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： A cellulosic fibrous structure, such as paper. The fibrous structure has at least three intensively distinct regions. The regions are distinguished from one another by intensive properties such is basis weight, density and projected average pore size, or thickness. In one embodiment, the fibrous structure has regions of two basis weights, a high basis weight region and a low basis weight region. The high basis weight region is further subdivided into low and high density regions so that a fibrous structure having three regions is produced.A second embodiment is a four region fibrous structure. Two of the regions have generally equivalent relatively high basis weights and two of the regions having generally equivalent relatively low basis weights. The high basis weight regions and low basis weight regions are further subdivided according to relatively high and relatively low densities, so that when the high and low basis weight regions are permuted with the high and low density regions, four different regions result. The regions distinguished by density will have inversely proportionate projected average pore sizes.

摘要： 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.

摘要： Substantially waterless self-emulsifiable chemical softening compositions are provided 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, 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 and polyoxyethylene glycols and polyoxypropylene glycols having a weight average molecular weight from about 200 to 4000. The substantially waterless self-emulsifiable chemical softening compositions are prepared by mixing the quaternary ammonium compound with the polyhydroxy compound at a specific temperature range wherein the polyhydroxy compound is miscible with the 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 carder (e.g., water) to form an aqueous dispersion suitable for treating fibrous cellulosic materials. The substantially waterless self-emulsifiable chemical softening compositions disclosed herein are primarily intended for softening disposable paper products such as tissues and towels.

摘要： Multi-ply facial tissue paper products comprising biodegradable chemical softener compositions and a combination of a wet strength binder, either permanent and/or temporary, and a dry strength binder is disclosed.The multi-ply facial tissue paper products contain a biodegradable chemical softening composition comprising a mixture of a biodegradable quaternary ammonium compound and a polyhydroxy compound. The multi-ply facial tissue paper products also contain an effective amount of a wet strength binder, either 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 biodegradable chemical softening compositions. The use of both wet strength binder, either permanent and/or temporary, and dry strength binder also improves the retention of the chemical softening composition in the sheet. This results in improving one or more of the following properties of the multi-ply facial tissue paper product: the flexibility, the slip-stick coefficient of friction, the FFE-Index and the HTR-Texture.Preferably, the majority of the biodegradable 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 biodegradable chemical softening compositions and the wet strength binder, either permanent and/or temporary, and the 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.
