A method for making a specialty fiber by activating pulp in an alkaline aqueous medium, then reacting it a water-soluble, multi-functional reagent able to bridge neighboring cellulose chain within a single fiber. The resultant specialty cellulose fibers have high intrinsic viscosity and may be used to make cellulose ethers, cellulose acetate, and viscose.

The present disclosure relates to a paper tube including a flavored sheet and a smoking article including the same, and more particularly, relates to a paper tube for smoking articles which includes a flavored sheet, which includes a cellulose-based polymer, a plasticizer, and a flavoring material, and which is on an inner surface, an outer surface, or both of the paper tube, and to a smoking article including the same.

The present invention relates to an aqueous solution for forming a heat-sealable coating on a paper or board surface for reducing MOSH or MOAH migration, said aqueous solution comprising a thermoplastic hydroxypropyl methylcellulose (HPMC) in an amount of from 10% to 60% (w/w), wherein said HPMC has a DS(methyl) of at least 1.0 and an MS(hydroxypropyl) of at least 0.6, wherein DS is the average number of hydroxyl groups substituted by methoxyl groups per anhydroglucose unit and MS is the average number of moles of hydroxyalkoxy groups per anhydroglucose units, and wherein the viscosity of said HPMC is from 2 mPa.Math.s to 100 mPa.Math.s, determined as a 2% (w/w) solution in water at 20 C. according to Ubbelohde.

A method of cleaning residue from a surface. A disposable cellulosic wiper is provided that includes a percentage by weight of pulp-derived papermaking fibers, and from about 10% to about 75% by weight of fibrillated regenerated independent cellulosic microfibers having a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml and having a weight average diameter of less than about 2 microns. The wiper is applied, with a predetermined amount of pressure, to a residue-bearing surface. The surface is wiped with the applied wiper, while applying the predetermined amount of pressure, to remove residue from the surface, such that the surface has less than 1 g/m.sup.2 of residue after being wiped under the predetermined amount of pressure with the applied wiper.
