“…Considering the residual masses obtained after heating the flax fibres up to 500 C, it can be noticed that the highest amount (47%) of residual char belonged to the PSil-treated fibres. These observations can be attributed to the well-known synergistic effect of P and Si atoms [27,28]. Based on the observed significant char promoting effect of PSil, advantageous influence was expected on the flame retardant properties of PSil-treated fibres and their composites as well.…”

Fully biodegradable composites were developed, possessing prominent mechanical performance and reduced flammability at the same time. The manufactured composites consisted of PLA/TPS biopolymer *Corresponding author: tel: +36 1-463-3654, e-mail: gmarosi@mail.bme.hu, address: Budafoki út 8, Budapest, 1111, Hungary matrices reinforced with chopped flax fibres. The flammability of the prepared biocomposites was reduced by a newly synthesized multifunctional additive system. Glycerol phosphate (GP), a plasticizer of starch with flame retardant potential, and a novel phosphorous-silane (PSil), applied as a surface treating agent of the reinforcing biofibres, were successfully combined in order to reduce the flammability of the prepared biocomposites. Owing to the beneficial effect of the applied multifunctional additive system, a loading of as low as 10 wt% of ammonium polyphosphate (APP) proved to be sufficient to provide prominent levels of flame retardancy to the composites, i.e. V-0 rating according to UL94, 33 vol% LOI and a 40% reduction of heat emission were achieved. Furthermore, the combined application of the surface treated reinforcing flax fibres and plasticizer in the biodegradable, flame retarded biocomposites resulted in well-balanced strength and stiffness.

“…DPTES was first combined with APTES or APTES and a melamine-based resin (M) [47]: this combination gave rise to a significant increase of char yields, as assessed by thermogravimetric analyses in air (42 and 38 wt % for APTES/DPTES-and APTES/DPTES/MF-treated samples, respectively). Then, the N-source was replaced with N,N,N',N',N",N"-hexakis-methoxymethyl- [1,3,5] triazine-2,4,6-triamine (MF) and the relative ratios of DPTES and MF were optimized [48].…”

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.

“…These films have shown enhanced flame retardancy properties (Cireli et al, 2007). Similarly, Brancatelli et al have very recently exploited the synergistic effect of silica (derived from sol-gel processes) and phosphorus to enhance the thermal stability and flame retardancy of cotton fabrics (Brancatelli, Colleoni, Massafra, & Rosace, 2011).…”
