From the Sector

For more than 70 years BRÜCKNER has been in the construction of drying and finishing lines for the textile and nonwovens industry. In the nonwovens sector, the company supplies worldwide thermofusion ovens, dryers, coating and heat-setting lines. On the IDEA 2022 trade fair in Miami, USA, BRÜCKNER presents together with its American representation FI-TECH new machine concepts and solutions for different applications in the mentioned fields.

The production of nonwovens always requires a bonding process after the nonwovens formation, where the loosely laid fibers are bonded to a resilient fiber composite. For this purpose, depending on the process, different ovens and dryers are used. BRÜCKNER supplies the necessary lines for all applications. The production program is completed by different impregnation and coating units as well as slitting and winding equipment. BRÜCKNER's customers produce geo nonwovens, filter media, hygiene and medical textiles or different fabrics for the automotive and transport industry

For the production of highloft nonwovens the double-belt thermofusion oven SUPRA-FLOW BX is used. This oven system operates according to the air-through principle and can be perfectly adapted to the product requirements in terms of flow speed, flow direction and temperature on a field-by-field basis.  
The SUPRA-FLOW BX can produce nonwovens up to a thickness of 280 mm and a basis weight of max. 8 kg/m². The available working widths vary between 2400 and 5200 mm at production speeds of up to 100 m/min.  
For geotextile projects, the POWER-FRAME stenter is usually used, which impresses with its uniformity in terms of temperature distribution as well as productivity. In addition, the fabric can be stretched in a targeted manner by transporting it in the stenter chain. This has a controlled influence on fabric width, fiber orientation and fabric shrinkage. Working widths of up to over 7 meters are not uncommon with geotextile finishing systems.

Altri has awarded AFRY engineering, site selection and integrated environmental authorization services assignment for a greenfield textile fiber factory in Spain. In addition, AFRY will support Altri to conceive, create and implement foundations for Industry 4.0 technologies in this new plant.

The demand for sustainable textile fibres is growing quickly globally. To support this growth, the Portuguese pulp producer Altri has become the industrial partner to public-private consortium Impulsa (Society for the Development of Strategic Projects of Galicia) as the lead investor and technologist to study the wood-based textile fibers biofactory exclusively. This biofactory will use Galician wood as the primary raw material together with recycled remains from the textile industry to produce dissolving pulp and Lyocell fibre. The plant will be designed based on the best available techniques (BAT), best environmental practices, as well as cutting-edge proven technologies and the production will be fossil-fuel-free. The project is expected to benefit from the “Next Generation EU” program.

Altri is responsible for designing and developing the biofactory project to transform wood into a textile fiber, evaluating site locations and exploring alliances with the entire value chain. Altri has assigned AFRY to support the project development and planned project implementation.  

The industrial biorefinery to be built from scratch will be able to provide the textile cluster of the Iberian peninsula with sustainable cellulosic fibers, contributing to the strengthening of the circular economy and decarbonisation of an important economic sector such as the textile sector.

AFRY has been involved in the project development from the very early stages. AFRY supported the project concept idea initially developed by Altri and led the preliminary feasibility study. A multi-disciplinary team of AFRY’s engineering and consulting experts is currently supporting Altri on the site selection activities, engineering and permitting processes.

For the second time in a row, the speciality viscose fibre manufacturer Kelheim Fibres was awarded a place on the podium at the Cellulose Fibre of the Year Awards. The concept for sustainable menstrual underwear made from Kelheim’s functionalised speciality fibres achieved third place. Kelheim Fibres thus emerges from the competition as the most innovative fibre manufacturer.

Project manager New Business Development Natalie Wunder presented the promising concept from Kelheim at the International Conference on Cellulose Fibres: "We have been able to use our experience as a long-established supplier for the tampon industry to develop further sustainable solutions in the feminine hygiene sector, in this case reusable menstrual underwear. As an innovation pioneer, we are thus helping to break the taboos that surround the topic of menstruation. We offer women the choice between different environmentally friendly products which also offer high levels of performance - depending on what fits their lifestyle."

For the next step, the commercialisation of the concept, Dr Marina Crnoja-Cosic, Director New Business Development at Kelheim Fibres, puts her trust in the proven open innovation approach: "We want to bring partners from the entire value chain together. By bringing in our joint expertise, we can significantly accelerate the path from idea to finished product in the market. At the same time, through open dialogue, we ensure that the concept works seamlessly from fibre through processing to the final product.

