A method for producing a dye-free medical towel from a dye-free cotton material, comprising: preparing the dye-free cotton material for processing by: disposing the dye-free cotton material into a container and adding first water at a first temperature to the container; and adding a scouring agent to the container to form a first solution, the first solution including the first water and the scouring agent, and soaking the dye-free cotton material in the first solution; degreasing, after the preparing, the dye-free cotton material by: heating the solution to a second temperature greater than the first; adding a degreasing agent to the container to form a second solution, the second solution including the first water, the scouring agent, and the degreasing agent, and soaking the dye-free cotton material in the second solution; and removing the second solution; washing, after the degreasing, the dye-free cotton material by: adding second water at a third temperature lower than the second and soaking the dye-free cotton material in the second water; reducing the temperature of the second water to a fourth temperature lower than the third temperature, and soaking the dye-free cotton material in the second water; draining the second water; and adding third water at the first temperature and soaking the dye-free cotton material in the third water; forming, after the washing, the dye-free cotton material into a dye-free medical towel. preparing the dye-free cotton material for processing by: disposing the dye-free cotton material into a container and adding first water at a first temperature to the container; and adding a scouring agent to the container to form a first solution, the first solution including the first water and the scouring agent, and soaking the dye-free cotton material in the first solution; disposing the dye-free cotton material into a container and adding first water at a first temperature to the container; and adding a scouring agent to the container to form a first solution, the first solution including the first water and the scouring agent, and soaking the dye-free cotton material in the first solution; degreasing, after the preparing, the dye-free cotton material by: heating the solution to a second temperature greater than the first; adding a degreasing agent to the container to form a second solution, the second solution including the first water, the scouring agent, and the degreasing agent, and soaking the dye-free cotton material in the second solution; and removing the second solution; heating the solution to a second temperature greater than the first; adding a degreasing agent to the container to form a second solution, the second solution including the first water, the scouring agent, and the degreasing agent, and soaking the dye-free cotton material in the second solution; and removing the second solution; washing, after the degreasing, the dye-free cotton material by: adding second water at a third temperature lower than the second and soaking the dye-free cotton material in the second water; reducing the temperature of the second water to a fourth temperature lower than the third temperature, and soaking the dye-free cotton material in the second water; draining the second water; and adding third water at the first temperature and soaking the dye-free cotton material in the third water; adding second water at a third temperature lower than the second and soaking the dye-free cotton material in the second water; reducing the temperature of the second water to a fourth temperature lower than the third temperature, and soaking the dye-free cotton material in the second water; draining the second water; and adding third water at the first temperature and soaking the dye-free cotton material in the third water; forming, after the washing, the dye-free cotton material into a dye-free medical towel.
