  • Publication number: 20050145353
    Abstract: Spirally wound single-ply web products having a chemical additive applied to at least one surface exhibit desirable roll bulk characteristics and softness properties. The rolled products can be made from a single-ply tissue web formed according to various processes. Once formed, the web is subjected to a shear-calendering device that increases the Fuzz-On-Edge properties of the web and preserves the bulk of the web when wound. The shear-calendered web then has a chemical additive applied to at least one surface by a non-compressive application method helping to maintain the Fuzz-On-Edge properties of the web.

  • Publication number: 20050136265
    Abstract: The present invention is a polysiloxane treated hydrophilic tissue sheet having a polydialkylsiloxane content of about 0.4% or greater by weight of dry pulp fibers. The polysiloxane treated hydrophilic tissue sheet may also have a wet out time after aging 20 days at about 130° F. of about 10 seconds or less.

  • Publication number: 20040234804
    Abstract: Tissue products are described that have been topically treated with a chemical additive, such as a softener. The softener may be, for instance, a polysiloxane. The polysiloxane is topically applied to a tissue sheet, such as a single ply sheet, so as to form a Z-directional gradient in the sheet. Particular, most of the polysiloxane remains on the surface of the tissue product as opposed to migrating to the center of the sheet. In this manner, tissue sheets are formed with improved softness at lower levels of polysiloxane and without the need for applying any surfactants to the sheet. A system for applying chemical additives to tissue sheets is also described. The system includes a chemical additive applicator, such as a meltblown die that emits the chemical additive through a plurality of orifices. In one embodiment, the system includes a device for periodically cleaning the orifices during application of the chemical additive.

  • Patent number: 6805965
    Abstract: A method is disclosed for topical application of compositions containing a chemical additive onto a paper web. The present invention is also directed to paper products formed from the method. In general, the method includes the steps of extruding a composition containing a chemical additive through a melt blown die and then applying the composition to a moving paper web. In one embodiment, the chemical composition is extruded into fibers and applied to the paper web. The chemical composition can contain, for instance, various additives, such as a polysiloxane softener.

  • Publication number: 20040099392
    Abstract: A method is disclosed for topical application of compositions containing a chemical additive onto a paper web. The present invention is also directed to paper products formed from the method. In general, the method includes the steps of extruding a composition containing a chemical additive through a melt blown die and then applying the composition to a moving paper web. In particular, the method provides for the application of tacky compositions to a web through a melt blown die while avoiding die tip clogging. In one embodiment, the chemical composition is extruded into fibers and applied to the paper web. The chemical composition may contain, for instance, various additives, such as a polysiloxane softener and one or more beneficial agents.

  • Publication number: 20040074622
    Abstract: A method for applying a softening composition to a paper web of a tissue product is provided. The softening composition is applied primarily to the elevated regions of the tissue product. The application of the softening composition in this manner allows for the use of hydrophobic softeners, such as amino-functionalized polysiloxanes, in an amount of from about 0.05% to about 5% by weight of the tissue product while maintaining a Wet Out Time of less than about 10 seconds.
