  • Patent number: 8142612
    Abstract: A method of making a cellulosic web having an elevated absorbency. The method includes (a) forming a nascent web having an apparently random distribution of fiber orientation from a papermaking furnish, (b) non-compactively drying the nascent web to a consistency of from about 30 to about 60 percent, (c) thereafter, transferring the web to a translating transfer surface that is moving at a first speed, and (d) fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric. The creping step occurs under pressure in a fabric creping nip defined between the transfer surface and the creping fabric, wherein the fabric is traveling at a second speed that is slower than the speed of the transfer surface. The fabric pattern, nip parameters, velocity delta and web consistency are selected such that the web is creped from the transfer surface and redistributed on the creping fabric.

    Abstract: A creped paper product is provided according to the invention. The creped paper product comprises a result of creping a web of fibers comprising synthetic fibers to provide a creped paper product having a stretch of at least 3% in the machine direction according to TAPPI test T494. The web of fibers can include about 0.5 wt. % to 100 wt. % synthetic fibers based on the total weight of the fibers. In addition, the web of fibers can contain about 0.5 wt. % to about 10 wt. % of synthetic fibers and about 90 wt. % to about 99.5 wt. % of cellulosic fibers. When the web of fiber includes a mixture of synthetic fibers and cellulosic fibers, the creped paper product can be provided having a tear strength in the machine direction according to TAPPI test T494 at least 10% greater than an otherwise identical creped paper product that does not contain synthetic fibers.

    Abstract: A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a throughdrying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the throughdrying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the throughdrying fabric when the dried sheet is applied to the surface of the creping cylinder.

As a primary pressing member subject to concentrated force it is 0.040 inch thick. One or both opposed retarder members of a bladed microcreper are of the plastic. Thermoplastics meeting wear and friction limits, e.g. ultra high density polyethylene, are employed. Primary member extensions, some having openings, slots or holes serve as flexible retarders to engage treated material. Parallel slots, preferably formed by water jet cutting, defining machine-direction fingers provide particular advantages, often greatest when the fingers begin upstream of the creping cavity, and stated dimensional limits observed. By a load-spreading surface, the thermoplastic primary member is restrained without distortion.

  • Publication number: 20110011545
    Abstract: An absorbent cellulosic sheet having variable local basis weight includes a papermaking-fiber reticulum provided with (i) a plurality of cross-machine direction (CD) extending, fiber-enriched pileated regions of relatively high local basis weight interconnected by (ii) a plurality of elongated densified regions of compressed papermaking fibers. The elongated densified regions have relatively low local basis weight and are generally oriented along the machine direction (MD) of the sheet and have an MD/CD aspect ratio of at least 1.5. The products are most preferably prepared by way of a compactive dewatering/wet crepe process.

  • Patent number: 7854822
    Abstract: A plasticizing formulation for producing plasticized fluff pulp. The plasticizing formulation, which preferably is an aqueous solution, includes a primary plasticizing agent, and optionally a secondary plasticizing agent. Preferably, the primary plasticizing agent is 1,4-cyclohexanedimethanol, and the secondary plasticizing agent is triacetin. When the plasticizing formulation is applied to a cellulosic fluff pulp, a plasticized fluff pulp is produced. The resultant plasticized fluff pulp may have one or more of the following: reduced Kamas energy, Mullen strength, and fiber knot and nit contents, when compared to the base cellulosic fluff pulp fiber that is not plasticized.

    Abstract: The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing. The present invention is also a method for retaining a high percentage of softening agent within a paper web that includes such an agent. Further, the present invention is a soft absorbent paper product having a high void volume. Finally, the invention is also a method for producing a soft, absorbent, and near premium paper product having a high void volume using an undulatory crepe blade having a multiplicity of serrulations in its rake surface which presents differentiated creping angles and/or rake angles as to the paper being creped.

  • Publication number: 20100282423
    Abstract: A method of making a fabric-creped absorbent cellulosic sheet comprising: a) compactively dewatering a papermaking furnish to form a nascent web having an apparently random distribution of papermaking fiber; b) applying the dewatered web having the apparently random fiber distribution to a translating transfer surface moving at a first speed; c) fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a patterned creping fabric, the creping step occurring under pressure in a fabric creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the transfer surface and redistributed on the creping fabric to form a web with a drawable reticulum.

  • Publication number: 20100263817
    Abstract: Tissue products are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue web as the web is being formed. Alternatively, the additive composition may be topically applied to the web in a post processing operation. For instance, in one embodiment, the additive composition may be applied to the web as a creping adhesive during a creping operation.

  • Patent number: 7807022
    Abstract: A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a through drying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the through drying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the through drying fabric when the dried sheet is applied to the surface of the creping cylinder.

  • Patent number: 7807023
    Abstract: Sheet-like products are disclosed containing an additive composition. In accordance with the present disclosure, the additive composition is applied to a creping surface. A base sheet is then pressed against the creping surface for contact with the additive composition. The base sheet is then creped from the creping surface causing the additive composition to transfer to the base sheet. In particular, the additive composition is transferred to the base sheet in amounts greater than about 1% by weight, such as from about 2% to about 50% by weight. The additive composition can comprise, for instance, a thermoplastic polymer resin containing an aqueous dispersion, a lotion, a debonder, a softener, or mixtures thereof.
