Reactive P/S/N-containing synergistic flame retardant towards eco-friendly durable flame-retardant cotton fabric: Flame-retardant property, durability and mechanism

Year: 2022

Type: preprint

Abstract: Developing eco-friendly durable flame-retardant cotton fabric not only expands its application area, but also caters to the healthy and environmentally friendly concept of consumers. Herein, a reactive P/S/N-containing synergistic flame retardant (PSN) was synthesized to prepare eco-friendly durable flame-retardant cotton fabric through chemical modifying method. ATR-FTIR and NMR data confirmed its successful synthesis of PSN. TGA data showed that PSN triggered the earlier degradation, while facilitated the char formation at high temperature of cotton fabric. Whiteness and tensile data demonstrated that the high-temperature acidic processing environment deteriorated the whiteness and tensile strength of cotton fabric. Flame-retardant data revealed that PSN conferred outstanding flame retardancy, fire safety and durability to cotton fabric. For treated fabric with the add-on of 14.2%, it achieved an LOI value of 36.5% and extinguished spontaneously even after 50 laundering cycles. PHRR, THR and FGI values of treated fabric decreased sharply in comparison with those of the control fabric. TG-FTIR, SEM and XPS analyses confirmed that PSN exhibited high-efficiency flame-retardant behavior because of the synergy between P, S and N elements.
