Patent

CA 2503751

The present invention is a soft tissue sheet having reduced lint and slough. The tissue sheet comprises papermaking fibers and a synthetic co-copolymer. The synthetic co-polymer has the general structure: Formula (I): wherein R1, R2, R3 are independently selected from a group consisting of: H; C 1-4 alkyl radicals; and, mixtures thereof; R4 is selected from a group consisting of C1 - C8 alkyl radicals and mixtures thereof; Z1 is a bridging radical attaching the R4 functionality to the polymer backbone; and, Q1 is a functional group containing at least a cationic quaternary ammonium radical. w, x, y >= 1 and the mole ratio of x to (x+y) is about 0.5 or greater.

La présente invention a trait à un nappe de tissu doux présentant un peluchage et un éboulement réduits. La nappe de tissu comporte de fibres de pâte à papier et un copolymère synthétique. Le copolymère synthétique présente une structure générale (I), dans laquelle : R?1¿, R?2¿, R?3¿ sont choisis indépendamment parmi le groupe constitué de : H, des radicaux alkyle en C¿1?-C¿4?, et des mélanges de ceux-ci ; R?4¿ est choisi parmi le groupe constitué de radicaux alkyle an C¿1?-C¿8? et des mélanges de ceux-ci?; ¿Z?1¿ est un radical de formation de pont liant la fonctionnalité de R?4¿ au squelette du polymère ; et Q?1¿ est un groupe fonctionnel contenant au moins un radical d'ammonium quaternaire cationique ; w, x, y >= 1 et le rapport molaire de x à (x+y) est égal ou supérieur à environ 0,5.
