SYNTHETIC FIBER TREATING AGENT FOR PRODUCTION OF CARBON FIBER AND METHOD FOR TREATING SYNTHETIC FIBER FOR PRODUCTION OF CARBON FIBER

摘要

PROBLEM TO BE SOLVED: To provide a synthetic fiber treating agent for production of carbon fiber, capable of simultaneously preventing fusion between frame-resistant fibers in flameproof step and occurrence of pollutant in a burning furnace in carbonization step in production of carbon fiber and a method for treating the above synthetic fiber for production of carbon fiber. SOLUTION: This synthetic fiber treating agent comprises a specific fatty acid amide crosslinked product obtained by carrying out crosslinking reaction of two molecules of polyalkylene(poly)amine difatty acid ester as a lubricant.
