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.

More and more brands are actively speaking up against the use of PFAS chemicals in products and supply chains. ChemSec’s corporate initiative the PFAS Movement was started in 2020, with the aim of creating a network of companies that would like to see PFAS chemicals regulated more efficiently. As of September 2021, 50 companies have joined the movement.

PFAS, short for per- and polyfluoroalkyl substances, is a chemical family consisting of almost 5,000 industrially produced chemicals. In manufacturing, PFAS are favored for their durability and well-functioning properties. They provide features such as non-stick, water repellency and anti-grease to many types of everyday products, including cosmetics, food packaging, frying pans and clothes, just to name a few.

Lately, more and more reports have been suggesting that PFAS are a serious problem. Human epidemiological studies have found associations between PFAS exposure and a number of health disorders.

One of the biggest challenges connected to PFAS is that, with very few exceptions, they are perfectly legal to use. This means that the brands and retailers who want to stop them from being used as ingredients in their products have very limited ways of communicating this in the global supply chain. As long as there is not a restriction in place, suppliers will continue to use these very effective chemicals in manufacturing. That’s why companies act together with a unified voice, like in the case of ChemSec’s PFAS Movement.

• 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.

International technology Group ANDRITZ will be presenting its innovative nonwovens production and textile solutions at INDEX20 in Geneva, Switzerland, from October 19 to 22. The broad ANDRITZ product portfolio covers state-of-the-art nonwovens and textile production technologies such as air-through bonding, needlepunch, spunlace, spunbond, wetlaid/WetlaceTM, converting, textile finishing, airlay, recycling, and natural fiber processing.

One highlight at INDEX will be the new member of the ANDRITZ Nonwoven division: ANDRITZ Laroche – a company that has been an important partner for ANDRITZ in the field of fiber preparation for drylaid nonwovens for over 10 years. ANDRITZ Laroche is a leading supplier of fiber processing technologies such as opening, blending and dosing, airlay web forming, textile waste recycling, and decortication of bast fibers.

One focus of this product range is complete recycling lines for post-consumer and industrial textile waste to produce fibers for re-spinning and/or nonwoven end-uses. Customer awareness and regulations are pushing clothing brands to recycle their textile waste in their own products. Recycled fibers can also be used in the nonwovens industry for various applications, such as automotive, insulation, mattresses, and furniture felts.

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.

To ensure product protection and prevent brand piracy, GRAFE has developed a simple and elegant solution that also offers a high level of security. The basis is special markers. "The highly complex pigments with special physical properties designed for this purpose are used in minute quantities within the plastic matrix. With an appropriately calibrated detector, products equipped with them can thus be read and authenticated," explains Business Development Manager Florian Ludwig. At the same time no changes in properties can usually be observed. The detectors can use an LED display to check within seconds whether the unique marker is contained in the product and whether this item is the original product.

In general, there are two options: x ray and light fluorescence, i.e. fluorescent X-rays or light. With the first option, the base color has no influence (not even black) and the customer benefits from low addition dosage and batch price, but this method requires higher investment. "With light fluorescence, on the other hand, detection is done by a measuring device, which is preconfigured by our partner or by us directly. Different types are available, from handy hand-held measuring devices to stationary office solutions to inline spectrometers, in order to have a control take place directly during production," Ludwig explains. With this method, the masterbatch dosage is based on the base color, among otherv things. The method of operation is fast and simple, and the necessary investment is also manageable.

From injection molding and extrusion to transparent and fiber applications, almost all areas of plastics processing come into question.
