METHOD OF PRODUCING ACRYLIC YARN TOW AS CARBON FIBER PRECURSOR

摘要

PROBLEM TO BE SOLVED: To provide a method of producing acrylic filament tow as a carbon fiber precursor that causes no damage of single filament at the squeezing of the tow and provides carbon fiber of high performance.;SOLUTION: In the process for producing acrylic filament tow as a carbon fiber precursor, the precursor acrylic fiber tow is treated with finishing oil by allowing the tow to pass through the finishing oil tank whereby the oil film is formed between the tow filaments and the route of the tow is fixed.;COPYRIGHT: (C)2004,JPO
