From the Sector

Within its TEXTILE SOLUTIONS, the CHT Group has developed solution approaches for manufacturing companies in the textile value chain that have to use a lot of energy for their production. This is intended to compensate high energy costs and make a positive contribution to climate protection.Application specialists work with customers to develop individual savings potentials that are specifically tailored to the production facilities and requirements. Thus, depending on the process, fabric and machine, energy savings of up to 30% can be achieved with the use of innovative CHT textile auxiliaries, dyes/pigments and the corresponding process optimisations. In addition, the numerous concepts and optimally matched products can minimise water consumption or shorten the process time.

Energy-efficient cold bleaching instead of pad-steam bleaching processes in continuous pretreatment and the 4SUCCESS process for energy-efficient and resource-saving pretreatment and dyeing of cotton help to save energy. Likewise, the use of polymer binders, which do not require energy-intensive fixation, saves energy.

Efficient pretreatment with the new polymer technology CPT (Comb Polymer Technology) achieves good cleaning effects even with low liquor ratios and thus less water to heat up. To save costs for energy-consuming heating, there is also the gentle low-temperature fixation in the easy care finishing. The OrganIQ EMS Jeans system enables jeans finishing with a reduced application temperature compared to standard processes.

With TIME BOOST, a process for fast polyester dyeing processes, not only significant energy but also time savings are achieved by omitting pre-washing and by shortening heating and migration times. SHORT CUT also leads to shorter process times when dyeing polyamide.

To avoid cost-intensive intermediate drying, the CHT Group offers the SCREEN-2-SCREEN with PRINTPERFEKT S2S which facilitates printing in a wet-on-wet technology.

In addition to numerous other products, the CHT Group also offers its customers digital tools to optimally support process optimizations. The "BEZAKTIV Soaping Advisor" calculation program within the CHT Textile Dyes app can be used to evaluate and improve dyeing and soaping processes in a simple and target-oriented way.

Over the past three years, a dedicated AI development team at BTMA member Shelton Vision has been developing tailored machine learning solutions for the textiles industry.

The aim has been to elevate the detection process and the accuracy of naming and grading subtle defects in textiles, in real time within production environments.

“Big Data ‘off-the-shelf’ systems such as those behind technolgies like facial recognition and Google Maps involve reading many thousands of single images each second and simply take too long to accumulate sufficient data for what’s required in this specific case,” says Shelton Vision CEO and Managing Director Mark Shelton. “A feature of the textile industry is that in many sectors, the product range changes several times within a year and it is not uncommon to have to inspect hundreds, if not thousands of different styles in a year based on precise settings.”

In terms of defect types, he adds, there may typically be over 100 that need to be accurately detected, classified (named) and graded in real time.

“Added to this is the need to ‘filter out’ the random occurrence of ‘non defects’, such as loose threads, lint and dust on the surface – the number of which can be higher than actual defects – and it is clear that a bespoke system is required.”
The development team has consequently established metadata for identifying defect properties, enabling the successful identification of faults from a much smaller number of images.

“The system employs a unique combination of machine learning for automated style training and novel algorithms for defect detection, to provide high quality images for the AI real time defect classification and grading software,” Shelton explains. “Due to the inherent variation in fabric features – raw materials, construction, texture, colour and finishes, as well as the differing product quality standards in value chains and the regional variations in what defects are called – our AI engine uses models built for each individual company or group of companies, or product value chain.”

The AI models are constructed so that the user operatives can populate them with their own data produced by the vision system or by obtaining defect images from another imaging source (eg a mobile phone camera).  

The occurrence of defects is sporadic and many defect types occur infrequently, although when they do, they can have severe consequences. These scenarios re-enforce the need for the AI engine to be quickly set up and able to operate accurately with limited data sets of typically between 30 and 50 good quality images per defect type.

