“…As depicted in Fig.8a, C 1s, N 1s, O 1s, F 1s, P 2p, Si 2s and Si 2p were found in the F-PEC coated fabric after burning. Speci cally, C 1s, P 2p and N 1s spectra also con rmed the carbonized structure including the formation of C = C (287.7 eV in C 1s), P-C (132.6 eV in P 2p), P-O-C (134.1 eV in P 2p), N = C (401.8 eV in N 1s), and N-C (399.8 eV in N 1s)(Qi et al 2023;Shi et al 2022).…”

Surface treatment is one of the most effective ways to impart ame retardancy to fabrics, woods, etc. Especially, water-soluble polyelectrolyte complex (PEC) coating deposition is one of the most environmentally benign and facile technologies. However, durability, especially washing durability, remains a huge challenge for almost all PEC coated materials. In an effort to keep the desirable ame retardancy of cotton against multiple washing, in this work, per uorodecyltrichlorosilane modi ed polyethylenimine (PEI) was prepared to coat onto the ammonium polyphosphate (APP) based PEC coating. The extra 2 wt% uorinated PEI have not only hardly lost the high LOI value (28.5%) of 10 wt% PEC-coated cotton, but also endowed this coated cotton with high water contact angle of 117 °. And the treated cotton displayed excellent antifouling performance to milk, coffee, honey, cola and ink. Notably, it still preserved self-extinguishing behavior on a vertical ame test, and high LOI value of 26.5%, after vigorously stirring in water at 40°C for 20 times. This facile and e cient method could provide a new strategy for durable ame-retardant cotton fabric against humid and pollutant conditions.

“…This is mainly due to the decomposition of AEPEA into phosphoric acid and poly phosphoric acid, which promotes the formation of a carbon layer on the surface of the fabric, isolates oxygen and heat, and further prevents combustion of the fabric. The TSP value of FRC-30 (0.58 m 2 ) is higher than that of control cotton (0.09 m 2 ), which is due to the formed carbon layer can prevent the further decomposition of cotton fabric (Qi et al 2023). The values of ame spread rate (FGR) is used to assess the re safety factor of the cotton fabric by Eq.…”

A novel halogen-free, formaldehyde-free, phosphorus-nitrogen-based flame retardant (FR), ammonium salt of erythritol phosphoric ester acid (AEPEA), was synthesized and coated onto cotton fabrics to increase the flame resistance of cotton. The structure of AEPEA was characterized by hydrogen nuclear magnetic resonance (1H NMR). Fourier-transform infrared(FTIR) and X-ray photoelectric spectrometer (XPS) results proved that AEPEA was chemical grafted on the cotton through P-O-C bond. The limiting oxygen index (LOI) of cotton treated with 300 g/L AEPEA reached 40.1% and the carbon length was 4.2 cm. After 50 laundering cycles (LCs), the LOI value could still reach 27.8%. Thermo-gravimetric (TG) and cone calorimetry test (CCT) were used to further investigate the flame retardancy and thermal stability of cotton fabric, and the results proved that the thermal stability of treated cotton was greatly improved. Scanning electron microscopy (SEM) showed that there was no significant change on the surface of treated cotton. The results of X-ray diffraction (XRD) showed that the crystalline morphology of cotton fabric was almost unchanged after flame-retardant finishing. Besides, the mechanical properties of the treated cotton only decreased slightly.
