“…This behavior is probably due to its dimensional instability (leading to an inconstant exposed surface) but may also be related to the behavior of some very thin samples studied elsewhere. 12,20 Indeed, in these studies, the thinnest samples do not ignite in cone calorimeter test or TTI is longer.…”

“…First, the heat flux may not be fully absorbed. [9][10][11][12] Second, samples are prone to distort or to blow during heating. Therefore, the exposed surface is not constant and the measurements are not reliable anymore.…”

The flammability of nine polypropylene fabrics or sheets has been tested using cone calorimeter at various heat fluxes (25, 35, 50, and 75 kW/m 2) in order to assess the relevance of this fire test for thermally thin materials. The chosen procedure uses a grid and allows maintaining a constant exposed surface during the test, except for the lightest fabric. The structure of the knitted fabrics has a relatively small influence on the main flammability parameters. On the contrary, the area density of the sample (from 218 to 5729 g/m 2) impacts strongly the time to ignition, the peak of heat release rate, and the increase in heat release rate after ignition (fire growth rate). At a fixed heat flux, thicker is the sample, higher are the time to ignition and the peak of heat release rate and lower is the fire growth rate. Moreover, thick samples exhibit the highest sensitivity of peak of heat release rate and the lowest sensitivity of fire growth rate to heat flux. This study emphasizes the fact that a moderate change in weight may have a significant influence on cone calorimeter results, without any significance on real flammability.

“…Th e sample was fi rst pyrolyzed in nitrogen. Th e volatile products were then mixed with oxygen and burned in a combustion zone in order to measure the combustion heat of pyrolysis products [22]. Several fl ammability parameters were obtained, including the heat release rate (HRR), total heat release (THR), heat release capacity (HRC), the peak heat release rate (pHRR), temperature at maximum heat release rate (T max ) and char residue yield.…”

Bio-based fl ame-retardant agents and layer-by-layer assembly have attracted a great deal of attention in the fl ame-retardant fi elds of textiles, composites and polymeric materials. In this study, the electrostatic layer-by-layer assembly of chitosan and sodium phytate on silk fabric was carried out using a padding technique. The eff ects of the concentration and assembled bilayer of chitosan and sodium phytate on the weight gain, fl ammability, surface morphology, whiteness, stiff ness, lustre, tensile strength, and washing durability of silk fabric were studied, and the heat release, thermal stability and fl ame-retardant mechanism of the coated fabric were analysed. The results revealed that at 10 to 15 assembled bilayers, the coated fabrics exhibited high limiting oxygen indexes and passed the vertical burning test, and their good fl ame retardancy was maintained even after 15 washing cycles. Moreover, the coated fabrics exhibited a signifi cant decrease in peak the heat release rate and a strong charring ability at high temperatures. The chitosan and sodium phytate system acted as fl ame retardants in the condensed phase. Given the high weight gain of silk fabric, the layer-by-layer assembly of chitosan and sodium phytate using a padding technique was more applicable to the fl ame-retardant treatment of furnishing fabrics.

“…All samples modified with flame retardant-containing compositions have a lower Q max temperature and time at which Q max occurs, compared to unmodified fabric. This is a very positive effect since it facilitates dehydration, thereby the formation of char and reduction in the release of combustible gases [35]. In the next step, research was carried on fabrics modified with flame retardant compounds and additionally with fluorosilane (FS) as a hydrophobizing agent, i.e.…”
