From the Sector

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.

Am 1. Januar 2023 ist das Lieferketten-Sorgfaltspflichtengesetz (LkSG) in Kraft getreten. Die Unternehmen werden damit verpflichtet, Menschenrechte und Umweltbelange entlang ihrer globalen Lieferkette zu wahren. Der Bundesverband Medizintechnologie (BVMed) unterstützt die Medizintechnik-Branche bei der praktischen Umsetzung der neuen LkSG-Pflichten mit einer kostenlosen Handreichung. Die Orientierungshilfe besteht aus insgesamt sechs Modulen, von denen nun auch Modul 3 „Ausgestaltung des Beschwerdemechanismus“ und Modul 5 „Jährliche Berichterstattung“ online gegangen sind. Zuvor waren bereits Module zum Anwendungsbereich, zur Compliance-Dokumentation und zur Ausgestaltung der Governance vom BVMed veröffentlicht worden. Die Module können unter www.bvmed.de/lksg heruntergeladen werden.

Das Gesetz gilt für alle Unternehmen, die in Deutschland mehr als 3.000 Mitarbeitende beschäftigen. Ab dem 1. Januar 2024 gilt es ab 1.000 Beschäftigte. Auch kleine und mittelständische Medizinprodukte-Hersteller und -Zulieferer können mittelbar betroffen sein. Dabei gilt das LkSG für sämtliche Wirtschaftsbereiche, also auch für das Gesundheitswesen einschließlich des Medizintechnik-Sektors.

„Unser Ziel ist es, mit den Publikationen zu einem einheitlichen Branchenstandard für die Implementierung des LkSG in Medizinprodukte-Unternehmen beizutragen. Damit erreichen wir Harmonisierung, Rechtssicherheit und Effizienz. Moderne Medizintechnologien dienen den Menschen und ihrer Gesundheitsversorgung. Hierbei müssen die Lebensgrundlagen der Menschen im Blick behalten werden. Menschenrechte müssen umfassend geachtet und sichergestellt werden. Dies muss ein zentrales Anliegen in einer globalisierten Welt mit komplexen Liefer- und Warenströmen sein“, kommentiert BVMed-Geschäftsführer und Vorstandsmitglied Dr. Marc-Pierre Möll. Die Module wurden vom BVMed gemeinsam mit der Kanzlei Clifford Chance und der Produktkanzlei entwickelt.

Beschwerdemechanismus und jährliche Berichtserstattung
Die neu veröffentlichten Module 3 und 5 beleuchten die Ausgestaltung des Beschwerdemechanismus und die jährliche Berichtserstattung.

• Nach § 8 LkSG sind die Unternehmen verpflichtet, ein angemessenes und unternehmensinternes Beschwerdeverfahren einzurichten, welches es Personen ermöglicht, auf menschenrechtliche und umweltbezogene Risiken sowie auf Verletzungen menschenrechts- und umweltbezogener Pflichten hinzuweisen. Das dritte Modul enthält Vorschläge für die Ausgestaltung des Beschwerdemechanismus.
• Das fünfte Modul gibt eine Übersicht über die Mindestangaben, welche die Unternehmen im Rahmen ihrer jährlichen öffentlichen Berichterstattung nach § 10 Abs. 2 LkSG sowohl gegenüber der zuständigen Behörde, d. h. dem Bundesamt für Wirtschaft und Ausfuhrkontrolle („BAFA“), als auch gegenüber der Öffentlichkeit offenlegen müssen.
• Modul 4 zur Risikoanalyse, -priorisierung, -prävention und -abhilfe folgt bis Ende Januar 2023.

„Das LkSG begründet umfangreiche Sorgfaltspflichten zum Schutz von menschenrechtlichen und umweltbezogenen Belangen entlang der gesamtem Lieferkette“, erläutern BVMed-Nachhaltigkeitsexpertin Clara Allonge sowie BVMed-Rechtsexpertin Dr. Katja Marx.

Belgian textile innovator Devan Chemicals will launch Purissimo® NTL, a biobased and readily biodegradable allergen control technology, at the upcoming Heimtextil trade show in Frankfurt (January 10-13, 2023). It is based on probiotic encapsulation technology and can be applied to textiles during the finishing stage of the textile manufacturing process. Purissimo® NTL cleans up pet dander, pollen and house dust mite allergens in textiles throughout the home.

Purissimo® NTL is based on Devan’s already well-established probiotics, incorporated into a new microcapsule shell. The shell is based on a natural crosslinked biobased polymer, which results in microcapsules that are up to 97% biobased and readily biodegradable (OECD 301B).

