• Standard assesses fibre release, biodegradation and ecotoxicity for the first time

Testing service provider Hohenstein has worked with the project partners Trigema, Freudenberg, DBL ITEX and Paradies to create a new standardized test method for detecting and classifying the environmental effects of textiles during washing. DIN SPEC 4872 combines analysis of fibre release, biodegradability and ecotoxicity. The test method according to DIN SPEC 4872 shows how many fibres are released during textile laundering, how well these fibres degrade in wastewater and how harmful the fibre residues are to the environment.

Studies have shown that washing textiles releases microfibres into the wash water, which cannot be sufficiently retained by wastewater treatment plants. Synthetic fibres pose the greatest risk to the environment because of their longevity and inability to biodegrade. However, Hohenstein project manager Juliane Alberts does not give the all-clear for biodegradable fibres and natural fibres: "Biodegradability alone does not mean that pure natural fibres, for example, are completely harmless to the environment. They, too, remain in ecosystems until they completely degrade and can also have a negative impact. In addition, additives, auxiliaries or finishes used in textile production can further slow the degradation process and leach into the environment."

The new standard enables textile producers and suppliers to test, evaluate and compare products for fibre release during washing and environmental impact. Juliane Alberts sees this systematic evaluation as an opportunity for the textile industry to take the initiative on environmental impact: "Our reliable data can be used as a basis for more targeted product development. This is a way to actively and consciously control further environmental pollution."

Sustainable solutions provider Perstorp has added new corporate sustainability targets, for water and waste, to its sustainability strategy. Its long-term sustainability ambition is to become Finite Material Neutral, which involves water and waste, along with raw materials, energy and catalysts. In 2021 the company set its first 2030 targets, for greenhouse gas emissions (using approved science-based targets) and (eco) toxic impact. Now Perstorp has added new sustainability targets that will address its long-term ambition.

These new 2030 corporate targets (all measured using 2019 as the base year) are:

• 30% absolute reduction of freshwater consumption
• 30% absolute reduction of hazardous waste directed to disposal
• 30% absolute reduction of non-hazardous waste directed to disposal

"Fresh water consumption and waste are two areas of big importance in reducing our environmental impact and working toward increased circularity," says Anna Berggren, Vice President Sustainability at Perstorp Group. "Fresh water scarcity is already a fact around the world, and we have a responsibility to reduce our consumption and utilize alternative water sources. We must also minimize waste generation and find new circular solutions of reusing and recycling the waste streams into new products, either ourselves or so that a third party can use them as raw material. We have set ambitious and absolute sustainability targets, that are to be achieved regardless of production growth. To be able to reach these targets we have several large projects planned that will contribute significantly."

All Perstorp production plants use water for multiple purposes, including, for example: for cooling, as a solvent for chemical reactions, as a carrier for products, and as a heat-transfer medium. One way to reduce fresh water consumption is to purify and recycle wastewater. Perstorp sees this as an important core technology and is planning to invest in wastewater recycling projects at several of its production sites.

A key to reducing waste directed to disposal is to develop circular solutions that use waste streams as raw materials for new products. One example is Project Air, in which captured carbon dioxide together with residue streams from Perstorp's production plant in Stenungsund, Sweden, will serve as raw material for production of sustainable methanol that will replace all the virgin fossil methanol used by Perstorp in Europe.

The Science Based Targets initiative (SBTi) has approved Autoneum’s science-based emissions reduction targets. The validation by the SBTi is an important milestone in Autoneum’s efforts to reduce its direct and indirect greenhouse gas (GHG) emissions along the entire value chain.

Recognizing the serious environmental challenges facing the world today and the resulting need for rapid and significant reductions in global CO₂ emissions, Autoneum has committed to reducing its absolute scope 1 and 2 GHG emissions by 20% by 2027 from a 2019 base year. The Company also commits to reduce its absolute scope 3 GHG emissions from purchased goods and services by 20% within the same timeframe. Autoneum’s GHG emission reduction targets were validated by the SBTi on January 12, 2023, and are in line with the goals of the Paris Agreement to limit global warming to well below 2°C. The Company is thus taking another important step toward a sustainable future of mobility.

An overview of all emissions reduction targets and activities implemented by Autoneum in 2022 will be published in the Company’s Corporate Responsibility Report 2022 on March 24, 2023.

The conference advisory board nominated six remarkable products, including cellulose fibres from textile waste, banana production waste and bacterial pulp, a novel technology for producing lyocell yarns and a hygiene product. The innovations will be put to the vote of the conference audience on the first day of the event, with the awards ceremony taking place in the evening. The innovation award “Cellulose Fibre Innovation of the Year 2023” is sponsored by GIG Karasek (AT).

