▎ 摘　　要

NOVELTY - Master batch composition comprises a graphene oxide dispersion. USE - The master batch composition is used for producing graphene polyamide yarn. ADVANTAGE - The composition emits far-infrared rays, and has antibacterial performance, lubricity, UV blocking, electrical conductivity, heat dissipation, scratch resistance, abrasion resistance and tensile strength. The polyamide yarn has improved mechanical properties, such as flexural strength and flexural modulus. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene polyamide yarn comprising the master batch composition.
