From the Sector

Majocchi, an Italian textile manufacturer, reports that it has achieved functional and visual appeal with its key fabrics since installing Baldwin Technology Co. Inc.’s corona surface treatment technology.  

Based in Tavernerio (Como), Majocchi has a history of being a technological innovator in the textile industry. Within a decade of its conception in 1941, Majocchi became a global supplier of waterproof cotton for rainwear manufacturers. In the 1960s, the company began producing nylon and technical fabrics, which paved the way for it to become a leading provider of textiles for urban fashion, technical workwear and the military today.

Majocchi has partnered with U.S -based Baldwin Technology Co. to utilize its unrivaled corona surface-treatment technology to produce superior wettability and adhesion.  

Corona treatment is a technique that temporarily modifies a substrate’s surface tension  properties. The corona oxidation process improves the penetration and absorption of liquids on cellulosic and synthetic fabrics. Utilizing corona treatment before resin application on fabrics such as lycra and nylon facilitates superior adhesion and resin distribution. As a result, corona-treated fabrics provide exceptional color and tonal quality.  

Majocchi uses Baldwin’s Corona Pure Model to apply polyurethane and acrylic-based coatings to its fabrics. The system allows Majocchi to administer a controllable, uniform coating to achieve the desired functionality and aesthetics.

The system is 2,000 millimeters wide with a discharging station and four ceramic electrodes designed for textile applications with the flexibility of customizing plasma dosage for a given fabric structure, width and process speed. The Corona Pure model allows for fabric treatment up to 300 gr/m² in thickness. The system is customizable, with single-sided and dual-sided treatment capabilities. The “Easy Change” feature allows for a seamless replacing of electrodes and rapid cleaning and removal of fiber and dust residue, maintaining optimal exhaust air flow. The treatment system is built with a swiveling housing mechanism, which provides clearance for changes in textile thickness and protects the ceramic electrodes.

The American company WPT Nonwovens invests in a new thermobonding line for filter media. Trützschler Nonwovens teamed up with Schott & Meissner to deliver a state-of-the-art, high-capacity line including the T-BLEND fiber preparation system, two TWF-NC roller cards and Schott&Meissner’s high-speed “Speedliner” belt oven.

Air conditioning systems are not only an integral part of many buildings all over the world. They are vital components in cars, trucks, planes and other. Home and Vehicle Air Conditioning (HVAC) systems often rely on thermo- or through-air bonded nonwovens for air filtering.

WPT Nonwovens is a specialist not only for filtration media but also for nonwovens used in the medical, hygiene and industrial sectors. The US-based company started its business in 2008 and quickly became a trusted supplier of spunbonded, needle-punched, wet-laid and carded nonwovens.

To enable further growth, WPT Nonwovens now decided to invest in a new through-air bonding line. The Trützschler machinery has been selected to ensure reliable fiber preparation and web forming processes for various special, technically demanding filtration media.

The start-up of the through-air bonding line is planned for the 3rd quarter 2023.

Carbios has strengthened its leadership team with the appointment of Martine Brisset as Senior Vice President from 1 January 2023. Martine will manage the Biodegradation Division and supervise the Human Resources, Legal, Regulatory, Project Management, Quality Health and Safety departments. Martine Brisset joins the Group’s Executive Committee, as does Delphine Denoizé, who remains Innovation Programs Funding, Regulation and LCA Director with an expanding team.

Martine Brisset has over 30 years of General Management experience in international groups within the plastic and paper packaging industry, most notably at Amcor, Huhtamaki, Linpac and Klockner Pentaplast.  Since 2021, she has held the position of General Manager of Carbiolice in order to integrate this high-potential subsidiary dedicated to biodegradation within the Carbios Group. In her new position as Senior Vice President of Carbios, her main mission will be to successfully deploy the biodegradation technology, facilitate the international expansion of Carbios’ activities, organise the recruitment and training of the Group’s employees. With numerous recruitments planned throughout the company in 2023, building Carbios’ attractivity will be a strategic topic.

After several years working in innovation within the agricultural industry, Delphine Denoizé joined the Carbios in 2016 and was one of its first twenty employees. Initially in charge of Innovation Funding and Regulation, then Project Management for PET biorecycling, she now oversees all the Group’s projects. Her responsibilities include French and European public funding for innovation, regulatory compliance of processes and products around the world, and assessment of their environmental impact through specific tools such as Life Cycle Assessment.

For the third time, nova-Institute awards the “Cellulose Fibre Innovation of the Year” award in the frame of the “Cellulose Fibres Conference 2023” (8-9 March 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.

