“…Molten polyester furnishes additional fuel to the gas phase and, as the polymer temperature is raised, heat is produced from the combustion of cotton decomposition products. Additional fuel increases the vigor of gas phase oxidation [58,59]. By reducing the ratio of cotton in cotton/polyester blends, the total heat release (THR) values, as well as the char yield, increase [60,61].…”

A detailed review of recent developments of layer-by-layer (LbL) deposition as a promising approach to reduce flammability of the most widely used fibers (cotton, polyester, polyamide and their blends) is presented. LbL deposition is an emerging green technology, showing numerous advantages over current commercially available finishing processes due to the use of water as a solvent for a variety of active substances. For flame-retardant (FR) purposes, different ingredients are able to build oppositely charged layers at very low concentrations in water (e.g., small organic molecules and macromolecules from renewable sources, inorganic compounds, metallic or oxide colloids, etc.). Since the layers on a textile substrate are bonded with pH and ion-sensitive electrostatic forces, the greatest technological drawback of LbL deposition for FR finishing is its non-resistance to washing cycles. Several possibilities of laundering durability improvements by different pre-treatments, as well as post-treatments to form covalent bonds between the layers, are presented in this review.

“…Phosphorous compounds (in CO/PES samples) influence the reactions taking place in the condensed (solid) phase. The flame retardant chemical is converted to phosphoric acid by thermal decay which extracts water from the pyrolysing polymer causing it to char (to produce a carbonaceous protective layer) [57].This process allows the decomposition of the polymer and reduces the amount and type of fuel precursor of volatiles. The presence of phosphorus in the formulation increase the fire resistance, LOI value and cause char formation.…”

In this study; licorice root, which is a sustainable natural material with a low environmental waste load, is used as an alternative fire retardant (FR) material. Flammable retardancy properties of 100% cotton and 50% cotton-50% polyester blended woven fabrics were researched by using licorice root and commercial organic phosphorus-nitrogen and phosphorus including compounds. Flame retardancy and thermal decay behaviour of the cotton and cotton/polyester blended fabric samples were qualified by the vertical burning test, limiting oxygen index (LOI), thermogravimetric analysis (TGA) and scanning electron microscope (SEM). The findings revealed that licorice root extracts enhanced the thermal behavior of the cotton and cotton/polyester blended fabrics after padding and coating processes. The practices increased the amount of oxygen demand for combustion in the environment and besides they did not change the morphological properties of the fabric samples. As a result, the usage of licorice root extracts considerably improved the fabric’s flammability under test.

“…When a polyester/cotton blend fabric is exposed to fire, the melting polyester can be retained by scaffold of cotton char, thus providing additional fuel for cotton's gas‐phase combustion when its degradation temperature zone (greater than 380°C) is reached . Such “scaffolding effect” makes the combustion of polyester/cotton blend fabrics more intense . It was found that polyester/cotton blends were more flammable than 100% polyester .…”

Summary Blend fabrics of cotton and polyester are widely used in apparel, but high flammability becomes a major obstacle for applications of those fabrics in fire protective clothing. The objective of this research was to investigate the flame retardant finishing of a 50/50 polyester/cotton blend fabric. It was discovered previously that N,N′‐dimethyloldihydroxyethyleneurea (DMDHEU) was able to bond a hydroxy‐functional organophosphorus oligomer (HFPO) onto 50/50 nylon/cotton blend fabrics. In this research, the HFPO/DMDHEU system was applied to a 50/50 polyester/cotton twill fabric. The polyester/cotton fabric treated with 36% HFPO and 10% DMDHEU achieved char length of 165 mm after 20 laundering cycles. The laundering durability of the treated fabric was attributed to the formation of polymeric cross‐linked networks. The HFPO/DMDHEU system significantly reduced peak heat release rate (PHRR) of cotton on the treated polyester/cotton blend fabric, but its effects on polyester were marginal. HFPO/DMDHEU reduced PHRR of both nylon and cotton on the treated nylon/cotton fabric. It was also discovered that the nitrogen of DMDHEU was synergistic to enhance the flame retardant performance of HFPO on the polyester/cotton fabric.
