The flame retardant (FR) staple fiber (1.4d to 15d solid fiber,  3d to 15d hollow conjugated fiber or Low melt fiber ) is made with adding non-halogen element of phosphorus system flame retardant and inorganic polymer flame retardant in the fiber polymerization process or Chips extrusion process.

Characteristics of flame retardant fiber:
1. Permanent flame retardant effect and contain no halogen element.
2. Non-toxic, low smoke volume.
3. Good flame retardant effect and thermal stability.

Application: it can be processed into non-woven fabrics, used in clothing and interior decoration materials.
