NOVELTY - Modifying nylon 6 fibers involves dispersing conductive metal powder and organic-inorganic hybrid in graphene oxide dispersion liquid to obtain compound dispersion liquid. The compound dispersion liquid is mixed with caprolactam to obtain mixed liquid. The mixed liquid is subjected to ring opening and polymerization reaction, post-treatment and spinning. USE - Method for modifying nylon 6 fibers. ADVANTAGE - The method helps to improve the dispersion of inorganic components, metal fibers, and graphene in the polymer matrix. The inorganic component imparts the hybrid with better thermal stability, and modified product has high flame retardancy and high electrical conductivity with good comprehensive properties.
