Abstract: A method and apparatus for drying of a cellulosic fibrous structure having constant basis weight and/or density or multiple regions varying in basis weight and/or density. Such a cellulosic fibrous structure may have a nonuniform moisture distribution prior to drying by the disclosed method and apparatus. An equally or more uniform moisture distribution is achieved by providing a micropore medium in the air flow path which has a greater flow resistance than the interstices between the fibers in the cellulosic fibrous structure web. The micropore medium is the limiting orifice in the air flow used in the drying process. The micropore medium may be executed in a laminate of plural laminae, each of successively increasing or decreasing pore size. This arrangement provides the advantage that minimal sagging or deformation of each lamina into the next coarser lamina occurs and lateral air flow between the micropore medium and the cellulosic fibrous structure is reduced. The micropore medium may be disposed either upstream or downstream in the air flow path of the cellulosic fibrous structure to be through-air dried.

Abstract: Tissue paper webs useful in the manufacture of soft, absorbent products such as paper towels, napkins, and facial tissues, and processes for making the webs. The tissue paper webs comprise papermaking fibers, a biodegradable quaternized amine-ester softening compound, a wetting agent, and a permanent wet strength resin. The process comprises a first step of forming an aqueous papermaking furnish from the above-mentioned components. The second and third steps in the basic process are the deposition of the papermaking furnish onto a foraminous surface such as a Fourdrinier wire and removal of the water from the deposited furnish. An alternate process involves the use of the furnish containing the aforementioned components in a papermaking process which will produce a pattern densified fibrous web having a relatively high bulk field of relatively low fiber density in a patterned array of spaced zones of relatively high fiber density.

Abstract: Fibrous cellulose material useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a chemical softening composition comprising a mixture of a quaternary ammonium compound and a polyhydroxy compound. Preferred quaternary ammonium compound include dialkyldimethylammonium salts such as di(hydrogenated) tallow dimethyl ammonium chloride and di(hydrogenated) tallow dimethyl ammonium methyl sulfate. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, and polyethylene glycols and polypropylene glycols having a weight average molecular weight from about 200 to 4000. The chemical softening compositions are prepared by first mixing the polyhydroxy compound into the quaternary ammonium compound at a specific temperature range wherein the polyhydroxy compound is miscible with the quaternary ammonium compound and then diluting the mixture with water at an elevated temperature to form an aqueous vesicle dispersion suitable for treating the fibrous cellulose material.

Abstract: A limiting orifice through-air-drying apparatus for papermaking or other absorbent embryonic webs. The apparatus has a first zone and a second zone. The first zone is maintained at a differential pressure less than the breakthrough pressure, while the second zone is maintained at a differential pressure greater than the breakthrough pressure. The residence time of the embryonic web to be dried with the apparatus is maintained at preferably less than 35 milliseconds on the first zone. Using the dual zone system described above, the overall energy required to run the apparatus can be reduced.

Abstract: An apparatus and process for making the fibrous structure, having three four, and more regions. The process is similar to known papermaking techniques, but comprises the additional steps of applying a differential pressure to selected regions of the fibrous structure which are not coincident with the regions of the fibrous structure defined by the apparatus in prior steps of the papermaking process. The selective application of noncoincident differential pressure to selected regions of the fibrous structure may result in densification or dedensification of such regions.

Preferred biodegradable ester-functional quaternary ammonium compounds include diesterdialkyl dimethyl ammonium salts such as diester ditallow dimethyl ammonium chloride, diester di(touch hydrogenated)tallow dimethyl ammonium chloride and diester di(hydrogenated)tallow dimethyl ammonium chloride. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, polyglycerols having a weight average molecular weight from about 150 to about 800 and polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to about 4000. The substantially waterless self-emulsifiable biodegradable chemical softening compositions are prepared by mixing the ester-functional quaternary ammonium compound with the polyhydroxy compound at a specific temperature range wherein the polyhydroxy compound is miscible with the ester-functional quaternary ammonium compound. The resulting stable solid or concentrated fluid mixture can then be economically shipped to the consumer or ultimate user. The ultimate users of the chemical softening composition simply dilute the mixture with a liquid carrier (e.g., water) to form an aqueous dispersion suitable for treating fibrous cellulosic material. The substantially waterless self-emulsifiable biodegradable chemical softening compositions disclosed herein are primarily intended for softening disposable paper products such as tissues and towels.

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensitive resinous material to a reinforcing structure which has opaque portions, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions and also through the reinforcing structure. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.
