versatility in their on-demand fulfilment production operations. A Kornit customer since 2017, the addition of Kornit’s most advanced direct-to-garment production systems reflects Snuggle’s sustained profitability and growth since that time.

Kornit Atlas MAX is the first digital direct-to-garment production system to feature XDi technology, which empowers users to simulate embroidery, dye sublimation, vinyl heat transfer, and 3D graphic effects with one single-step platform, using Kornit’s eco-friendly NeoPigment™ inks. Delivering superior graphic detail, consistent retail quality, and low and consistent cost per print to ensure profitability in any quantity, the system is engineered for adaptability to long-term automation needs, which helps businesses like Snuggle address the ongoing labour shortage.

With seven Kornit Digital systems in total, Snuggle is now able to produce up to 12,000 units daily, and has expanded its production space more than threefold since first investing in the technology. While the business does include an embroidery unit, Snuggle rejected screen printing due to its slow setup process, inefficient sampling for bulk orders, and the inability to generate profit from smaller custom orders. Furthermore, digitally-enabled production on demand was critical to their adapting when the pandemic economy caused many customers to cancel bulk orders suddenly.

Reifenhäuser Cast Sheet Coating - specialists for cast film, sheet extrusion and extrusion coating lines - will showcase a new production process for cost-effective film/nonwoven composites with an exceptionally low grammage at ICE (International Converting Exhibition) Europe. The leading international trade show for paper, film, and foil conversion and processing will be held at Messe München (Munich trade fair center) from March 15-17, 2022.

The Covid-19 pandemic and current supply shortages have exposed the dependence of companies on global supply chains. This situation is both a warning signal and an opportunity to boost and reorganize the local production of semi-finished products from the ground up. Reifenhäuser Cast Sheet Coating has now developed a trend-setting production process termed Ultrathin Coating, in particular for the sector of medical protective clothing. The process will permit customers to produce particularly lightweight film/nonwoven composites with greater cost efficiency and, as a result, more competitively. The patent-pending process has several advantages: It cuts film grammage by 66%; material consumption in the overall composite is reduced by 28%; and it slashes costs by up to 34% compared to conventional semi-finished products. Significant cost savings are achieved in various ways, for example, by replacing hotmelt adhesives, which reduces line maintenance to a great extent at the same time.

Mark Borutta, Sales & Marketing Specialist bei Reifenhäuser Cast Sheet Coating, erklärt: „Wir erleben derzeit einen nachhaltig wachsenden Mehrbedarf für medizinische Schutzbekleidung verbunden mit einer Rückholstrategie für lokale Produktionskapazitäten. Vor diesem Hintergrund erzielen Produzenten mit ‚Ultrathin Coating‘ einen schnellen Return on Invest und hohe Profitabilität – auch bei einer Produktion innerhalb Europas.“ Die Vlies-erfahrene Schwesterfirma Reifenhäuser Reicofil –führender Hersteller von Vliesstoffanlagen – hat die Entwicklung unterstützt.

Mark Borutta, Sales & Marketing specialist at Reifenhäuser Cast Sheet Coating, explains: "We are currently experiencing a sustained increase in demand for medical protective clothing combined with a return strategy for local production capacity. Against this backdrop, producers achieve a fast return on investment and high profitability with Ultrathin Coating - even when production is based in Europe." The sister company, Reifenhäuser Reicofil, an experienced and global leading manufacturer of nonwoven lines, provided their support to the development.

Even if manufacturers already produce medical protective clothing and prefer to handle the coating process internally in the future instead of importing the necessary composites, it is worthwhile to set up an in-house production facility. In either case, the investment in Ultrathin Coating usually pays for itself in less than 12 months. The lower material input also reduces the consumption of fossil raw materials and this in turn responds to the increased demand for more sustainable products.

Baldwin Technology Company Inc.—a one-stop source for high-performance coating, curing, treating, cleaning and inspection solutions—will feature pioneering new technology for optimizing converting, printing and film-extrusion processes at ICE Europe, which will be held at the Munich Trade Fair Centre in Germany from March 15 to 17.

Baldwin’s innovations can help customers meet the burgeoning demand for film and packaging amid the many economic and logistical headwinds challenging the industry. In addition, Michael Stürmer, Baldwin’s Director of Strategic Accounts, will present “Back to the Future: The 100-year-old processautomation solutions the corrugated industry has overlooked, until now!” at 11:30 a.m. March 17 during the International Exhibition for the Corrugated and Folding Carton Industry, held in the same location as ICE.

