“…It not only serves as a clothing material but also finds utility in various daily necessities, thus playing a crucial role in the textile industry. However, cotton fiber has a limiting oxygen index (LOI) of only 18.0%, making it highly susceptible to ignition [4,5]. Once ignited, cotton fabrics quickly spread flames and pose a significant fire hazard.…”

“…Taking the example of flame-retardant cotton fabrics, the environmentally friendly halogen-free flame-retardant systems used at present are primarily based on either a single phosphorus-based flame retardant [12,16] or a synergistic system that combines multiple elements of phosphorus, nitrogen, and silicon [17]. Exemplary representatives include phosphonates, phosphorus/nitrogen-containing siloxanes [18], phosphazenes [5,19], Proban ® , and Pyrovatex ® [20,21] flame-retardant systems. In recent years, bio-based flame retardants [4] have gained popularity due to their non-toxic characteristics, the wide availability of sources of their raw materials, their biodegradability, and their ability to meet safety requirements in a sustainable manner [22,23].…”

Interest in the development of eco-friendly, sustainable, and convenient bio-based coatings to enhance flame retardancy and antibacterial properties in cotton fabrics is growing. In this work, chitosan was protonated at its amino groups using a method with a high atom economy using an equimolar amount of amino trimethylene phosphonic acid (ATMP), resulting in the fabrication of a single-component chitosan-based multifunctional coating (ATMP-CS), thereby avoiding any additional neutralization or purification steps. Cotton fabrics coated with various loads of ATMP-CS were prepared through a padding–drying–curing process. The morphology, thermal stability, mechanical properties, antibacterial properties, flame-retardant behavior, and flame-retardant mechanism of these fabrics were investigated. The coating exhibited excellent film-forming properties, and it imparted a uniform protective layer onto the surfaces of the cotton fabrics. When the load capacity reached 11.5%, the coated fabrics achieved a limiting oxygen index of 29.7% and successfully passed the VFT test. Moreover, the ATMP-CS coating demonstrated antibacterial rates against Escherichia coli and Staphylococcus aureus reaching 95.1% and 99.9%, respectively. This work presents a straightforward and gentle approach to fabricating colorless, environmentally friendly, and highly efficient fabric coatings that have potential applications in promoting the use of bio-based materials.
