On 25 March, the School of Fashion and Textiles at The Hong Kong Polytechnic University (PolyU), led by Prof. Fei Bin of the ESG Research and Sustainable Fashion Hub, hosted the Symposium of Sustainable Fashion and Materials. The event brought together over 100 attendees from academia and industry to address environmental challenges, showcasing recent research and technologies aimed at reducing ecological footprint while promoting circularity and safety.
The symposium began with a warm welcoming speech by Prof. Joanne Yip, the Associate Dean of the School of Fashion and Textiles at PolyU, emphasizing the importance of collaboration, inspiration, and innovation in forging new paths toward sustainability.
Dr. Yao Lei from The Hong Kong Research Institute of Textiles and Apparel (HKRITA) followed with a presentation on “Creative Solutions for Microplastics”. She introduced the new ISO 4484-2:2023 framework for quantifying microfiber release and her team’s bio-enzymatic method to digest microplastics in wastewater. While time-intensive, this approach highlighted the necessity of hybrid strategies, including stricter regulations, material innovation, and consumer education.
Mr. Yang Zhenggao, Vice Chairman of Polyrocks Chemical Co. Ltd, delivered a presentation on “Key Technology & Applications of Advanced Flame-retardant Materials”. He showcased innovative, non-toxic flame-retardant materials designed for plastics and emphasized their application in creating durable, fire-resistant textiles. This approach not only enhances safety but also contributes to waste reduction by promoting sustainability.
Prof. Yang Jinglei from The Hong Kong University of Science and Technology (HKUST) presented on “Microencapsulation of Fire Extinguisher Chemicals and Applications”. He introduced microencapsulated fire-extinguishing chemicals, utilizing ozone-safe perfluoro compounds (PFMP). This innovative approach allows for heat-responsive safety applications in flexible fabrics, such as athleisure wear.
Prof. Hu Yuan from the State Key Laboratory of Fire Science and the University of Science and Technology of China (USTC) delivered a presentation titled “Design Principles & Techniques of Polymer Fire Safety”. He elaborated on key principles in polymer design that achieve a balance between fire resistance and recyclability. Prof. Yuan emphasized the importance of developing materials that ensure user safety while decomposing responsibly, highlighting sustainability as a critical factor.
Lastly, Prof. Fei Bin presented on “Functional and Safety Composite Fibers with Green Advantages”. He showcased upcycled composite fibers, such as recycled polyester for cooling fabrics, elastomers for X-ray shielding textiles, and silk scraps repurposed for luminescent wearable technology – proving that waste can drive innovation.
The symposium underscored sustainability as a multidisciplinary effort. The panel moderated by Prof. Fei reinforced the need for traceable supply chains and youth engagement – announcing scholarships for sustainable fashion research. Discussions aligned with the event’s four pillars: advancing research, bridging industry-academia gaps, shaping ESG policies, and nurturing eco-entrepreneurs.
Speakers agreed on the inseparable link between durability and circularity. Flame-retardant innovations extend garment lifespans, while upcycling transforms waste into high-value products. Challenges, such as scaling bio-enzymatic solutions for microplastics, underscored the importance of collaboration among scientists, brands, and regulators. By merging cutting-edge science, ethical practices, and consumer awareness, the symposium charted a vision for a fashion industry that prioritizes safety, longevity, and environmental stewardship. Sustainability is not a limitation – it is a driving force for progress and transformation.
