Flame-retardant and Anti-melt-drop Dope-dyed Polyamide 6 Fiber

2025-03-31News 440

Preparative technique

The composite phosphorus-silicon flame retardant and pigment of

the “organic-inorganic hybrid halogen-free synergistic flame retardant

System” and specific polymers are blended and modified in a certain

ratio to prepare flame-retardant chips, which are then used to

prepare the fiber by melt spinning and multi-stage drafting processing

technology.

Q: Flame-retardant and anti-melt-drop dope-dyed polyamide 6 fibers are

widely applied in civil and industrial applications, and what important role does it play in case of fire?

A: As a wear-resistant fiber material with flame-retardant properties, it plays an important flame-retardant role and protective role in the fields of ropes, aircraft interiors, high-speed railroad interiors, military equipment and personal protection.Thanks to the adoption of advanced halogen-free, sulfur-free R & D design and high-temperature micro-crosslinking synergistic system, the fabric achieves slow

melting without dripping when burning, greatly reducing the risk of burns and other secondary injuries caused by fire to the human body, and effectively slowing down the fire.
