Step 2: ball milling to obtain coffee grounds powder with a particle size of 0.5-2 microns, transfer it to a muffle furnace, adjust the temperature to 200-205°C, heat treat for 30-40 minutes, increase the temperature to 320-350°C at 20-25°C / min, heat treat for 60-80 minutes, then increase the temperature to 760-850°C at 10-15°C, heat treat for 2-4 hours, and ball mill the obtained material to obtain a finished coffee grounds-based activated carbon powder with an average particle size of 0.2-5 microns.

4. The anti-foot odor sports socks according to claim 1, characterized in that: The deodorizing viscose yarn is mainly prepared from the following raw materials: 100 parts of regenerated cellulose fiber spinning solution, 1.2-1.5 parts of surface-modified zeolite powder, 0.2-0.3 parts of zirconium carbide powder, and 8-10 parts of coffee grounds-based activated carbon powder.

5. The anti-foot odor sports socks according to claim 1, characterized in that: The deodorizing elastic yarn is twisted together with deodorizing viscose yarn and spandex yarn, and the quantity ratio of the deodorizing viscose yarn to the spandex yarn is controlled at 1: (3-4).

6. A method for preparing anti-foot odor sports socks according to any one of claims 1 to 5, characterized in that: The following steps are involved: Step 1, preparation of finished deodorizing viscose yarn; Step 2: Using an EJM178 spinning frame equipped with a concentrated siro spinning device to twist the deodorized viscose yarn to obtain a semi-finished deodorized viscose yarn; Step 3: soaking the semi-finished deodorized viscose yarn in a 5-8 g / L aqueous solution of a finishing agent TF-620 for 5-10 minutes, and drying to obtain a finished deodorized viscose yarn; Step 4: The finished deodorizing viscose yarn and the polyester yarn are twisted in two strands with a twist of 130-145 twists / 10 cm. The twisted yarn is oiled and dried to obtain the finished deodorizing elastic yarn. Step 5: the finished deodorizing elastic yarn is used as the face yarn, the deodorizing elastic yarn is used as the base yarn, and the finished socks are knitted with a plain needle.

7. The method for preparing anti-foot odor sports socks according to claim 6, characterized in that: The following steps are involved: The preparation of the finished deodorizing viscose yarn in step 1 comprises the following steps: S1.1, preparation of deodorizing composition and formulation of antibacterial composition; S1.2, add 1-2g of KH570 coupling agent and 2000-2400g of deionized water to 100 parts of the deodorant composition obtained, stir and mix well to obtain a deodorant composition hydrate; S1.3, add an accurately measured amount of antibacterial composition to the deodorizing composition hydrate and stir to mix evenly; S1.4, adding the mixture in S1.3 to the regenerated cellulose fiber spinning solution and mixing evenly to obtain a blended spinning solution; S1.

5. The spinning solution prepared in S1.4 is placed at room temperature of 20-25° C. and allowed to stand for at least 2 hours. The solution is then filtered, degassed, and aged to produce the finished deodorized viscose yarn according to the wet spinning process for spinning ordinary regenerated cellulose fibers.
