Process for producing stabilized yarn for producing carbon fiber |
摘要 |
A process for producing a stabilized yarn for producing a carbon fiber is disclosed. It includes a step for thermally stabilizing a yarn by travelling a continuous fiber through the heated inside of a thermal stabilization furnace. The yarn stabilizing step is characterized in that a tension applied to the continuous fiber at a final stage of stabilizing process is higher than that applied to the continuous fiber at an initial stage of stabilizing process. An apparatus for carrying out the process is also disclosed. According to the present invention, a thermal stabilization fiber having a higher strength and a finer radius can be produced.
