Abstract: An extrusion die for extruding a chemical functional additive for making a disposable paper product comprises a supply port and a distribution channel in fluid communication with the supply port. The distribution channel terminates with at least one discharge mouth having a passage cross-section therethrough. The discharge mouth comprises an entry orifice having an entry open area Ae, an exit orifice having an exit open area Ax, and a discharge distance defined between the entry orifice and the exit orifice. The exit open area Ax is greater than the entry open area Ae. This ensures that contaminants would pass through the discharge mouth, whereby plugging thereof is substantially avoided. Preferably, the passage cross-section of the discharge mouth continuously and gradually increases from the entry orifice to the exit orifice.

Abstract: Soft creped tissue paper products comprising papermaking fibers and a crepe facilitating composition are disclosed. The crepe facilitating composition comprises a bonding inhibitor, a cationic starch and a carboxymethyl cellulose. Preferably, the bonding inhibitor is a quaternary ammonium compound. The use of a bonding inhibitor, a cationic starch and a carboxymethyl cellulose results in a creped tissue paper that is both strong and soft. A creped papermaking process comprising the addition of the crepe facilitating composition is also disclosed. The crepe facilitating composition offers the potential to improve production capacity.

Abstract: Strong, soft, and low dusting tissue paper webs useful in the manufacture of soft, absorbent sanitary products such as bath tissue, facial tissue, and absorbent towels are disclosed. The tissue papers comprise fibers such as wood pulp and a non-cellulosic, water insoluble particulate filler such as kaolin clay.

Abstract: Cellulosic pulps of selected fiber morphology are disclosed having a coarseness less than a threshold coarseness level. The threshold coarseness level is a function of average fiber length. The cellulosic pulps are especially useful for producing paper structures such as tissue paper. A method for producing the cellulosic pulps is also disclosed.

Abstract: Soft creped tissue paper products comprising papermaking fibers and a biodegradable crepe facilitating composition is disclosed. The crepe facilitating composition is a biodegradable bonding inhibitor, a cationic starch and a carboxymethyl cellulose. Preferably, the biodegradable bonding inhibitor is a biodegradable quaternary ammonium compound. The use of a biodegradable bonding inhibitor, a cationic starch and a carboxymethyl cellulose results in a creped tissue paper that is both strong and soft. A creped paper process comprising the addition of the crepe facilitating composition is also disclosed. The composition offers the potential to improve production capacity.

The cellulosic pulps are especially useful for producing paper structures such as tissue paper. A method for producing the cellulosic pulps is also disclosed.

Abstract: Cellulose pulp compositions of selected fiber morphology are disclosed. Of particular interest, are morphological forms of wood fibers with the potential to achieve improved paper strength without suffering the penalty of slow drainage rate. These cellulose pulps are especially useful for efficiently producing paper structures such as tissue paper of requisite strength.

Abstract: A cellulose fiber-reinforced structure useful for building and construction made from a composition including a water-curable, inorganic binder capable of setting to form a matrix and pulped softwood fibrous material having enhanced levels of summerwood fibers.

Abstract: A paper structure having both high opacity and improved tensile strength through the incorporation of expanded fiber and an opacifying mineral pigment, such as titanium dioxide, is disclosed. The addition of expanded fiber to the paper structure makes it possible to increase the opacity of the paper through the use of the conventional mineral pigments without adversely affecting the paper's tensile strength. These opacified paper structures are especially useful for producing high quality, strong, light weight printing and writing papers which require material pigments for enhanced opacity.

Abstract: A process for making mechanically expanded fiber from fibrous material having a fibrillar ultrastructure. The expanded fiber is made by impacting the fibrous material with a plurality of fine media. Impacting by the fine media causes the fibers to expand from a fibrous form to a highly fibrillated form, wherein fibrils separate from, or become substantially disassociated from, the fibrous material ultrastructure. Cellulosic fibrous material is particularly applicable to the process. Cellulosic fibrous material is preferably impacted with fine media at least until the cellulose-containing phase of an aqueous slurry containing 0.5%, by weight, of cellulosic material will retain at least fifty percent of the initial volume of such cellulose-containing phase upon unagitated settling for a period of sixty minutes.

Abstract: A fluid collection bag has a front panel, a back panel, and closed left and right sides. The bag has a first opening, an upper chamber, and a lower chamber. The bag has a screening means between the upper chamber and the lower chamber which is a line of adherence between the front panel and the back panel extending from the left side to the right side of the bag. The line of adherence has nonadhered gaps therein.

Abstract: A tufted material is disclosed having a primary tufting substrate made up of layers of molecularly oriented film. The layers are laminated together in a generally undisturbed condition so that at least two layers have directions of molecular orientation that are perpendicular. The layers are molecularly oriented to the point of splitting parallel to the direction of said molecular orientation under the tufting needles, allowing the needles to penetrate easily, securing the tufts in place, and resulting in good tuft registration.
