What fire-retardant treatments are used for acrylic fabric in public installations?

Acrylic fabric is widely used in public installations due to its durability and vibrant colors, but its flammability requires specialized treatments to meet safety standards. Common fire-retardant methods include chemical coatings, such as ammonium polyphosphate or brominated compounds, which inhibit flame spread. Another approach involves incorporating flame-resistant additives during fiber production. Public spaces often require fabrics to pass stringent tests like NFPA 701 or ASTM E84 to ensure compliance. Additionally, some acrylic fabrics are treated with intumescent coatings that expand when exposed to heat, creating a protective barrier. These treatments ensure acrylic textiles remain safe for use in theaters, museums, and transportation settings while maintaining aesthetic appeal. Regular re-treatment may be necessary for long-term fire resistance.
