A disclosed manufacturing method for negative-ion cellulosome comprises: step 1, selecting a base material, wherein the base material is a chemical fiber or cotton fiber material; step 2, preparing a nanometer tourmalinite slurry, specifically dissolving tourmalinite in water, wherein the weight ratio of tourmalinite to water is 3:5; step 3, injecting the prepared nanometer tourmalinite slurry into the base material by spraying; and step 4, drying the base material subjected to spraying injection to obtain the negative-ion cellulosome. In the step 3, the nanometer tourmalinite slurry is uniformly injected into the base material through spraying. In the step 4, air drying is employed and the drying temperature is 30-50 DEG C. The negative-ion cellulosome comprises a cellulosome body prepared from the chemical fiber or cotton fiber material, and the cellulosome body is inside provided with the nanometer tourmalinite. The beneficial effects comprise that the manufacturing method is practical, the production cost is low, the usage is convenient, and the manufactured negative-ion cellulosome is capable of effectively improving air environment around people, such as air environment in a car.
