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: This study presents a novel and facile approach for developing flame retardant wool fabrics by covalently grafting bio-based ammonium phytate onto wool fibers. The modified wool fabrics showed improved flame retardancy, increased tensile strength, and reduced smoke and heat release properties. The investigations confirmed the intumescent flame retardant mechanism for the APH modified wool 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: A high-efficiency durable flame retardant (THPO-P) was synthesized and chemically bonded to cotton fabric, significantly improving its flame retardancy and durability. The treated fabric exhibited excellent fire safety and durability, with significant reductions in total heat release and peak heat release rate values. The flame-retardant treatment process did degrade some physical properties of the cotton fabric.

Summary: In this study, a durable flame retardant cotton fabric (Cotton-APA/LNT) was successfully fabricated by covalently bonding ammonium phytate (APA) and lentinan (LNT). The Cotton-APA/LNT fabric exhibited high limiting oxygen index (LOI) value and self-extinguishing ability. After laundering cycles, the fabric still showed good flame retardancy and improved durability and breaking force.

Summary: Metal ions coordinated with biomass tannin and tartar emetic were used to prepare durable flame-retardant cotton fabrics. The Ca2+ and Zn2+ systems showed better flame retardant effects than Fe2+, Co2+, and Ni2+. Through tracking the catalytic carbonization process, the study provides insight into the durable flame-retardant mechanism of biomass TA-metal complexes.