• 76 KL/Day water saving by optimizing pH analysis process in dye vessels
• A step closer to achieving the ‘Huntsman Horizon 2025’ goal
• Potential savings of over Rs 10 crore or USD146,000 annually from the project

Huntsman Textile Effects, the global leader in innovative and environmentally sustainable dyes, chemicals, and digital inks, has successfully implemented a water conservation process to improve water efficiency and reduce net water usage at its Baroda facility, which is located in the western region of India. The initiative undertaken at the plant aims to save around 76 kilo liters of Reverse Osmosis water per day by modifying the phase sequence in the pH measurement program.

Water is used extensively throughout textile processing operations. The amount of water used varies widely in the industry, depending on specific processes operated at the plant, equipment used, and policies concerning water use. This conservation project at the Baroda Plant will have a potential savings of Rs 10 crore or USD146,000 a year for the organization.

Speaking on the development, Mark Devaney, Vice President Manufacturing and Operations Excellence, Huntsman Textile Effects said, “At Huntsman, we recognize the important role we play in creating a more sustainable future and are committed to the well-being of the communities where we operate, and the protection of the environment. We are continually looking for ways to improve the environmental footprint of our manufacturing sites and have been implementing numerous projects in recent years to reduce our water usage.”

“The team has done a detailed assessment of the pH analysis process in dye vessels, mapping the existing water usage and potential conservation method. After a brief study and several brainstorming sessions, we were able to adjust the phase sequence, resulting in conservation of Reverse Osmosis water by almost 76 kilo liters of water per day.” said Kavishwar Kalambe, Site Director, Huntsman Textile Effects. “This project directly contributes to Huntsman’s Horizon 2025 goals to reduce net water usage at facilities in water-stressed regions,” he added.

Over 400 employees work hard every day to improve the environmental performance of Radici Yarn’s site. Through teamwork and continuous improvement in energy efficiency, Radici Yarn has obtained ISO 50001 Energy Management Systems certification, which attests to the organization’s commitment to contain and progressively reduce energy consumption.

Radici Yarn, one of the companies in the RadiciGroup Advanced Textile Solutions Business Area, is engaged in the production and sale of polyamide 6 polymer, PA6 and PA66 continuous filament and staple yarn, and other synthetic fibres, including products made of recycled or bio-based materials.

All the processes - polymerization and spinning (Villa d'Ogna plant), as well as warping and draw-warping (Ardesio plant) - are run under constant monitoring with the goal of achieving maximum energy efficiency and lower consumption. Both sites are powered by two hydroelectric power plants owned by Geogreen, a RadiciGroup partner and energy supplier. The share of energy consumption from renewable sources and reduced environmental impact (natural gas) sources  is constantly increasing.

The energy issue has always been a priority for Radici Yarn, whose products serve numerous sectors, including automotive, clothing and furnishings.

"Already at the beginning of the 1990s, Radici Yarn started investing in cogeneration, the simultaneous production of electricity and steam,” pointed out Laura Ravasio, energy manager of Radici Yarn SpA. “We have recently started up an advanced trigeneration plant – a highly efficient system that produces not only electricity and steam, but also chilled water for our production processes. One of the first results recorded in 2021 was a 30% reduction in water consumption. Thus, ISO 50001 certification seemed like the next logical step to take in formalizing a long-term approach to energy.”

The ISO 50001 certification, which is voluntary and valid for a period of three years, was added to the ISO 14001 Environmental and ISO 9001 Quality Management system certifications previously achieved by Radici Yarn.

The textile service provider Hohenstein has successfully extended its accreditations as a testing laboratory and certification body to include FFP (Filtering Face Pieces) respiratory masks in accordance with DIN EN 149, thus completing its portfolio in the textile mask sector. The necessary functional and safety tests on community masks, medical masks and FFP respiratory masks contribute to consumer safety. In addition, Hohenstein has not only been a member of the German Mask Association since September 2021, which pools the expertise of all mask manufacturers and suppliers in Germany, but also supports the Quality Working Group with its expertise in the field of textile protective clothing.

