Patent ID: 7794565

Claim:
A method of making a soft, low lint tissue sheet, comprising: (a) forming an aqueous suspension comprising papermaking fibers; (b) depositing the aqueous suspension of papermaking fibers onto a forming fabric thereby forming a wet tissue sheet; (c) dewatering the wet tissue sheet thereby forming a dewatered tissue sheet; and, (d) applying a synthetic co-polymer to the papermaking fibers in an amount from about 0.02 to about 5 weight percent by weight of dried papermaking fibers, said papermaking fibers having a consistency from about 0.2% to about 50%, the synthetic co-polymer having the general structure: wherein: R 1 , R 2 , R 3 are independently selected from a group consisting of: H; C 1-4 alkyl radicals; and, mixtures thereof; R 4 is selected from a group consisting of C 1 -C 8 alkyl radicals and mixtures thereof; Z 1 is selected from a group consisting of: —O—; —COO—; —OOC—; —CONH—; —NHCO—; and mixtures thereof; and, Q 1 is a functional group containing at least a cationic quaternary ammonium radical, wherein w, x, y ≧1 and the mole ratio of x to (x+y) is about 0.5 or greater; and (e) drying the dewatered tissue sheet, thereby forming a dried treated tissue sheet having reduced geometric mean tensile strength as compared to an untreated tissue sheet and reduced slough as compared to a tissue sheet treated with the same amount of a commercially-available cationic oleylimidazoline debonder, wherein the amount of slough is from about 1.2 to about 3.0 milligrams.
