oxidized fibers of polypropylene by weaving and then carbonizing the raw fabric application_number US 68552610 A description referring to fig1 the method for making a carbon fabric of the present invention is a continuous integrated flow at first a raw fabric f 11 is obtained from oxidized fibers of polypropylene through a weaving process and rolled up into a material roll f 1 the raw fabric f 11 is then delivered in proper order through an anterior roller set 1 and a tension wheel set 2 to a high temperature oven 4 to receive a carbonization treatment the treating temperature during the carbonization treatment can be maintained constant or continuously changed or interruptedly changed further in order to prevent pyrolysis or ashing of fibers of the raw fabric f 11 during the carbonization treatment an inert gas 3 is filled in the high temperature oven 4 for protection after the carbonization treatment the raw fabric f 11 has been changed to be a carbon fabric f 21 which is then delivered through a posterior roller set 5 and then rolled up to form a roll of finished product f 2 the temperature of the carbonization treatment is within 700 2500 u00b0 c and the duration of the carbonization treatment is about within 2 240 minutes the high temperature oven.
