An adhesive for applying to a creping surface in the process for dry creping tissue paper is disclosed. The adhesive comprises cationic starch and optionally a polyvinyl alcohol and a water-soluble, thermosetting, cationic polyamide-epihalohydrin resin. The adhesive provides high adhesion and doctorability for dry creping.

Multi-layered tissue paper webs comprising biodegradable chemical softener compositions and binder materials are disclosed. The multi-layered tissue webs are useful in the manufacture of soft, absorbent paper products such as facial tissues and/or toilet tissues. The multi-layered tissue paper products contain a biodegradable chemical softening composition, preferably comprising a mixture of an ester-functional quaternary ammonium compound and a polyhydroxy compound. The multi-layered tissue paper webs also contain an effective amount of binder materials to control linting and/or to offset the loss in tensile strength, if any, resulting from the use of the chemical softening compositions. Preferably, the majority of the biodegradable chemical softening compositions will be disposed on the outer layers of the multi-layered tissue paper products where they are most effective at enhancing softness. The majority of the binder materials are also preferably disposed on the outer layers of the multi-layered product to control linting.

Soft, strong, 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 and possess biased surface properties.

Tissue paper products comprising a two component chemical softener composition and binder materials, either permanent or temporary wet strength binders, and/or dry strength binders are disclosed. The two component chemical softening composition comprises an ester-functional ammonium compound and a polysiloxane compound. Preferred ester-functional ammonium compounds include diester dialkyl dimethyl ammonium salts such as diester di(touch hardened)tallow dimethyl ammonium chloride and/or di(hydrogenated)tallow dimethyl ammonium chloride. Preferred polysiloxanes include amino-functional polydimethyl polysiloxanes wherein less than about 10 mole percent of the side chains on the polymer contain an amino-functional group.

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.

Tissue paper webs useful in the manufacture of soft, absorbent products such as napkins, facial tissues, and sanitary 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 temporary 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.

Disclosed is a process for making individualized, crosslinked fibers which includes the steps of providing cellulosic fibers, contacting the fibers with a solution containing a C.sub.2 -C.sub.9 polycarboxylic acid crosslinking agent, mechanically separating the fibers into substantially individual form, drying the fibers and reacting the crosslinking agent with the individualized fibers to form intrafiber crosslink bonds. Preferably, the crosslinking agent is citric acid, and preferably, between about 0.5 mole % and about 10.0 mole % of the crosslinking agent reacts to form the intrafiber crosslink bonds. The individualized, crosslinked fibers are useful in a variety of absorbent structure applications.
