The invention provides a processing method of a healthcare antibacterial fabric with blended buckwheat hull and bamboo charcoal fiber. The processing method of the fabric comprises the following steps: (1) treating buckwheat hull and bamboo charcoal raw materials, namely, drying buckwheat hull, carbonizing, performing airflow milling, grading after airflow milling, and collecting granules of which the granularity is smaller than 0.35mu m for later use; drying phyllostachys heterocycla growing for more than or equal to 5 years, pre-carbonizing, carbonizing, performing airflow milling, grading after airflow milling, and collecting granules of which the granularity is smaller than 0.40mu m for later use; (2) spinning, namely, performing dry spinning on the buckwheat hull powder prepared in the step (1) and cellulose triacetate ester so as to obtain buckwheat hull cellulose acetate fiber; performing dry spinning on the bamboo charcoal powder prepared in the step (1) and cellulose triacetate ester so as to obtain bamboo charcoal cellulose acetate fiber; (3) weaving; (4) dyeing; (5) performing dyeing aftertreatment. The healthcare antibacterial fabric provided by the invention can not only promote and improve microcirculation of human bodies, but also has effects of clearing heat and removing fire, preventing flu, preserving heat and keeping warm as well as inhibiting bacteria and preventing mold.
