From the Sector

Alchemie Technology, an innovator of low energy, waterless, textile dyeing and finishing technology, is calling on COP26 leaders to support the global fashion industry in the adoption of new manufacturing technology, which will dramatically reduce carbon emissions and fashion’s impact on climate change.

While the fashion industry is one of the most polluting on the planet, second only to oil and gas, and greenhouse gas emissions from textile dyeing at around 3% of global emissions outweigh that of all international flights and maritime shipping combined, it is an industry that can also reduce CO2 emissions the fastest, just by changing the way it dyes fabrics.  

Fabric dyeing is the most polluting part of fashion and activewear manufacturing, involving industrial scale dye baths and huge amounts of dye chemicals, steam, electrical power, and consequent high CO2 emissions.  Repeated washing of the dyed fabric, required to remove dye residue, is responsible for 20% of the world’s wastewater pollution and excess dye is discharged into waterways, affecting the health of some of the world’s poorest communities. In more regulated areas, water pollution is reduced through reliance on energy intensive water treatment plants.

However, an environmental step change can be achieved by adopting new digital technology that can dye fabrics with an 85% reduction in energy consumption and a dramatic 95% reduction of the 1.3 trillion litres of water currently used by the industry each year.

For example, dyeing one polyester shirt using current methods generates 4.5 litres of wastewater and produces 0.17 Kg of CO2, compared to low energy digital technology, which uses less than 0.2 litres of water and reduces carbon emissions to 0.03 Kg.  Multiply these numbers by the billions of garments dyed each year and the scale of the environmental problem, if nothing changes, is clear to see. Equally, the amount by which the textile industry can improve its carbon footprint is dramatic and can be done quickly if action is taken now.

Picanol has introduced its latest generation of airjet and rapier weaving machines, which have been called the “Connect” generation. These new generation weaving machines focus on connectivity and an increased level of data availability. With this new generation, Picanol is launching several new functionalities such as a digitalized Gripper stroke setting, Gripper tape monitoring, Climate control, Shed angle measurement, and fully integrated Power monitoring.

“Following the successful launch of our digital platform PicConnect earlier this month, we have now released a new generation of weaving machines, which are known as the Connect generation. Our Connect generation weaving machines can provide the correct data and are loaded with new and never-before-seen functionalities. This is clear proof that for Picanol “Driven by Data” is not just a slogan but a commitment. Not only have these innovations allowed us to make big improvements when it comes to our four design principles – Smart Performance, Sustainability Inside, Intuitive Control, and, of course, Driven by Data – but when combined with our new digital platform they will allow you to amplify your own intuition.” comments Johan Verstraete, Vice President Weaving Machines.

From now on, the range of Picanol weaving machines will have the “Connect” suffix. For the airjet weaving machines, this means: OmniPlus-i Connect and TerryPlus-i Connect, while for the rapier weaving machines, this means: OptiMax-i Connect and TerryMax-i Connect. These new machines are built around Picanol’s four main design principles:

Smart Performance
On the OptiMax-i Connect, Picanol has introduced a lubrication monitoring sensor in combination with a temperature sensor. The combined data they provide allow the user to make sure the gripper tapes are in optimal condition for maximum performance. As an option, a gripper stroke measurement sensor is also available. This not only dramatically simplifies the setting of the gripper stroke, but also enables the user to realize higher machine speeds when weaving reduced widths – a pure extra output combined with more user-friendliness.

Sustainability Inside
Even though it was 25 years ago that the Sumo Drive concept was launched, it remains the most powerful, versatile and energy friendly machine drive available. And it has been even further optimized. It features an optimized sheet metal package for lower energy consumption, optimized oil cooling circuit for a better performance and a built-in temperature monitoring. Moreover, the Connect machines can be equipped with a Power monitoring module, which allows the user to keep track of the power consumption of each machine over time. Every Connect machine also has a built-in ambient temperature and humidity sensor, which will help to optimize the climate control in the weaving shed at the lowest cost. And as raw material is the biggest cost factor, each machine can also be equipped with raw material use monitoring.

Driven by Data
As the machine has more sensors than ever before, it also generates more data. To enable a fast reaction to all these sensor data, the BlueBox control unit has been further optimized: better heat management guarantees short reaction cycles combined with the long lifetime of components. To have a good view of all of the data generated, a special sensor dashboard screen is available in the BlueTouch display: with a simple touch of the screen, the current and historical power consumption, temperature, humidity, material consumption, and – on the OmniPlus-i Connect – also the air consumption, can be monitored. The BlueTouch display is now also equipped with an Action center, an electronic logbook where all actions such as maintenance interventions can be logged or scheduled beforehand. The machine manual is now available on the BlueTouch display, and with the context-based help function the help pages related to the operation the user wants to perform appear with one touch of his/her fingertip. The built-in web browser even allows the user even to consult, for example, tutorial videos on the web to guide them through a setting procedure.

Intuitive Control
The Connect generation was designed to focus on what really matters: weave the highest possible grade A fabrics at minimal costs. A large set of tools have been installed to facilitate this goal. One of the most remarkable ones is the Harness frame stroke measurement – until recently, it was only available on the revolutionary SmartShed, but it is now also available on the cambox and dobby machines. Combined with the shed visualization and simulation, it offers a quantum leap in terms of optimizing the user’s shed settings without losing any time or taking any risks. The colors of the programmable Smart signal lights with stop timing functionality are now repeated around the push buttons, allowing even better visibility and the prioritization of interventions by the weaver. A full-fledged Access control system not only limits the access to certain pages and settings depending on the user, but also allows a tailored dashboard to be established for each user profile.

