PROBLEM TO BE SOLVED: To prevent the fibrillation of a solvent-spun cellulose fiber in any process involved in the fiber including dyeing finishing process and repeated washing process by treating the fiber in an aqueous solution containing chlorohydrin or glycidyl group-bearing compound (s), a compound exhibiting alkalinity in its aqueous solution and a neutral salt. SOLUTION: The fibrillation of a solvent-spun cellulose fiber is prevented by treating the fiber at >=40 deg.C (pref. 60-100 deg.C) for 10-90 min in an aqueous solution containing a reaction promoter composed of at least one compound selected from the group consisting of compounds each having 2-4 chlorohydrin or glycidyl groups in one molecule (e.g. polyethylene glycol dichlorohydrin or ethylene glycol diglycidyl ether), a compound exhibiting alkalinity in its solution (e.g. sodium hydroxide) and a neutral salt such as anhydrous sodium sulfate. |
