A cationic polyether amine dispersant for papermaking fibers comprises the polymeric reaction product of a polyether diamine, a polyether bisepoxide and a quaternary ammonium salt. The polyether diamine, the polyether bisepoxide and the quaternary ammonium salt reactants are reacted in the following molar ratios: the molar ratio of amine functionality of the polyether diamine to epoxide functionality of the polyether bisepoxide is from 0.5:1 to 2:1 and the molar ratio of the amine functionality of the polyether diamine to the epoxide functionality of the quaternary ammonium salt is from 10:1 to 40:1. The dispersant is used in stock preparation used in paper products including absorbent products as well as paperboard.

A method for forming a tubular sheet product roll includes providing a sheet product roll having a first configuration and a void, centering a rotational axis of the sheet product roll on a longitudinal axis of a first tool, and inserting the first tool into the void of the sheet product roll to define an inner diameter of the void and to form the sheet product roll having a second configuration different from the first configuration.

The present invention is directed to a foam soap delivery system. In accordance with the present invention, the system includes a paperboard core with a plurality of sheets of paper or tissue wound around the paperboard core. A dispenser is removably disposed within the paperboard core, and a water-soluble sheet soap is disposed within the dispenser.

A soft and resilient, cold-water dispersible polyurethane foam suitable for disposable personal care products is produced by the combination of corn syrup, glycerin, polyether diamine, PEG, a diisocyanate, water and a catalyst. The formulation and reaction conditions for forming the inventive foam are judiciously selected and carefully controlled to achieve water dispersibility and the desired mechanical properties. The characteristic resiliency, or percent rebound for the foams was generally over 75% and the foams are readily produced as soft foams, exhibiting a relative compression value of from 20% to 150% of that of a commercial polyurethane foam cosmetic pad which is not water dispersible. The foam may be incorporated into webs or stackable products or nestable three-dimensional products.

The drying cylinder of a papermachine is provided a creping adhesive coating including a creping adhesive resin composition and a low temperature ionic liquid or a low temperature quasi-ionic liquid, the liquid being characterized by a melting temperature of 100&#xb0; C. or less as well as low volatility.

Creping adhesive with ionic liquid

The present invention relates to the use of a quaternary ammonium complex comprising at least one non-cyclic amide as a modifier for a creping adhesive used on a creping cylinder, e.g., a Yankee dryer.

Creping adhesive modifier and process for producing paper products

An absorbent paper sheet for tissue or towel includes from about 99 percent to about 70 percent by weight of cellulosic papermaking fiber and from about 1 percent to about 30 percent by weight fibrillated regenerated cellulose microfiber which was regenerated form a cellulosic dope utilizing a tertiary amine N-oxide solvent or an ionic liquid. Fibrillation of the microfiber is controlled such that it has a reduced coarseness and a reduced freeness as compared with unfibrillated regenerated cellulose microfiber from which it is made and provides at least one of the following attributes to the absorbent sheet: (a) the absorbent sheet exhibits an elevated SAT value and an elevated wet tensile value as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (b) the absorbent sheet exhibits an elevated wet/dry CD tensile ratio as compared with a like sheet prepared without fibrillated regenerated cellulose microfiber; (c) the absorbent sheet exhibits a lower GM Break Modulus than a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber; or (d) the absorbent sheet exhibits an elevated bulk as compared with a like sheet having like tensile values prepared without fibrillated regenerated cellulose microfiber. In some embodiments, the pulp is pre-treated with debonder to enhance the wet/dry CD tensile ratio of the sheet.

Absorbent sheet having regenerated cellulose microfiber network

A wet-laid absorbent sheet includes a mixture of pulp-derived papermaking fibers and synthetic polymer fibers, a strength agent selected from carboxymethylcellulose and anionic starch as well as an epihalohydrin/amine functional wet strength resin. Also included is an anionic olefin copolymer resin effective to increase the wet/dry tensile ratio of the sheet.

Absorbent sheet prepared with papermaking fiber and synthetic fiber exhibiting improved wet strength

The present invention uses hydrophobically modified polyaminamide with standard wet strength agent to produce a softer and more absorbent paper material. The hydrophobically modified polyaminamide is substantive to cellulosic fibers, thus is able to carry polyethylene glycol esters or ethers, a non-substantive material to cellulosic fiber as stable complexes, into the paper product.

Inflated fibers of regenerated cellulose and other regenerated structures are formed from ionic liquid/cellulose dope. Fibers so produced may be incorporated into absorbent sheet with other papermaking fibers to provide softness, bulk and absorbency.
