摘要： Tissue papers, in particular pattern densified tissue papers, having an enhanced tactile sense of softness when treated with tri-component biodegradable softener compositions are disclosed. These tri-component softener compositions comprise nonionic softeners, nonionic surfactant compatibilizers and polyhydroxy compounds. The weight ratio of the nonionic softeners to the nonionic surfactant compatibilizers ranges typically from about 10:1 to 1:10. The weight ratio of the nonionic softeners to the polyhydroxy compounds ranges typically from about 10:1 to 1:10. The tri-component biodegradable softeners are typically applied from an aqueous dispersion to at least one surface of the dry tissue paper web.

摘要： Fibrous cellulose materials 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 biodegradable chemical softening composition comprising a mixture of a biodegradable quaternized ester-amine compound and a polyhydroxy compound. Preferred biodegradable quaternized ester-amine compounds include diester dialkyldimethylammonium salts such as the 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 biodegradable quaternized ester-amine compound into the polyhydroxy compound at a specific temperature range wherein the polyhydroxy compound is miscible with the biodegradable quaternized ester-amine compound and then diluting the mixture with water at an specific temperature and pH range to form an aqueous vesicle dispersion suitable for treating the fibrous cellulose material.

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： 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.
