Archroma, a leader in specialty chemicals towards sustainable solutions, is teaming up with COLOURizd™, an innovator specializing in sustainable textile dyeing technologies, to set a new standard for the eco-friendlier production of sustainable textiles.

The new collaboration will enable fabric mills and brands to combine Archroma pigment coloration solutions with the COLOURizd™ QuantumCOLOUR™ yarn-coloring technology to produce high-quality, high-performance textiles with maximum consumer appeal and minimal environmental impact.

Conventional fiber-reactive methods of dyeing cellulosic and synthetic yarns are multi-step resource-intensive processes that use up to 95 liters of water per kilograms of colored yarn and discharge approximately 94 liters of effluent.

In contrast, the innovative QuantumCOLOUR™ process injects pigment and a binder directly into the yarn, using only 0.95 liters of water per kilograms of colored yarn while producing zero effluent. This represents an unprecedented reduction of 98% in water consumption alongside zero wastewater discharge, zero discharge of harmful chemicals, 73% decrease in carbon footprint and 50% reduction in energy use.*

With Archroma, textile manufacturers and apparel brands can add further value to the QuantumCOLOUR™ process with tailor-made system solutions, including JUST COLOR. This formaldehyde-free** pigment coloration system is based on Archroma’s revolutionary Printofix® pigment dispersions and Helizarin® binders to deliver exceptionally soft fabrics with high fastness and durability, while also enabling energy and chemical savings and higher productivity.

Mimaki Europe, a provider of industrial inkjet printers, cutting plotters, and 3D printers, is debuting the new Tiger600-1800TS, Mimaki’s most productive sublimation transfer printer, on its stand at ITMA 2023. This latest high-speed, compact and robust roll-to-roll inkjet printer has been designed to accelerate the analogue to digital transformation within the textile printing industry.

The Tiger600-1800TS boasts a maximum printing speed of 550 m2/h (143% faster than the previous model) owing to the renovated high-speed printhead and Mimaki’s proprietary image quality enhancement technologies. The printer’s size has also been halved compared to the previous system, with the paper mounting and winding system both located at the back of the machine. This smaller footprint enables customers to easily install multiple units to meet fluctuating demand, whilst also increasing overall production capacity.

A further environmental benefit of the Tiger600-1800TS will be the bluesign® certification of its MLSb510 series sublimation transfer inks. This certificate, expected to be awarded in June 2023, will provide assurance that these inks are of highest quality combined with due consideration for the safety of consumers and print operators, and environmental conservation, and therefore, contributing to the sustainability of the textile industry.

Mimaki’s expertise in developing reliable, easy-to-use and efficient solutions has also not faltered in the development of the Tiger600-1800TS. The printer’s ink tanks can be replaced without interrupting the printing process, minimising down time. Maintenance of the printer is also reduced with its roller paper feeding method eliminating the need for the application of adhesives onto a belt.

Following their entry into the fibres and textiles sector, as announced at K 2022, recycling machine manufacturer EREMA launches the INTAREMA® FibrePro:IV - which has been specially developed for PET fibre-to-fibre recycling - at ITMA in Milan from June 8 to 14. Thanks to its especially gentle material preparation and efficient removal of spinning oils, the rPET produced can be reused in proportions of up to 100 percent for the production of very fine fibres.

PET is regarded as a key material for the production of synthetic fibres. Around two thirds of the total volume of PET goes into the production of PET fibres for the textile industry. This highlights the importance of high-quality recycling solutions for the circular economy. By combining proven INTAREMA® technology with a new IV optimiser, EREMA succeeds in processing shredded PET fibre materials heavily contaminated by spinning oils in such a way that the finest fibres can be produced again from the recycled pellets. The system, which now joins EREMA's machine portfolio as the INTAREMA® FibrePro:IV, is characterised by a longer residence time of the PET melt. This is an essential factor for achieving high quality recycled pellets, as it allows the spinning oils and other additives used to improve the handling of the fibres during manufacturing to be removed more efficiently than in conventional PET recycling processes. Following extrusion, by polycondensation the intrinsic viscosity (IV) of the PET melt is increased in the new IV optimiser and under high vacuum to the precise level that is needed for fibre production. "Including filtration the output quality that we achieve with this recycling process is so high that ultra-fine fibres of up to 2 dtex can be produced using these rPET pellets, with an rPET content of 100 percent," says Markus Huber-Lindinger, Managing Director at EREMA. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

