  • Continuous method of producing phthalocyanine pigment dispersions in organic solvent
    Patent number: 4522654
    Abstract: A continuous method for producing a dispersion of phthalocyanine blue pigment in an organic solvent is disclosed. The method involves the following two steps:(A) mixing a phthalocyanine crude pigment at about 10 to 50% by weight with from about 5 to 20% by weight of surfactant in a binder containing an organic solvent, and(B) continuously pumping the blend of (A) through at least two shot mills in series in which the shot grinding media range in size from 0.1 to 2.5 mm. diameter and grinding the blend until the particle size of the crude is reduced to where the solvent dispersion has suitable pigment tinctorial strength for use in inks and coatings.The dispersion of blue pigment produced by this method is especially useful in paste inks and organic solvent-based coatings.

  • Laminating
    Patent number: 4333786
    Abstract: Process for laminating. A macroapertured thermoplastic web is brought continuously into contact with the hot moving surface of a rotating roll. A fabric is pressed against the thermoplastic material on the roll and, within about five seconds, the fabric carrying the hot thermoplastic material is continuously peeled off the roll. The resulting fabric, carrying hot thermoplastic material, is then brought into contact with a preformed cellular layer.

  • Sheet material
    Patent number: 4229472
    Abstract: Upholstery material and shoe upper material made from a base sheet of criss-crossing elastomeric polyurethane fibers running parallel to the surfaces of the sheet, said fibers being bonded together at their points of contact. In one preferred form the product has a preformed skin whose thickness is less than about 100 microns and preferably less than about 50 microns, such as about 20 to 40 microns and the skin is joined to the fibers of the base sheet by spaced fingers of a binder.
