METHOD FOR PRODUCTION OF CARBONIZED CLOTH, AND CARBONIZED CLOTH PRODUCED BY THE METHOD

摘要

Disclosed is a method for producing a carbonized fiber cloth by carbonizing a raw fiber cloth under heating, wherein the raw fiber cloth is a woven fabric, a knitted fabric or a woven and knitted fabric composed of a cellulose fiber yarn. The method comprises the steps of: rolling-up the raw fiber cloth and placing a roll of the cloth in a heat-resistant cylindrical container so that the roll of the raw fabric cloth is surrounded by the cylindrical container in a semi-hermetic state under an oxidizing atmosphere; continuously heating the heat-resistant cylindrical container having the roll of the raw fiber cloth contained therein in a heating furnace to a final heating temperature ranging from 1000 to 1600°C; and retaining the roll of the cloth at the final heating temperature for a predetermined time period. The method enables to produce a carbonized cloth having excellent electrical conduction property, heat resistance, electromagnetic wave absorption property and the like and also having excellent mechanical strength and flexibility in a relatively simple and economically advantageous manner.
