Flame retardant cotton

Flame retardant cotton is cotton that has been treated to prevent or slow ignition by different treatments applied during the manufacturing process. Cotton is typically made flame-resistant by chemical applications of polymeric, nonpolymeric, and polymeric/nonpolymeric hybrids that are composed of one or more of the elements such as nitrogen, sodium, phosphorus, silicon, boron, or chlorine.[1]

Flame retardant cotton is often used in oven mitts, pot holders, and other heat-adjacent accessories.

Manufacturing

While non-organic fabrics are typically made flame-resistant by incorporating flame retardants into their matrices, surface modification is more convenient for organic fabrics like cotton.[2]

Use

Cotton fabrics have been frequently used worldwide because of their advantageous properties with regard to thermal insulation, biocompatibility and great moisture absorption and breathability performances. These advantages indicate potential applications of cotton fabrics in protective clothing and human health. However, natural cotton fabric is highly flammable and will rapidly burn out. This fatal drawback reveals a potential danger and limits the use of cotton fabrics. Therefore, treating cotton fabrics to obtain fire-resistant cotton fabrics is important.[3]

Firefighters, or those exposed to flames on a regular basis, rely on flame-retardant cotton for both protection and comfort. Typically, their undergarments beneath the heavier fire-resistant gear are made of flame-retardant cotton or another breathable, organic fabric that's been treated to resist ignition. [4]

Polymers containing nitrogen, sodium, and phosphorus atoms can work as materials for fire-resistant cellulosic textiles, such as cotton or rayon. Specifically, organic polymers can work as a flame-retardant due to the presence of one or all three types of these elements. These atoms can be in the original polymers, or they can be incorporated by chemical modification. [1]
