A new generation of ecological PU coatings with water vapour permeability

Today, nearly all “breathable“ PU direct coatings are applied from solvent systems. These products partly contain very harmful and environmentally hazardous solvents.
To solve the “solvent“ problem, RUDOLF GROUP developed ECO-VENT®:

A water-based coating solution that opens up new perspectives for numerous coated fabrics, which are permeable to water vapour and, thus, breathable.
The optimum PFC-free, waterproof and breathable protective clothing can be finished with RUDOLF’s cluster of supreme technologies:

• Outer fabric finished with BIONIC-FINISH®ECO
• Direct coating made from ECO-VENT®
• Lining with moisture control due to hydrophilic HYDROCOOL®

The EU-funded Project, in which Devan Chemicals is a key partner, held a kick off meeting end of February 2019 at the EU Commission in Brussels, Belgium. The project consortium, led by Belgian R&D centre CENTEXBEL, consists of 17 European partners from across the value chain including design, manufacturing, NGOs, and research and innovation.

The focus of the consortium is on coated and painted textiles and plastic materials which are currently not recyclable. Ambitious plastic recycling targets of 50% have been set by the European Plastics Industry, and to meet these targets, smart solutions to enable the circular use of textile and plastic parts with multi-layer coatings must be considered.

DECOAT has therefore been established to investigate triggerable smart polymer material systems and appropriate recycling processes. The solutions will be based on smart additives (like microcapsules or microwave triggered additives) that will enable the efficient of coatings and other finishes, activated by a specific trigger (heat, humidity, microwave, chemical) to permit recycling.        

Devan’s specific role is in the development of microcapsules that will release its active core on application of a certain trigger (e.g. heat) at the end of life of the article. This active core material may be something that, for example, will promote the detachment of different coating layers (by separating them), opening the possibility for recyclability/re-use of the base materials. Different active core ingredients will be evaluated, and Devan will develop processes for each type of core ingredient and for each type of coating layer/matrix.

The bold aim of the four-year project is to decrease landfill by 75% of coated articles that are presently difficult to recycle, such as clothing, electronic goods and automotive components. A reduction in the carbon footprint by at least 30% for the considered products is aimed for. By enabling the recycling of such materials, DECOAT is expected to generate in the medium term a new market valued at over 150 million Euros in Europe.

• STOP TALKING. START ACTING.
• Climate change is real. And so is the responsibility of every human being to help in reducing waste.

We no longer want to talk about sustainability, we want to act. For January, PREMIUM is partnering with Spanish fashion label and sustainable clothing pioneer ECOALF. The brand will present its lifelong mission and latest collection in a dedicated space as well as an art installation together with conceptual artist Juan Garaizabal.

"2019 is all about digital first and an active debate about social and environmental issues. Transparency and sustainability are key words. By reducing plastic waste on all our shows, teaming up with ECOALF and giving this wonderful brand dedicated space and time for spreading their message, we are taking steps into right direction. Every little action counts. We should talk about the things we do more instead of talking about what we are not doing. We all need to wake up. Now.” – Anita Tillmann, CEO PREMIUM Group

ECOALF creates high-quality garments using recycled materials collected from the bottom of our oceans. Commitment, sustainability and innovation are at the core of everything the company does, resulting in both conscious and stylish urban, adventure, knitwear and activewear pieces.   
 
“I love collaborating with people that also believe we have the opportunity to change the world for the better. It’s no longer about what you do, but how you do it. It is important to stand up for what you believe in, because fashion cannot just be about looking good.” – Javier Goyeneche, President and Founder of ECOALF. 

On Wednesday, January 16th, at 10am and 2pm, Goyeneche will present his brand’s values, philosophy and way of working on the experience floor of SHOW&ORDER X PREMIUM at Kühlhaus, right next to the STATION area. Show visitors, media and other exhibitors are invited to listen, learn and discuss.   
 
The art piece in partnership with Garaizabal unveiled at PREMIUM on January 15th is filled with waste to portray our everyday reality, and purposefully interactive so that visitors can throw their own trash inside the installation. The aim is to educate about correct waste disposal and show that every individual’s decision matters: Stop, Think, Act.

• conceptual and commercial garments presented at exhibition in London

After two years of research Mistra Future Fashion is honoured to present, in collaboration with Centre for Circular Design at University of the Arts London and Filippa K, an exhibition pushing the limits of ‘fast’ and ‘slow’ fashion. Started in 2017, the industry-embedded project Circular Design Speeds takes a unique systemic approach, showcasing what could be accomplished using existing value chains as well as what the future of sustainable fashion holds. Ground-breaking textile research from University of the Arts London is questioning normative use and design of garments in creating prototypes to be worn across a spectrum of 24 hours to 50 years. By implementing research into existing value chains, Filippa K have produced a coat that is 100% recycled and recyclable, as well as a concept dress that is 100% bio-based and biodegradable. The research results and garments will be presented at the launch event at the University of the Arts London, on November 23rd and open to public on the 24th and 25th of November.

