| titleOfInvention | Carbon fiber precursor fiber and method for producing carbon fiber precursor fiber |
| abstract | An object of the present invention is to provide a carbon fiber precursor fiber suitable for producing high-strength and high-quality carbon fibers. The carbon fiber precursor fiber of the present invention that solves the above problems is a carbon fiber precursor fiber made of polyacrylonitrile fiber to which a silicone-based oil agent is adhered, and Si atoms are contained in an inner layer of 1 μm or more from the fiber surface. It is a carbon fiber precursor fiber that does not exist. In this invention, it is preferable that the adhesion amount of an oil agent is 0.01-10.0 wt%. The carbon fiber precursor fiber production method of the present invention includes a coagulation step for obtaining a coagulated yarn from a spinning solution containing an acrylonitrile-based polymer, a drawing step for drawing the coagulated yarn to obtain a drawn yarn, and an oil agent for applying an oil agent to the drawn yarn. A carbon fiber precursor fiber including a step, wherein the oil agent is applied after a stretching process of 8 times or more in the coagulation step and the stretching step. In the carbon fiber production method of the present invention, the draw ratio in the solidification step and the drawing step is preferably 80% or more of the total draw ratio. Further, in the stretching step, it is preferable to perform air stretching that extends 1.5 to 10 times in the gas phase, and it is also preferable to apply an oil agent after air stretching. [Selection figure] None |
