Evaluation of Functionality and Mechanical Performance in Transformable Textile Systems Developed Through a Sustainable Design Approach

Abstract

In the context of sustainable product design, the ability of a single product to fulfill multiple usage functions is of critical importance in reducing resource consumption. In this study, a multifunctional transformable textile product was developed from PU-coated ripstop polyester fabric, which can be used as a raincoat, backpack, and seating mat. The performance of the product was evaluated through water resistance, tear strength, and load-bearing capacity tests. The results indicated that, although there were some statistical differences between usage modes, the mechanical performance was largely maintained. In backpack mode, the product demonstrated an average load-bearing capacity of 12.9 ± 0.3 kg, and no structural damage was observed during the tests. Furthermore, effective waterproof performance was achieved across all usage modes. The findings demonstrate that the developed transformable textile product maintains its functional and mechanical properties, making it suitable for sustainable and multifunctional use.
