NOVELTY - Treating functional fiber involves adding 18-22 g / square meter tourmaline powder to fiber pulp under stirring to obtain tourmaline treated fiber. The obtained tourmaline treated fiber is added and mixed with 0.8-1.2 mg / square meter graphene under stirring to obtain pre-treated fiber. The obtained pre-treated fiber is added and mixed with 8-12 g / square meter metal complex under stirring to obtain the desired product. USE - Method for treating functional fiber (claimed). ADVANTAGE - The method enables to treat functional fiber, which is capable of transmitting far infrared rays, negative ions, has magnetic therapy effect, antibacterial function, good toughness, tensile strength, durable, and convenient and is good for health.
