A moisturizing tissue product that can be packaged in the same way as a non-moisturizing tissue product. With this tissue paper product in which a web obtained by folding and laminating in a pop-up configuration a plurality of sheets of tissue paper containing a moisturizing agent is stored in a rectangular-shaped paper box having an outlet on an upper surface thereof, the problem of the tissue paper is solved by this tissue paper product in which the number of plies is 2.

Zwitterionic surfactant compounds and their use in connection with absorbent paper manufacture in debonder and softener formulations. An exemplary surfactant is an imidazolinium compound of formula:

##STR00001##

wherein X is SO.sub.3, R.sup.1 is a hydrocarbyl spacer group having a chain length of from 2-6 carbon atoms, R.sup.2 is a hydrocarbyl group having from 8 to 22 carbon atoms; and R.sup.3 is an alkenylamidoalkyl moiety having from 8 to 30 carbon atoms.

The present invention describes tunable methods of treating cellulosic materials with a composition that provides increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

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 preparation method of tea residue fiber raw materials includes steps of (1) sun-drying tea residues, crushing the sun dried tea residues, and treating them with concentrated hydrochloric acid and a strong base in succession; (2) extracting water from the treated tea residues to obtain tea polyphenols and pulp respectively, cooking the pulp, and then pressing and dehydrating it to obtain coarse pulp; (3) sequentially grinding and sieving the pulp, and beating it; and (4) adding -cyclodextrin, carboxymethylcellulose sodium, and reinforced starch after the beating, adjusting the pH to 7-8, diluting, adding the tea polyphenols obtained in the second step, stirring uniformly, pressing and dehydrating, and drying to obtain the tea residue fiber raw material.

The present invention relates to a method of making a paper product having Improved printing characteristics. This is achieved by forming a fibrous substrate, and applying a surface treatment which comprises an aqueous composition. Notably, the aqueous composition includes surface enhanced pulp fibers, with the placement of the surface enhanced pulp fibers optimizing their functionality, with surface placement by use of a paper machine size press desirably facilitating a reduction in the typical starch usage. The present method comprising the steps of providing a aqueous slurry comprising a blend of cellulosic fibers and water and dewatering the aqueous slurry of cellulosic fibers and water to form a fibrous substrate. The present method further includes applying a surface treatment to the fibrous substrate, wherein the surface treatment comprises an aqueous composition including surface enhanced pulp fibers, to form a treated fibrous substrate, and thereafter drying the treated fibrous substrate to form a paper product having enhanced printing characteristics.
