“…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.

In the current study, diatomite-and polyvinyl alcohol (PVA)-modified nonwoven fabric was applied in membrane bioreactor (MBR) for wastewater reclamation. The characteristics of the modified nonwoven were elaborated via water contact angle, scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy measurements. It showed that the hydrophilicity of nonwoven was enhanced, and water contact angle was decreased from 112.71˚to 53.83˚. SEM images show that the nonwoven fibers are uniformly covered with PVA, and diatomite deposited on nonwoven fabrics is glued by PVA polymer. The performance of modified nonwoven was evaluated in MBR system at a flux of 6.2-16.5 L/m 2 h. Results showed that the anti-fouling property of modified nonwoven membrane was enhanced, and the effluent qualities could meet the requirements for water reclamation.

[17][18][19][20][21][22] However, the comonomers, especially phosphorus-containing comonomers, have relative high molecular weight and bulk. In other words, the steric hindrance effect of these comonomers is unfavorable for polymerization, and results in difficult copolymerization.…”

Summary Ultraviolet‐induced photografting polymerization combined with surface modification was developed to prepare durable flame retardant polyacrylonitrile (PAN) fabric. First, acrylic acid (AA) was grafted onto PAN fabric (PAN‐g‐PAA) through ultraviolet‐induced photograft polymerization. Then, PAN‐g‐PAA was modified sequentially by acylation, ammonization, and phosphorylation to obtain acylated PAN‐g‐PAA, ammoniated Cl‐PAN‐g‐PAA, and fire retardant PAN fabric, respectively. The influence of grafting time, concentration of acrylic acid, and initiator on the grafting percentage was studied in detail. Fourier transform infrared spectrometer, X‐ray diffraction, and scanning electron microscopy confirm the successful grafting of AA. The thermal properties of the fabrics were investigated by thermogravimetric analysis and differential scanning calorimetry. Thermal analysis indicates that FR‐PAN has good thermal stability at higher temperature and the char residue is about 41 wt% at 800°C. The limiting oxygen index value of the fire retardant fabrics can achieve 28.1 vol% and is still 27.3 vol% after 20 cycles washing, showing good durability.
