▎ 摘 要
NOVELTY - Preparing graphene antibacterial yarn comprises (i) pouring prepared graphene oxide solution into immersion tank, turning on vibrator at bottom of immersion tank, and immersing yarn in immersion tank for preset time, at a specific squeeze rate, making yarn complete pad coating in solution, and passing through oven channel into semi-dried state, and (ii) adding photoinitiator to prepared cinnamaldehyde solution, stirring and mixing to obtain mixed solution, soaking graphene yarn in mixed solution, raising temperature and setting low-frequency ultrasonic vibration for preset time, and placing under certain intensity of ultraviolet light, collecting yarn and naturally cooling, drying and shaping in an oven channel, and then winding to obtain graphene antibacterial yarn. USE - The method is useful for preparing graphene antibacterial yarn. ADVANTAGE - The method is simple and convenient. The yarn: has antibacterial and thermal insulation, doubled antibacterial and anticorrosive ability, improved peculiar smell generated by long-term storage of yarn, and deodorizing effect; and is environmental-friendly, and not easy to wash out during storage and later use.
