Abstract
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:wherein R1, R2, R3 are independently selected from a group consisting of: H; C1-4 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.