Filtering Face Pieces are primarily used for the self-protection of the wearer and are intended to protect from harmful aerosols, particles and droplets. There are different protection levels for FFP respiratory masks (FFP 1-3), depending on how well they retain liquid and solid particles. In occupational safety, they are part of personal protective equipment (PPE) and fall under category III. Their protective function is specified throughout Europe by the DIN EN 149:2009-08 standard, which requires laboratory tests and practical performance tests with test persons. The Hohenstein testing laboratory carries out reliable proof of the safety of FFP respiratory masks in several test steps:

• Through visual inspection, the Hohenstein experts assess the correct labelling, the comprehensibility of the enclosed instructions for using the masks, as well as the functionality and packaging.   
• Laboratory tests can determine, among other things, breathing resistance, filter medium transmittance and inward leakage. The practical performance of FFP respiratory masks is assessed through realistic tests with test persons.
• Test persons can also be employed to assess other parameters such as skin tolerance, field of vision or headgear comfort.
• Optional tests, such as testing FFP respiratory masks for harmful substances, complete the safety verification.

Since the beginning of the pandemic, a particularly large number of FFP respiratory masks with doubtful and even false labelling have been in circulation, so reliable and neutral testing and certification of these products is essential. Hohenstein, with its many years of extensive experience in the testing and certification of personal protective equipment, thus offers the ideal service for customers who value testing quality "Made in Germany".

As a testing laboratory for medical devices, Hohenstein also offers testing of medical face masks for their bacterial filtering performance, differential pressure as an indicator of breathing activity, microbiological purity and cytotoxicity, among others. Medical face masks fall under the Medical Devices Regulation 2017/745 and fulfil the requirements according to EN 14683. The testing service provider Hohenstein has already taken a big step towards safety and functionality with the introduction of its quality label for Tested Community Masks in June 2020 and also tests according to the first European Guideline for Everyday Masks, the CEN Workshop Agreement (CWA) 17553:2020.

• Evopreg® range expanded with unidirectional fibre-reinforced thermoplastic tapes

Composites Evolution, a developer, manufacturer and supplier of prepregs for the production of lightweight structures from composite materials, has announced the launch of a new range of unidirectional thermoplastic tapes, to sit alongside its existing line-up of Evopreg® prepregs. The first product families being launched are Evopreg® PA polyamide tapes, and Evopreg® PP polypropylene tapes, with further product lines expected as new customer requirements emerge.

Thermoplastic tapes, also known as thermoplastic prepregs, can be used in a wide variety of markets and applications, including flexible pipes for oil & gas and water transportation, pressure vessels (for example; hydrogen storage tanks and compressed natural gas tanks), and for providing local reinforcement to pre-formed components.

Marketing Director, Ben Hargreaves, explains further: “Our state-of-the-art manufacturing line gives us the capability to produce tapes on an industrial scale, using a variety of combinations of fibre and polymer. This is complemented by a pilot-scale line that allows us to carry out development trials, or manufacture small quantities of tape if required.”

“Because they can be repeatedly re-formed (via the application of heat and pressure), Evopreg® thermoplastic tapes are also very well-suited to multi-stage processing, meaning they are an excellent choice for producing hybrid structures, inserts or over-moulded components. In addition, this ability to be repeatedly re-formed opens the door to much easier recycling than is currently possible with thermoset composites.”

Archroma, a global leader in specialty chemicals towards sustainable solutions, and Jeanologia, a world leader in sustainable and efficient technology development, joined forces to launch an eco-advanced alternative to the denim fabric washing process, including in some cases the mercerization, one of the most water-intensive and pollutant processes of denim fabric finishing.

It all starts with the spinning step where the cotton is turned into yarn. The second step is a pretreatment that will prepare the yarn for the dyeing step. The dyed yarn then goes through the sizing process, which is a treatment preparing it for weaving. At this stage, we have obtained a denim fabric that will go through a few more steps. First, the fabric may undergo a washing treatment or, in some cases, mercerizing treatment which consists of treating it with caustic soda in order to obtain a more lustrous, flat and less reddish blue and black denim.

In both traditional ways to clean the fabric, washing or mercerizing, multiple highly water intensive washings are required in order to restore optimal fabric pH and remove unfixed dyestuff and any undesired deposits or impurities from the fabric. One of such impurities released in the washing process is aniline, a substance that is classified as a category 2 carcinogen and considered toxic to aquatic life.

That is why Archroma and Jeanologia decided to team up and develop an alternative to the traditional fabric cleaning process and its subsequent water-intensive and water-polluting washings.