Penn Textile Solutions GmbH is one of the world's leading manufacturers of elastic fabrics for under-wear, corsetry, sportswear and swimwear, as well as highly functional textiles for technical applications. The fully integrated company with its own warping, circular knitting, warp knitting, dyeing and finishing facilities currently employs around 150 people.

Penn has long relied on Mahlo
Penn has relied on the cooperation with Mahlo for years. The manufacturer of measuring, control and automation systems for web-shaped goods has decades of experience in the field of process control. Until the summer of 2020, the textile manufacturer had been using a basis weight measurement system in the stenter frame outlet with beta radiation and manual control. "When the krypton preparations had passed their half-life, we had to make a decision: Exchange or replace the system right away", says operations manager Franz Schütte. They sat down with Mahlo representatives and looked for the best solution. Since the systems had already reached a high operating age and the measurement was limited to the basis weight, a new concept was decided upon. "Mahlo made us the best price-performance offer." The new system should be even more efficient and easier to operate for the special makes..

The compression zones of the functional fabric create corresponding distortions within the textile surface in its raw state, which have to be smoothed out in the fixing process. This work is now taken over by a process control system. The Mahlo Famacont PMC-15 with two measuring points automatically controls the leading of the stenter frame by continuously and contactlessly determining the mesh density. In addition, the Patcontrol PCS-20 process control system ensures that the dimensions of the different zones are recorded and also automatically controlled. "The previous beta-radiation facility was not able to collect this kind of data," explains the Penn operations manager. Another important aspect for the textile manufacturer: the complete and costly radiation protection is no longer necessary with the new systems.

Despite very good experience with Mahlo in the past, every change naturally involves a risk. Penn did not have to rely on theoretical considerations, however, but carried out tests in advance with appropriate sample material in the Mahlo test laboratory. The results convinced the decision-makers.

With its resource-saving dyeing technology, We aRe SpinDye takes place in H&M's latest Innovation Stories collection called Co-exist.

The use of We aRe SpinDye's technology contributes to reducing both water consumption and CO2 emissions, which in turn leads to a lower impact on the world's ecosystem and creates conditions for our co-existence with nature.

Up to 24% of a garment's entire climate footprint occurs during dyeing. We aRe SpinDye's technology can reduce the consumption of the earth's resources in textile production. On average, the reduction of water is -75%, chemicals -90% and energy consumption and CO2 emissions -30%.

In just one year, the clothing industry uses 9 billion cubic meters of water (which is in line with the annual need for drinkingwater for the entire population of our planet) and 168 million tons of process chemicals to dye fabrics. We aRe SpinDye now hopes that more players in the industry will pay attention to the ways that are available when it comes to resource-efficient dyeing process and quickly implement this technology in their production.

"The enormous resource consumption in the dyeing process is a global problem that must be addressed on a broad front. It is therefore inspiring to work with major brands with an organization that is sensitive to cutting-edge expertise and at the same time shows a willingness to work together to achieve common goals", says Andreas Andrén, CEO of We aRe SpinDye.

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.

RadiciGroup's nonwoven innovations are on display at the INDEX trade fair, to be held from 19 to 22 October 2021 in Geneva, Switzerland. Active in the spunbond production business for more than 30 years with the dylar® product line, the Group is introducing Respunsible®, a reduced environmental impact spunbond made from recycled polypropylene, and radimelt™, the brand name for the Group’s line of meltblown nonwovens and composite materials (e.g., SMS).

Respunsible® is a spunbond made from recycled polypropylene, a material appreciated for its chemical properties and its versatility. Its high technical performance makes it suitable for any application, even the most demanding ones in terms of resistance and duration.

Radimelt™ is the brand name identifying the Group’s meltblown nonwovens, materials used for the manufacture of protective face masks and other personal protective equipment (PPE). This nonwoven fabric has excellent filtration performance even for microscopic particles, such as viruses, and ensures breathability and protection.

Reifenhäuser Reicofil will exhibit at the world's leading nonwovens trade show INDEX in Geneva from October 19 to 22, 2021. Under the slogan "Living Nonwovens", the nonwoven line specialist will showcase solutions for the production of sustainable nonwovens for a wide range of applications.

Sustainable nonwoven production starts with the amount of material used - the less raw material needed, the better. The "Reicofil 5x" line series is specialized in this application and achieves fabric weights of 8 gsm (grams per square meter) or even less through efficient downgauging, even on 1000 m/min Composite lines containing 3 Spunbond beams.

In addition, Reicofil customers can reduce the use of fossil raw materials on request by processing biobased raw materials as an ecological alternative - for example for diapers. The topsheet material, made of bulky, soft, and industrially compostable high-loft nonwovens, meets maximum hygiene requirements at the same time.

For industrial applications, high-strength nonwovens can be processed even from up to 90% PET flakes from post-consumer waste. This is how Reicofil shows ways to combine sustainability and high-performance nonwovens.

In the medical sector, the line manufacturer will also be exhibiting its leading solutions for high-barrier medical protective clothing. In addition, meltblown nonwovens for face masks - still in great demand in many regions due to Covid - provide reliable safety and are helping to combat the pandemic worldwide. Reicofil technology therefore guarantees maximum safety, with filtration efficiencies of up to 99% (N99 / FFP3 standard), minimum quality fluctuations, and extremely high line availability at the same time.

With the current RF5 machine generation, Reicofil also sets benchmarks in terms of quality, performance, availability, efficiency, and machine intelligence - for challenging applications in hygiene, medical, and industrial sectors.
