▎ 摘　　要

NOVELTY - Graphene oxide-containing polyester yarns comprise 100 pts. wt. polyester, and 0.05-0.2 pt. wt. graphene oxide masterbatch composition comprising 99-99.9 wt.% polyester and 0.1-1 wt.% graphene oxide dispersion. The graphene oxide dispersion comprises 100 pts. wt. ionized water, 0.1-1 pt. wt. graphene, 0.07-0.7 pt. wt. neutralizer and 0.05-0.5 pt. wt. dispersant. USE - Graphene oxide-containing polyester yarns are used for forming textile product. The graphene oxide can also be used for forming ultra-lightweight and high-strength functional composite. ADVANTAGE - The graphene oxide-containing polyester yarns not only emit far-infrared rays, but also has improved antibacterial performance, lubricity, ultraviolet blocking property, electroconductivity, heat dissipation property, scratch resistance, abrasion resistance, mechanical property including tensile strength, flexural strength and flexural modulus, and function of inhibiting growth of bacteria harmful to the human body.
