Polyacrylonitrile-based carbon fiber spun yarn fabric, carbon fiber spun yarn fabric roll, and method for producing carbon fiber spun yarn fabric

摘要

PPROBLEM TO BE SOLVED: To provide a polyacrylonitrile (PAN)-based carbon fiber spun yarn woven fabric having a high grade as a spun yarn woven fabric product and a high product ratio without causing winding wrinkles on a roll inner surface (the other surface of a spun yarn woven fabric) when the spun yarn woven fabric is rolled with one surface in the PAN-based carbon fiber spun yarn woven fabric as an outer surface during rolling. PSOLUTION: The PAN-based carbon fiber spun yarn woven fabric has 2-10 mNcm bending resistance A of the one surface, 5.5-30 ratio of B/A of the bending resistance B of the other surface to that A of the one surface and preferably 3.5 m electrical resistivity value in the thickness direction, 0.20-0.50 mm thickness and 60-150 g/mSP2/SPweight.