Here are the six nominees
Vybrana – The new generation banana fibre – GenCrest Bioproducts (India)
Vybrana is a Gencrest’s Sustainable Cellulosic Fibre upcycled from agrowaste. Raw fibres are extracted from the Banana Pseudo stem at the end of the plant lifecycle. The biomass waste is then treated by the Gencrest patented Fiberzyme technology. Here, cocktail enzyme formulations remove the high lignin content and other impurities and help fibre fibrillation. The company's proprietary cottonisation process provides fine, spinnable cellulose staple fibres suitable for blending with other staple fibres and can be spun on any conventional spinning systems giving yarns sustainable apparel. Vybrana is produced without the use of heavy chemicals and minimized water consumption and in a waste-free process where balance biomass is converted to bio stimulants Agrosatva and Bio Fertilizers & organic manure.

HeiQ AeoniQ™ – technology for more sustainability of textiles – HeiQ (Austria)
HeiQ AeoniQ™ is the disruptive technology and key initiative from HeiQ with the potential to change the sustainability of textiles. It is the first climate-positive continuous cellulose filament yarn, made in a proprietary manufacturing process and the first to reproduce the properties of polyester and nylon yarns in a cellulosic, biodegradable, and endlessly recyclable fibre.
HeiQ AeoniQ™ can be manufactured from different cellulosic raw materials such as pre- and post-consumer textile waste, biotech cellulose, and non-valorized agricultural waste, such as ground coffee waste or banana peels. It naturally degrades after only 12 weeks in the soil. Each ton of HeiQ AeoniQ™ saves 5 tons of CO2 emissions. The first garments made with this innovative cellulosic filament fiber were commercially launched in January 2023.

TENCEL™ LUXE – lyocell filament yarn – Lenzing (Austria)
TENCEL™ LUXE is LENZING’s new versatile lyocell yarn that offers an urgently needed sustainable filament solution for the textile and fashion industry. A possible botanical alternative for silk, long-staple cotton, and petrol-based synthetic filaments, is derived from wood grown in renewable, sustainably managed forests, and produced in an environmentally sound, closed-loop process that recycles water and reuses more than 99 % of organic solvent. Certified by The Vegan Society, it is suitable for a wide range of applications and fabric developments, from finer high fashion propositions to denim constructions, seamless and activewear innovations, and even agricultural and technical solutions.

Nullarbor™ – Nanollose & Birla Cellulose (Australia/India)
In 2020, Nanollose & Birla Cellulose started a journey to develop and commercialize tree-free lyocell from bacterial cellulose, called Nullarbor™. The name derives from the Latin “nulla arbor” which means “no trees”. Initial lab research at both ends led to a joint patent application with the patent “production of high-tenacity lyocell fibres made from bacterial cellulose”.
Nullarbor is significantly stronger than lyocell made from wood-based pulp; even adding small amounts of bacterial cellulose to wood pulp increases the fibre toughness. In 2022, the first pilot batch of 260kg was produced with 20 % bacterial pulp share. Several high-quality fabrics and garments were produced with this fibre. The collaboration between Nanollose & Birla Cellulose now focuses on increasing the production scale and amount of bacterial pulp in the fibre.

Circulose® – makes fashion circular – Renewcell (Sweden)
Circulose® made by Renewcell is a branded dissolving pulp made from 100 % textile waste, like worn-out clothes and production scraps. It provides a unique material for fashion that is 100 % recycled, recyclable, biodegradable, and of virgin-equivalent quality. It is used by fibre producers to make staple fibre or filaments like viscose, lyocell, modal, acetate or other types of man-made cellulosic fibres. In 2022, Renewcell, opened the world’s first textile-to-textile chemical recycling plant in Sundsvall, Sweden – Renewcell 1. The plant will eventually reach 120,000 tons of annual capacity.

Sparkle sustainable sanitary pads – Sparkle Innovations (United States)
Globally, around 300 billion period products are discarded every year, resulting in millions of tons of non-biodegradable waste. Since most conventional sanitary pads contain up to 90 % plastics, they do not biodegrade for around 600 years. Sparkle has designed sustainable, plastic-free, biodegradable and compostable Sparkle sanitary pads. From product to packaging, they are made up of around 90 % cellulose-based materials with top sheet, absorbent core, release paper, wrapping paper and packaging made of cellulose-based fibres. Whether Sparkle pads end up in a compost pit, are incinerated or end up in a landfill, they are a more sustainable alternative compared to conventional pads that contain large amounts of plastics, complex petro-chemical based ingredients and artificial fragrances. When tested according to ISO 14855-1 by a leading independent lab in Europe, Sparkle pads reached over 90 % absolute biodegradation within 90 days in commercial composting conditions.

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.

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.
