Abstract: PURPOSE:To provide a good package form even for a large package, stably deliver yarns and prevent the occurrence of fluff or yarn breakage in a carbonization step, by applying a specific amount of a special composition to yarns after flameproofing treatment and winding up the resultant yarns. CONSTITUTION:The following composition in an amount of 0.2-5wt% is applied to flameproofed fiber yarns (oxidized fiber yarns) obtained by heating a fibrous precursor in an oxidizing atmosphere and the resultant yarns are wound up into a package, which is then transferred to a carbonization step (graphitization step). The flameproofed fiber yarns delivered from the package are then heat- treated at a high temperature. The composition contains ethylene oxide adduct of butanediol and/or trimethylolpropane ethylene oxide adduct with an amount of added ethylene oxide within the range of 5-15 as an essential component.

Abstract: PURPOSE:To suppress orientation relaxing in flameproofing and obtain the titled precursor, having a specific strength, maximum draw ratio and maximum developing tension, by finally drawing fibers consisting of acrylonitrile, etc., heat-setting the drawn fibers and relaxing the fibers in, before and after the above-mentioned treatment. CONSTITUTION:A polymer, having at least 5.5g/d strength and containing >=90wt% acrylonitrile is spun, drawn and finally drawn to give a precursor, which is then subjected to heat-setting treatment at the maximum temperature of 150-220 deg.C and relaxed in, before and after the heat-setting treatment within the range of 3-10% to afford the aimed precursor, having 5.5-7g/d strength, 115-140% maximum draw ratio during residence in hot air at 240 deg.C for 2min and 0.3-0.4g/d maximum developing tension when treated in hot air at 240 deg.C for 2min and useful for carbon fibers.
