    摘要: Disclosed herein is a cellulosic fibrous structure having multiple regions distinguished from one another by basis weight. The structure is a paper having an essentially continuous high basis weight network, and discrete regions of low basis weight which circumscribe discrete regions of intermediate basis weight. The cellulosic fibers forming the low basis weight regions may be radially oriented relative to the centers of the regions. The paper may be formed by using a forming belt having zones with different flow resistances. The basis weight of a region of the paper is generally inversely proportional to the flow resistance of the zone of the forming belt, upon which such region was formed. The zones of different flow resistances provide for selectively draining a liquid carrier having suspended cellulosic fibers through the different zones of the forming belt.

    摘要: A cellulosic fibrous structure having two regions distinguished from one another by basis weight. The first region is an essentially continuous high basis weight network. The second region comprises a plurality of discrete low basis weight regions. The cellulosic fibers forming the plurality of second regions are generally radially oriented within each region. The cellulosic fibrous structure may be formed by a forming belt having zones of different flow resistances arranged in a particular ratio of flow resistances. The zones of different flow resistances provide for selectively draining a liquid carrier through the different zones of the belt in a radial flow pattern.

    摘要: Biodegradable chemical softening compositions are provided comprising a mixture of a quaternized ester-amine compound and a polyhydroxy compound. Preferred biodegradable quaternized ester-amine compounds include diester dialkyl 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, and polyethylene glycols and polypropylene glycols having a weight average molecular weight from about 200 to 4000.The biodegradable chemical softening compositions are prepared by first mixing the quaternized ester-amine compound into the polyhydroxy compound at a specific temperature range wherein the polyhydroxy compound is miscible with the quaternized ester-amine compound and then diluting the mixture with a liquid carrier at a specific pH and temperature range to form an aqueous vesicle dispersion suitable for treating fibrous cellulosic material. The biodegradable chemical softening compositions disclosed herein are primarily intended for softening disposable paper products such as tissues and towels. However, the biodegradable chemical softening compositions can also be used to soften fibrous cellulosic materials in textile form.

    摘要: Multi-ply facial tissue paper products comprising chemical softener compositions and a combination of a wet strength binder, permanent and/or temporary, and a dry strength binder is disclosed.The multi-ply facial tissue paper products contain a chemical softening composition comprising a mixture of a quaternary ammonium compound and a polyhydroxy compound. Preferred quaternary ammonium compounds include dialkyl dimethyl ammonium salts such as di(hydrogenated)tallow dimethyl ammonium chloride and/or di(hydrogenated)tallow dimethyl ammonium methyl sulfate. Preferred polyhydroxy compounds are selected from the group consisting of glycerol, polyglycerols having a weight average molecular weight of from about 150 to about 800, polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to 1000. The multi-ply facial tissue paper products also contain an effective amount of a wet strength binder, permanent and/or temporary, and a dry strength binder to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the chemical softening compositions. The use of both wet strength binder, either permanent ot temporary, and a dry strength binder also improves the retention of the chemical softening composition in the sheet.Preferably, the majority of the chemical softening compositions will be disposed on the outer layers of the multi-ply facial tissue paper products where they are most effective. In other words, the chemical softening compositions and the wet strength binder, permanent and/or temporary, and a dry strength binder can be selectively distributed within the multi-ply facial tissue paper product to enhance the softness, absorbency and/or lint resistance of a particular layer or ply.

    摘要: 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.

    摘要: A process for making an absorbent structure having a capillary substrate and regions of osmotic absorbent on the capillary substrate. The osmotic absorbent is cured from a liquid precursor applied to the capillary substrate. The capillary substrate has regions of topographically different elevations, taken normal to the plane of the capillary substrate. The capillary substrate is passed through a gap between a transfer roll and an anvil roll in a printing apparatus. The transfer roll has at liquid precursor on its periphery. The liquid precursor is applied to only the topographically elevated regions of the capillary substrate which contact the periphery of the transfer roll. By changing the topography of the capillary substrate, the liquid precursor can be applied to the capillary substrate in different pattern, without changing the transfer roll. This arrangement allows for absorbent structures having various patterns of osmotic absorbent on a capillary substrate to be readily produced with great flexibility in the manufacturing process.
