Abstract

Produces paper and like products of modified surface properties by depositing electrostatically charged particles of dry starch on a water-wet web which may still be on the wire of a Fourdrinier machine. The starch particles are deposited as uniformly distributed segregated particles which remain on the surface of the paper to be swollen with the water of the web as the web is dried to bind the surface fibers to the body of the paper. The adhesive function of the starch does not require the particles to be gelatinized to the point of rupture and the paper, especially newsprint, retains its porosity. The lack of penetration of the starch into the body of the paper and its presence in the form of separated particles emphasizes the surface binding action of a small amount of starch.