While the focus of the fibre and textiles application is currently still on PET fibre recycling, EREMA is committed to driving forward the recycling of mixed fibre materials from classic textile recycling collection in a next project phase. In order to accelerate development work, the EREMA Group opened its own fibre test centre, where a cross-company team is working on recycling solutions for fibre-to-fibre applications. The centre also operates a fully equipped and variable industrial-scale recycling plant. It includes the peripheral technology required and is available to customers for trials.

Mimaki Europe, a provider of industrial inkjet printers, cutting plotters, and 3D printers, has announced the introduction of two technologies at ITMA 2023: a Textile Pigment Transfer Printing System and the Neo-Chromato Process. These innovations are showcased for the first time, and ahead of commercial availability, at the exhibition in Milan, Italy, solidifying Mimaki's commitment to sustainable and environmentally friendly solutions in the textile printing industry.

Mimaki’s New Textile Pigment Transfer Printing System
The transfer printing method is more sustainable than both analogue and digital textile dye printing methods with zero water consumption and substantially lower CO₂ emissions. The system comprises three essential elements: the Textile Pigment Ink, the Transfer System and the Textile Pigment Transfer paper, Texcol®.

Texcol® is a transfer paper pioneered by Dutch paper manufacturer, Coldenhove that allows for transferring a digital print using an environmentally friendly 3-step transfer process to create a vibrant application on a wide range of materials, including natural fibres. The design is initially printed onto the paper using a customised TS330-1600 - Mimaki’s high-volume, high-quality dye sublimation printer - and Mimaki’s new pigment inks developed for the process. The module that adapts the TS330-1600 will be available as an option for existing and new Mimaki customers in Q3 2023 but is being previewed on the Mimaki stand at ITMA.

Mimaki’s new Textile Pigment Ink is undergoing bluesign certification before commercial availability. bluesign is a renowned certification programme that ensures the highest levels of safety, environmental friendliness, and sustainability within the textile and apparel industry.

As the final stage, the Texcol® paper undergoes a one-step waterless process, through an entry-level calendar machine onto the textile of choice.

Cyclical textile technology
Mimaki is also debuting its new, unique Neo-Chromato Process, which revolutionises the reuse of coloured polyester textiles.

By decolourising polyester textiles that have been dyed using dye sublimation technologies, this innovative process allows materials to be re-printed or dyed immediately, contributing to a smaller circular economy. There is no limit to how many times reused polyester can be treated with the Neo-Chromato Process and the process itself minimises water usage and pollution by enabling the disposal of the absorbent paper and decolouring solvents used in the process as burnable waste.

On June 9, Hohenstein celebrates World Accreditation Day (WAD2023) along with 30 years as an accredited testing laboratory. In 1993, Hohenstein’s first lab received official certification to test textile products competently, reliably and impartially according to internationally recognized standards. With the expansion of its testing business, the company, headquartered in Boennigheim, Germany, has since gained numerous other accreditations for its global laboratories.

"The accreditations give our customers confidence that we comply with the required quality control procedures," says Julia Seeberg, who as Head of Quality Management also oversees the regular monitoring of the laboratories by DAkkS, the Deutsche Akkreditierungsstelle. “Everything possible is done to ensure the integrity of the test results.” In addition to DAkks accreditations of the testing laboratories for textile technological, biological, chemical and physical tests, Hohenstein is accredited as a certification and inspection body. Hohenstein's 75 years of expertise in the testing business complement its accreditation and provide an important basis for its long-standing customer trust.

Hohenstein laboratories in China, Bangladesh, Hong Kong and India have accreditations from the respective national and international accreditation bodies. The labs celebrate World Accreditation Day by highlighting the importance of accredited laboratories for the product quality and sustainability. "The demands of suppliers and consumers have increased," Julia Seeberg also notes. “For manufacturers to remain credible, it is even more imperative to demonstrate compliance with defined and standardized quality criteria.”

