“…In the past several decades, polyester textile has been widely applied to garment, upholstery, and decoration, etc. [1,2], because of its excellent properties, such as low cost, being resistant to chemicals, dimensional stability, and good physical features [3][4][5][6][7][8]. However, polyester textile is flammable and it will melt dripping during combustion, which caused potential fire risks to people's lives and property [9,10].…”

“…Treating polyester textile is a feasible method for obtaining flame-retardant textile due to its easy processing way. The treating methods include photo-induced grafting reactions [35], oxygen plasma treatment [36], layerby-layer (LbL) assembly [37][38][39], dyeing-like process [40], or sol-gel process [3]; traditional coatings by means of spray-, brush-, or roller techniques [41] and so on. More importantly, a simple and efficient treatment method can reduce the production cost and greatly save manual labour and material resources.…”

A flame retardant aluminum 2-carboxyethyl-phenyl-phosphinate (CPA-Al) was synthesized through the salification reaction. The molecular structure of CPA-Al and thermal stability were characterized by solid nuclear magnetic resonance, Fourier transform infrared spectroscopy, and thermogravimetric analysis. Subsequently, CPA-Al mixed in polyurethane was coated on polyester textile to obtain flame-retardant samples. The addition of 14.7 wt.% CPA-Al in textile sample can bring a limited oxygen index (LOI) value of 24.5%, 0 s after flame time, and the vertical burning B1 rating. Meanwhile, the incorporated CPA-Al reduced the peak heat release rate, total heat release, average effective heat of combustion, and increased the charring capacity of polyester textiles in contrast to the samples without CPA-Al. CPA-Al exerted not only its flame inhibition effect in gas phase, but also the charring and barrier effect in the condensed phase. Besides, with an increasing CPA-Al ratio in polyester textile, the contact angle gradually decreased from 123.6° to 75.6°, indicating that the surficial property of coating from hydrophobic to hydrophilic, thereby increasing the moisture permeability of polyester textile.

“…Poly(ethylene terephthalate) (PET) is a semicrystalline thermoplastic polymer which is widely used for producing high performance engineering plastics, clothing, and decorative materials due to its excellent mechanical performance, dimensional and chemical stability as well as low cost . However, high flammability is a main drawback of PET . As halogen‐containing especially bromine containing compounds which were once effective flame retardants for PET have being forbidden because of environmental issue, more and more researchers have focused on exploring halogen‐free flame retardants for PET .…”

A novel flame retardant [9,10-Dihydro-9-oxa-10-phosphaphenanthrene-10-oxideô triphosphazene (DOPO-TPN)] based on phosphaphenanthrene and cyclotriphosphazene was synthesized and used to improve the flame retardancy of poly(ethylene terephthalate) (PET). The structure of DOPO-TPN was characterized by nuclear magnetic resonance, Fourier transform infrared spectroscope (FTIR), and elemental analysis. PET/DOPO-TPN composites with different amount of DOPO-TPN were prepared and the flame retardancy was determined by limiting oxygen index (LOI) and vertical burning test (UL-94). With the incorporation of 5 wt % DOPO-TPN, the composite achieved a LOI value of 34% and UL-94 V-0 rating. The thermal properties of the PET/DOPO-TPN composites were investigated by thermogravimetric analysis. The flame retardant mechanism was investigated by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), FTIR, and scanning electron microscopy (SEM). The Py-GC/MS results showed that DOPO based fragments would exist in the gas phase during the pyrolysis of PET/DOPO-TPN composites which demonstrated that DOPO-TPN could act through gas-phase action to exert flame retardant effect. The results of FTIR and SEM demonstrated that DOPO-TPN could promote the formation of compact and intact char residues to inhibit the heat and combustible gas transmission in condensed phase.

“…As far as textile applications are considered, usually the sol-gel technique has been proposed for conferring new functional properties to fabrics, such as antimicrobial or UV radiation protection [3], dye fastness [4], anti-wrinkle fi nish [5] and hydrophobicity [6]. With the goal of improving fl ame resistance of fabrics, in the last years, textile fi nishing by sol-gel method has been systematically studied [7][8][9][10][11][12][13]. Th e treatment of textile materials with hydrolysed metal alkoxide solutions is an excellent tool to convey new properties to polymer surfaces, particularly if organic components, like phosphorous-based chemicals, are incorporated into the formulation [9].…”

This work investigates the use of organic-inorganic sol-gel coatings based on silica and phosphorous compounds for providing cotton fabrics with fl ame retardant features. To this aim, diethylphosphatoethyltriethoxysilane precursor was employed for the synthesis of several sols in combination with diff erent chemical additives. Sols were reacted with azo-based compounds and repeatedly applied onto the cellulosic substrate in a multilayer assembly, aiming at assessing the eff ect of the concurrent presence of Si, P and N on the overall fi re behaviour of the fabric. In order to evaluate the fl ame retardancy of treated cellulosic fabrics, fl ammability tests were carried out. The obtained results showed that the phosphorus-silica coating is able to promote the formation of a stable char that acts as insulator barrier. Finally, an additive P-N eff ect of the ceramic oxide coating in terms of increased residue and decreased heat release rate and total burning time was observed in cone calorimetry tests. Keywords: thermal stability, cellulosic fabric, sol-gel, diethylphosphatoethyltriethoxysilane, hybrid material Si, P in N vpliva Izvleček V prispevku je raziskana uporaba organsko-anorganskih premazov sol-gel na podlagi silicijevih in fosforjevih spojin, s katerimi bi bombažnim tkaninam zagotovili odpornost proti gorenju.
