    摘要: A differential density single lamina web of cellulosic fibers comprises at least two pluralities of micro-regions disposed in a non-random and repeating pattern: a first plurality of high density regions and a second plurality of low density regions. The high density regions comprise cellulosic fibers comprising fluid latent indigenous polymers (FLIP), such as hemicelluloses and lignin. The fibers of the high-density regions are FLIP-bonded, i.e., bonded together by a process of softening, flowing and immobilization of the FLIP between the cellulosic fibers of the high density regions. The process for making the web comprises the steps of providing a plurality of papermaking fibers comprising FLIP; providing a macroscopically monoplanar papermaking belt having a web-facing surface and deflection conduits; depositing the plurality of the cellulosic fibers on the papermaking belt to form a web; heating the web to a temperature sufficient to cause the FLIP contained in a first portion associated with the web-facing surface of the belt to soften; impressing the web-side surface of the belt into the web; immobilizing the flowable FLIP and creating FLIP-bonds between the fibers comprising the first portion of the web.

    摘要: A process and an apparatus for making a foreshortened paper web are disclosed. A wet web disposed on a fluid-permeable papermaking fabric is being pressed between two parallel and mutually opposed first and second press surfaces, the first press surface contacting the web, and the second press surface contacting the fabric. In the continuous process, the press surfaces, the web and the fabric move in a machine direction. Under pressure, at least selected portions of the web become densified and adhered to the first press surface which can be treated with a creping adhesive. The first surface is heated to create a temperature differential between two surfaces. The temperature differential causes the water contained in the web to move from the web into the fabric, thereby drying the web. After the web is released from the pressure, the web is foreshortened either by creping or by transferring the web to a slower moving transfer fabric. Creping is performed with a creping doctor blade juxtaposed with the creping surface having the web adhered thereto. A creping adhesive may be deposited on the creping surface according to a predetermined pattern. The creping surface may comprise the first press surface. Optionally, the web may be calendered after being foreshortened.

    摘要: A differential micro-regions single lamina fibrous web comprises at least two pluralities of micro-regions disposed in a non-random and repeating pattern: a first plurality of micro-regions comprising fibers interconnected with a fiber-bonding substance, and a second plurality of micro-regions, preferably not interconnected with the fiber-binding substance. The fiber-binding substance is selected from the group consisting of hemicelluloses, lignin, polymeric extractives, and any combination thereof. The fibers of the first plurality of micro-regions are bonded together by a process of softening, flowing, and immobilization of the fiber-binding substance between the cellulosic fibers. The process for making the fibrous web comprises the steps of heating the web containing the fiber-binding substance to a temperature sufficient to cause the fiber-bonding substance to soften; pressurizing the fibrous web thereby causing the fiber-binding substance to flow and interconnect those fibers which are mutually juxtaposed in the first plurality of micro-regions; and then immobilizing the fiber-binding substance thereby creating fiber-bonds between the fibers which are interconnected in the first plurality of micro-regions.

    摘要: A micropore drying apparatus having a variable wet flow resistance. The flow resistance preferably decreases in the machine direction. The micropore drying apparatus may comprise a single integral unit having an decreasing wet flow resistance from the beginning to the end of the unit. Alternatively, the micropore drying apparatus may comprise a plurality of discrete units, each unit having a successively lesser flow resistance than that of the preceding unit. Alternatively, a hybrid arrangement may be used wherein each discrete unit has a successively decreasing flow resistance within that unit. The micropore drying apparatus may comprise one or more micropore drying media. The micropore drying media have pores which allow air flow therethrough. The pores are disposed in a grid, to form a field of pores. The decreasing flow resistance may preferably be provided by adjusting one or more of said pores, which affect the flow resistance through a single pore or through the entire field of the pores.

    摘要: A dual intensive property tissue. The tissue has a first set of intensive properties including density, surface area, thickness and void volume as presented to the consumer. The consumer plastically activates the tissue by pulling it in tension. A series of slits 44 or other lines of weakness elongate in a direction parallel to the line of tension, allowing the tissue to achieve a second state of intensive properties. The value of the second state of intensive properties is different after activation. The change in value of the intensive properties allows for economies in shipping, where a higher density product is shipped to the consumer. At the point of use, the consumer activates the product to achieve the increase surface area and lower density. The increase in surface area and concomitant decrease in density provides for increased efficacy in cleaning. The plastically activatable state may be provided by a series of slits 44 or other lines of weakness in the tissue. The tissue may comprise cellulosic and/or synthetic fibers. The tissue may be used as a facial tissue, bath tissue, paper towel, napkin, body wipe, mophead, etc.
