“…viscose). With respect to untreated fibres, the temperatures of their first degradation step and of flame combustion of volatile products were found increased by 20 8C, while the temperature rise of Methyl red [190,191] Shielding of X/a-rays Barium sulphate [192] Super-paramagnetism Fe 3 O 4 [193] glowing combustion of the residue was higher than 40 8C. Similar results were collected by our group applying the same strategy to cotton, polyester and their blends [209]: indeed, the formation of a continuous silica film deposited on the fibres (regardless of the type) exerted a protective role towards their thermal degradation in air.…”

“…As far as textiles are concerned, sol-gel processes have been effectively utilized for providing them with multifunctional features; more specifically, great attention has been devoted to the development of "smart" textiles. These later can show super-hydrophobic properties [17][18][19], antimicrobial [20][21][22] or UV radiation protection [23][24][25], dye fastness [26,27], biomolecule immobilisation [28], anti-wrinkle finishing [29], sensor characteristics [30,31], and photocatalytic features [32,33].…”

Fabric flammability is a surface-confined phenomenon: in fact, the fabric surface represents the most critical region, through which the mass and heat transfers, responsible for fueling the flame, are controlled and exchanged with the surroundings. More specifically, the heat the fabric surface is exposed to is transferred to the bulk, from which volatile products of thermal degradation diffuse toward the surface and the gas phase, hence feeding the flame. As a consequence, the chemical and physical characteristics of the fabric surface considerably affect the ignition and combustion processes, as the surface influences the flux of combustible volatile products toward the gas phase. In this context, it is possible to significantly modify (and improve) the fire performance of textile materials by "simply" tailoring their surface: currently, one of the most effective approaches exploits the deposition of tailored coatings able to slow down the heat and mass transfer phenomena occurring during the fire stages. This paper reviews the current state of the art related to the design of inorganic, hybrid, or organic flame-retardant coatings suitable for the fire protection of different fabric substrates (particularly referring to cotton, polyester, and their blends). More specifically, the use of sol-gel and layer-by-layer (LbL) methods is thoroughly discussed; then, some recent examples of flame retardant coatings are presented, showing their potential advances and their current limitations.

State of the art and perspectives on chemicals and techniques which have been developed in textile finishing for conferring flame retardant properties to natural and synthetic fibres are discussed in this review. An overview on the mechanism of combustion and fire retardancy is reported as well as the chemistry of flame retardants action, the different available types and their uses. The chemistry of molecules used to improve fire retardancy is discussed along with their thermal stabilities and flame-retardant properties. Simplified assumptions about the gas and condensed phase processes of flaming combustion provide relationships between the chemical structure of polymers and fire behaviour, which can be used to design fire-resistant textile materials. Moreover, an overview of currently accepted test methods on textile fabrics to quantify burning behaviour is reported. Finally, as a consequence of increasing commercial demands in terms of costeffectiveness coupled with increasing concerns about the environmental and general toxicological character of flame retardant additives, some consideration is also given to both the novel approaches of the chemistry of antimony-free and halogenfree flame retardants and to attempts at increasing the efficiency of known chemistry to enhance char formation by intumescent action.
