Beschreibung
Zusammenfassung:	The invention relates to the technical field of textile material, and solves the problem that 70% of flame-retarding agents in nylon 6 products in the present market are halogen flame retarding agents. The invention provides a preparation method of flame-retarding nylon 6 resin and uses thereof in flame-retarding nylon 6 flat filaments. A flame-retarding agent is added during in-situ polymerization of caprolactam monomers. The preparation method is simple; a halogen-free flame-retarding in-situ polymerization and modification method is used to enable the flame-retarding agent to uniformly disperse in nylon matrix and without aggregation; the flame-retarding effect is durable and mechanical performance is good and stable.
