“…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].…”

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.

“…After pretreatment with KOH and subsequent carbonization, K and K 2 O were observed in the char, giving an indication that KOH had reacted with the carbonaceous components in PET. Only amorphous carbon was detected in PET H 3 PO 4 , indicating that the changes due to H 3 PO 4 mainly affected the organic components of PET [20].…”

“…The absorption peaks due to stretching vibration of C-H on the benzene ring and C=O on PET H 3 PO 4 were at 725 and 1705 cm −1 , respectively. The weak absorption peak at 969 cm −1 of the PET H 3 PO 4 spectrum was attributed to P-O-C groups, which were formed by the reaction between polyester and phosphoric acid [20].…”

In this study, a novel idea was proposed to convert the polyethylene terephthalate (PET) waste drinking-water bottles into activated carbon (AC) to use for waste cooking oil (WCO) and palm fatty acid distillate (PFAD) feasibility to convert into esters. The acidic and basic char were prepared by using the waste PET bottles. The physiochemical properties were determined by employing various analytical techniques, such as field emission scanning electron microscopy (FESEM), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), Brunauer–Emmett–Teller (BET) and temperature-programmed desorption – ammonia/carbon dioxide (TPD-NH3/CO2). The prepared PET H3PO4 and PET KOH showed the higher surface area, thus illustrating that the surface of both materials has enough space for impregnation of foreign precursors. The TPD-NH3 and TPD-CO2 results depicted that PET H3PO4 is found to have higher acidity, i.e., 18.17 mmolg−1, due to the attachment of phosponyl groups to it during pretreatment, whereas, in the case of PET KOH, the basicity increases to 13.49 mmolg−1. The conversion results show that prepared materials can be used as a support for an acidic and basic catalyst for the conversion of WCO and PFAD into green fuel.

“…[1][2][3][4] However, PET is extremely easy to ignite and numerous melt-dripping, moreover, melt-dripping of polymer results in the fire spreading quickly, and secondary damage and immediate empyrosis, which restricts its further application in confined environment area, especially in household textiles. A large number of studies have been dedicated to the antidripping of the PET, including the incorporation of inorganics flame retardants, [5] chemical modification, [6,7] and finishing. [8] In these methods, chemical modification by phosphorus-containing monomers is an effective way to improve the flame retardant of PET.…”

Polyester is widely used in household products because of its good mechanical properties and wears resistance, but polyester is easy to ignite and inclined to produce droplet, so its application range is limited. The cross‐linkable magnesium hydroxide nanoparticles were incorporated into flame‐retardant polyester, which enables the phosphorus‐containing copolyester with thermal cross‐linking and anti‐meltdrop properties. The nanoparticles were achieved by in situ polymerization and acted as a nucleating agent for improving the crystalline properties of the copolyester. Furthermore, the nanoparticles also enhanced anti‐meltdrop properties and reduced the heat and gas release during the combustion process of the copolyester. The maximum heat release rate and total smoke release reduced by 39.8% and 74.4% compared with pure polyester. Specifically, the combustion products of the nanoparticles and phosphorus flame retardant could act a barrier role by covering the carbon layer to isolate air and heat, thereby resulting in excellent anti‐meltdrop properties. The simple modification method reported here realizes the collaborative modification of flame retardant and anti‐meltdrop properties of phosphorous flame‐retardant copolyesters by thermal cross‐linking.