On Friday November 23rd the exhibition Disrupting Patterns: Designing for Circular Speeds opens up at University of the Arts London. The exhibition is the results of a two-year research project called Circular Design Speeds aiming at pushing the limits of ‘fast’ and ‘slow’ fashion by testing new concepts for sustainable design in an industry setting. On display are exploratory prototypes, as well as commercial garments produced by industry partner Filippa K using existing value chains. In addition, research results on innovative materials, consumer acceptance, composting studies and Life Cycle Assessments are presented. The aim of this project is to implement research results in a real fashion industry context, focusing on speed of use and maximising fabric value retention in products.

The Service Shirt developed by Professor Rebecca Earley is designed to last for over 50 years. The concept garment explores the multiple complexities, challenges and opportunities associated with design for circular business models in extended use contexts. The Service Shirt was designed as a ‘deliberate extreme’ to have a total lifecycle of 50 years. This lifecycle includes in-house and external remanufacturing processes, as well as various use cycles – often moving between single ownership and rental and sharing contexts. It becomes the lining for a jacket and then crafted in to fashion accessories, before finally being chemically regenerated in the year 2068.

On the opposite side of the spectrum the Fast-Forward concept, developed by Prof Kay Politowicz and Dr Kate Goldsworthy, explores alternative modes of production and use for a sustainable ‘fast-fashion’ application. Advantages with regards to climate impact are enabled through lighter material choices, nonwoven fabric production, no launder, clear routes to recovery and redistributed manufacturing systems. A sliding scale of ‘speed’ from ultra-fast forward through to a more widely accepted length of use, with adaptations to production processes and end of life, is presented. The prototypes are made from a new bio-based nonwoven material co-developed with Dr Hjalmar Granberg at RISE Research Institute of Sweden & University of the Arts London. The composition of the paper is a mix of cellulose pulp and bio-based PLA fibre, making the garment 100% biodegradable or recyclable in existing paper recycling systems.

Working closely with industry partner Filippa K made commercial testing possible. By implementing research into existing value chains, Filippa K was able to produce a coat that is 100% recycled and recyclable, as well as a concept dress that is 100% bio-based and biodegradable. The garments are a part of Filippa K’s Front Runner series and will be available in selected stores on November 26th. With a focus on products’ length of use and maximizing fabric value retention, Filippa K are dedicated to becoming fully circular by 2030.

“Being part of the fashion industry comes with many challenges, especially when considering the fact that we are the second most polluting industry after oil. Our industry needs to change and we believe adapting to circular models, like nature’s ecosystem, is one important solution. We want to be able to offer beautiful clothing and to make business within the planetary boundaries.”
- Elin Larsson, Sustainability Director, Filippa K

To validate the design research presented, a Life Cycle Assessment was performed on the prototypes. Mistra Future Fashion affiliated Dr. Greg Peters, Chalmers University of Technology, together with additional LCA Researchers at RISE, conclude that the production of fibres and fabrics are the main processes impacting the environment during the garment life cycles. Therefore, to extend the lifetime of existing garments and design for re-use, as done in the Service Shirt, is indeed the superior alternative compared to a reference garment.

“Compared with garments of the same mass, the extended life garments represent a large improvement in environmental performance over the reference garments, outperforming the reference garments in all effect categories. This superiority is primarily a consequence of avoiding garment production via reprinting and reassembly of the initial garment to extend its useful life.”
- Dr Greg Peters, LCA Researcher at Chalmers University of Technology

Another way to circumvent the impacts of fast fashion is to develop materials with considerably lower impacts during production, and which also avoid the barriers to recycling faced by conventional garments. Instead of hinder consumers from buying new, the act of acquiring a new garment could in fact be sustainable. The paper-based short life garments considered in this assessment show considerable impact savings when compare to the benchmark garment. Dr. Peters says,

“The paper-based garments benefit from the lower impacts of the material (fibre production, spinning and knitting) compared with conventional cotton, from their relatively light weight and also on account of the lower impacts in garment production and use.”

