ZHONGJIN FIBER Flame Retardant Fiber is a high-performance modified polyester staple fiber developed with halogen-free phosphorus-based flame retardant technology,ensuring safe and eco-friendly fire resistance without releasing toxic halogen gas during combustion. We supply two mainstream specifications: 1.5D×38MM and 2.5D×51MM,meeting diverse textile manufacturing and safety material demands. The fiber adopts intrinsic copolymerization flame retardant craft,integrating fire retardant ingredients into the molecular chain instead of simple surface coating,so its self-extinguishing performance will not fade after repeated washing and long-term use. It features excellent limiting oxygen index,stable vertical combustion performance,and no molten droplets when exposed to open flame,fully complying with international safety standards such as BS 5852,TB 117 and EN 45545. With uniform fineness,stable crimp and good spinnability,it can be blended with cotton,wool and conventional polyester fibers seamlessly. Widely applied in fireproof curtains,mattress filling,automotive interior fabrics,industrial protective clothing and public facility decorative textiles,this flame retardant fiber effectively delays flame spread and creates safer living and working environments. Strict quality control is implemented in every production procedure to guarantee batch stability,physical consistency and reliable fireproof performance for global textile and safety product manufacturers.
