New Technology Protective Clothing Meets Emergency Rescue Protection Needs

Donghua University, in collaboration with Shenzhen Utopai Apparel Technology Co., Ltd., has made significant progress in the field of protective clothing through their joint project titled "Multifunctional Design R&D and Performance Evaluation of Protective Clothing." This initiative was awarded the 2013 "Textile Light" Science and Technology Second Prize. The project focused on developing multi-functional protective garments that offer a range of critical features, such as flame resistance, heat insulation, water resistance, breathability, and antibacterial properties. These innovations are particularly useful for emergency responders who face multiple hazards during rescue operations. Traditional protective clothing often relies on flame-retardant fibers, which provide limited protection and may lack comfort. In contrast, modern solutions like meta-aramid fibers offer intrinsic flame resistance due to their unique chemical structure. These materials resist burning, self-extinguish when the fire source is removed, and form a carbonized layer that insulates against heat without melting or dripping. However, these traditional options still have limitations in terms of functionality and user comfort. The project led by Li Jun from Donghua University's Department of Fashion Design and Engineering introduced a new theoretical model for functional design in protective clothing. It established concepts such as layered insulation and multiple protections, aiming to provide comprehensive safety against various threats. By combining thermal protection performance (TPP) with total heat loss (THL), the team designed advanced fabric systems. They also developed a two-step optimization technique to create composite fabrics with waterproof, breathable, anti-viral, and antibacterial properties. Additionally, they introduced a four-dimensional dynamic body structure design to enhance adaptability during work activities. In terms of evaluation, the project developed a comprehensive characterization technique to assess the physical, chemical, and ergonomic performance of protective fabrics. They created a thermal protection performance tester that simulates real-world conditions, revealing how multi-layer fabrics perform under stress. A high-temperature liquid scald protection evaluation device was also developed, contributing to the understanding of liquid permeation protection. The "Donghua Fireman" system, China’s first burning dummy, allows for realistic testing of protective gear, offering quantitative insights into burn severity and overall thermal protection performance. "Donghua Fireman" is a groundbreaking laboratory that simulates human body structures, accurately measuring heat flow in different postures and reporting burn data. Its adjustable joints mimic firefighter movements, helping researchers improve garment design based on Chinese body characteristics. This technology enables more precise and effective protective clothing development. Hu Zuming, director of the Chemical Fiber Research Institute at Donghua University, emphasized that fabric research and combustion tests are essential for creating safer protective equipment. By improving test methods, researchers can better understand how to protect individuals in dangerous environments like fires and battlefields. The project adopted a structured approach, with clear roles and responsibilities among all participants. Donghua University and Shenzhen Utopai worked closely, leveraging each other's strengths. The university provided research expertise, while the company brought practical experience, ensuring rapid application of new technologies in production. Through regular meetings and expert discussions, the team efficiently addressed challenges and accelerated the transformation of research into real-world products. The results of this project have already been widely applied in the production of flame-resistant, chemical, and general protective clothing, marking a major advancement in the field of personal protective equipment.
