From the Sector

Global energy consumption reached a record high in 2019, following a 40-year trend for rapidly increasing energy demand that was only halted by the Coronavirus pandemic. It’s estimated that more than 80 % of this energy is still generated from fossil fuels that produce CO2 emissions and contribute to climate change. Renewable energy offers a solution to this problem, but saving energy whenever possible is an even more effective approach. That are the motives for Trützschler to develop the intelligent card TC 19i, which sets a new benchmark for energy-efficient carding.

The intelligent Trützschler card TC 19i features the unique T-GO gap optimizer, which continuously and automatically monitors and adjusts the carding gap to an ideal position during production. Innovative drive- and air technology further reduce energy consumption of the TC 19i.

The most energy-intensive elements in a carding machine are the drive, the dust suction process and the compressed air system. Permanent suction is needed to remove dust and cotton waste in key places. Smart optimization of these areas has made the intelligent card TC 19i a benchmark for energy efficiency in carding because it uses less electricity, lower suction pressure and less compressed air than other machines, while providing the highest production rates currently available on the market.

In a head-to-head comparison between the TC 19i and a high-performance card from a competitor, the TC 19i consumed at least 10 % less energy per kilogram of material produced when manufacturing rotor yarn from a cotton and cotton waste mix. The compared energy values included electric power consumption and energy required for suction and compressed air and were measured in both cards at the same production of 180 kg/h. A 10 % reduction in energy per kilogram of sliver produced, as proven here by TC 19i, can have a significant impact on a spinning mill’s profitability; annual savings worth a five-digit sum are frequently possible, depending on factors such as the output of the mill. The customer trial also showed TC 19i’s excellent reliability at the customer’s usual production rate of 180 kg/h, and even demonstrated stable performance at 300 kg/h in the same application. Because the TC 19i with T-GO gap optimizer realizes maximum production rates at no compromise in quality, manufacturers can reduce their energy demand and investment costs drastically: Less machines are needed to achieve the desired output, and energy consumption per production is reduced.

This improvement was made possible by a long and sometimes challenging innovation process involving mathematical models of air flows, as well as flow simulations and prototypes. By combining the final flowoptimized parts in the TC 19i, Trützschler’s experts have developed a card that operates with suction pressure of just -740 Pa and with an air requirement of only 4200 m³/h. This translates into 40 % less energy demand for air technology compared to the latest high-performance competitor model.

• 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.

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.

• Introducing TexCoat G4 to US textile industry
• Non-contact precision spray fabric-finishing system enhances sustainability and process control

Baldwin Technology Company Inc. will be showcasing its TexCoat G4 non-contact precision spray fabric-finishing system at the Techtextil North America trade show, held Aug. 23 to 25, in Raleigh, North Carolina.

With extensive sustainability benefits, unprecedented tracking and process control, and Industry 4.0 integration, the TexCoat G4 provides consistently high-quality fabric finishing, with no chemistry waste, and significantly reduced water and energy consumption.

Baldwin’s innovative non-contact spray technology eliminates chemistry dilution in wet-on-wet processes. The TexCoat G4 consistently and uniformly sprays chemistry across the fabric surface and applies it only where needed, on one or both sides.

Customers can expect no bath contamination during the finishing process, as well as minimal downtime during changeovers, which are made easy with recipe management that includes automated chemistry and coverage selection. The TexCoat G4 also enhances sustainability by wasting no chemistry during color, fabric or chemistry changeovers, and because only the required chemistry volume is applied to the fabric, wet pick-up levels can be reduced by up to 50 percent—leading to 50 percent less water and energy consumption.

Furthermore, in single-side applications, drying steps can be eliminated for various textiles, including those that are back-coated and laminated, thereby streamlining and simplifying the production process.

International technology Group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at ANEX/SINCE 2021 in Shanghai, China, from July 22 to 24, 2021. The product portfolio covers state-of-the-art nonwovens and textile production technologies such as air-through bonding, needlepunch, spunlace, spunbond, wetlaid/Wetlace, converting, textile finishing, airlay, recycling, and bast fiber processing.

Among the largest end-use markets for nonwoven products are materials for durable uses. Interior linings for cars, materials for construction, geotextiles, synthetic leathers for clothing and furniture, carpeting, filtration and many other industries rely on the use of nonwovens produced using the needlepunch method.

ANDRITZ Nonwoven’s processes play a pioneering role in the production of biodegradable materials. For many years, ANDRITZ has offered different processes, like spunlace, Wetlace and Wetlace CP, all with one goal in mind: Elimination of plastic components while maintaining the high quality of the desired product properties. Such processes achieve 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, thus meeting customers’ needs exactly as well as supporting the strong tendency to move away from plastics and synthetics.

The latest development in this field is the ANDRITZ neXline wetlace CP line. This process combines the benefits of two forming technologies (inline drylaid and wetlaid web forming process) with bonding by hydroentanglement. Natural fibers, like pulp or viscose, can be processed smoothly and generate a high-performance and cost-efficient wipe that is fully biodegradable and plastic-free.