The globally valid quality standard for testing and calibration laboratories is DIN EN ISO/IEC 17025. The standard specifies general requirements for the competence, impartiality and uniform working methods of laboratories that operate internationally. Accreditations in accordance with DIN EN ISO/IEC 17020 and 17065 exist for the inspection and certification bodies. In addition, Hohenstein is an accredited testing laboratory for medical devices, where biological, chemical and physical laboratory tests are carried out. These tests form the basis for conformity with the European Medical Device Regulation (MDR).

Vliesstoffe spielen in verschiednen Branchen eine zentrale Rolle, so in der Automobilindustrie, dem Gesundheitswesen, der Medizin, dem Bauwesen oder der Filtration. Da die Nachfrage nach diesen Materialien weiter steigt, schließen sich Bettarini & Serafini S.r.l bematic, Siriotek und das Fraunhofer-Institut für Techno- und Wirtschaftsmathematik ITWM zusammen, um die Air-Lay-Technologie weiterzuentwickeln. Auf der ITMA, der Fachmesse für Textilien, Bekleidung und Innovation, stellen die drei Partner erstmals gemeinsam das Projekt vor.

Seit fast 50 Jahren ist die italienische Firma bematic in der Vliesstoffproduktion tätig. Die Entwicklung von fortschrittlicher Air-Lay-Produktionsprozesse steht bei dem Unternehmen im Fokus sowie die Konstruktion, Herstellung und Prüfung von Hochleistungskardieranlagen für Vliesstoffe. Die Ingenieure des Schweizer Unternehmens Siriotek konzentrieren sich auf Simulationen und Tests, die die praktische Problemlösung unterstützen. Das Fraunhofer ITWM bringt sowohl Wissen als auch Erfahrung in der Textiltechnik und der Prozessoptimierung ein und steuert Know-how in der mathematischen Modellierung sowie Charakterisierung von Air-Lay-Prozessen für Stapelfasern bei.

Die drei Partner wollen gemeinsam die nächste Generation von Krempelmaschinen entwickeln, die Leistung und Qualität bei der Air-Lay-Verarbeitung mit Stapelfasern gewährleisten und gleichzeitig Energieverbrauch, Abfallerzeugung und Kohlenstoffemissionen reduzieren. Die Zusammenarbeit bündelt das Fachwissen und die Innovationskraft der Dreien in ihren jeweiligen Bereichen.
 
Schneller, dichter, effizienter
Air-Lay-Technologien sorgen für die thermische, mechanische und chemische Vliesverfestigung. Hierbei wird das Rohmaterial geöffnet und mit einer Walze in einen Luftstrom eingebracht. Dieses Luft-Faser-Gemisch landet auf einem Band und wird dort durch Absaugung verdichtet. »Durch einen gemeinschaftlichen Ansatz erweitern wir die Grenzen der Air-Lay-Technologie, um höhere Produktionsgeschwindigkeiten, eine bessere Gleichmäßigkeit des Vlieses und eine bessere Faserausnutzung zu erreichen sowie letztendlich Lösungen zu liefern, die vollständig auf die individuellen Produktionsanforderungen zugeschnitten sind«, erklärt Giovanni Di Lorenzo, Gründer und Chefingenieur von Siriotek.
 
Zusätzlich minimiert das Projekt so den ökologischen Fußabdruck, ohne dabei die Leistung zu beeinträchtigen. »Wir treiben den Fortschritt voran, verbessern die Produktionsqualität und tragen zu einem nachhaltigeren sowie effizienteren Ökosystem in der Textilindustrie bei«, ergänzt Dietmar Hietel, Leiter der Abteilung »Transportprozesse« am Fraunhofer ITWM. Auch Giovanni Bettarini, Partner und kaufmännischer Leiter bei bematic, ist vom Projekt überzeugt: »Durch diese Zusammenarbeit werden wir in der Lage sein, unseren Kunden Fertigungslösungen für verschiedene Anwendungen in den Bereichen Automobil, Bau, Filtration und Geotextilien anzubieten.«

Carbios will receive grants totaling €54 million from French State via France 2030 and Grand-Est Region to finance construction of world’s first PET biorecycling plant and accelerate R&D activities

