PURPOSE:To obtain subject yarn having antimicrobial action with excellent washing durability by treating acrylonitrile-based yarn having a chlorine- containing monomer with an aqueous solution prepared by adding a specific amide-based compound to a specific antimicrobial agent solution and heat- treating. CONSTITUTION:Acrylonitrile-based yarn having 15-55wt.% chlorine-containing, preferably vinylidene chloride polymer or vinyl chloride polymer is immersed and treated with an aqueous solution as an antimicrobial agent prepared by adding 0.75-10% owf dimethylamide compound and/or sulfoxide compound as an additive to a solution containing an organosilicon quaternary ammonium salt, heat-treated at 90-130 deg.C to give chlorine-containing polyacrylonitrile-based yarn having antimicrobial action sufficiently standing repeated washing. Vat curing method, vat steam method, etc., are preferable as the treating method. |
