OIL SOLUTION FOR PRECURSOR FIBER OF CARBON FIBER AND PRECURSOR FIBER BUNDLE OF THE CARBON FIBER

摘要

PROBLEM TO BE SOLVED: To provide an oil solution for the precursor fiber of a carbon fiber with which a high performance carbon fiber can be stably produced in good quality without fluff and thread breakage even in a calcination condition of higher thread density, higher tension and higher speed than those of conventional ones. SOLUTION: The oil solution for the precursor fiber of the carbon fiber comprises main ingredient and a temperature sensitive polymer. Precursor carbon fiber bundles for the carbon fiber are produced by using the oil solution for the precursor fiber of the carbon fiber. COPYRIGHT: (C)2006,JPO&NCIPI
