MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202647125216 A) filed by Matsumoto Yushi-Seiyaku Co. , Ltd. on October 21, 2026, for Treatment Agent For Carbon Fiber Precursor And Use Of Same.
Inventor includes Yoshida, Masahiko.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The purpose of the present invention is to provide: a treatment agent that is for a carbon fiber precursor and that can impart to the carbon fiber precursor a property such that single yarn breakages that could occur in a flame resistance imparting process are suppressed; a carbon fiber precursor obtained by the use of the treatment agent; and a method for producing a carbon fiber using the carbon fiber precursor. This treatment agent for a carbon fiber precursor contains a smooth component (A), a radical scavenger (B), and a peroxide decomposition agent (C). The radical scavenger (B) is at least one selected from a phenol-based radical scavenger (B1) and an aromatic amine-based radical scavenger (B2). The peroxide decomposition agent (C) is at least one selected from a sulfur-based peroxide decomposition agent (C1) and a phosphorus-based peroxide decomposition agent (C2).