A further feature is a tool enabling the user to periodically ‘clean up’ the AI data during the set up phase. This is used to resolve conflicting data and to correct mis-named images.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

Generally, the highest cost component of fabric production is the raw material and in addition to finished product inspection, a cost effective use for vision systems is in process operation.

“There is a need for the real time detection of defects that are being created in separate processes, such as printing or coating and for real time automated systems that can accurately determine the defects and their severity and provide a reliable signal for an operative to rectify the issue, This can result in considerable savings.

Prior to Shelton introducing powerful customised machine vision and real time defect classification, the only systems available were those that required manual sifting through vast numbers of images, which included both real defects and ‘non defect’ images. The task was very often overwhelming and did not provide much benefit beyond manual fabric inspection.

Many people across the world are bedridden – be it due to illness, an accident or old age. Because those affected often cannot move or turn over by themselves, they often end up with very painful bedsores. In the future, it should be possible to avoid bedsores with the help of materials that can be programmed to entirely adapt their form and mechanical properties. For example, the body support of mattresses made from programmable materials can be adjusted in any given area at the push of a button. Furthermore, the support layer is formed in such a way that strong pressure on one point can be distributed across a wider area. Areas of the bed where pressure is placed are automatically made softer and more elastic. Caregivers can also adjust the ergonomic lying position to best fit their patient.

Materials and microstructuring
Materials for applications requiring specific changes to stiffness or shape are being developed by researchers from Fraunhofer CPM, which is formed of six core institutes with the aim of designing and producing programmable materials. So, how can we program materials? “Essentially, there are two key areas where adjustments can be made: the base material – thermoplastic polymers in the case of mattresses and metallic alloys for other applications, including shape memory alloys – and, more specifically, the microstructure,” explains Dr. Heiko Andrä, spokesperson on the topic at the Fraunhofer Institute for Industrial Mathematics ITWM, one of the Fraunhofer CPM core institutes. “The microstructure of these metamaterials is made up of unit cells that consist of structural elements such as small beams and thin shells.” While the size of each unit cell and its structural elements in conventional cellular materials, like foams, vary randomly, the cells in the programmable materials are also variable – but can be precisely defined, i.e., programmed. This programming can be made, for example, in such a way that pressure on a particular position will result in specific changes at other regions of the mattress, i.e., increase the size of the contact surface and provide optimal support to certain areas of the body.

Materials can also react to temperature or humidity
The change in shape that the material should exhibit and the stimuli to which it reacts - mechanical stress, heat, moisture or even an electric or magnetic field - can be determined by the choice of material and its microstructure.

The journey to application
A single piece of material can take the place of entire systems of sensors, regulators and actuators. The goal of Fraunhofer CPM is to reduce the complexity of systems by integrating their functionalities into the material and reducing material diversity. We always have industrial products in mind when developing the programmable materials. As such, we take mass production processes and material fatigue into account, among other things,” says Franziska Wenz, deputy spokesperson on the topic at the Fraunhofer Institute for Mechanics of Materials IWM, another core institute of Fraunhofer CPM. The initial pilot projects with industry partners are also already underway. The research team expects that initially, programmable materials will act as replacements for components in existing systems or be used in special applications such as medical mattresses, comfortable chairs, variable damping shoe soles and protective clothing. “Gradually, the proportion of programmable materials used will increase,” says Andrä. Ultimately, they can be used everywhere – from medicine and sporting goods to soft robotics and even space research.

Der Bundesverband Medizintechnologie (BVMed) trauert um seinen langjährigen Geschäftsführer und Vorstandsmitglied Joachim M. Schmitt. Er verstarb am Neujahrstag 2023 im Alter von 71 Jahren.

Schmitt kam 1985 zum BVMed und war von 1990 bis 2019 Geschäftsführer des deutschen Medizintechnik-Verbandes. Unter Führung von Schmitt wurde der Vertretungsbereich des Verbandes kontinuierlich ausgebaut, eine proaktive politische Arbeit etabliert und mit dem Umzug nach Berlin 2001 konsequent intensiviert. Weitere Meilensteine waren die Erarbeitung des Kodex Medizinprodukte in den 90er Jahren und der Aufbau der BVMed-Eventtochter MedInform (heute BVMed-Akademie) zu einem stetig wachsenden Informations- und Seminar-Service.