Archroma, a global leader in color and specialty chemicals, has presented an aniline-free* denim indigo dye at the recent Planet Textiles 2018 Conference in Vancouver, Canada. The brand new dye provides a non-toxic way to produce the traditional, iconic indigo blue that consumers associate with denim and jeans.
Currently, aniline impurities are an unavoidable element of producing indigo-dyed denim. Unlike other chemical impurities, aniline is locked into the indigo pigment during the dyeing process and therefore cannot be washed off the fabric.

Scientific testing has shown that aniline impurities are toxic to humans, causing skin allergies, damage to major organs and genetic defects, as well as being linked to cancer. Aniline is also toxic to aquatic life, which is an issue as two thirds of the 400 metric tons of aniline waste on an annual basis ends up in the environment as wastewater discharge. The toxic chemical is therefore starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers. “We have tested denim garments and found that aniline concentrations are frequently higher than expected,” says Alexander Wessels, CEO, Archroma. “This could put some manufacturers over the limits agreed on their RSLs.”

True to its commitment to take on innovation challenges, Archroma decided to take a closer look at the issue with its R&D experts, and developed an alternative system that is aniline free*.
“At Archroma, we continuously challenge the status quo in the deep belief that we can make our industry sustainable,” continues Alexander Wessels. “By removing a hazardous impurity from the denim supply chain, we aim to protect the workers who create denim, the consumers who wear denim, and the environment with cleaner waterways.” The Denisol® Pure Indigo 30 dye is the latest in a long line of sustainable innovations for denim started in 2009. That year, Archroma introduced its ‘Advanced Denim’ technology which uses up to 90% less water during the dyeing process. “Being not indigo but sulfur based, ‘Advanced Denim’ itself was an aniline free solution too!”, adds Alexander Wessels. For designers and brand owners who long for authentic indigo inspiration, the new Denisol® Pure Indigo 30 now also makes it possible to produce indigo-dyed denim without high levels aniline impurities. Archroma successfully tested Denisol® Pure Indigo 30 at Absolute Denim mill in Thailand. “During the testing everything performed exactly the same as it would with conventional indigo,” says Vichai Phromvanich, Board Member, Absolute Denim. “There was just one important difference: no aniline.”

“We’ve had an overwhelming positive reaction from the industry in sneak previews and during the launch at Planet Textiles,” continues Alexander Wessels. “As a responsible industry leader, we believe it’s important to actively look for eco-advanced solutions that are attractive and at the same time cost-efficient for clothing brands, retailers and end-consumers.”

Archroma will make the Denisol® Pure Indigo 30 dye in the most sustainable way as possible. The new dye will be produced in Archroma’s facility in Pakistan, a plant that made the headlines in 2012 for being what Archroma believed to be the industry’s first zero liquid discharge plant.

What Keeps Consumers Up at Night?

Climate change appears to be a bigger concern for consumers than recent media reports may have indicated. In the ground-breaking, global, quantitative consumer survey, “The Key to Confidence: Consumers and Textile Sustainability—Attitudes, Changing Behaviors, and Outlooks”, commissioned by the OEKO-TEX® Association in commemoration of its 25th Anniversary, climate change ranked third on a list of sixteen modern day worries on the minds of today’s consumers.

“The Key to Confidence” online study was conducted earlier this year with a worldwide sample of more than 11,000 clothing and home textile consumers. Designed and administered by global brand and sustainability research expert, Ellen Karp of Anerca International, the extensive study explored a broad assortment of consumer attitudes about textile sustainability including harmful substances, the industry’s environmental impact, and the social welfare of textile workers.

Prior to answering questions about clothing and home textiles in particular, consumers responded to several queries to gauge their attitudes about sustainability in general. To understand the relative importance of climate change, consumers were asked to pick the top five issues that worry them most from a list of sixteen political, economic, personal, and global problems. “Terrorism” ranked first with 49% of consumers listing it in their top 5, “illness and disease” was second with 42%, and “climate change” rated third with 41%. “My personal finances” came in fourth at 37%. “Opportunities for my children in the future” and “the political leadership in my country” tied for fifth with 31% each.

“Climate change has become a significant issue for consumers,” Karp concludes. “Erratic weather patterns, mounting scientific data, escalating political debate, and first-hand experience with environmental degradation combine to make climate change more of an immediate threat than people considered it to be just a decade ago.”

“For twenty-five years, OEKO-TEX® has helped reduce the use of harmful chemicals and increase sustainable manufacturing practices in the global textile supply chain,” says Anna Czerwinska, Head of Marketing and Communication at OEKO-TEX®. “Our certified clients are industry leaders in the production of compliant, high quality textiles that are tested for harmful substances and responsibly made with respect for the environment and employees. They will be well positioned to capitalize on the growing consumer demands for sustainable textile products.”
