Development of Thermal Protection Sacks in Extreme Winter Conditions

Textile Engineering

This study explores the development of thermally insulated sacks made from recycled polyester and copper-wrapped polyester blends to enhance warmth in extreme winter conditions for both children and adults. The integration of post-consumer recycled polyester (rPET) and thermally conductive copper fibers offers a sustainable and effective textile solution. Copper contributes superior thermal conductivity and antimicrobial properties, while rPET supports environmental objectives by reducing plastic waste. This work investigates the material properties, blending techniques, thermal performance, and sustainability aspects of these hybrid textiles. The practical utility of these sacks across sectors such as humanitarian aid, defense, and outdoor activities is also examined. Key challenges, including compatibility between components and cost constraints, are addressed, along with potential pathways for technological advancements in smart textile integration. The findings underscore the potential of copper-wrapped polyester/rPET sacks as an innovative and eco-friendly solution for cold-weather protection.
