Abstract
The carbonization of cellulose fiber fabric comprises an initial stage of heat treatment up to 250° C. to 350° C., with a relatively high mean temperature rise speed of 10° C./min to 60° C./min, an intermediate stage up to 350° C. to 500° C. with a lower mean temperature rise speed of 2° C./min to 10° C./min, and a final stage up to 500° C. to 750° C. with a mean temperature rise speed that is again raised to 5° C./min to 40° C./min.
