Abstract: The specification discloses a method for laminating a synthetic film or sheet to a fibrous web. According to the method, a heat-softenable material is combined as a sheet, film, spray or powder with a continuous fibrous web in interfacial contact with fibers of the fibrous web to form a composite. The composite is then continuously conducted through an extended nip dryer where heat and pressure are applied to the composite to effect a substantial reduction in moisture content of the composite while plasticizing the heat-softenable material so that at least a mechanical bond is formed between the material and the fibers of the web characterized by an intermingling of the fibers and the heat-softenable material.

Abstract: Deinking of printed paper is accomplished by repulping printed wastepaper in an aqueous medium containing a deinking chemical. The presence of the deinking chemical causes initial agglomeration of ink particles to produce an ink pulp medium. Agglomerated ink particles are removed from the ink pulp medium by size and density separation procedures to separate coarse ink and produce a fine ink particle stream. The fine ink particle stream is recirculated to cause additional agglomeration of ink particles. The reagglomerated ink particles are removed from the fine ink particle stream by size and density separation procedures to produce a substantially ink free pulp medium. The invention provides agglomeration processes with high ink removal from printed paper.
