From the Sector

Art meets sustainable fashion in the third edition of the project "CirculART", the initiative that sees companies, artists and fashion designers working together with Cittadellarte - Fondazione Pistoletto, showing how new balanced forms of production, design and sharing can be explored through a careful choice of materials and of sustainable supply chains. Three key concepts underpin the circularity of sustainable fashion and therefore this project: Reduce - reducing the consumption of raw materials, Reuse - reuse of raw materials, Recycling - regeneration.

The project CirculART is conceived and developed in collaboration between Fashion B.E.S.T. and UNIDEE Residency Programs, and led by the Foundation's team of curators.

Fashion B.E.S.T. - Better Ethical Sustainable Think-Tank, Cittadellarte - Fondazione Pistoletto’ sustainable fashion office, was created by artist Michelangelo Pistoletto and Franca Sozzani. Since 2009, B.E.S.T. has been working on the development of sustainability in the textile sector, to lead to a contamination between art, which assumes social responsibility, and the world of fashion, which is looking to define a new ethical and sustainable model.

CirculART proposes a new link between fashion and art, engaging both in a conscious and innovative combination of sustainability, sensitivity, beauty and union. The project links territory and production factories, bringing together actors from the different sectors making up the textile supply chain that work on the basis of a circular economy with companies that have chosen to embrace the ideal of sustainability and develop an innovative business model.

The protagonists of this year’s edition are two international artists and two international fashion designers, selected through an open call launched by Cittadellarte: Augustina Bottoni, Lucia Chain, Huge Sillytoe and Rebecca Sforzani, young talents called upon to create a work with fabrics produced by partner companies, focusing on dialogue and on the enhancement of the textile industry production chain.

In early 2023, the programme will give the four selected artists the opportunity to visit and work actively with the partner companies that have joined the initiative.
These are: Achille Pinto S.p.a, manufacturer of textiles and textile accessories for the main international fashion brands; Albini Group, Europe's largest manufacturer of cotton fabrics for shirts; Erica Industria Tessile, a leading company in the creation of textile prints, original and customised designs; Filatura Astro, eco-sustainable regenerated yarns; G2B S.r.l., a chemical and environmental analysis laboratory working with vertical cultivation from which indigo is obtained; Lampo by Ditta Giovanni Lanfranchi S.p.A., leader in the creation and production of zips for fashion; Lanificio Fratelli Cerruti, a Biella-based weaver for haute couture; Lenzing, world leader in the production of fabrics made from fibres derived from renewable wood raw material; Milior, a producer of high quality fabrics; Officina +39 – Chemistry plus creativity, a chemical company with thirty years' experience dedicated to research and chemical application in textiles; Tessuti di Sondrio, a factory inspired by the century-old local textile tradition of processing cotton, linen, hemp and wool; Tintoria Emiliana, garment-dyed production and sustainable practices; Zegna Baruffa Lane Borgosesia, a manufacturer of 100% Made in Italy fine combed and carded yarns.

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.

Indorama Ventures Public Company Limited (IVL) has signed an ESG-Linked Revolving Credit Facility of €275 million with six syndicate banks, a further boost to the company’s long-standing commitment to sustainability-led corporate financing.

Tied to IVL’s ESG risk rating, the revolving credit facility’s pricing mechanism results in margin adjustments related to management score improvements across the Material ESG Issues as defined by independent sustainability and corporate governance research firms. The facility is available to IVL subsidiaries in Europe for two-years with the option to extend for one more year.

The facility is part of IVL’s corporate financing strategy across a range of instruments linked to the company’s ESG and sustainability commitments. In November 2021, the company issued a THB 10 billion triple-tranche Sustainability-Linked Bond (SLB), the largest SLB issued in Thailand. IVL is on track to achieve its 2025 ESG goals. More ambitious 2030 targets include a 30% reduction in Scope 1 & 2 combined greenhouse gas (GHG) intensity, 15% reduction in energy intensity, 25% use of renewable electricity, 20% reduction in water intensity, 90% diversion of waste from landfill, recycle 1.5 million tons in PET bale input annually.

• ESD protection in harsh environments:
• Polymer-coated chemical-resistant fabrics and fireproof special textiles with expanded electrostatic discharge (ESD) safety function have been developed.
• Graphene nanotubes used as an electrostatic dissipative material make it possible to add ESD protection without compromising resistance to aggressive environments.
• Efficient working loadings starting from 0.06% are sufficient for stable anti-static properties fully compliant with safety standards and position graphene nanotubes far ahead of other conductive materials.

Protective clothing, upholstery, and industrial fabrics that experience harsh conditions require advanced performance. Depending on the final application, specialty textiles can be augmented with flame retardancy, durability, chemical protection, and other properties. Additionally, ESD protection is obligatory in the chemical, rescue, mining, oil & gas, automotive manufacturing, and many other industries that are subject to safety regulations.
 
In applications where multifunctionality of textile is required, graphene nanotubes overcome the limitations of other conductive materials such as unstable anti-static properties; degradation of strength, or chemical or fire resistance; complicated manufacturing processes; dusty production; carbon contamination on the material’s surface; or limited color options. Recent developments show that graphene nanotubes provide ESD protection to textiles in full compliance with safety standards and without degrading the textile’s resistance to harsh environments, greatly enhancing the value of textiles.
 
