New smart flame retardant textile fabrics have been developed. Halloysite nanotubes have been used as flame retardant filler for textile fabrics. A facile and environmentally friendly vapor phase polymerization method was used for the polymerization of polypyrrole layer covering the surface of halloysite nanotubes and textile fabrics. The developed fabrics achieved interesting electrical conductivity properties. The electrical resistance of the developed one reached up to 0.21 kΩ compared with the 45,000 kΩ for blank textile fabrics, which represent the enhancement in the electrical conductivity of the new textile nanocomposites. The flame retardancy and thermal stability of the new textile nanocomposites were improved. The rate of burning was recorded as zero and 149.3 mm min À1 for developed textile nanocomposites and blank, respectively, achieving high class fire resistant fabrics. The electrical and flame retardancy properties were controlled by the preparation method. In addition, the mechanical properties of the developed fabrics were studied to achieve an enhancement in elongation. The blank and developed textiles were characterized by microscopic and spectroscopic techniques, thermal gravimetric analysis, mechanical testing and electrical resistivity measurements.

Noise pollution is rapidly increasing, posing a health risk, particularly in the low frequency range. Therefore, the development of cost-effective, environmentally friendly and efficient audible sound absorbing materials is a necessary and crucial process. To this end, smart multilayer sound absorber has been developed based on micro-perforated panels and Jute fabrics as renewable and eco-friendly sound-absorbing material. Different perforation shapes have been fabricated and used for micro-perforated panels and optimized. The sound absorption properties for the new developed sound-absorbing system were evaluated inside a two-microphone impedance tube achieving outstanding results. The developed sound-absorbing system achieved higher sound absorption properties recording more 70% at low frequencies range (<500 Hz), also achieved excellent sound absorption coefficient with broad bandwidth. Furthermore, the flammability properties of the used Jute fabrics were evaluated achieving flame retardancy property of 44 mm/min rate of burning and 20% LOI value. Additionally, the Jute fabrics mechanical and surface morphology properties were investigated. Hence, this study presents a smart, cost-effective, flame retardant and efficient absorption system suitable for noise control for a wide applications range.
