Summary: A novel flame retardant containing high amounts of P and N elements was designed and grafted onto cotton fabric via P-O-C covalent bonds, showing improved flame retardancy and durability. The treated cotton exhibited lower peak heat release rate, total heat release, and initial decomposition temperatures, as well as increased carbon residue during combustion, indicating the formation of an expanded char layer. Various spectroscopic techniques confirmed the flame retardant mechanism, and the mechanical properties of the treated cotton remained suitable for use after treatment.

Summary: Efficient, durable, and breathable flame retardant cotton fabrics were successfully fabricated using a one-pot approach. The modified fabrics exhibited high fire resistance, self-extinguishing properties, and excellent washing durability. The surface hybrid network architectures formed by multiple covalent bonds and electrostatic assembly contributed to the significant reduction in heat release rate, total heat release, and total smoke release. This study provides a simple and feasible method for achieving high-efficiency and durable flame retardant cotton fabrics.

Summary: In this study, a formaldehyde-free flame retardant cotton fabric with ultra washing durability was prepared through covalent bonding and interface polymerization. The fabric showed excellent flame retardancy, even after 300 washing cycles. The interface polymerization between PEI and TMC stabilized the flame retardant coating and protected the fabric, leading to durable flame retardancy. This work opens up promising prospects for the fabrication of bio-safe durable flame retardant cotton fabrics.

Summary: Novel flame-retardant cotton fabrics were prepared by grafting phosphate and melamine, showcasing a phosphorous-nitrogen synergism that significantly improved fire resistance and durability. The fabrics exhibited high LOI, reduced THR and pHRR values, and could restore fire resistance after laundering cycles. Incorporation of phosphate and melamine facilitated the conversion of cellulose fibers to protective carbon layers, preventing decomposition into flammable gases.
