Preparation, Analysis, and Characterization of Miura-ori Structure Woven Fabric

To produce textiles with geometric patterns and stable structure, the classic Miura-ori structure in the origami folding structure was selected. Through material selection and fabric structural design, the Miura-ori structure fabric was developed using a combination of elastic and inelastic weft yarns on automated jacquard looms. Miura-ori structure woven fabric Miura-45 and the regional fabrics Miura-M, Miura-V, and Miura-P forming the structure were successfully fabricated. Miura-45 exhibited well-defined creases and flat unfolded surfaces, with elastic weft shrinkage effectively forming the Miura-ori structure post-weaving. To further study the Miura-ori structure fabric and prove the stability of the structure, the mechanical properties and thermal–moisture performances of Miura-45 and fabrics in each regions were analyzed. The results showed that Miura-45 exhibited minimal tensile deformation ratio (0.2%), maximum stiffness in the warp direction (353 mN·cm on the front), and optimal compression resistance (compression ratio 16.1%), confirming structural stability. Furthermore, Miura-45 showed superior air permeability (69.4% improvement under the pressure difference of 200 Pa), moisture transmission (15.3% higher), and thermal resistance (0.105 m²·K/W) compared to Miura-P. Miura-ori woven textiles demonstrate remarkable structural integrity and scalability for industrial production. Their combination of geometric precision and enhanced performance suggests promising applications in technical textiles and smart material systems.
