  • Patent number: 5389204
    Abstract: Disclosed is a process for making soft tissue paper which includes providing a dry tissue web and then applying a sufficient amount of a functional-polysiloxane softener compound to the dry web. The softener application process includes the steps of mixing a functional-polysiloxane compound with a suitable nonvolatile diluent, such as a mineral oil, forming an emulsion containing the functional-polysiloxane compound and nonvolatile diluent using a volatile solvent, such as water, and surfactant emulsifier, applying the emulsion to a heated transfer surface, evaporating the volatile solvent from the emulsion to form a film, and then contacting the dry tissue web with the heated transfer surface. Preferably, the tissue web is dried to a moisture level below its equilibrium moisture content before application of the functional-polysiloxane material.

    Abstract: In the manufacture of creped tissue products, the adhesion between the tissue sheet and the creping cylinder can be increased by applying one component of an adhesive complex to the sheet and another component of an adhesive complex to the creping cylinder. When the two components are brought into contact at the pressure roll nip, an adhesive complex is formed which adheres the sheet to the creping cylinder.

  • Patent number: 4992140
    Abstract: An improved method, and resulting product, for creping a web of papermaking fibers by adhering the web to a creping dryer and with a creping blade removing the web from the creping dryer which provides increased absorbency with less reduction in strength. The improvement comprises reducing the cohesive forces between the fibers to a greater extent than reducing the adhesive forces between the web and the creping dryer accomplished by applying a fluid at least primarily comprising water overall to the side of the web away from the creping dryer in sufficient quantity and at a position to accomplish the improved results. The method is particularly useful in the practice of wet creping wherein the web is creped from the creping dryer at a dryness of from 45% to 60%.

  • Patent number: 4986882
    Abstract: Processes are described for making highly absorbent tissues and towels by wet-laying pulps comprising particular polycarboxylate polymer-modified fibrous pulps such as mildly hydrolyzed methyl acrylate-grafted softwood kraft pulps; these pulps have distinct protonated and alkali-metal-cation-exchanged states. The wet-laying processes are adapted to exploit the very different behavior of the polymer-modified fibrous pulps in function of the two states. The preferred wet-laying processes described herein are continuous processes embodying one or more on-line chemical treatment steps which chemically switch state of the polymer-modified fibrous pulp component in a wet web on the papermaking machine to improve the processing thereof by averting or minimizing tendencies to mechanically or thermally degrade.

  • Patent number: 4964933
    Abstract: An insulating polyolefin laminate paper and a method for producing such a paper in which first and second fiber paper layers are laminated to a polyolefin film layer. The fiber paper layers have an impermeability of 20 to 4000 Gurley-seconds. At least one of the fiber paper layers is mechanically deformed in such a manner that irregularities are produced having a depth of 2 to 50% of the thickness of the fiber paper layer. The mechanical deformation is accomplished prior to lamination. Before lamination, the water content of the fiber paper layers is controlled to be no more than 4%. Preferably, the thickness of the fiber paper layers is at least 30 microns. Furthermore, an electric power supply cable includes an insulating polyolefin laminate paper as an insulating layer.

  • Patent number: 4795530
    Abstract: A process for making a soft, strong cellulosic sheet weighing from about 2 to about 15 pounds per 2880 sq. ft., comprising selectively treating a face surface of a cellulosic fibrous web with a dilute aqueous solution of a chemical debonding agent in an amount effective to soften a surface zone of the web proximate the treated face surface, whereby a composite strong zone/soft surface zone structure results, with the soft surface zone thereof including the treated face surface and being from about 10 to about 40% of the total thickness of the web, and with the strong zone being effectively untreated by the agent. The cellulosic sheet made by this process is characterized by a strong inner surface zone of from about 50 to about 90% of the total thickness of the sheet, and a soft and pleasing-to-the-touch outer surface zone comprising the remainder of the thickness of the sheet.
