METHOD OF PRODUCING ACRYLIC FIBER BUNDLE AND METHOD OF PRODUCING CARBON FIBER BUNDLE
A method produces an acrylic fiber bundle that are cleaned in one or more washing baths including an inflow portion and an outflow portion for a cleaning solution; at least one of the washing baths is a counterflow washing bath in which the cleaning solution flows into from the inflow portion locate...

| description | A method produces an acrylic fiber bundle that are cleaned in one or more washing baths including an inflow portion and an outflow portion for a cleaning solution; at least one of the washing baths is a counterflow washing bath in which the cleaning solution flows into from the inflow portion located at a lower stream side position of a traveling direction of coagulated thread bundles, and flows out from the outflow portion located at an upper stream side position of the traveling direction of the coagulated thread bundles; and an average of coefficients of variation CV of linear speeds of the cleaning solution in the inflow portion of the counterflow washing bath is 0.30 or less, and an average of coefficients of variation CV of linear speeds of the cleaning solution in the outflow portion of the counterflow washing bath is 0.30 or less. |
