  • Patent number: 6884468
    Abstract: A method comprising: (I) providing a composition; (II) applying the composition to a paper substrate; and (III) forming a paper coating on the paper substrate; wherein the composition comprises a blend of polymers, wherein the blend of polymers comprises a vinyl aromatic-acrylic polymer and a vinyl aromatic-diene polymer, wherein the vinyl aromatic-acrylic polymer comprises a reaction product of vinyl aromatic and an alkyl (meth)acrylate, and the vinyl aromatic-diene polymer comprises a reaction product of vinyl aromatic and a conjugated diene, wherein, based on a solids weight of all polymers in the blend of polymers, the vinyl aromatic-acrylic polymer is present in the blend of polymers in an amount from 50% to about 95% and the vinyl aromatic-diene polymer is present in an amount from about 5% to 50%.

  • Patent number: 4421600
    Abstract: A system for producing a bulky, soft and absorbent paper web wherein the web is directed through a first nip formed by two dewatering felts, a second nip formed between a dewatering felt and an imprinting fabric of a specified character, and a third nip formed between the imprinting fabric and creping surface.

  • Patent number: 4309246
    Abstract: A bulky, soft and absorbent creped paper web is manufactured by supporting an uncompacted wet web of principally lignocellulosic fibers on an imprinting fabric having compaction elements, for example knuckles formed at the warp and weft crossover points of the filaments of an open mesh fabric. The imprinting fabric has a surface void volume of from about 15 cc/m.sup.2 to about 250 cc/m.sup.2, preferably from about 40 cc/m.sup.2 to about 150 cc/m.sup.2, and a compaction element contact area constituting from about 5% to about 50%, preferably from about 20% to about 35%, of the total surface of the imprinting fabric. The web is selectively mechanically dewatered or pre-dried by passing the web through a first compression nip formed between the imprinting fabric and a dewatering felt at a pressure in a range from about 20 pli to about 600 pli so that significant compacting of the web occurs in the vicinity of the compaction elements.
