NOVELTY - Preparing fiber involves mixing icariin modified graphene and deionized water in mass ratio of (0.5-1.5): (10-15) and performing ultrasonic treatment for 10-30 minutes to obtain icarrin modified graphene dispersion. The icarrin-modified graphene dispersion and menthol/chitosan spinning solution are mixed mass ratio (1-3):(4-8) and ultrasonic treatment is performed for 30-60 minutes, and finally wet spinning is performed to obtain the product. USE - Method for preparing fiber for graphene far-infrared magnetic therapy knee pads (claimed). ADVANTAGE - The method enables to prepare fiber, which has strong mechanical properties, good electrical conductivity and thermal uniformity, good antibacterial and anti-acarid effect, and promotes drug absorption and bone growth.
