ABSTRACT:
Disclosed are abrasive wiping articles, e.g., nonwoven, preferably paper towels, which comprise an absorbant nonwoven substrate having printed thereon a cured scrubbing bead mixture which comprises a) certain carboxylated, ionically-charged polymeric abrasive particles, b) a carboxyl group-containing polymeric adhesive material, and c) an amino-epichlorohydrin, e.g., Kymene.RTM., cross-linking agent. The polymeric abrasive particles range in size from about 20 to 400 microns and have a Knoop hardness of from about 4 to 25. The polymeric adhesive material, upon curing, has a Knoop hardness of from about 0.5 to 17.
Preferred wiping articles of the foregoing type have a pattern of the scrubbing bead mixture printed onto from about 20% to 70% of the surface area of a paper substrate with the abrasive particles affixed to the substrate in such a manner that their exposed portion extends for a distance of from about 40 to 300 microns above the surface of the paper substrate. Wiping articles of this type are especially useful for removing soil and stain from hard surfaces with the polymeric scrubbing particles thereon being especially resistant to removal during use.
Also disclosed is a process for preparing abrasive wiping articles as hereinbefore described. Such a process involves printing a pattern of the scrubbing bead mixture onto the paper substrate, drying the printed substrate and then curing the solid components of the scrubbing bead mixture to affix the abrasive scrubbing particles to the substrate. Curing of the particular scrubbing bead mixture employed can take place at room temperature.