Baldwin provides converters with expertise and a broad range of market-leading innovations that offer superior print results, and enhance the economic and environmental efficiency of print production processes. Solutions on display at ICE will include automated cylinder cleaning systems, corona surface pretreatment systems, LED-UV curing and IR-drying systems, hot-air dryers, rotary spray systems, and technologies for color management and defect detection, all of which increase productivity, reduce waste, improve working conditions and provide full control of producing flawless products.

Automatex, a member of TMAS, the Swedish textile machinery association, has recently supplied a number of its latest Industry 4.0-enabled automatic fitted sheet systems to customers in Europe.

The Automatex model FDC-77735-B90D-EC system enables the full production and folding of six fully-fitted sheets per minute – approaching 3,000 an average shift – overseen by a single operator and eliminating many of the repetitive cut and sew operations of the past. Elastics insertion –  usually a highly complex labour-intensive task – can be on all four sides of the sheet, two, or simply within the corners, depending on customer specifications.

Fabric is fed directly from the roll, with precise edge guiding and tension control, into a length-wise hemming and elastics insertion section with adjustable tension devices, before being measured and cross cut in an accumulator. It is then transferred to the cross hemming section, again with elastics insertion.

A side drop forming unit pre-forms the sheet before it is transported by a multi-axis clamp conveyor system to the corner sewing section, consisting of left and right overlock sewing heads. Here, the corners are robotically sewn at 90 degrees and labels are also attached when specified.

Further customised systems for folding are also supplied as required.

BB Engineering GmbH (Germany) delivers a melt filter for recycling PET flakes to polyester manufacturer Indorama Polyester Industries (Thailand). Indorama will be using the type NSF38 filter in its recently assembled recycling system in order to produce rPET granulate from flake PET bottle waste. The NSF38 filter enables continual filtering – in other words, the system switches from one filter to the other during the process without the need for conversion shut-downs. The filter allows the processing of consumer waste for example, in the form of shredded PET bottles into new, high-quality rPET granulate. This granulate is subsequently processed into manmade fibers in spinning systems.

The NSF38 is a switchable filter with a filter surface area of ap-prox. 16 m2 on each side, with throughputs of between 1,000 and 1,900 kg/h. The filter inserts each contain 19 pleated filter candles (60 x 1,000mm Ø). The filter medium comprises a sin-tered metal fiber nonwoven with a filtration fineness of 25 μm. This ensures that the melt remains free of contaminants and gel particles, which in turn enables the production of high-quality end products.

Over 600 delegates from 58 countries subscribed to the latest VDMA textile machinery webinar on sustainable dyeing held on February 3rd, 2022 – a record since the monthly online series started in June 2020. The webinar, entitled ‘Resource-saving in Textile Processing – Continuous Dyeing and Washing’, involved the three companies Monforts, DyStar® and Goller.

In outlining the capabilities of Monforts Thermex hotflue lines for the Econtrol® continuous dyeing process, the company’s Textile Technologies Engineer Jonas Beisel observed that the current industry focus is very much on cleaner processes and products in accordance with the Corporate Social Responsibility (CSR) commitments of the major fashion brands, and with further regulations to be expected.

Cellulosics
Econtrol® is a continuous process for the dyeing of woven cellulosic fabrics that has already been well proven on the market, with over 150 Monforts Thermex lines already in operation at mills worldwide.

Reactive dyestuffs are fixed into the fabric in a one-step dyeing and drying process with a controlled combination of steam and air. The entire pad-dry process takes just two-to-three minutes at a temperature of between 120-130°C and a relative humidity volume of 25-30%.

Benefits
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.

Complementary services and systems
Complementing the Monforts presentation during the webinar, Bertram Seuthe, Global Business Development Manager at DyStar, outlined the importance of specific Levafix® /Remazol® reactive dyes and Dianix® disperse dyes for sustainable dyeing processes such as Econtrol®, Cadira® Continuous and CPB knit. In these processes Sera® auxiliaries are also employed for optimised wash-off results.

Guido Seiler, Area Sales Manager at Fong's Europe, also introduced the latest developments of the Goller brand for the washing process, which can reduce water consumption by between 10 to 20%, as well as reductions in both heating energy and waste generation, depending on the specific fabric construction and required shade.

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.”
