Phosphorus-based flame retardant fiber is three-dimensional crimp hollow polyester polymerization process, add the phosphorus-based flame retardants, prepared by co-condensation phosphorus flame retardant copolyester. Since the fire retardantcomponents were uniformly attached to the macromolecular chains, thus giving the product a permanent flame retardant properties.

Retardant hollow fiber through the British "BS5852" partⅡ standard tests by the French 1988 fire safety standards, testing agencies: Hong Kong Standards and Testing Centre.

BST-FRPET flame retardant polyester fiber can be used in interior decoration, bedding, clothing, car decoration and industrial materials.

Retardant dimensional crimp hollow fiber: 6.67dtex × 64mm 14.44dtex × 60mm
