Title:
PROCESS FOR MANUFACTURING CARBONIZED CLOTH
Document Type and Number:
WIPO Patent Application WO/2015/033481
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a process for manufacturing a carbonized cloth which exhibits conductivity and such softness and strength that the cloth can withstand processing. A process for manufacturing a carbonized cloth by heating a cellulose-containing cloth in a furnace, comprising: a cloth-disposing step for disposing the cloth in a furnace; a first temperature-rising step for providing an inert atmosphere to at least a region which is in the inside of the furnace and in which the cloth is disposed, and rising the internal temperature of the furnace to a level that is close to and lower than the temperature at which the cloth is carbonized; a second temperature-rising step for providing, after the first temperature-rising step, an atmosphere which is more reductive than the inert atmosphere in the first temperature-rising step to at least the region which is in the inside of the furnace and in which the cloth is disposed, and rising the internal temperature of the furnace to 1200 to 1400ºC; a keeping step for keeping, for a prescribed time, the internal temperature which has been risen to 1200 to 1400ºC in the second temperature-rising step; a temperature-lowering step for lowering gradually the internal temperature of the furnace after the lapse of the prescribed time; and a furnace-opening step for opening the furnace after the internal temperature of the furnace has lowered to about 100ºC or lower in the temperature-lowering step.