Firstly, dormant probiotic bacteria (spores) are encapsulated. The microcapsule product is then integrated into textiles. Friction opens the capsules and releases the spores. The spores absorb humidity, self-activate and start to multiply. The probiotic bacteria start to consume the allergens that cause allergic reactions and asthma. Due to lower allergen concentration, individuals with respiratory allergies such as house dust mite matter, pet allergens and pollen allergens will have milder to no symptoms and hence a better well-being feeling.

Purissimo® NTL can be used on a wide range of textiles such as mattresses, pillows, bedcovers, blankets but also upholstered furniture, carpets, curtains and public transportation and pet items, such as bedding. It is Oeko-tex® compliant, has a long-lasting effect and a wash durability up to 30 washes is achievable.

California born and bred, Tillys is one of fashion’s leading specialty casualwear retailers. And now, thanks to its collaboration with Recover™ , their premium denim brand RSQ, it is set to become a leader of sustainable fashion.

The three brands – Tillys, Recover™ and RSQ – have come together to create a sustainable capsule collection. The new collection includes classic-inspired denim, a tee, and an on-trend chore jacket, all of which contain a minimum of 20% of Recover’s low-impact recycled cotton fiber. To shop the exclusive Recover™ pieces in the RSQ collection, go to tillys.com or visit one of Tillys stores across 33 states.

To bring this collaboration to life, textile waste has been salvaged that would otherwise end up in a landfill to create high-quality recycled fiber that Tillys used to produce its premium-quality RSQ collection. Using recycled fiber significantly reduces the carbon and water footprint compared to apparel made with virgin fiber. This collaboration models how post-industrial textile waste can be integrated back into the system creating a more sustainable production model.

“We are delighted to celebrate this new partnership with Tillys, helping to reduce the environmental impacts created by the fashion industry and pave the way towards a more sustainable future.”
– Alfredo Ferre, CEO Recover™

BTMA member Dent Instrumentation – a specialist in contactless yarn sensors – has become an employee-owned business following the formation of a new Employee Ownership Trust (EOT).

The company, based in Colne, Lancashire, has been family owned since its founder Geoffrey Dent secured a patent for the very first contactless yarn sensor in the 1960s. It has been successfully run by his son Andrew and the family for many years.
“This deal ensures a smooth succession as well as the preservation of the company’s core family values and the Dent Instrumentation name,” said Managing Director Colin Hull. “The EOT structure will maintain the integrity of the business for years to come.”

The liability of Dent sensors makes them integral to the yarn spinning and winding processes and they have become a standard throughout the textile industry, recognised for their quality, performance and value. They are used by major manufacturers of textiles and textile machinery under either Dent or OEM machine builder brands.

• Neue Materialkategorien in der Datenbank des VDI ZRE zu Verwendungsmöglichkeiten von Wertstoffen

Es muss nicht immer aus erster Hand sein: Die Verwendung von Sekundärrohstoffen bzw. der Verkauf von nicht mehr benötigten Wertstoffen kann zu einer verbesserten Wettbewerbssituation beitragen, indem Kosten reduziert und zusätzliche Einnahmen generiert werden. In der Online-Materialdatenbank des VDI ZRE können Unternehmen nun in insgesamt sechs Kategorien gezielt nach Alternativen für Primärrohstoffe suchen.

Für Textilien, Kunststoff, Baustoffe, Metalle, Glas und Papier werden Sekundärrohstoffe mit möglichen Bezugsquellen aufgeführt. Zu jedem Eintrag gibt es eine kurze Beschreibung sowie Angaben zur Geometrie und den Einsatzmöglichkeiten des Wertstoffs. Im Bereich „Beispiele aus der Praxis“ wird aufgezeigt, wie andere Unternehmen bereits erfolgreich Nebenprodukte und Sekundärrohstoffe einsetzen.

Die Materialdatenbank zu Nebenprodukten und Sekundärrohstoffen unterstützt insbesondere Unternehmen, die bisher wenig Erfahrung mit dem Einsatz von Sekundärrohstoffen als Alternative zu Primärrohstoffen oder mit der Verwertung bzw. Veräußerung von in der Produktion anfallenden Wertstoffen haben. Denn hier besteht großes Potenzial für Kosteneinsparungen und die Betriebe beweisen mit diesem Handeln ökologische Verantwortung.

Die vom Bundesumweltministerium beauftragte Datenbank wird auch weiterhin in regelmäßigen Abständen aktualisiert. Die Datenbank ist abrufbar unter https://www.ressource-deutschland.de/werkzeuge/ressourceneffizienz-in-der-praxis/materialdatenbank/.