One such example is textiles coated with fluoroelastomer (a polymer that is highly resistant to chemicals) augmented with graphene nanotubes from OCSiAl. Nanotubes provide the material with surface resistivity of 10^6–10^8 Ω/sq compliant with EN, ISO, and ATEX standards for personal protective equipment. This new technology opens the door for the fabric to be used in high-level protective suits, combining exceptional protection from chemicals with electrostatic discharge protection.
 
Another example is how graphene nanotube technology is being acknowledged as a replacement for metal yarns in fireproof and anti-static textiles, protecting against sparks, splashes of molten metal, high temperatures, and the risk of sudden electrostatic discharge. While metal yarns require a specific knitting process and storage conditions, incorporating nanotubes in a fabric does not require any changes in the manufacturing process as the water-based dispersion is introduced into the fabric at the fluoro-organic treatment stage. The fabric with OCSiAl’s graphene nanotubes has been proven to maintain the pre-set level of ESD protection (surface resistance of 10^7 Ω) after numerous washes.
 
Permanent and stable electrical conductivity, facilitated by graphene nanotubes, is not only a matter of safety but brings additional value in augmenting dust-repellent properties and touchscreen compatibility for comfort and time savings. At the same time, the ultralow nanotube concentrations result in maintained manufacturing processes and mechanical properties, and improve product aesthetics by making it possible to use a wide range of colors. Altogether, these benefits allow textile manufacturers to create next-generation special textiles with expanded functionality.

Monforts will be presenting its finishing technologies at the forthcoming Igatex textile machinery exhibition, which takes place from December 1-4 at the Lahore Expo Centre in Pakistan.

The importance of the textile industry to Pakistan’s economy cannot be overstated – it accounts for 60% of the country’s overall exports and some of its industry’s players are very major employers. In the year to June 2022, Pakistan’s textile exports climbed by 25% to a record value of $19.3 billion according to the country’s Bureau of Statistics, as security of deliveries – especially to Europe and the USA – worked in the country’s favour, in the light of the Covid-19 pandemic and subsequent supply chain issues. It has a key role to play in quickly getting the country back on its feet after the devastation.

Monforts customers in the regions around the country’s three biggest cities of Karachi, Lahore and Faisalbad include all of the main players in the fields of home textiles and denim production, including Afroze, , Al Karam Artistic Milliners, Azgard-9, Crestex, , Gul Ahmed, Interloop, Liberty Mills, Lucky Textile Mills, Mustaqim, Naveena (NDL), Rajby Industries, Sapphire Finishing, Soorty, Style Textile and US Denim.

These companies rely on established Monforts technologies including Montex stentering equipment, Monfortex sanforizing units and Thermex dyeing ranges. The company’s Matex Eco Applicator minimum application system has also proved a big hit in recent years.

Monforts has also achieved considerable success in Pakistan with its Econtrol®* dyeing system  – an effective and established dyeing process. More than 40 Thermex continuous dyeing ranges have been installed in Pakistan in recent years and operator training on the Econtrol®* process by sophisticated technologists is an additional service.

The Econtrol® pad-dry process has a number of immediate benefits. Compared to the common pad-dry-pad-steam process, no salt is used and no steamer is required for a separate fixation step. Compared to the pad-dry-thermofix process, no urea is used and no smoke or deposits are generated, and unlike with the cold pad batch process, direct feedback of the dyeing results ensures no batching time is necessary and guarantees good reproducibility from the lab to bulk production.

An immediate wash off is also unnecessary, allowing for flexible production planning. The process is suitable for pale to dark shades with very good fastness properties. Also waste water treatment is improved by this technology.

Hologenix®, creators of CELLIANT®, began 20 years ago with the idea of improving the quality of people's lives and health with an emphasis on non-invasive, natural, holistic healing. Co-founder and CEO Seth Casden became fascinated with the effect infrared has on the body and worked with a dedicated team to develop and market CELLIANT® infrared technology and thus materials science innovator Hologenix came to be.

CELLIANT, a proprietary blend of IR-generating bioceramics that are ethically sourced, is a unique combination of nature and performance. CELLIANT captures and converts body heat into infrared energy for increased local circulation and cellular oxygenation, resulting in stronger performance, faster recovery and better sleep. It is a key ingredient in textiles, spanning both performance and fashion apparel, sleep and lounge wear, bedding, upholstery, uniforms and medical supplies.

The first partnership Hologenix secured was with the Ireland-based fiber company Wellman International Limited, a fully owned subsidiary of Indorama Ventures and a pioneer in recycling technologies. Hologenix still works with them today, a tribute to the company’s ability to form long-term partnerships with like-minded organizations, and their joint project of pure white CELLIANT rPET fiber was shortlisted for a prestigious Drapers Sustainable Fashion Award earlier in the year.

On the brand side, many of the first brands to incorporate CELLIANT were in the sportwear industry, including Adidas, Reebok, Saucony, Eastern Mountain Sports, Sierra Designs sleeping bags and Superfeet insoles.

In 20 years, Hologenix has achieved many scientific milestones, and CELLIANT has been and continues to be rigorously tested by a Science Advisory Board composed of experts in photobiology, nanotechnology, sleep medicine, and diabetes and wound care. The Science Advisory Board has overseen nine peer-reviewed published studies that demonstrate CELLIANT’s effectiveness and the benefits of infrared energy.

Looking ahead, Hologenix is continuing to research applications for CELLIANT in the agriculture industry and wound healing and diabetes. Expansion into the FemTech market with both product applications and scientific research about the benefits of infrared for women’s health issues is also on the horizon.