„Wir verlieren mit Joachim M. Schmitt eine prägende Gestalt des Verbandes und das jahrzehntelange Gesicht der deutschen MedTech-Branche. Wir verneigen uns vor einer großen Persönlichkeit und seiner unternehmerischen Leistung. Sein Wirken und sein menschliches Vorbild werden unvergessen bleiben“, so der BVMed-Vorstandsvorsitzende Dr. Meinrad Lugan sowie BVMed-Geschäftsführer und Schmitt-Nachfolger Dr. Marc-Pierre Möll.

Haelixa, the Swiss traceability company and Damteks Textiles have announced a collaboration to mark and trace recycled acrylic fiber. Damteks is offering their recycled yarn to customers whereby they are able to place an order with the unique Haelixa DNA already attached.

The Haelixa solution is DNA markers which are solved in liquid and applied to fibers as a fine spray. Spot checks are completed after spraying to determine the presence of DNA and identify the product. The test is based on PCR technology that is 100% reliable and has forensic validity.

Damteks saw an increase in demand for blended yarn in the last year. The request is most often a composition of 30% recycled fiber with 70% standard fiber. Brands are looking for options to be more sustainable and Damteks proactively sought out an answer. They are offering the yarn with Haelixa DNA to validate the recycled acrylic in the mix.

The haelixa team visited the Damteks recycling facility in Istanbul to kick off the partnership that will continue throughout 2023. The traceability program has the DNA sprayed on the recycled fibers before spinning. The project also saw the use of a tailored Haelixa liquid sprayer designed by the team based in Switzerland. When manufacturers do not have built-in moisturizing systems, Haelixa provides them with a custom unit to shower the DNA liquid onto the fibers. This sprayer is engineered to match the mechanical processing of the customer.

Damteks is a family-owned business that pride itself in carefully selecting environmentally responsible options for its production processes. On top of the certifications they have obtained including - GRS, RCS, GOTS, OCS - Damteks decided to have their products "Marked and Traced by Haelixa" to add additional credibility and reliability. Damteks plans to offer marked and traced by Haelixa yarn in different dyes as their offering to brands.

In occasion of the next edition of Pitti Uomo, Bemberg™ by Asahi Kasei – the unique fiber with a circular economy footprint obtained from cotton linters through a closed-loop process ensuring certified sustainability credentials through its transparent and traceable approach- reveals a very special Bemberg™ fabrics smart range dedicated to premium denimwear.

This has been made possible thanks to the partnership with PureDenim, a leading Italian company whose strategy since 10 years is based on an entire re-design of the production system, inspired by circular economy principles that combines technology and innovative materials in order to offer the highest levels of design, innovation and real responsible values derived from an holistic approach to sustainability.
The “Blue di Cupro” collection is made with seven fabrics made with Bemberg™, either 100% Bemberg™ or in blend with cotton, wool, and it applies the most advanced Pure Denim Technologies. The Blue di cupro fabrics made with Bemberg™ will also be dyed with “Smart Indigo” an indigo dye technology internally produced by PureDenim, through a chemical-free production. The only elements involved are: water, indigo pigments, and electricity. In terms of finishing, fabrics’ looks and performances are enhanced by the “Eco Sonic” ultrasounds finishing technology which brings significant reduction of water used, increased aesthetic features and controlled discoloration. And last but not least every yarn used at PureDenim is protected by NaturalReco® a 100% natural product that completely SUBSTITUTE the use of plastic films that are one of the key causes of microplastic emission for denim application.

