Typha Fluff as a Sustainable Thermal Filling Material: A Comparative Study with Down and Polyester Fibre

To explore the feasibility of using Typha fluff as a filling material in textiles, this study conducted a systematic investigation of its performance as a sustainable alternative. Comparative tests were performed on Typha fluff, down, and polyester fibre—three commonly used filling materials—evaluating their fill power, compression resilience, thermal resistance, downproof performance, moisture regain, and antibacterial activity. The results indicate that although Typha fluff exhibits slightly lower fill power and thermal insulation than white duck down, it demonstrates notable advantages in resilience, downproof performance, antibacterial potential, and renewability. These combined merits highlight its potential as an eco‑friendly thermal filling material. This work provides both a theoretical foundation and experimental evidence to support the green application of natural plant fibres in textiles.
