From the Sector

In a roundtable discussion during the recent Innovate Textiles & Apparel (ITA) textile machinery exhibition, imogo Founding Partner Per Stenflo and representatives from a number of like-minded European companies discussed the opportunities for new spray application technologies for the dyeing and finishing sector.

These technologies can achieve tremendous savings for manufacturers compared to traditional water-intensive processes it was explained at the event, held online from October 15-30th.

Pioneer
imogo – one of the latest companies to join TMAS, the Swedish Textile Machinery Association – is one of the key pioneers in this area with its Dye-Max system. Dye-Max spray dyeing technology can slash the use of fresh water, wastewater, energy and chemicals by as much as 90% compared to conventional jet dyeing systems. This is due to the extremely low liquor ratio of 0.3-0.8 litres per kilo of fabric and at the same time, considerably fewer auxiliary chemicals are required to start with.

Obstacles
Such technologies, however, face a number of obstacles to adoption and during the ITA discussion it was agreed that 2020 has not provided the ideal climate for adventurous investors. “The textile industry is quite conservative and is definitely in survival mode at the moment and it is not the time to be a visionary,” said Stenflo. “Day to day business is about staying alive – that’s the reality for many of our customers.” Nevertheless, all of the panellists agreed that sustainable production will remain top of the agenda for the textile industry in the longer term and spray technologies for dyeing and finishing processes will be a part of it.

“Any investment in something new is a risk of course, and we have to be able to explain and convince manufacturers that there’s a good return on investment, not only in respect of sustainability, but in terms of making good business sense,” said Stenflo. “Here we could use the help of the brands of course, in putting pressure on their suppliers to be more sustainable. Governments also have a role to play, in providing incentives for producers to move in the sustainable direction. Sustainability alone will never cut it, there has to be a business case, or it won’t happen.”

Marketing
The marketing of sustainable new fibers is comparatively easy for the brands compared to explaining the difficult textile processes and the chemistries involved in fabric and garment production, he added.

“These fibers, however, currently go through all the same dirty processes that we need to get away from, so it must happen,” he said. “In developing our technologies, it has been important for us to avoid disrupting existing supply chains, stick with using off-the-shelf chemistries and dyes, and involve the dye manufacturers who are an essential part in how operations are driven today. “In fact, collaboration across the entire textile supply chain – from the brands right back to the new technology developers – is essential in moving the sustainability agenda forward.

Business models
“We are also looking into new business models in terms of how to reduce or lower the thresholds for investment and minimise the risk for the manufacturers who are looking to be the innovators,” he concluded. Also taking part in the ITA roundtable discussion were Simon Kew (Alchemie Technology, UK), Christian Schumacher (StepChange Innovations, Germany) Tobias Schurr (Weko, Germany), Rainer Tüxen (RotaSpray, Germany) and Felmke Zijilstra (DyeCoo, Netherlands).

European innovations
“It’s fantastic that all of this innovation is taking place in Europe based on established know-how and forward thinking,” said TMAS Secretary General Therese Premler-Andersson.

“Spray application technologies are a perfect illustration of how new digital technologies can lead to more sustainable production, in this case by replacing water-intensive processes with the highly precise and controlled application of dyes and chemistries as vapour.
“There was a major project by the Swedish research organisation Mistra Future Fashion recently, involving many brand and academic institute partners. The project’s Fiber Bible 1 and 2 reports conclude that it’s very difficult to make assumptions that one fiber is better than another, because it’s so much about how fabrics and garments are being produced from them. The study also found that 55% of the chemicals used in a garment comes from the dyeing. This is where a number of TMAS companies can make a difference.
“An organic or recycled cotton t-shirt is not automatically more sustainable than a conventional cotton t-shirt, or even one made from synthetics – the alternative fibers are a good start but you have to consider the entire life cycle of a garment, and that includes the smart technologies in textiles production.
“TMAS members – backed by Swedish brands and advanced research institutes – are playing an active part in pushing forward new concepts that will work, and I have no doubt that digitalisation now goes hand in hand with sustainability for the textile industry’s future.”          

Rester Oy, which is developing the plant in Paimio, recycles companies' end-of-life textiles, and Lounais-Suomen Jätehuolto Oy (LSJH), which will hire a production area at the same facility, processes households' end-of-life textiles. The plant will process 12,000 tonnes of end-of-life textiles every year, which represents about 10% of Finland’s textile waste.

The textile industry’s end-of-life textile problem is intolerable. Natural resources are increasingly used to manufacture products, but these materials are lost at the end of their life cycle. About 100 million kilograms of textile waste are generated annually in Finland alone. Reusing this material could reduce the textile industry’s carbon footprint and significantly reduce the use of natural resources.

Rester Oy and LSJH will drive the textile sector towards a circular economy and begin processing textile waste as an industrial raw material. The Nordic countries’ first industrial end-of-textile refinement plant will open in Paimio in 2021. The 3,000-square-metre plant is being developed by Rester Oy, which recycles companies' end-of-life textiles and industrial waste materials. LSJH, which processes households’ end-of-life textiles on its production line, will hire part of the plant.

Outi Luukko, Rester Oy’s board chair, says, “The processing plant will begin a new era of textile circular economy in Finland. As industry pioneers, we are launching a system change in Scandinavia. The transition of the textile industry from a linear model to a circular economy is essential, as virgin materials cannot sustain the current structure of the textile industry. And why should it, when there is so much recyclable material available?”

From the perspective of Rester Oy’s main owner, work clothing supplier Touchpoint, the circular economy plant not only represents resource efficiency, but is also necessary from the perspective of the entire life cycle of a responsible work clothing collection.

Luukko adds, “Finding a local solution to a global problem is a huge leap in the right direction and raises Finland's profile as a pioneer of circular economy."

