Pulp containing hydrophilic debonder. Breese, John A. (Kimberly-Clark Corp., USA). U.S. US 4432833 A 21 Feb 1984, 7 pp. Cont.-in-part of U.S. Ser. No. 150,885, abandoned. (English). (United States of America). CODEN: USXXAM. CLASS: IC: D21H003-12. NCL: 162158000. APPLICATION: US 82-352399 25 Feb 1982. PRIORITY: US 80-150885 19 May 1980. DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Treating cellulose pulp with quaternary ammonium compds. 3010-24-0 and 89687-21-8 are cas registry numbers of chemicals which are used as reagents here. gave products having reduced interfiber bending while maintaining hydrophilic properties for use in manuf. of sanitary napkins, diapers and paper towels. Thus, an aq. slurry of southern softwood kraft pulp was treated with 0.2-2.5% polypropylene glycol mono[3-(diethylmethylammonio)propyl] ether chloride [9042-76-6], formed into hand sheet and dried to give a specimen with basis wt. 60 lb/3000 ft2, burst strength 4.19 psi, tensile strength 3.90 lb/in., H2O absorbency 0.68 cm/s 1/2 and diaper fluff absorbency 47.6 mL/s 1/2. .

DOCUMENT TYPE: Patent CA Section: 43 (Cellulose, Lignin, Paper, and Other Wood Products) Section cross-reference(s): 42 A sheet of cellulosic material, e.g. paper or paperboard, comprising a base material which contained hydrophobic contaminants (stickies), was coated to cover these imperfections by use of a coating compn. comprising an aq. suspension contg. a pigment, an adhesive, and a small amt. (0.2-2.0 wt.% based on the wt. of the dry pigment) of a surfactant. The surfactant is preferably a non-ionic surfactant having an HLB value in the range 8-14. Thus, a coating compn. comprising hydrous kaolin clay 90, calcined kaolin clay 10, latex adhesive (polymer solids) 11, Na CM-cellulose 1, and surfactant 1 part by wt. was prepd. 9042-76-6 and 9003-55-8 which are cas registry numbers of substances are two of reagents here. and dild. with sufficient water to give a low shear viscosity. The compn. was coated (10 g/m2) onto sheets of paperboard which was light brown in color and which had visible spots caused by stickies. The coating adhered well to all parts of the surface of the paperboard, including the locations of the stickies, and the defect spots were concealed by the coating. .