• The breakthrough alternative to the fabric cleaning concept presented by Jeanologia and Archroma combines the use of the aniline-free* PURE INDIGO ICON dyeing system of Archroma, and the water-free** and chemical-free “G2 Dynamic“ finishing technology of Jeanologia.
• The Archroma/Jeanologia solution allows to create aniline-free* denim, and improve the final aspect of the fabric through a fully chemical-free and almost water-free** cleaning alternative treatment.
• The Archroma/Jeanologia solution can also be used with additional Archroma coloration systems such as INDIGO REFLECTION or PURE UNDERTONES.

Umberto Devita, Business Development Manager at Archroma’s Competence Center for Denim & Casual Wear, who was the project leader for this new development, comments: “At Archroma, we strive to develop solutions in line with our principles of “The Archroma Way to a Sustainable World: Safe, efficient, enhanced, it’s our nature”. It was therefore very inspiring to work with a partner who shares the same values of developing efficient new processes to bring all know-how to our customers to maximize value – for denim that looks as good as the good it creates.”

For Jean-Pierre Inchauspe, Business Director of G2 Dynamic at Jeanologia, “this association is another step to change traditional, more polluting and water consuming processes in the textile industry for new ones using technology, improving, and boosting subsequent production stages up to the finishing of the garment, making them more efficient and allowing companies to be more competitive, increase productivity and offer a product that is completely sustainable with high quality.”

• The Green Revolution: How Microfactories Can Change the Face of Fashion by Mark Sollman, Product Manager EMEA, Mimaki Europe

With the all-important COP26 Climate Change Conference having taken centre stage in November, there is no time like the present for the fashion world to rally together in stepping up sustainability efforts and getting carbon emissions under control. Globally, the fashion industry is now estimated to account for around 10 percent of greenhouse gas emissions and 20 percent of wastewater , making the pursuit of greener production methods more pertinent than ever before. Thankfully, we are seeing a new era of production enter the fashion arena, with the increasing emergence of technologically advanced, highly automated microfactories.

Along with reducing unnecessary waste through on-demand production, microfactories have a smaller ecological footprint than traditional garment production and require no water use during the production process, making it not only a faster solution, but a greener one too.

Last year’s FESPA saw Mimaki team up with fashion designer Carolina Guzman to bring her designs to life in real time at the show, setting up its own working microfactory live on-site to take her designs from screen to garment within just a day. Guzman’s designs were created using Mimaki’s TS100-1600 Sublimation Printer, before being transferred to textile, digitally cut and finally pieced together. Devised with a string of ethical and environmental objectives threaded throughout, the microfactory also exclusively utilised eco-friendly Greentex fabric, and any remaining material was donated to Sheltersuit: a wind- and waterproof coat that can be transformed into a sleeping bag, which is provided free of charge to homeless people and refugees.

Through working with a number of strategic partners – including transfer printing expert, Klieverik; paper solutions specialist, Neenah Coldenhove; and digital cutting equipment provider, Summa – Mimaki was able to produce a collection of unique, high-quality garments live on the stand during the tradeshow, demonstrating to visitors from more than 100 countries some of the key reasons that microfactories seem set to change the future of fashion…

Unparalleled speed and versatility
Where traditionally, apparel manufacturing has centred on a production chain model of sourcing materials and producing garments in bulk, microfactories are now enabling on-demand, on-location production, making it possible to create everything from unique, one-off pieces and samples right through to entire product lines – all at unprecedented speeds. This means greater flexibility and customisation, enabling designers to modify or update designs and respond to market trends as they occur.

Simplified supply chains and minimised risk
The microfactory setup brings production in-house and on-demand, minimising the cost of not only storing stock, but also of shipping it and responsibly disposing of unsold items. Where recent geopolitical events have highlighted the fragility of global supply chains, microfactories offer a unique independence from these systems, empowering garment manufacturers to future-proof their businesses, become less reliant on external systems and suppliers, and reduce the risk of disruptions.

A boosted bottom line and a greener future
Facilitating savings in a whole line of resources, from physical storage and production space to time and energy, microfactories ultimately have the potential to significantly increase profitability for garment manufacturers, with the additional benefit of being easily scalable as production increases. Perhaps even more compelling, however, are the environmental considerations. Demonstrated on a small scale through Mimaki’s recent project, the environmental benefits inherent to microfactory production will have an even greater impact as it becomes more prolific and commonplace throughout the fashion world, with the potential to effect meaningful environmental change as adoption increases in the years to come.
