1. A carbonized fabric production method for producing a carbonized fabric by heating a fabric containing cellulose in a furnace, the method comprising:
a fabric arrangement step of arranging the fabric in the furnace; a first temperature-increasing step of increasing a temperature of at least a fabric-arrangement region in the furnace to a temperature that is closely below a carbonizing temperature of the fabric, while at least the fabric-arrangement region in the furnace being adjusted to be in an inert atmosphere; a second temperature-increasing step of, after the first temperature-increasing step, increasing the temperature of at least the fabric arrangement region in the furnace to a temperature in a range of from 1,200° C. to 1,400° C., while at least the fabric arrangement region in the furnace being adjusted to be in a reducing atmosphere relative to at least the inert atmosphere in the first temperature-increasing step; a maintenance step of maintaining, for a predetermined period of time, the temperature in the furnace which has reached a temperature in a range of from 1,200° C. to 1,400° C. in the second-temperature increasing step; a temperature-decreasing step of gradually decreasing the temperature in the furnace, after a lapse of the predetermined time; and a furnace-opening step of opening the furnace after the temperature in the furnace has become about 100° C. or less in the temperature decreasing step. |
