Systematic research shows that traditional Dai costumes have unique aesthetics but poor antibacterial properties in hot and humid environments, and there is still a lack of antibacterial research on their fabrics. This study used kapok fibre, silver fibre, viscose fibre, and polyester fibre. It used 18tex blended yarn (m (kapok fibre)∶m (silver fibre)∶m (viscose)∶m (polyester)=20∶10∶35∶35) blending technology to test the antibacterial activity of the fabric according to the national standard (China) GB/T 20944.1-2007 (agar diffusion plate method). The fabric formed antibacterial circles of 2.0mm and 2.9mm against Staphylococcus aureus and Escherichia coli and changed the original fabric's poor elasticity, poor wrinkle resistance and wear resistance, and itchy feeling. The innovative integration of Dai costume colours and patterns into fabric design provides scientific support for Dai costume design while exploring new paths for integrating traditional costumes and modern technology, laying a solid foundation for cultural inheritance and development.
