PURPOSE: To obtain the titled yarn having improved washing resistance in high yield inexpensively, by dispersing an acrylonitrile polymer and a plasticizer that is insoluble in an inorganic solvent containing thiabendazole into the inorganic solvent to give a spinning stock solution, spinning the stock solution. n CONSTITUTION: An acrylonitrile polymer is dissolved in an inorganic solvent (e.g., conc. nitric acid, etc.) Then, the polymer solution is blended with 0.05W 20pts.wt. plasticizer (e.g., chlorinated paraffin, etc.) that is insoluble in the inorganic solvent containing 0.05W3pts.wt. thiabendazole shown by the formula based on 100pts.wt. of the polymer to give a spinning stock solution, which is spun to give the aimed yarn. n COPYRIGHT: (C)1986,JPO&Japio |
