Title:
TREATMENT AGENT FOR CARBON FIBER PRECURSOR AND CARBON FIBER PRECURSOR
Document Type and Number:
WIPO Patent Application WO/2020/241603
Kind Code:
A1
Abstract:
This treatment agent for a carbon fiber precursor comprises a nonionic surfactant, amino-modified silicone, and dimethyl silicone which has a kinematic viscosity at 25°C of 5 to 200 mm2/s. The mass ratio of the content of the amino-modified silicone to the content of the dimethyl silicone may be such that the amino-modified silicone/the dimethyl silicone = 99.9/0.1 to 90/10. This carbon fiber precursor is characterized by having the treatment agent for a carbon fiber precursor adhered thereto.