For the first time in two years, global automotive production recorded a significant increase in full-year 2022 with 82.0 million vehicles produced (2021: 77.2 million vehicles) and growth of 6.2%, driven by the regions Asia and North America, but remained below 2019 levels.
Autoneum's revenue in local currencies increased significantly by 8.5%, largely due to inflation-related compensation. In the regions Europe and Asia, Autoneum's production volumes developed below market. Compared to the July 2022 estimate, revenue was around CHF 90 million lower than assumed due to volume factors. The strong fluctuations in production volumes due to vehicle manufacturer supply chain issues continued in 2022 and were exacerbated by the war in Ukraine in Europe and by COVID-related lockdowns in Autoneum's Asian main market China. Consolidated revenue in Swiss francs increased by 6.1% year-on-year to CHF 1 804.5 million (2021: CHF 1 700.4 million) due to the strong Swiss franc.

Revenue development in the regions
In local currencies, revenue of Business Group Europe increased by 2.7%, while production volumes of vehicle manufacturers decreased by 1.3%. The growth in revenue resulted from inflation compensation, while Autoneum's production volumes were significantly lower compared to the previous year. Business Group North America increased its revenue in local currencies by 11.0%. The number of vehicles produced increased by 9.7% year-on-year. Volume development at Autoneum’s North American plants clearly improved compared with 2021 due to the allocation of semiconductors to the vehicle models supplied by Autoneum. Revenue of Business Group Asia declined by 2.7% in local currencies, and thus was significantly below the market (+7.7%). Autoneum's production facilities in its main market China are located in regions that were hit particularly hard by the COVID-related lockdowns. Growth in China was also driven by Chinese vehicle manufacturers, with whom Autoneum generated only little revenue last year.
Business Group SAMEA (South America, Middle East and Africa) achieved hyperinflation-adjusted revenue growth in local currencies of 65.2% year-on-year. This increase was mainly due to inflation compensation and in terms of volume slightly outperformed the market, which grew by 7.5%.

Due to significantly lower production volumes in Autoneum's regions Europe and Asia of around CHF 90 million compared to the half-year estimate and further increases in energy costs in the second half of the year, Autoneum expects the full-year 2022 result to be at the lower end of the guidance published on June 15, 2022.

The full year-end financial statements and the Annual Report 2022 will be presented at the Media Conference on March 1, 2023.

Effective March 1st, Ib Jensen takes over from Jan Secher as Chief Executive Officer of Perstorp Group, a specialty chemicals company headquartered in Malmö, Sweden and since 2022 part of PETRONAS Chemicals Group Berhad (PCG).

Ib Jensen is a highly respected senior industry executive with a long career as CFO and extensive experience from M&A and integration of acquired companies, something that will be required in the next phase for Perstorp.

After more than 9 successful years as the CEO of Perstorp Group, Jan Secher has decided to step down. This decision is based on a personal direction set more than a year ago, prior to the acquisition by PCG, allowing for a full search process to be conducted for his replacement. Ib Jensen has been CFO of Perstorp for the past year and was considered the most qualified candidate based on his knowledge of the company, long term experience of the specialty chemicals industry and high level of appreciation in both Perstorp as well as in PCG. Previous experience include CFO and executive roles within Finance and IT at companies such as Arxada, Lonza, Syngenta, Danisco and LEGO.

Jan Secher remains in the CEO role until March 1st and will thereafter serve as an advisor to the new CEO and the Chairman, focusing on strategy and transferring external relationships. Monica Jönsson, currently deputy CFO, will take on the role as CFO when Ib Jensen assumes the position as CEO. PCG is fully committed to the Executive Leadership Team of Perstorp and expects the team to continue the successful integration work as well as dealing with the volatile global macro situation.

Carbios and Novozymes announced an exclusive long-term global strategic partnership. This major agreement ensures the long-term production and supply of Carbios’ proprietary PET-degrading enzymes at an industrial scale for the world’s first biological PET-recycling plant due to start production in 2025 in Longlaville (France), as well as Carbios’ future licensee customers.
 
Carbios and Novozymes have had a partnership since 2019 to develop enzyme-based solutions and address  the sustainability challenge of plastic pollution, both within PET-recycling[1] and PLA-biodegradation[2].  Building on the current Joint Development Agreement (JDA), under the new agreement, Carbios and Novozymes will extend their collaboration to develop, optimize and produce enzymes that will subsequently be supplied by Novozymes to all licensees of Carbios’ technology.  The new agreement grants both parties exclusivity in the field of the partnership.
 
The strategic partnership supports the large-scale industrial deployment of Carbios’ patented PET-recycling technology starting with Carbios’ future industrial reference unit in Longlaville (France), which will be the world’s first biological PET-recycling plant. Construction will begin later this year, and both building and operating permits having been filed with local authorities.  Production at the plant is set to start in 2025 and the processing capacity will be 50,000 tonnes of waste per year.

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.
