Abstract
The manufacture of paper-like and textile-like sheet materials by the use of fibrids which have been obtained by dissolving poly(amide-imide) resins in an organic solvent, mixing the resulting solution with a liquid which is a non-solvent for the polymer and introducing the resulting solution into a liquid precipitation medium while exposing it to shearing forces.