“Blue” seems to be the new colour of Bemberg™, in fact, the company in early November 2022 announced, at the Blue Friday initiative by UNESCO's Intergovernmental Oceanographic Commission (IOC), the achievement of the OK biodegradable MARINE certification, which guarantees the biodegradability of its products even in the marine environment, as certified by TÜV AUSTRIA, meaning a lot in the context of microplastics in water issue solutions. This Bemberg™ certification’s achievement comes on top of other key ones such as the INNOVHUB report that confirms Bemberg™ biodegradability in soil without releasing hazardous substances, the RCS by Textile Exchange, and the Oeko-Tex Standard 100 and ISO 14001 corporate certifications.

2020 und 2021 lief es auch Corona bedingt richtig gut für die Outdoor-Branche. Selbst die Nachfrageberuhigung im laufenden Jahr, die nach aktueller Einschätzung des Forschungsinstituts Marketmedia24 zu einem Minus von 1,2 Prozent führen könnte, stehen nicht für einen Absturz. Denn die Umsätze liegen dann immer noch um 11,4 Prozent über denen des Vor-Corona-Jahres 2019. Nicht allein diese Tatsache lässt aufhorchen: In den ersten zehn Monaten dieses Jahres stieg der Umsatz mit nachhaltigen Outdoor-Textilien und -Schuhen gegenüber Vorjahr allein auf den Portalen der Platform Group, Wiesbaden, um 24,4 Prozent. Während gleichzeitig die durchschnittlichen Ausgaben für Outdoor-Textilien und -Schuhe mit einem Rückgang von 2,1 Prozent in 2022 das sich abschwächende Kaufverhalten spiegeln. Die generelle Kaufzurückhaltung der Deutschen bekommen derzeit alle Outdoor-Händler zu spüren. Selbst der Online-Handel wird das laufende Jahr mit einem leichten Minus bilanzieren, so die aktuelle Vorausschau der Kölner Marktforscher.

Sport unter freiem Himmel wie Trekking, Joggen, Walken und Biken erlebte in den beiden Corona-Jahren 2020 und 2021 großen Zulauf – insbesondere als Freizeit- und Reiseersatz für alles das, was die Pandemie unmöglich machte. Und man deckte sich passend mit Outdoor-Bekleidung, -Schuhen und Ausrüstungen ein und legte dabei immer mehr Wert auf nachhaltige Ware. Ein Trend, der die Industrie zunehmend veranlasst, den Anteil an recycelten Materialien auszubauen.
Carina Dietrich, verantwortlich bei Sympatex für Brand Communication Strategy und Business Development: „Besonders im Textilbereich sehen wir über alle Sportarten ein starkes und immer weiter steigendes Interesse hinsichtlich eines nachhaltigen Konsumverhaltens und das Erreichen einer Kreislaufwirtschaft.“
Gleichzeitig sorgen allerdings die unterschiedlichsten Informationen, der Label Dschungel sowie das tatsächlich existierende Greenwashing für Unsicherheit im Markt. Zudem tragen die aktuellen Krisen zur Verunsicherung der Kunden bei. Jürgen Hanke, Vertriebsleiter bei der Platform-Group, prognostiziert, dass sich unter dem Eindruck steigender Energiepreise erst zeigen muss, welchen Wert Kunden und Kundeninnen auf nachhaltige Produkte legen oder ob sie doch wieder mehr preisbewusstere Alternativen kaufen. Zumindest im Oktober 2022 sank der Umsatz mit nachhaltigen Outdoor-Textilien und -Schuhen auf den Portalen der Platform Group um 50 Prozent, während hier Outdoor insgesamt gleichzeitig „nur“ um 27,4 Prozent nachgab. Allerdings weist der Umsatztrend in den Monaten Januar, Juni und September klar daraufhin, dass Nachhaltigkeit ein Nachfragefaktor bleibt.

