Abstract: Starch fibrids useful in enhancing the physical properties of non-woven webs, e.g., paper, are produced by a process which comprises providing an aqueous, alkaline solution of a water-insoluble starch in a finely divided form, e.g., in the form of an aerosol, and introducing the finely divided starch solution into an agitated, aqueous precipitating medium comprising a precipitating salt to thereby produce starch fibrids characterized by having both film and fiber morphology. The starch fibrids are recovered from the salt-containing liquid and may be incorporated into paper to improve the physical properties thereof.
