A high strength, non-woven fibrous material is prepared by (a) mixing an aqueous slurry of a negatively charged, water-insoluble natural or synthetic fiber or blend of fibers with an amount up to the fiber charge reversal point of a structured particle latex having pH independent cationic charges bound at or near the particle surface to form an aqueous suspension, (b) draining water from the aqueous suspension to form a wet web (c) wet pressing the web and (d) drying the web by heating. |
