Despite the fact that Pyrovatex is widely used as a commercial flame-retardant, the release of toxic formaldehyderemains a serious problem. Fluorine-based compounds, on the other hand, have been employed to impart hydrophobic textilesurfaces, although they are exceedingly costly and poisonous. Based on those difficulties, we describe a simple one-stepmethod for coating electrically conductive cotton-nickel (Cot-Ni) blend fabric providing flame-retardant and water-repellentcharacteristics. A nickel ribbon was firstly bent around a cotton yarn as a core, and then woven into an electrically conductiveCot-Ni blend fabric, which was created by weaving the cotton-nikel hybrid threads with regular cotton yarns. The conductivefabric was coated with a composite consisting of silicone rubber (RTV) and ammonium polyphosphate (APP). The strongbinding of RTV with both APP and cotton fibres increased the flame-retardant action of cotton, according to the findings. Asa result, varied concentrations of APP were used in the composite to show that only 100 g/l of APP combined with RTVimproved the fire-retardancy. Depending on the concentration of APP, distinct hierarchical morphologies appeared on thesurface of the coated Cot-Ni fabrics. RTV also improved the hydrophobic character of the blend surface. Measurements of airpermeability, surface roughness, and stiffness were used to investigate the comfort qualities of the coated Cot-Ni blends. Eventually, those multifunctional (Cot-Ni)/RTV-APP textiles might be used in a variety of applications, such as grain storagecontainers, car seat mats, and firefighters' uniforms.