Auch weil die Preisfrage überholt ist (zumal es jetzt auch immer mehr Secondhand-Angebote im Handel gibt), ist Stefan Brunner, Director Sports beim iscm-institute und Experte im Sport-Team von Marketmedia24, überzeugt. Seiner Meinung nach kann es sich kein Stakeholder der Branche – sei es Industrie oder Handel – erlauben, die Nachhaltigkeit zu ignorieren. Vielmehr ist „die Sportartikelbranche gut beraten, ihre Führungsposition rund um dieses Thema auszubauen und damit auf den Trend nach mehr qualitativem Konsum einzuzahlen.“ Denn Nachhaltigkeit wird zweifelsohne zum neuen Statussymbol als Ausdruck einer Haltung. Schützenhilfe kommt da auch von der Anfang 2022 vorgestellten nachhaltigen Textilstrategie der Europäischen Kommission. Danach wird der Textilsektor die erste Branche sein, die vollständig zu einer Kreislaufwirtschaft übergeht: Bis 2030 sollen Textilprodukte, die in der EU in Verkehr gebracht werden, langlebiger, wiederverwendbarer, reparierbarer, recycelbar und energieeffizienter sein.

In view of the easing of pandemic restriction policies in China, the Spring Editions of Intertextile Shanghai Apparel Fabrics, Yarn Expo and Intertextile Shanghai Home Textiles have been moved to the new timeslot of 28 – 30 March 2023. This will allow both local and international fairgoers more time to prepare for their participation, with a higher industry turnout now expected at the three fairs. The fairs will still be located at the National Exhibition and Convention Center in Shanghai where they were originally due to be held from 8 – 10 March.

Discussing the change of dates, Ms Wilmet Shea, Deputy General Manager of Messe Frankfurt (HK) Ltd explained: “After talking to our stakeholders, we believe adjusting the spring show dates to the end of March is the right move. It provides enough time for exhibitors and visitors from local and abroad to plan for the fairs and capitalise on the ample international business opportunities brought by the reopening of China’s border.”

Under the motto “People Matter” A+A 2023, a Trade Fair for Safety, Security and Health at Work, will revolve around the most important trends of our time: sustainability and digitalisation. Here, exoskeletons also play a prominent role as tomorrow’s ergonomic tools. An important conference in this field is WearRAcon Europe which will be held at A+A from 25 – 26 October 2023 for the first time.

The Conference will be organised by the Fraunhofer Institute IPA in cooperation with the Stuttgart University and the Wearable Robotics Association (WearRA). The 38th A+A Congress, which is held by Bundesarbeitsgemeinschaft für Sicherheit und Gesundheit bei der Arbeit (German Federal Association for Occupational Safety and Health - Basi) will be closely dovetailed thematically and in terms of content with it.

Being able to walk again despite a serious injury, handle heavy parts without outside help or simply do overhead work comfortably and for extended periods of time - the advantages of exoskeletons have already convinced numerous industries. Exoskeletons and wearables are now already being used successfully in industry and commerce, and major machine builders and automakers as well as the medical sector are continuing to experiment with man-machine connections. Currently, the global market volume for exoskeletons is valued by leading analysts at over US$20 billion by 2030.¹

The WearRAcon Europe Conference 2023 will provide new insights into the promising world of exoskeleton systems from different perspectives and, in conjunction with the A+A Congress, set future-oriented impulses. Lectures by renowned exoskeleton pioneers combined with testimonials presented by users from a variety of industries and keynotes by experts will round off the programme. And, like at the previous A+A, a Self-Experience Space will again be set up so that the exoskeleton systems of various manufacturers can be tested in realistic work scenarios.

In parallel with the Self-Experience Space, the large live study Exoworkathlon will also take place again. Trainees from various mechatronic training courses have to complete a concourse and perform holding, lifting and assembling tasks, which have been specially developed with the industry. Data is prospectively collected with different measuring sensors to measure the effects of exoskeletons. In the Exoworkathlon, the IPA focuses especially on prevention for young employees in order to raise awareness of the issue and counteract ailments at an early stage.
