In this second session of Ask the Innovators, join us Jan. 27th on the Green Chemistry Innovation Portal to discuss the science of greener alternatives to durable water repellents for textiles. For an introduction to the topic, see this article by Christiana Briddell. During our online discussion, you can ask innovators and researchers at Patagonia, Chemours, the Swedish Research Institute for Industrial Renewal and Sustainable Growth (Swerea), and the University of Leeds anything you would like to know about durable water repellent technology. Our participants have been recruited from different sectors and areas of expertise in order to provide a variety of perspectives on this topic.
The experts joining us for this session will be:
- Bob Buck, Chemours
Bob Buck works for The Chemours Company and has 28 years of experience in textiles and DWR finishes. The Chemours Company produces both short-chain fluorinated and renewably sourced non-fluorinated DWR products. Bob leads a multi-disciplinary program to understand the life-cycle sustainability of Chemours’ products. This work includes advocacy, global collaboration, communication and interaction with academic, regulatory, NGO and industrial scientists. He is a co-author of numerous peer-reviewed publications and book chapters.
- Matt Dwyer, Patagonia
Director of Materials Innovation
Matt Dwyer received his B.S. in Materials Science & Engineering from Lehigh University in 2006 and spent nearly 8 years at W.L. Gore & Associates developing ePTFE-based high performance technical fabrics. He now directs Materials Innovation at Patagonia, which is much more than sourcing fabrics from existing supply chains -- successful innovation in materials requires having the resources to understand and implement clean chemistries and technologies all the way up the supply chain, of which DWR is a critical component. DWR has been a constant theme in Matt's career, from early challenges in optimization, to managing the transition away from C8-based chemistries on technical fabrics, and investing and implementing future technologies in the Outdoor Industry.
- Stefan Posner, Swerea IVF
Stefan Posner is a polymer and textile chemist at Swerea IVF with over 30 years experience in researching chemicals in textiles and polymeric materials. He has collaborated with international companies, governments, and academia in several international projects over the years. Stefan has spent many years doing legal preparatory work on chemicals for UNEP Stockholm Convention, EU Commission and several national authorities and is deeply involved in research to substitute hazardous chemicals. His work has recently focused on highly fluorinated substances and flame retardants.
- Philippa Hill, University of Leeds
Philippa Hill is a Ph.D. researcher at the University of Leeds, UK, studying repellency in outdoor apparel, specifically consumer care and maintenance. Her research work includes laboratory-based and qualitative social methods, working alongside the outdoor industry. She is a keen mountaineer, which adds to her interest in repellent outdoor apparel and the end-use of the chemistry on fabric.
Ask the experts anything you like: How do durable water and stain repellents work? Why are conventional chemistries falling out of favor? What alternatives to perfluorinated chemicals are available? How can academia and industry collaborate to create next generation textile chemistry?