The future plant will be able to process 12,000 tonnes of end-of-life textiles annually, which represents about 10% of Finland’s textile waste. Both production lines produce recycled fibre, which can be used for various industrial applications, including yarn and fabric, insulating materials for construction and shipping industries, acoustic panels, composites, non-woven and filter materials, and other technical textiles, such as geo-textiles.

LSJH is piloting a full-scale refinement plant

LSJH has launched a pilot production line for processing households' end-of-life textiles. Unfortunately, consumers' end-of-life textiles are heterogeneous, making them a challenging raw material for further processing. Before processing, the textiles are sorted by material into various fibre classes using optical identification technology developed by LSJH and its partners. This ensures the quality of the raw material and the resulting fibre products.

Jukka Heikkilä, managing director for Lounais-Suomen Jätehuolto, explains: “On the basis of the experiences gathered from the pilot project, Lounais-Suomen Jätehuolto is preparing a full-scale refinement plant in the Turku region. As soon as 2023, the plant will process Finnish households' end-of-life textiles. The project involves all waste treatment plants owned by Finnish municipalities.”

Paimio has ambitious goals for circular economy companies

Rester’s initiative aims to create a circular economy cluster in Paimio that combines the processing and reuse of end-of-life textile fibres. Paimion Kehitys Oy, which is owned by the City of Paimio and the local association of enterprises, supports the development of circular economy companies in Paimio.

Mika Ingi, managing director for Paimion Kehitys Oy, says, “We want to step out of our traditional municipal role and create significant added value for everyone taking part. That is why we are involved in the development of a new modern service model based on ecosystem thinking. We are piloting the textile cluster, followed in the coming years by clusters focusing on plastic, construction, and energy. The aim of our service is to support and help develop new profitable business by bringing circular economy companies and their potential customers to innovate together."

The foundation stone of the processing plant was laid today (18 August 2020). The processing plant will begin operations in February 2021.

• Bemberg™ presents a great deal of novelties with a true key-statement for sustainability: Let’s Make it Circular!
• The lifespan of Bemberg™’s regenerated cellulose fiber Cupro derived from cotton is fully circular: from the source to manufacturing.

“Sustainability is the founding pillar of our company,” says SHUNSUKE SATO, sales manager of Bemberg™ by Asahi Kasei. “Indeed, the smart fiber is made from a cotton linter which is pre-consumer material, a natural derived source, that doesn’t deplete forestry resources”.

In Bemberg™’s production the whole sustainable closed-loop process is supported by the LCA study, signed by ICEA (Istituto per la Certificazione Etica e Ambientale) and validated by President of Ecoinnovazione Paolo Masoni ex Research Director of ENEA (Ente per le Nuove tecnologie, l’Energia e l’Ambiente).

While recyclability is granted by the Global Recycle Standard - GRS certification by the renown Textile Exchange (an influential guarantee that involves the whole production process and supply chain behind the company’s smart yarns), Bemberg™ yarns are also entirely biodegradable and ecotoxicity-free - meaning that at the end of their life circle they break down into the environment leaving no trace in terms of toxic substances as attested by the Innovhub-SSI report.

A special focus deserves Velutine™ Evo, the new fibrillation finishing technology for Bemberg™ fabrics only that guarantees another level of sustainable benefits without sacrificing the Bemberg™ amazing and unique touch. As part of the company’s continuous innovation, Velutine™ Evo brings better environmental, energy and water profiles for the benefit of Bemberg™ partners in the manufacture of their ranges.
The sustainable achievements of the new finishing technology have been measured by LCA - Life Cycle Assessment study by ICEA and proved to guarantee environmental benefits such as -16.5% of greenhouses gas emissions and -21% of overall consumption of energy resources. On top of that Velutine™ Evo means also -20.5% of electricity savings, -15.9% of steam production and -19.5% of water consumption.

The first Bemberg™ partner to present a commercial collection enriched by Velutine™ Evo is the Portuguese Matias & Araújo. With an innovative spirit, dynamism and a determined entrepreneurial spirit, the company is a leading knitwear producer for the textile industry.

Bemberg™ collaborated also with the premium brand CAALO that is making its mark in the outerwear market with its Sustainably produced Functional-Luxury proposal. For SS20, CAALO uses Bemberg™ lining because of the sustainability properties and it’s unique colour.

CAALO uses as much eco-friendly and sustainable materials as possible without compromising on design or quality. This Bemberg™ lining was a perfect fit. This versatile blazer features a removable hood, hidden welt pockets, button closure, and removable cargo pockets.

Hexcel has joined forces with a Lyon-based startup, LAVOISIER COMPOSITES. This company has developed CARBONIUM®, a new generation of material sourced entirely from carbon composite by-products generated by the French aerospace sector.

Hexcel supplies high-performance composite materials for the latest generation of aircraft such as the Airbus A350 XWB (53% composite structure). This has greatly contributed to the reduction of the aircraft's weight, thereby reducing its fuel consumption and carbon footprint. Composites are a significant first step toward tackling environmental and economic challenges, and eco-sourcing of the industry by-products also plays a key role.

CARBONIUM®, which was developed with a process based on three patents pending, reduces overall environmental impact by 40-50%, compared to equivalent products derived from virgin materials. Based on the "climate change" factor, the life cycle assessment carried out with Hexcel revealed that the up-cycling of by-products from the aerospace composites industry leads to a reduction in CO2 emissions of 13kg per kg of CARBONIUM® used.
In its first year of operation, LAVOISIER COMPOSITES has already enjoyed commercial success, including the launch of two top-of-the-range watch models by Swiss luxury watchmaker ULYSSE NARDIN using this new material.

From aircraft fuselages to watchmaking, the composites manufacturing cycle presents opportunities for reducing our impact on the environment.