Carbios announces that its project has been selected by the French State for funding of €30 million from the French State as part of the investment plan France 2030, and €12.5 million from the Grand-Est Region.  The implementation of this funding is conditional to the European Commission’s approval of the corresponding state aid scheme, followed by the conclusion of national aid agreements. As part of the national call for projects on “Plastics Recycling” operated by ADEME^[1], Carbios’ project to finalize the industrialization of its unique PET biorecycling process has been selected. The reference plant in Longlaville in the Grand-Est region will be the world’s first PET biorecycling plant and is due for commissioning in 2025. This plant will make it possible to relocate to France the production of the two basic components of PET, PTA and MEG^[2], both derived from the Carbios process.

Carbios also announces that it has been granted total funding of €11.4 million from the French State as part of France 2030, of which €8.2 million directly for Carbios (€5 million in repayable advances) and €3.2 million for its academic partners INRAE^[3], INSA^[4] and CNRS^[5] via the TWB^[6] and TBI^[7] joint service and research units. This funding will enable to continue its research into the optimization and continuous improvement of Carbios’ enzymatic technologies.

The plant will secure the sales of the first volumes of recycled PET produced with Carbios’ technology, and to offer its partners recycled PET of the same quality as virgin PET. Once the necessary permits have been obtained, which should be granted by the end of 2023, in line with the announced start of construction before the end of the year, the plant is scheduled to be commissioned in 2025. This will be followed by a period of ramp-up to full capacity. The plant will have a nominal processing capacity of 50,000 tonnes of PET waste per year, equivalent to 2 billion bottles or 2.5 billion food trays.

Selection for funding by the French State through France 2030 and the Grand-Est Region complements the recent announcement of an exclusive, long-term partnership with Novozymes^[8], a leader in enzyme production, one of the main aims is to ensure the supply of enzymes to Carbios’ Longlaville plant and future licensed plants. In addition, Carbios recently secured a first supply source for its future plant by winning part of the CITEO tender for the biorecycling of multilayer trays^[9].

KARL MAYER GROUP will be presenting a WEFTTRONIC® II G at the ITMA with new features and upgrades for greater efficiency. This warp knitting machine with weft insertion produces lattice structures from high-strength polyester, which are firmly established in the construction industry in particular. With a working width of 213", it offers productivity and further advantages through design innovations. New features include weft thread tension monitoring, management and the new VARIO WEFT laying system. The component for the weft insertion aims at maximum flexibility. It allows the patterning of the weft yarn to be changed quickly and easily electronically, without mechanical intervention during yarn insertion and without limits on repeat lengths. In addition, there is less waste.

The KARL MAYER GROUP also supports its customers with well thought-out Care Solutions. The new support offers include retrofit packages for retrofitting control and drive technology for weft insertion and composite machines, and service packages that bundle various services. These include machine inspections and the replacement of all drive belts. The customer benefits from fixed prices that cover the costs of technician assignments, various discount options and transparent services.

A new solution for the vertical greening of cities is presented from the field of application for technical textiles. The core of the innovation is a grid textile produced on warp knitting machines with weft insertion by KARL MAYER Technische Textilien GmbH. The knitted lattice fabric is made of flax. It is used as a climbing aid for fast-growing plants, and after the greening phase, in autumn, it can be recycled together with these plants as biomass in pyrolysis plants to produce electricity and activated carbon. In summer, the planted sails lower the ambient temperature through evaporation effects. In addition, photosynthesis creates fresh air and binds CO2. Other important advantages are low soil requirements and flexible placement in public spaces. The greening system was developed by the company Micro Climate Cultivation, OMC°C, with the support of KARL MAYER Technische Textilien.

The KARL MAYER GROUP will also be exhibiting a sustainable composite solution made from natural fibres. The reinforcing textile of the innovative lightweight material is a multiaxial non-crimp fabric, which was also produced from the bio-based raw material flax on a COP MAX 4 from KARL MAYER Technische Textilien. The boatbuilding specialist GREENBOATS uses natural fibre composites to achieve sustainable products. The fact that it succeeds in this is shown, for example, by the Global Warming Potential (GWP): 0.48 kg of CO2 per kilogram of flax reinforcement compares with 2.9 kg of CO2 per kilogram of glass textile.
