摘要：
A viscous polymer is passed through a filament or thread forming apparatus and introduced into a flowing solvent. The polymer containing solvent is then passed through a shear strain apparatus where the polymer not formed into filaments or threads is formed into long fibers and the solvent and polymer are thoroughly blended. The polymer and solvent leaving the shear strain apparatus may be introduced into a holding apparatus wherein the polymer and solvent are retained until the polymer has gelled.
