▎ 摘　　要

NOVELTY - A double-woven fabric is formed by weaving a graphene fiber yarn comprising 0.5-2 wt.% graphene material and a polypropylene fiber yarn having improved dyeability to a fiber yarn of polyester yarn, acrylic yarn and rayon yarn. The double-woven fabric comprises the graphene fiber yarn as an inner skin layer, and polypropylene fiber yarn as an outer skin layer. The graphene fiber yarn has a relatively high thermal conductivity compared to the outer skin layer when worn on the human body, and improves the blood circulation in the human body by 80-150% compared to normal fibers. The polypropylene fiber yarn has relatively high heat storage property compared to the inner skin layer. The outer skin layer comprises microporous particle materials having a particle size of 1-40 nm to improve blood circulation of the human body and skin comfort when worn by the human body. USE - Double-woven fabric is used for clothing. ADVANTAGE - The double-woven fabric has excellent thermal conductivity of body temperature, and improves the blood circulation of human body, and quickly discharges moisture and sweat.
